What Is a Label Release Liner?

Label liner materials

There are a variety of different release liners available for labels and stickers. Depending on your label application and specific product features, there might be an option that works better for you. The most common release liner materials are paper or PET film.

1.PET release liners

PET liners are primarily important for high-speed automatic labeling machines. They are made from polyester film, which is thinner than paper liners so you can roll more labels on each roll. This reduces roll changes during high-speed or large-volume label applications, and it also reduces waste. Since the rolls can be smaller, this can also save storage space and shipping costs.

PET release liners are also ideal for things like labeling beer cans that require a wet application. They generally have fewer breaks on automatic machines than paper liners, which saves time and money.

2.Paper release liners

Paper liners are one of the most common release liners and the most economical. aper release liners have a silicon coating to prevent the label adhesive from sticking to the paper underneath below. That way you can separate your label and liner easily when ready for application.

They offer good tensile strength and won’t break when converting into labels or being wound on a label applicator. While they are strong under tension and can perform on high-speed packaging lines we don’t recommend them for things like wet applications.
