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).

Blockout/Opaque Labels – We’ve Got You Covered

Wednesday, August 27th, 2014

Whether you need to cover up a mistake or replace some old text with something new, opaque or “Blockout” labels are an ideal solution.

Opaque labels are designed specifically to block out anything beneath them, so you can only see the label itself and anything that has been printed on it.

We have a range of opaque labels, which are made of matt white paper with an opaque or “blockout” backing that prevents anything from showing through the paper layer.

We sell this label in a variety of sizes – although we cannot do bespoke sizes – at a minimum order quantity of 500 sheets. You can see the available sizes on our Opaque Label Product Page.

As some customers only need a few labels and find that 500 sheets is just a bit too much, we do have a few alternative suggestions:

1. If you’ve got a steady hand, you could simply try layering our standard labels until any existing print is no longer visible.

2. Try our Gold or Silver labels; the particular finish of these labels creates an opaque or block out effect, so they will do the same job as our Opaque labels – albeit with a slightly more eye catching finish.

3. As a compromise, you could try our Matt White Polyethylene labels; as this is a thicker material than standard paper it is more efficient at covering up existing print than a standard label. However, it isn’t a perfect solution and (depending on how bold the print beneath is) you may find that the print below is still slightly visible.
