            Color direct contact with the food plastic shopping bag should be the true colors. Other plastic shopping bag ontology is generally true or white, or other colors. Appearance does not allow the use of air bubbles, perforation, plastic bad, fish eye stiffness and other defects. Bag film should be uniform, flat, no crease. Printing quality printing plastic shopping bags should be uniform ink, pattern, text clear, complete, overprinter accurate, overprinter error should be less than 1mm, printing stripping rate is less than 20%.Plastic Shopping Bags

             Physical and mechanical properties should conform to table 3 and table 4 requirements.
