Application and production standards for portable paper bags

Paste paper bags are an ancient handicraft industry. However, in post-press processing, most printers know a little about bookbinding or Carton rolling, but the production process of portable paper bags may not be well understood. Hand-held paper bags are roughly divided into two categories: ordinary packaging bags and exquisite shopping bags. Ordinary packaging bags are produced by a rotary printing bag making machine and consistent production operations. Its advantages are fast production efficiency, the disadvantage is that the paper bags are rough and not delicate, so most of these paper bags are used in general ordinary goods packaging. As for the exquisite shopping bags, they are printed on a single sheet of paper, after PP light or gold stamping, and then produced by manual or semi-automatic machines by the bag factory, and finally tied with a manual string to complete the bag . Its advantages are: paper bags can be made in any situation, the disadvantage is that the production speed is slow. These high-end shopping bags are mostly used for noble commodity packaging, or as gift bags, or as advertising bags for various commercial activities. Finally, these exquisite and beautiful paper bags have become the convenience for ladies to go shopping. Shopping Bag.

Characteristics of shopping bags

Environmentally friendly, beautiful, durable

Shopping bags should first be an extension of corporate image and product advertising strategy, so making shopping bags must pay attention to environmental protection, beauty, exquisite and durable. The structure is compact, and the loose handle does not take off the bottom. The "hot melt" uses an automatic bag making machine to glue the various parts of the shopping bag to form a compact structure, so that it will never take off the bottom and take off the handle. The processing is to stick the bag body with "white glue", and then use the artificial string to tie the knot as the handle, so there are often mistakes of loosening the bottom. The Paper Bag surface has no creases, and the bonding is accurate and beautiful. The shopping bag is made by the automatic bag making machine. Therefore, the bag surface has no creases, and the hot sol has strong fixing power and fast drying, so the bonding is accurate and beautiful. The traditional paper bag processing is to manually fold the sticker bag, so the bag surface has a fold line, and the white glue dries slowly. When the amount is too large, the glue will overflow and slide, so the bag shape is poor.

Upright cotton rope handle, no holes and no knots

Use two pieces of heavy kraft paper to fix the cotton rope with hot melt, and then fix the kraft paper to the paper bag. The handle of the shopping bag is "upright" and there is no need to punch holes and no protruding knots. The handle of the traditional handmade paper bag is to punch the bag body first, and then manually tie the nylon string through the knot, and use the knot to catch the paper bag, so the handle knot is easy to loosen when carrying the object, or the paper bag is broken Rope hole. The overall structure is strengthened, and the packaging function is enhanced. The handle, kraft paper, paper bag, and bottom of the bag are integrally formed with hot melt, so the overall structure of the shopping bag is strengthened and can withstand items over 5 kg. In the traditionally made paper bags, the handles are made of nylon rope knots to clamp the bag body, and the top sheet of the paper bag is not bonded to the bag body, so the material carrying capacity is weak.

The high quality and fast delivery time adopts the automatic and consistent bag-making operation, so the quality is excellent and stable, especially without the manual threading and knotting, which is the shortening of the feature film production process and the rapid delivery time.

Design and manufacturing principles of shopping bags The top edge of the paper bag is folded by 60mm uniformly to strengthen the grip 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 (side width minus 15mm).

The paper bag paste edge is always 30mm, and it must be on the right side to automatically paste the bag.

The finished shopping bag should be set with 2 fold edges, 6 top edges, 6 bottom edges and other folding bag marks to facilitate the correct formation of the paper bag. The size of the shopping bag should be consistent with the opening number of the paper to benefit economic benefits. The thread direction of the paper 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 distinguished in color: white kraft paper, yellow kraft paper, two-color kraft paper, etc .: on paper, it can be divided into: pure kraft and copper kraft, basically from 80 to 120 pounds of kraft paper , Are 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 with 120-150 pounds of coated paper. Due to the low toughness of coated paper, PP film is generally used to reinforce its toughness. Art paper / art paper is a vague term used to describe paper that has been processed and dyed. Generally, art paper is tougher than art paper, and the paper quality is diverse. Many 100-150 pound art papers are quite suitable for making shopping bags, but the paper cost is higher. Special paper / for example: South Asian synthetic paper, 3M Taiweik paper, pp imitation kraft paper ... etc.
