Process of Paper Bags

Paper bags production processes and technique

　Paper bags are widely used in clothing, food, shoes, gifts, alcohol, drugs and other areas of packaging. At present, we can use them a lot of paper divided into two types of mobile. 

One is popular with ordinary paper bag packaging. Most of these paper bags with rotary printing, automated production lines to complete the bag, making the material more choice of kraft paper bags, paper size and pattern relatively inflexible, the advantage of high efficiency, suitable for mass production. 

The other is beautiful, exquisite packaging, shopping bags. Generally use this type of paper sheet-fed printing, rely on manual or semi-automatic production of kraft paper, coated paper, cardboard, paper bags are often selected as the processing of materials. Most of them have high-end products for the packaging, gift bag or bags of various business activities of advertising. Features of any shape, size paper bag can be produced, but the process is relatively complex, low production efficiency. This paper specifically for this type of paper to discuss the hand bag in the production process. 

The use of functional or design requirements, the mobile manufacturing process used in paper bag with a certain complexity, but the basic process can be summarized as follows: 

Here we expand on this flow chart of the production process and bag some technology issues. 

1)design 

Paper bag paper bag design is the key link in the production process. Most paper products and corporate image is an extension of advertising strategies, the choice of materials, decoration techniques and forms of expression are associated with the use of paper bags and effectiveness are inextricably linked. Kraft's toughness, high strength, rough surface. Jam good stiffness but the toughness is poor, as the surface of coated paper generally required. Coated paper has a certain toughness, printing, rich colors, but the stiffness worse than cardboard. More emphasis on...
