How are paper bags produced?
Paper bags are widely used in commodity packaging in the fields of clothing, food, footwear, gifts, tobacco and alcohol. Due to the difference in function and design, the production process of paper bags has a certain complexity, but the basic production process and process can be summarized as follows.
The design of paper bags is an important part of the entire production process. For production and quality control,it is essential to design a complete and clear set of operational engineering drawings before the production of the paper bag.
The printing process of paper bags is different from general printing.It should pay attention to the printing position to ensure that the size of the paper bag on the glue and the bottom when printing. If the printing needs to be coated process must also pay attention to the control of the thickness of the ink layer, minimize the use of spray powder.
Coating refers to Lamination refers to the surface of the paper bag covered with a layer of 0.012-0.020mm thick transparent plastic film, which is generally divided into two processes: pre-coating and instant coating. The coating can increase the concentration of color and has the functions of waterproof and stain avoidance. When coating paper bags, you also need to pay attention to selecting the appropriate laminating glue and controlling the speed and amount of lamination
4.Tube forming processing
Tube forming, also known as rolling marks, is an important process in the production process of paper bags. The quality of the tube will directly affect the quality of paper bag forming and the efficiency of gluing process. When forming a tube, it is necessary to pay attention to selecting the correct template, controlling the strength and considering the toughness of the paper.
Gluing is the last step in the production of paper bags. You need to select suitable glue according to the material of the paper bag. In the process of gluing, it is also necessary to pay attention to the amount of glue to avoid too much glue overflowing or too little glue paper bags cannot be glued. If the production of paper bags with handles, you also need to pay attention to the paper bag to avoid the handle before gluing.
Through the above process introduction, we can simply know the production process of paper bags. Each process is interlinked to produce a complete paper bag.
The last ,it is able to leave a deep impression on customers. Currently, paper bags are diversified in terms of design, color and aesthetics. Exquisite and luxurious paper bags will leave a deep impression on customers. On the other hand, when printing paper bags, the company's logo, information and address can be printed on the paper bags ingeniously. This is convenient for customers to contact directly when they buy again, also helps to promote the brand and expand its popularity.MORE +
Paper bags are now widely used as they can be recycled and are not harmful to the environment even if they are discarded in the natural environment. At the same time, paper bags can play a very good role in publicity. Many companies will deliberately print their own brand names or logos when customizing paper bags , thereby increasing the brand awareness .It is because of these characteristics of the paper bag it can slowly occupy the market. Paper bag packaging applications are very wide, mainly focused on clothing, food, medicine and cosmetic fields..MORE +
