An Introduction to release liners

A release liner serves as an intermediate during many manufacturing processes, carrying and protecting adhesives to stick one product to another product or surface. Release liners are usually a paper or film layer with a release coating, securely holding the sticky material and helping it remain sticky until it's ready to be released for the next step its needed for. For instance, when you peel the backing off a band aid or sticker, that backing is a release liner which helps the band aid or sticker remain sticky until used.

Release liners come in various types, such as film-based, paper-based, poly-coated paper-based options and even unique substrates with metallized papers/films as their base. These release liner substrates have specially engineered release coatings, often made of silicone, which enable the liner to release its contents only when needed.

However, some release liners can still fit their release function without using silicone coatings. Instead, they rely on specific surface characteristics of the substrate to achieve the desired release properties, eliminating the necessity for additional coatings. These non-silicone-based release liners are considered as highly specialized and are designed to serve specific purposes.

Wide Market Variety of End Usages

Pressure-sensitive adhesives rely on a liner to carry adhesives during converting and application processes. These adhesives find global applications in pressure-sensitive graphics and labels and self-adhesive tapes, where the liner's strength plays a crucial role in adhesive coating, die-cutting, and converting. In pressure-sensitive labeling, the liner must be carefully designed to meet the demands of high-speed automated application equipment, ensuring seamless and efficient label application.

Release liners play a crucial role in the medical and hygiene markets, where they find applications in various products such as electrodes, wound dressings, transdermal patches, diapers, and feminine care products. In medical applications, the manufacturing process requires higher levels of cleanliness, and the products must adhere to specific regulatory standards.

For these medical products, the removal of the release liner is typically done by hand, often by the end consumer. Therefore, maintaining consistent release properties is of utmost importance to ensure a smooth user experience.

Industrial release liners serve essential roles in various high durability applications, including building and construction. They find usage in roofing shingles, weatherproofing, and insulation products. Moreover, release liners play a critical role in the manufacturing of composite pre-preg materials used in aerospace, wind energy, recreation, and automotive sectors. In these applications, the release liner is exposed to significant temperature fluctuations, demanding exceptional dimensional stability to ensure smooth and precise manufacturing processes. These specialized applications highlight the importance of reliable and robust release liners in industrial settings.
