LB-A Polyolefin Shrink Film /
LB-A Polyolefin Shrink Film
LB-A is a widely used polyolefin shrink film with good stiffness，toughness，optics and excellent sealing & shrinkage.
It is a general-purpose heat shrinkable film covers a broad spectrum of shrink warp applications, provides premium appearance display and good protection. Due to balanced stiffness & toughness，decent sealing and wide shrink temperature range, it is capable to work on all kinds of shrink warp machines, including high speed packing system.
