MWP vs MWPE vs MWPO – Which Waterproof Labels Will Win?

Wednesday, May 16th, 2018

If you’ve been searching for waterproof labels, you may have noticed that we supply three marine labels that are very similar. Our polyester labels (MWP), polyethylene labels (MWPE), and polyolefin labels (MWPO) ARE very similar. They all have a matt white finish, are all waterproof labels, and all have a marine standard permanent adhesive. So how do you know which waterproof label is the right one for you?

The answer lies in your label application. Each material has its own properties and characteristics that are better suited to certain applications compared to the others. It just depends on what you need your waterproof labels to be able to do…

Waterproof Labels That Will Stay Stuck

While all three have a marine standard adhesive, the different materials cause slight variations in the level of tack (stick). This is most noticeable when labelling more unusual materials and surface types.

For example, if you apply all three onto a completely flat, clean metal surface you would see very little difference. On rough materials or curved surfaces, the polyethylene would cope the best with any surface variations. The polyolefin would be next best, followed by the polyester.

If your label application involves a curved surface or unusual materials (such as fabrics or building materials) you may wish to choose polyethylene.

Waterproof Labels That Will Bend & Stretch

One of the most notable differences between these three materials is how well they bend and stretch. Polyester is a rigid material and will not stretch at all. Polyolefin offers better flexibility and stretch, while polyethylene is the most flexible and stretchy material of the three.

The material you choose depends on whether you need waterproof labels that ARE flexible or ARE NOT flexible. For example, to label curved surfaces you need waterproof labels that will conform to the shape of your items. If you apply a rigid label material to a curved surface, one of two things will happen:

  • Your sticky labels won’t conform to the shape of your items. You may find areas where your labels aren’t stuck to the item. Alternatively, there won’t be sufficient contact to allow a successful adhesive bond to form at all and your waterproof labels will fall off immediately.
  • You will be able to temporarily force your sticky labels to conform to the correct shape BUT the memory of the material will cause them to return to their original flat state – overcoming the strength of the adhesive bond and resulting in your waterproof labels slowly peeling away from the surface.

Alternatively, you may be looking for waterproof labels that won’t tear or deform easily, even when used as long life tracking labels on items that are regularly moved or handled a lot. In this case, you will need waterproof labels that offer good resistance to tearing and stretching.

If your label application involves curved surfaces you may wish to choose polyethylene (as the most flexible option), while polyester is the best bet if you need tough and durable waterproof labels that will resist the wear and tear of long term applications.

Waterproof Labels That Will Print Out Perfectly

While all three printer labels are suitable for use with standard desktop printers, some are easier to print than others.

First you need to consider whether you have an inkjet printer or a laser printer. MWPE and MWPO are laser labels and inkjet labels; they can be printed with a laser printer or an inkjet printer. MWP are laser labels and can ONLY be printed with a laser printer.

Next you need to take into consideration the specification of your printer. Waterproof labels are thicker than standard paper labels and so you need to check that your printer has a media bypass tray (a secondary tray designed specifically for thicker materials) as well as the weight of materials that your printer will accept. If your printer cannot handle heavier materials, you will need to choose a thinner material to ensure that you can print your waterproof labels.

Polyethylene is a VERY thick material and requires careful handling; if your printer is not designed to handle very thick materials, you may find that you struggle to produce a consistent print quality on your waterproof labels (if you manage to print them at all). Polyester, however, is much thinner making it a much easier and more reliable material to print. Polyolefin is a thicker material BUT not as thick as polyethylene, which makes it a perfect compromise between MWP and MWPE.

Waterproof Labels That Will Fit Into Your Budget

If you’re ordering fewer than 500 sheets there is absolutely no difference between the three options. If you’re looking to buy in bulk (and on a budget) there is a difference in cost; MWP is the most expensive option, followed by MWPE, and then MWPO.

Ester, Ethylene, Or Olefin: Which Poly Will Make You Jolly (Happy With Your Label Purchase)?

Wednesday, May 3rd, 2017

If you’ve taken a look at our range of waterproof labels, you may have noticed that we offer THREE different types of Marine Labels; MWP, MWPE, and MWPO.

You may also have noticed that all of these labels are waterproof labels that are extremely tough and durable, and suitable for a whole range of label applications – including both indoor and outdoor uses.

All of which may have left you confused as to which of these waterproof labels would be the best for you – this post aims to give you a quick fire guide to the differences between these three materials to help you make up your mind.

