SPS Peelable Sealants

SPS concentrates can be used as a direct replacement for polybutylene peelable sealants.

SPS concentrates are designed for formulating peelable sealants. Sealants made using SPS products can be processed on conventional blown and cast film extrusion and coextrusion equipment. The distinguishing feature of SPS concentrates is their ability to yield sealants with easy peel characteristics when heat-sealed to itself. Products are available for polyethylene- (e.g., EVA) and ionomer-based sealant systems.
