Abstract

The invention is a papery environmental protection bag, composed of front piece and back piece, their bottoms and two sides mutually button and then are linked by heat rolling or sticking, their tops have unconnected bag mouths, there are two carrying pieces on two sides of the bag mouth, respectively, the tops of the carrying pieces in the opposite position of the front and back pieces mutually button and are linked by heat rolling or sticking to form a carrier, and the bag mouth is linked with the carrier in an arc transition, and its character is that there is a component force tearproof strip. The front and back pieces both have bearing component force impresses. It has characters of prevent the bag mouth from being torn, no pollution and environmental protection, able to be used as packaging bag in supermarket and marketplace to replace the plastic bag.

Description

technical field [0001] The invention relates to a daily necessities, in particular to a paper environmental protection packaging bag which is made of paper material and is beneficial to environmental protection.
