LB-C Cross-Linked Shrink Film /

LB-C Cross-linked Heat Shrink Film

LB-C is a cross-linked polyolefin shrink film. While possessing the typical thermal shrink characteristics of polyolefins, this multifunctional shrink film boasts excellent tear resistance, durable and high-strength sealing properties, and superior shrinkage rates. Its enhanced toughness and tear resistance make the packaging more robust. The exceptional sealing effect ensures a firm and long-lasting seal, completely eliminating the "threading" phenomenon at the sealing points. The outstanding shrinkage rate (up to 80%) delivers perfect shrink packaging performance, allowing the film to conform more closely and provide an outstanding display for your products. In addition to delivering excellent packaging results for conventional products, it is also an ideal choice for combined packaging. LB-S is suitable for various manual, semi-automatic, and automatic packaging machines.
