Pressure sensitive paper is everywhere but it’s not something we look for in everyday life. You could have noticed it when you made your coffee this morning, maybe held it when you cooked soup for lunch yesterday, or even had recycled it after drinking a water bottle. Pressure Sensitive Label Paper and Films are everywhere and wrapped around everything, promoting the brands and companies we know and love today.
But what makes a Pressure Sensitive Label stick? While it may seem simple, Pressure Sensitive Labels consist of four individuals layers:
- Liner – The backing material (made of paper or plastic film) that is the base for the remaining three layers. This is the part that is thrown away after being used for countless applications.
- Release Coat – A special coating is then applied to the top surface of the liner in an effort to oppose the sticky adhesive that will be applied in the next layer. Once the product is finished, the release coat will allow the face stock (the main label or brand art) and adhesive to easily peel away from the liner and eventually be applied to a given product.
- Adhesive – The glue that holds the face stock (the label) to a given products is important and often varies upon a client’s request. The adhesive formula can be constructed to fit the client’s cares and needs through the variables within their requested application: the products material (paper, metal, plastic, etc.), the label application temperature, product storage temperature, product’s surface texture, wet or dry environments, etc.
- Face Stock – The label material is used to construct the client’s requested brand or image on various materials such as paper, plastic films, foils, fabrics, and laminates. This is the part you see on your shampoo bottle.
