Abstract

A high strength plastic bag is formed from two sheets of polymeric material. The sheets are folded, machined, and heat sealed to form a receptacle portion, a flap for covering an opening to the receptacle portion and handles to facilitate handling of the bag when filled. At least one handle has three layers of polymeric material for improved strength. The bag includes a tamper-indicating closure and has a high friction coefficient to prevent sliding of stacked bags.
