How to Use the Shrink Wrap Bags:

• Step 3. Heat the bag with a heat gun or a professional Tunnels Heat Shrink Packing Machine  

• Step 4. Until the shrink bag completely clings to the product

Tips:

If it is used for DIY package, the heat gun can not stay in the same area for too long. It is necessary to keep moving the heat gun to avoid excessive heat expansion.

Ordinary household hair dryers can't  work because it can't heat up to the 340 °F required for shrinkage!!!

During production, a row of small pinhole vents have been made on the two side of the bag for easy and perfect shrinkage,and the holes won't be obvious after the heat sealing is completed.

Size suggestion:

If it is a standard rectangular item, and  L, W, and H represent the length, width, and height of the product respectively, then the required 

length of the POF bag should be greater-or-equal (L+H+1.8) inch, and the required width should be (W+H+0.4) inch to (W+H+0.75) inch.

Tools needed to complete the shrinkage: 

A heat gun or a professional Tunnels Heat Shrink Packing Machine, and a heat sealer.
