The invention discloses an environment-friendly bag. The environment-friendly bag comprises a front bag wall, a rear bag wall and a bottom bag wall, and is characterized in that the front bag wall, the rear bag wall and the bottom bag wall of the bag body are formed by folding a piece of cloth in the middle; a front crease, a middle crease and a rear crease are remained between the front bag wall and the rear bag wall by folding; the bag wall between the front crease and the rear crease forms the bottom bag wall; and the edges on the two sides of the front bag wall, the rear bag wall and the bottom bag wall form sealed edges on the two sides of the bag body at one time by hot-pressing equipment. The environment-friendly bag has the advantages of novel structure and style, large bearing force of the bag body, firmness, no need of manual cutting before hot pressing and simple process and capability of being produced in an automatic flow line production way.
Description
technical field [0001] The invention relates to the technical field of environmental protection bags, in particular to an environmental protection bag that does not need manual cutting before heat sealing, can be produced by automatic flow operation, and has a simple process. Background technique [0002] In daily life, shopping bags etc. are often used; and traditional shopping bags are generally made of plastic film, but the shopping bags of plastic film have the following disadvantages: (1) the bag made of plastic film can only Can be used once; (2) After the bag made of plastic film is discarded, it will form white garbage, which is not easy to decompose and cause environmental pollution. [0003] In order to solve the above-mentioned shortcomings of traditional plastic film plastic bags, some people began to use non-woven fabrics instead of film plastic bags on the market to make environmentally friendly non-woven bags; the existing non-woven bags have the following str...
