Protective films coat stickers and other sensitive substances to protect them until needed. They are used in medical supplies and electronics and can be made from coated papers, films, and plastics. Release liner manufacturers produce high-performance adhesive liners and can develop appropriate liners for customers. Research and development is ongoing, and waste concerns can be addressed through using recycled materials or biodegradable liners.
A protective film is a layer of material that can coat stickers or other sensitive substances to protect them until someone actually needs them. These materials are used in applications ranging from medical supplies to electronics. A number of manufacturers make them for in-house use, and they also supply companies that need release liners and don’t make them themselves. Their components may vary, depending on the intended application.
A classic use for release liners can be seen in adhesive bandages such as those used in first aid kits. When someone removes the wrap to expose the bandage, one or more strips of material must still be removed to expose the adhesive. The backing is coated with an agent that allows it to release easily from the adhesive when pulled, but it won’t peel off on its own. It keeps the adhesive sterile and usable until someone is ready.
Coated papers, films, and specialty plastics can be used to make release liners. They can be plain or printed with a variety of designs. The coating used on the adhesive side is specially formulated for a particular adhesive. The pressure holds the adhesive liner in place until someone gently pulls it off, in which case it should lift cleanly to expose the adhesive. Release liner designers can develop application products such as masking tape, decals and overlay stencils until needed, and backing adhesives.
Release liner manufacturers often produce adhesives. Their knowledge of the chemistry behind their adhesive products allows them to produce high performance adhesive liners that match their adhesive product line. In other cases, a customer will need to send in a sample of the adhesive and should discuss the need so the company can develop an appropriate liner. It may also be possible to mix additives into the adhesive to facilitate the use of a release liner.
Research and development into such products is an ongoing activity at some companies interested in developing better adhesives and related products. Some companies may also have waste concerns, which can be addressed through options such as using recycled materials in the production of release liners or recommending biodegradable liners to customers. Because these materials are designed to be disposable, steps to limit their impact on the environment can focus on using fewer new materials or limiting waste at the other end of the product cycle if possible.
