When you receive your roll of custom labels, you probably don’t think too much about the liner. All you care about is that your labels look great. But the release liner, as it is known, plays a vital role in supporting your labels so they can be peeled off easily. Have you ever wondered how the labels can be so easily removed from the liner, but very difficult to remove from any other surface?
The secret ingredient is silicone, a versatile polymer material that has excellent adhesive repelling properties. The liners for the materials we use here are all paper based, with a layer of silicone added to the paper to support the labels, protect the adhesive, and allow easy label application.
Release liners come in different thicknesses and with different properties. Our standard white BOPP material comes with a 50lb white paper liner, which is coated with a layer of silicone and has excellent strength and tear resistance. It is a good general purpose liner that is suitable for hand or automatic application.
If you order our Estate #9 textured cream material you will notice a different liner. The liner here is a 44lb brown paper liner that is specially designed for high speed automatic application. This is because the Estate #9 material is popular in the wine industry, and most labels for wine are applied by machine.
So next time you receive a roll of labels from us, take a moment and look at the release liner, it provides a very important role for self-adhesive labels. Without it you really wouldn’t be able to use your labels.
