After packaging a product in a heat shrink bag, how do you seal it? Here's a simple method using a hand-operated PVC heat shrink bag sealing machine:
1. This is a roll of PVC shrink film. I've cut a suitable size for the object I want to package.
2. This is one side that has been cut and sealed with the sealing machine. Then we put the object inside the bag.
3. After putting the object in the bag, seal this side using the same method as in step 2.
4. Trim (remove) the four corners.
5. Then use a heat sealer or blow sealer.
