Portable paper bag printing application and production standard

Paste portable paper bag is an ancient handicraft industry. However, in post press processing, most printers know a little about bookcase binding or carton pasting, but they may not know much about the production process of portable paper bags. Portable paper bags can be roughly divided into two categories: ordinary packaging bags and exquisite shopping bags. Ordinary packaging bags are always produced by the rotary printing bag making machine. Its advantage is fast production efficiency, but its disadvantage is that the paper bag is rough and not delicate, so this kind of paper bag is mostly used in the packaging of general commodities. As for exquisite shopping bags, they are printed in color on sheet fed paper, mounted or bronzed in PP, and then produced by the bag factory with manual and semi-automatic machines, and then tied with artificial ropes as handles to complete the paper bag. Its advantage is that paper bags can be made in any situation, but its disadvantage is that the production speed is slow. Most of these shopping bags are used for noble commodity packaging, or as gift bags, or as advertising bags for various business activities. Later, these exquisite and beautiful paper bags have become handy shopping bags for ladies to go shopping. Shopping bags should have the characteristics of

environmental protection, beauty, refinement and durability

shopping bags should first be an extension of corporate image and commodity advertising strategy, so when making shopping bags, we must pay attention to environmental protection, beauty, refinement and durability. It has a tight structure and does not take off the bottom and loosen the handle. It uses hot-melt glue to stick all parts of the shopping bag with a full-automatic bag making machine to form a tight structure, so it will never take off the bottom and loosen the handle. Unlike the traditional post press processing of portable paper bags, it uses white glue to stick the bag body, and then uses manual threading and knotting as the handle, so there are often mistakes in taking off the bottom and loosen the handle. The paper bag surface has no creases, and the bonding is accurate and beautiful. The shopping bag is made by the full-automatic bag making machine, so the bag surface has no creases. In addition, the hot-melt adhesive has strong adhesion and rapid drying, so the bonding is accurate and beautiful. The traditional paper bag processing is to fold and paste the paper bag by hand, so there are creases on the bag surface, and the white glue dries slowly. When it is too much, it will overflow and slide, so the bag shape is poor

upright cotton rope handle, non perforated and cordless knot

fix the cotton rope with two pieces of heavy kraft paper with hot-melt glue, and then fix the kraft paper on the paper bag. The handle of the shopping bag is upright and does not need to be perforated, nor does it have a protruding knot. The traditional handmade paper bag lifting handle is to punch holes in the bag body first, and then manually thread the nylon rope through the knot, and use the knot to clamp the paper bag, so the knot is easy to loosen when lifting objects, or pull the rope hole of the paper bag. The overall structure is strengthened, and the packaging function is enhanced. The handle, kraft board, paper bag and bag bottom are integrated with thermosol, so the overall structure of the shopping bag is strengthened, and it can withstand items of more than 5 kg. In the traditional paper bag, the handle uses the nylon knot head to clamp the bag body, and the top piece of the paper bag is not bonded to the bag body, so the material carrying capacity is weak

excellent quality and fast delivery. The automatic bag making operation is adopted consistently, so the quality is excellent and stable. In particular, there is no need to manually thread a large knot as a handle, which is the shortening of the feature film production process and the rapid delivery

the design specification and manufacturing principle of shopping bags. The top edge of the paper bag is folded inward by 60mm to strengthen the grip. The width of the bottom edge of the paper bag is 15mm to strengthen the material carrying capacity of the bag bottom (the edge width is reduced by 15mm)

the pasting edge of the paper bag is 30mm, and it must be on the right to paste the bag automatically

when the shopping bag is finished, it should be set with 2 pasting edges and 6 top edges. There are two collet lanes and 6 bottom edges on the installation, so as to facilitate the correct molding of the paper bag. The size of shopping bags should be in line with the number of paper to benefit economic benefits. The paper thread 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 the color can be divided into: white kraft paper, yellow kraft paper, two-color kraft paper and other paper types: in paper, it can be divided into: pure Kraft and coated kraft, basically from 80 to 120 pounds of kraft paper, which 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 often made of 120 ~ 150 pounds of coated paper. Due to the low toughness of coated paper, PP film glazing 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 stronger than coated paper, and the paper is diversified. Many 100 ~ 150 pound art paper are quite suitable for making shopping bags, but the paper cost is high. Special paper/for example: South Asia synthetic paper, 3M Tyvek paper, PP imitation kraft paper, etc. 2. Good heat resistance
