        Paper bags are roughly divided into two categories: ordinary packaging bags and delicate shopping bags. Ordinary packaging bags are produced by a rotary printing bag making machine. It has the advantages of fast production efficiency, and the disadvantage is that the paper bag is rough and inexhaustible, so most of these paper bags are used for general commodity packaging. As for the exquisite shopping bags, they are printed in color on a sheet of paper, pp-framed or bronzed, and then produced by manual or semi-automatic machines by a bag-making factory, and finally tied with artificial ropes as handles, to complete the paper bag lifting. Its advantages: paper bags can be made in any situation, the disadvantage is the slow production speed. Most of these advanced shopping bags are used for noble product packaging, or as gift bags, or as advertising bags for various product activities.
        Shopping bags should first be an extension of corporate image and product advertising strategies, so making shopping bags must be environmentally friendly, beautiful, durable. The structure is compact, and the hot-melt adhesive is used to make the bag loose. The automatic bag-making machine is used to bond all parts of the shopping bag to form a compact structure. After processing, the "white glue" is used to paste the bag body, and then the artificial rope is used as a handle. Therefore, there are often mistakes in removing the loose handle. The paper bag surface has no creases, and the adhesion is accurate and beautiful. The automatic bag making machine is used to make shopping bags. Therefore, the bag surface has no creases, and the hot-melt adhesive has strong fixing force and dries quickly, so the adhesion is accurate and beautiful. The traditional paper bag processing is to fold the sticker bag by hand, so the bag surface has fold lines, and the white glue dries slowly. When the amount is too large, the glue will overflow and slide, so the bag shape is poor.
        Shopping bag design specifications Manufacturing principles The top edge of the paper bag is uniformly folded within 60mm to strengthen the grip of the handle. The width of the bottom edge of the paper bag is 15mm. To strengthen the bearing capacity of the bottom of the bag (the width of the side is reduced by 15mm), the edge of the paper bag is uniformly 30mm. The finished shopping bag should be marked with 2 folded edges, 6 on the top edge, and 6 on the bottom edge, so that the paper bag can be correctly formed. The size of the shopping bag should be in accordance with the number of papers, in order to facilitate economic benefits. The paper direction should be parallel to the "height" of the paper bag to facilitate the folding of the paper.

        Applicable paper: Kraft paper / kraft paper is tough and can be divided into: white kraft paper, yellow kraft paper, two-color kraft paper and other papers: on paper, it can also be: pure kraft and copper plate kraft, basically from 80 to 120 pounds Kraft paper is suitable for making all kinds of shopping bags. Coated paper / coated paper is suitable for high-quality color printing, so art shopping bags are usually made with coated paper of 120 to 150 pounds. Due to the low toughness of coated paper, pp film is generally used to strengthen its toughness. Art paper / art paper is a vague term used to describe processed and dyed paper. Generally, art paper is tougher than coated paper, and the paper is diverse. Many art papers of 100 to 150 pounds are quite suitable for making shopping bags, but the paper cost is higher. Special paper / For example: Nanya Synthetic Paper, 3M Tvik Paper, pp imitation kraft paper, etc.
