Industrial release liners

Release liners (also called liners or carriers) are substrates with low-surface-energy (typically silicone-treated) that carry adhesives, films or products that must be transferred or peeled off in final application. Typical applications: carrier for pressure-sensitive adhesive tapes (such as Scotch 3M), liner for self-adhesive labels, carrier for automotive PPF films (Level A Application 34), liner for medical adhesives, temporary substrate in industrial lamination and coating processes. Most release liners are made of siliconized paper or siliconized PET film. PU appears in specialized applications where unique properties are needed: liners for products requiring excellent surface finish (automotive, electronics), liners with superior mechanical durability (multiple uses in industrial processes), liners with resistance to specific solvents.
