According to the material, it can be divided into: white cardboard paper bag, white cardboard paper bag, copper cardboard paper bag, kraft paper bag and a small amount of special paper.
Paper bags are divided into four types according to the methods of edge wrapping, bottom wrapping and bottom sealing: slotted bottom bag, open corner bottom bag, valve seam bag and valve flat hexagonal bottom plastic bag.
According to the different handles and hole-digging methods: NKK (hole-piercing rope), NAK (hole-free rope, which can be divided into mouth-less folding type and standard mouth-folding type), DCK (cordless bag hole-digging handle) and BBK (no punch tongue).
According to different uses: including paper bags, envelopes, handbags, cement bags, feed bags, wax paper bags, fertilizer bags, composite paper bags, four-layer paper bags, medicine bags, clothing bags, food bags, shopping bags, gift bags and wine bags. According to different purposes, the design specifications, including the thickness of paper bags, have many requirements, which should be customized according to the actual situation, so as to achieve the goal of getting twice the result with half the effort and being economical and applicable, and provide more protection for saving materials, protecting the environment and capital investment of enterprises.
Other paper bags: including cement bags, feed bags, wax paper bags, fertilizer bags, laminating paper bags, four-layer paper bags, medicine bags, fine packaging paper bags, clothing paper bags, gift bags and food bags.
As we all know, paper is a recyclable resource. The raw materials for papermaking are mainly plant fibers. In addition to cellulose, hemicellulose and lignin, there are other components with less content, such as resin and ash. In addition, there are auxiliary ingredients such as sodium sulfate. Besides plant fiber, different fillers need to be added according to different paper materials. Commonly used plastic bags are made of polyethylene, and the raw material used is oil, which is already our scarce energy. In contrast, the raw materials of paper bags are trees, which are renewable resources. Because of its biodegradable and recyclable characteristics, it is naturally labeled as green. Not all paper bags are degradable. Some paper bags are covered with plastic film. If the film material is PVC, it will not only be harmful to human health, but also affect the normal decomposition of paper materials. In addition, the production of paper is mainly based on logs, and excessive production of paper bags leads to a large number of trees being cut down, which will also destroy the environment. The immaturity of papermaking technology makes a lot of waste water and waste gas produced in the production process. If the treatment equipment is backward, it will still pollute the environment if it is discharged without treatment or incomplete treatment.
Edit the design features of paper bags in this paragraph. The design of portable paper bags is different from the past. Selecting and pasting portable paper bags is a very old handicraft industry. But now in order to improve efficiency and save manpower and cost, machines are generally used for processing. Nowadays, paper bags are mainly divided into ordinary packaging bags and exquisite shopping bags. This is also the new portable paper bag of 20 1 1. So how are these two kinds of paper bags made? Hua Yang said.
Ordinary commercial paper bags are mainly produced by rotary printing paper bag machines. This method has high production efficiency, but the disadvantage is obvious, that is, the paper bag is rough and not delicate. Exquisite shopping bags are mostly made of single sheets of paper, then printed in color, polished by PP or bronzed. Finally, the paper bag factory will carry out manual or semi-automatic machine production [1], and usually use manual knotting as the handle, and then complete the production of paper bags. The advantage of this kind of shopping bag is that any shape of paper can be made into portable paper bags. However, this mode of production is inefficient. This kind of paper bag is mostly used to pack some valuables as gift bags. Or as an advertising bag in some commercial activities. Of course, exquisite and beautiful portable paper bags have also become convenient shopping bags for ladies to go out shopping.
Portable paper bags are the first choice for shopping bags now. At the same time, it is an extension of corporate image and commodity advertising. When making shopping bags, we should not only pay attention to the tight structure, but also pursue environmental protection, beauty, exquisiteness and durability.
If you are still worried about handbag design, it is better to refer to Huayang's handbag design products.
20 1 1 The new portable paper bag mainly tends to be environmentally friendly, durable and beautiful. The manufacturing method has also been improved and improved.
