Skin Packaging and blister packaging differences: A skin packaged product has a thin clear plastic film that has been shrunk over the product and adhered to the board. A blister pack is a hard plastic pocket that is in a similar but not perfect shape of the product. In many ways, a skin packaged product is superior to blister packaging. You can change the configuration and size of the product and still use the same board. This is great for products like circular saw blades, screw drivers, automotive parts, tools, etc. Different sized products can be put on the same board saving you money. Blister packaging would require a new die and pocket for each size.
