Transparent hand stretch film made of polyethylene (PE).
The stretch film is required to protect the highly elastic rubber of the HutlinerPacker® and the pipe sealing cushions (straight bubbles) against contaminations.
Grease in particular reacts with the high content of natural rubber in the top surface of the packer, which can lead to a formation of tears. Dried-in resin residue impairs the elasticity of the rubber.
The stretch film sold by Schwalm is specially designed for the use of multi-diameter packers and impresses thanks to its high elasticity.