THE MATERIALS
The principle difference between these three label products is the face material used to make the labels; MWP is made with polyester, MWPE is made with polyethylene, and MWPO is made with polyolefin. All three are similar synthetic materials but have slightly different properties that give each label certain advantages (or disadvantages) over the others depending on the application you have in mind.

The key differences are as follows:
MWP: this material is white in colour, less flexible, and thinner than the other two materials (it also offers slightly better chemical resistance than MWPE and MWPO, although all three offer excellent resistance to most common chemicals).
MWPE: this material is slightly off-white in colour, is the most flexible, and the thickest of the three materials.
MWPO: this material is white in colour, is more flexible than MWP but less flexible than MWPE, and is thicker than MWP but thinner than MWPE.

THE ADHESIVE
All three of these labels are made with a marine adhesive, which conforms to the BS5609 part 2 standard for marine immersion – this standard is awarded to adhesives that are suitable for use in marine conditions and is also considered a marker for high quality adhesives that are tough, durable, and suitable for a variety of applications and environments.

Due to the flexibility of each material type, however, under certain circumstances the adhesive strength of these labels does differ slightly – making MWPE the stickiest of the three, followed by MWPO, and then MWP. This is because MWPE and MWPO have the flexibility to allow these labels to conform better to different surface types – including rough, curved, or unusual surfaces – while the rigidity of the MWP can cause it to struggle slightly on certain surfaces. Therefore, while you would see very little difference between the three if you were to apply them all to a clean, flat metal surface, you may get different results on a curved metal surface.

THE PRINTING EXPERIENCE
While MWPE and MWPO can both be printed on inkjet printers or laser printers, MWP can only be printed using a laser printer. The MWP labels are the easiest to print, however, because the thickness of MWPE and MWPO requires a little more care when printing (with some smaller printers being unable to process materials of this thickness at all).

THE PRICE
If you are looking at smaller quantities (i.e. less than 500 sheets), there is absolutely no difference between these three product ranges so the label you choose will entirely depend on the characteristics and properties you want your labels to possess. Once you move into bulk boxes of 500 sheets, there is some slight variation in price with MWPO being the most cost-effective choice and MWP being the most expensive choice.

If you’re still confused, we’ve put together a simple table to show the differences between our marine labels (with 1 being the best option for that particular feature).

FAQ – Should I Choose Paper Or Polyester Labels / Coloured Or Transparent Labels / Gloss Or Matt Labels?

Thursday, September 22nd, 2016

At Label Planet, we like to offer our customers the best possible variety of label options to choose from; in addition to providing as many label sizes as we can, we also like to offer those sizes in a range of materials (where possible), so that customers can find the perfect label for their particular application.

To find the perfect label, there are THREE main choices that you need to make – label size, adhesive, and material.

The first two are usually easier to deal with because they are the most strongly influenced by the practical requirements of your label application; you choose the size that fits and the adhesive that will allow your labels to stay in place (or come away) as needed.

For example, you HAVE to choose a label size that will fit neatly onto your items and that is big enough to hold all of the information or design work that you want to add. You also need to make sure that adhesive you choose is suitable for the surface type you are labelling (e.g. by choosing a stronger adhesive for curved surfaces and unusual materials), suitable for the environmental conditions of your application (e.g. by choosing a deep freeze adhesive for items that will be stored in a freezer), and suitable for the application in hand (e.g. by choosing a removal adhesive if you need temporary labels that won’t do any damage when they are removed).

When it comes to choosing the right material, however, it can be a bit more difficult – while there are some label applications with practical factors that will determine the type of material you can use (e.g. you will HAVE to choose one of our polyester or polyethylene materials if you want waterproof labels), it is much more likely that you will end up choosing the material that best fits your own personal preferences for what you want your labels to look like.

And this is where some of our customers get a bit stuck! So, we’ve put together a quick-fire guide to the different material choices that are available when you order labels from Label Planet to help you find the one for you!

Paper Or Polyester (Or Polyethylene)?
Paper is the most common material used to make labels and is likely to be the sort of label that you are most familiar with. Polyester and polyethylene are synthetic materials with a broader range of properties and characteristics than those offered by paper; the most obvious example is their durability, which allows them to last longer than paper labels and to cope with a much more varied set of conditions and environments than paper labels.

