LB-K Economical Cross-Linked Film

LB-K is a cross-linked polyolefin shrink film with perfect combination of performance and high yield. It has comparable performance as LB-C, but with cost savings through higher yield. The higher yielding with low gauges provide lower film cost per package and the high efficiency during packaging process due to less roll changes. This film is suitable for nearly all sealing systems because of its high strength and high seal performance.
