Polyolefin unperforated shrink bags
The best way to preserve soap is to wrap if after a good cure. Less oxygen equals less oxidation giving it a much longer shelf life.
Trick: When heat sealing your soap, leave about half an inch extra slack to compensate for shrinkage, use a low setting on the heat gun, hit the seams first, and hold the heat gun farther away then you think you should. Wearing cotton gloves helps with your protection.
Used for packaging smaller items. Use a hair dryer to shrink around your item. Set your temperature to high. It is preferred to use a heat gun as they have higher heat. PVC film shrinks to fit. Speed your packaging operations with these bags. Recommended for soap, bath bombs or other bodycare products. Crystal clear packaging in seconds.
These bags did not shrink at all. I wrapped bath bombs and proceeded to shrink them, no luck. Will not be buying them again
