Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] A paper environmental protection bag, which is composed of a front pocket piece 1 and a back pocket piece 2, the shape of the back pocket piece 2 is the same as that of the front pocket piece 1, and both adopt the shape of a "vest", see figure 1 shown. The paper of the front pocket 1 and the back pocket 2 can be single-sided or double-sided PE coated long-fiber paper, white cardboard, tendon cardboard or fibrous backing paper. The width of the back pocket sheet 2 can be slightly smaller than the front pocket sheet 1, but its length should be consistent with the front pocket sheet 1. The bottom and both sides of the front pocket sheet 1 and the back pocket sheet 2 are fastened to each other and then connected by hot rolling or bonding, and the connected sheets on both sides form a folded edge of the inner volume. figure 1 The outer side of the m...

Abstract

A paper environmental protection bag, which is composed of a front pocket and a back pocket. The bottom and two sides of the front pocket and the back pocket are fastened to each other and then hot rolled or bonded. The front pocket and the back pocket are There is a disconnected pocket on the upper part of the pocket, and there is a handle on both sides of the pocket. The upper parts of the handles on the opposite positions on the front pocket and the back pocket are also buckled together and connected by hot rolling or bonding. A handle is formed, and the mouth of the bag and the handle are connected in a circular arc shape. It is characterized in that a force component tear-proof strip is provided on the mouth of the bag and the handle. The surface of the front pocket sheet and the back pocket sheet has load-bearing component indentations. It has the advantages of preventing tearing of the bag mouth and longitudinal bag breaking, green and environmental protection, and can be used as packaging bags in supermarkets and shopping malls, replacing plastic bags, and has great market prospects.

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.
