Mail is made of lightweight polyethylene resin, the most widely used plastic in the world. Polyethylene is used to make everything from shopping bags to food packaging cleaners, detergent bottles to car fuel tanks.

Designed for easy storage:

Spatial relationships don't have to be your forte to understand why shipping boxes, even when collapsed, take up more space than plastic bags. Cardboard can make a lot of mess in the packaging process and turn your performance area into a small…dangerous area. 

Polymail, on the other hand, is easy to place and pack and doesn't require much of the assembly that is commonly done with corrugated cardboard boxes. However, if you are also looking for custom printed poly mailers then visit https://copackinc.com/plastic-bags/poly-mailers.
