Abstract
A polyethylene shipping bag having an internal nylon barrier coating which permits packaging of materials which normally migrate through polyethylene. The coating is flexographically applied from a nylon solution in a lower aliphatic alcohol with up to 15% water to a polyethylene film which has been previously treated to make it receptive to printing ink. The bag may be single ply or double ply and may have a filling valve.
