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 a handle having 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.
