LB-L High-speed Packaging Polyolefin Shrink Film

LB-L is a specially designed shrink film for high-speed packing applications, with excellent transparency, good shrinkage, consistently strong seals and exceptional tensile strength.

This film is especially suitable for high-speed pillow packaging, with good heat sealing and electrostatic sealing performance, which can reach maximum 250 packs per minute. It allows for short dwell times that maximize production and increase plant efficiency. This film is mostly used in the form of unfolded single ply reel type.
