Problems solved by technology

After the bag body bottom of the plastic bag is folded and sealed, the length of the bag body in the up and down direction will be reduced, resulting in less space for accommodating garbage inside the plastic bag. Therefore, the plastic bag will be filled quickly. Users need to change plastic bags frequently, which not only wastes resources, but also causes environmental problems

Abstract

A manufacturing method of packing bags comprises the following steps that a long material belt is manufactured to be in a hollow surrounding shape and is defined to form a first long side edge and a second long side edge; the material belt is hot melted so as to form two long sealing portions which are mutually separated, and each long sealing portion are connected between the first and the second long side edges; the material belt is folded so as to form three folding lines which are mutually separated between the first and the second long side edges, and extension directions of the folding lines are identical to that of the first and the second long side edges, so that the belt material is provided with a folded belt body which has four mutually folded sheets; a long stripping line which extends in the direction of the length direction of the long sealing portions is formed in the middle of each long sealing portion; and a separation stripping line positioned in the middle of the two long sealing portions are formed on the folded belt body of the material belt.

Description

Technical field [0001] The invention relates to a packaging bag and a manufacturing method and manufacturing equipment thereof, in particular to a continuous reel packaging bag and a manufacturing method and manufacturing equipment thereof. Background technique [0002] In the manufacturing process of the existing reel-type continuous plastic bag, each processing section is a necessary processing step for forming a plastic bag on the plastic material belt every time the plastic material belt is processed. When a predetermined number of plastic bags are to be formed on a plastic strip, each processing section has to process the plastic strip the same number of times as the aforementioned predetermined number to form a predetermined number of plastic bags on the plastic strip. , The manufacturing efficiency of existing manufacturing equipment is poor. [0003] In addition, in the manufacture of existing plastic bags, the bottom end of the bag body is usually folded first, and then t...
