Release solutions for composite layup, bonding, and processing
Composite materials need release surfaces that can support resin systems, adhesive layers, prepregs, and technical laminates during storage and processing. S&S Paper Industries supplies paper and film liner options for manufacturers working with engineered composite components.
Built around real converting and end-use demands
Composite production often involves pressure, heat, resin flow, sensitive surfaces, and strict dimensional requirements. A liner must protect the material and separate cleanly without disturbing the composite layer. We help manufacturers choose liner constructions based on resin chemistry, processing temperature, required stiffness, and removal behavior.
Film liners are useful when tear strength, smoothness, and dimensional control are critical. Paper liners can provide economical release performance for many prepreg, adhesive film, and lamination steps. Differential release can also support multi-layer composite builds.