Benefits and Disadvantages of Paper Labels
As a material, paper is much more readily available than polyester and polyethylene, which means that it is much more likely that your chosen paper labels will be available for same day despatch from stock (in either packs of 25 sheets or boxes of 500 sheets). We are also able to offer a larger range of material options (including colours, gloss and matt finishes etc) compared to our range of synthetic labels and they tend to be more flexible when it comes to printer compatibility, with many of our paper labels being suitable for use with laser printers or inkjet printers. Finally, paper labels will always be the cheaper option if you need to work to a strict budget.

Benefits and Disadvantages of Polyester Labels & Polyethylene Labels
As we’ve mentioned, synthetic materials are much more durable than paper labels and have the particular benefit of being waterproof. They can be used in both indoor and outdoor environments, where they may be exposed to or immersed in water and are excellent for use as long lasting or tracking labels, where it is vitally important that the information on a label should remain completely legible and firmly in place for as long as possible, even if the item is moved around or handled a lot.

However, polyester and polyethylene are also more expensive materials than paper and are not available in as wide a range of label sizes as our paper labels; while the most popular sizes are available to order for same day despatch from stock in packs of 25 sheets, some sizes are only available as “made to order” items, which have a despatch estimate of up to five working days.

You also need to bear in mind the fact that the majority of our synthetic materials can ONLY be printed with a laser printer; if you need to use an inkjet printer, you will only be able to choose between Gloss Clear Polyester or Matt White Polyethylene.

Colour Or Transparent?
Using a coloured label or a transparent label is an instant way to make your labels (and items) more eye-catching and creative in appearance. Coloured labels give you a burst of colour as the background to your labels, while transparent labels are ideal if you need to add a label to an item made of a transparent material, that have a decorative surface that you don’t want to cover up, or if you want to create a dramatic “floating text” effect.

Benefits and Disadvantages of Coloured Labels
A quick and easy way to add a decorative touch to any item, coloured labels are the easiest way to make your labels stand out; you can use colour to draw attention to important information, match your company branding, or create a more decorative and creative finish to your items that is simply a bit more fun!

You should keep an eye on the printer compatibility of the coloured labels you are interested in; while our pastel coloured labels and brown Kraft labels can be printed with either an inkjet printer or a laser printer, our metallic labels and fluorescent labels can only be printed with a laser printer (although you can, quite happily, handwrite any of our coloured labels!).

Some of our coloured labels are available in packs of 25 sheets (for same day despatch from stock), while others will only be available as “made to order” items – with a minimum order quantity of 500 sheets. You may also need to think carefully if you want to mix and match sizes and colours; we cannot split a pack or box between two or more different sizes and/or colour BUT we may be able to offer you a better price if you get in touch with us and let us know what sizes and colours you need.

Benefits and Disadvantages of Transparent Labels
Transparent labels are a brilliant way to add a decorative finish to any item; they’re a really creative tool, especially if you need to label transparent items (such as glassware), want to create a “floating text” effect, want to avoid covering up existing designs on a surface, or to avoid the problem of colour matching your label to your items. For example, they’re extremely popular for use as address labels on wedding invitations, where the stationery and envelopes used to make these invitations are often highly decorative in nature (with colours chosen to match a specific theme or colour scheme or perhaps with a decorative textured surface for extra decoration) – and the last thing you want to do is to plaster a label all over your carefully chosen invitations.

Again, you may need to consider any budgetary restrictions that you have; all of our transparent labels are made of polyester, which as we have already mentioned is a more expensive material than paper.

Gloss Or Matt?
Gloss labels have a decorative bright and shiny finish, while matt labels have a “dull” non-shiny finish; generally, people choose the finish that best fits with the overall look or appearance that they are trying to create for their items. While you may choose to match your finishes (e.g. a matt label for a matt surface / a gloss label for a gloss surface), you could also use the opposite finish to help your labels stand out (e.g. a matt label on a gloss surface / a gloss label on a matt surface). We also offer a third finish as a compromise between the two in the form of a Semi-Gloss finish.

There aren’t really any major advantages or disadvantages of choosing one finish over the other because this choice is based much more firmly on your own personal preferences. The gloss materials do tend to be slightly more expensive than matt materials (due to the more specialised coatings that are used to create the high shine of a gloss finish). The paper gloss (for laser printers) and semi-gloss materials have an extra benefit because the coatings used to make these particular materials offer some limited protection against water, which means they can be wiped clean and dry if they are lightly splashed with water (which is why we refer to these products as “Splashproof”) – this makes them an ideal compromise if you need waterproof labels but cannot afford the fully waterproof solution offered by using polyester or polyethylene labels.

