The shrink film uses a double-cycle hot air to form a hot air flow that crosses in the region to ensure a balanced temperature in the shrinkage zone. Why do you want to ensure the temperature balance of the pof shrink film? As a Shrink Film Supplier, let's explain it to you.
Polyolefin Shrink Film is a material that replaces PVC shrink film. Since PVC is low in toxicity and generally not recommended for food packaging, the substrate replacing PVC is replaced by PE.

In general, the hand-wrapped film uses a finished film with a large lateral shrinkage.
