Introduction to the technology of making paper bags

The paper bag should first be an extension of the corporate image and product advertising strategy. Therefore, the production of paper bags must be environmentally friendly, beautiful, delicate and durable. The structure is tight, and the handle does not come off. The "hot sol" is used to make a full-automatic bag making machine to stick all parts of the paper bag to form a tight structure. Therefore, the handle will never come off the bottom, which is different from the traditional paper bag after printing. Processing is to stick the bag body with "white glue", and then manually thread the rope and knot it as the handle, so there are often mistakes in taking off the bottom and loosening the handle. There are no creases on the surface of the paper bag, and the bonding is accurate and beautiful. The automatic bag making machine is used to make the portable paper bag, so there are no creases on the surface of the bag. In addition, the hot sol has a strong fixing force and dries quickly, so the bonding is accurate and beautiful. The traditional paper bag processing is to fold the sticker bag by hand, so the bag surface has a fold line, and the white glue is slow to dry and solidify. When the amount is too large, the glue will overflow and slide, so the bag shape is poor.

Upright cotton rope handle, no perforation and no rope knot, two pieces of heavy kraft paper are used to fix the cotton rope with hot melt, and then the kraft paper is fixed on the paper bag. No protruding knots. The handle of the traditional handmade paper bag is to punch the bag body first, then manually thread the nylon rope through the knot, and use the knot to jam the paper bag. rope hole. The overall structure is strengthened, and the packaging function is enhanced. The handle, kraft cardboard, paper bag, and bag bottom are integrally formed with hot melt, so the overall structure of the paper bag is strengthened, and it can withstand items over 5 kg. In traditional paper bags, the handle is made of nylon rope knots to hold the bag body, and the top sheet of the paper bag is not glued to the bag body, so the material bearing capacity is weak. Excellent quality and fast delivery. The automatic bag making operation is adopted, so the quality is excellent and stable, especially without the need to manually thread the large knot to make the handle, which shortens the production process of the feature film and the delivery time is fast. The design specification and manufacturing principle of paper bag printing The top edge of the paper bag is folded inward by 60mm, which is used to strengthen the fixing force of the handle. The width of the bottom edge of the paper bag is 15mm to strengthen the material bearing capacity of the bottom of the bag (the edge width is reduced by 15mm). The sticking edge of the paper bag is always 30mm, and it must be on the right side to automatically stick the bag.

Square Bottom Paper Bag Machine

The finished paper bag should be marked with 2 lines on the paste side, 6 lines on the top edge, and 6 lines on the bottom edge, etc., so that the paper bag can be formed correctly. The size of the portable paper bag should be in line with the number of sheets in order to facilitate economic benefits. The silk direction of the paper should be parallel to the "height" of the paper bag to facilitate the folding of the paper.