Labels For The Great Outdoors

Tuesday, June 3rd, 2014

Some of our customers are looking for labels that can be used outdoors, which means they have a number of variables to take into consideration. So here’s the Label Planet checklist of things to think about when buying labels for the great outdoors.

– THE MATERIAL
For starters, your labels need to be made of a material that is going to be able to survive outdoors. This means that a simple paper label is unlikely to do the job. So you need to be looking for a tough, durable material that is also waterproof.

– THE ADHESIVE
You’re also going to need a good, strong adhesive to make sure that your label stays put. Make sure that the labels you buy have a strong permanent adhesive that is at least waterproof, if not an enhanced marine quality adhesive.

– THE PRINT
With regards to the old question of inkjet versus laser print, it should be noted that laser print is waterproof while inkjet print is not. This is because inkjet inks are water based and will run or smudge if they get wet. However, you will also need to bear in mind the consequences of leaving a label outside and, in particular, the impact that natural sunlight will have on print. UV rays in natural sunlight will cause print to fade over time. There are some ways of improving the UV resistance of print, but many of these options are provided by professional printers rather than being available to individual or independent end users.

So, which labels from Label Planet can be used outdoors?

If you need labels for the great outdoors, visit our Waterproof Labels page, and take a look through the “Waterproof Synthetic Labels” section of the page.

A Label Never Forgets

Tuesday, January 7th, 2014

All labels have a “memory”; meaning that if they are stretched or distorted in any way from their original dimensions, they will try to return to their original shape.

Different materials have different strengths of memory; for example, our polyester labels all have stronger memory strengths than our paper labels.

Label memory can cause problems if you need to apply a label to an uneven surface – particularly cylindrical objects (such as tubes and bottles) or around a tight corner. The label will try to return to a flat state and so fights against the adhesive; if a label’s memory is stronger than the adhesive, the label will begin to return to its original state and its edges will curl up or the whole label will peel off entirely.

So how can you avoid problems with label memory?
1. If you have to label an unusual surface, make sure you choose a label material with a low memory strength, such as paper labels.
2. Alternatively, make sure you choose a label with a high strength adhesive, such as high tack labels.
3. You could even try to combine the two and choose a label such as our polyethylene labels, which are more flexible than our polyester labels (giving them a lower memory strength) and have a high quality marine standard adhesive.
4. You could also try to improve the bond formed by the adhesive on a label. All adhesives have an initial tack and an ultimate adhesion; the initial tack describes how well the adhesive sticks to a surface on initial contact. Once a label has been applied, the adhesive continues to cure and strengthen until it reaches ultimate adhesion (the strongest bond that a particular adhesive can achieve). In order to speed up the curing process you could try applying extra pressure when sticking the label onto an object or make sure that the label is applied and/or stored at a higher temperature. This will allow the adhesive to strengthen faster than usual, meaning it is more likely to have formed a strong bond by the time the memory of the label starts to work against the adhesive.
5. Finally, if you are applying a label to a cylindrical object, you could try choosing a larger size of label that will overlap itself when wrapped around the object. Labels will usually start to curl at the edges and so sticking one edge of a label over another will help to prevent the label peeling off. If there isn’t a large enough label to wrap around a particular object, you can always try using two labels and overlapping them over each other.

Waterproof Labels: Inkjet versus Laser Printing

Thursday, January 17th, 2013

Customers who want waterproof labels often ask us about the difference between using waterproof labels with an inkjet or a laser printer.

If customers need the label AND the print to be waterproof then they will have to use a LASER printer. The inks used for inkjet printing are water-based and so will smudge when exposed to water.

We have a number of different waterproof labels available for use with a laser printer, depending on the finish required:

– Transparent Polyester Labels in a Gloss Finish or a Matt Finish

– Matt White Polyester Labels in a Gloss Finish or a Matt Finish

Silver Matt Polyester Labels

Matt White Polyethylene Labels

If customers require waterproof labels that will definitely be exposed to water, particularly in outdoor or marine conditions, we recommend Matt White Polyester Labels or Matt White Polyethylene Labels as these are supplied with a marine tested (BS5609) adhesive.

We supply removable waterproof labels in Gloss Transparent Polyester or Matt White Polyester.

We also stock Transparent Polyester Labels with a Gloss Finish for use with inkjet printers. These labels are suitable for use in dry conditions or as waterproof labels when there is no need for printing onto the labels themselves.
