LB-AF Anti Fog Cross-Linked Shrink

LB-AF is a cross-linked shrink film with anti-fog properties,, which is the ideal film product for fresh produce and other fresh & frozen packaging applications. Examples include fresh fruits and vegetables, as well as a wide range of processed foods. It prevents water drops build up on the film surface which allows refrigerated products to remain visible in the retail shelf display.

Due to the crosslink technology, it also has outstanding gloss & clarity, good toughness, strong & durable seals and high shrinkage to allow excellent packaging performance.

This flexible film is compatible with a wide range of shrink packaging equipment, including high speed flow-pack machine.
