For citizens, whether it is customized plastic bags or daily use, they are all finished plastic bags. Many people may not understand how plastic bags are made. It can be said that the production of plastic bags is not an easy task, it seems simple but complicated.

For ordinary supermarket vest bags, it involves a series of steps such as design and typesetting, film blowing, printing plate, sealing and cutting, and packaging. Each step is chained, and any delay in any link will affect the production cycle and even the quality of plastic bags. For example, in vest bag printing, if there is a problem with the plate making, it needs to be returned to the plate making factory. It takes two or three days to go back and forth, and the time for loading and unloading the plate and adjusting the ink is not counted. Plastic bag printing is an extremely important step, which can be said to reflect the production level of plastic bag manufacturers. In the production process of plastic bags, copper plates and electric carvings, such as vest bags, are usually used. If the customer's order is small or the size of the plastic bag exceeds the machine printing range, the offset printing plate is generally used for screen printing. This method can also be well controlled in terms of cost, and in terms of quality, it is also very satisfactory from the customer's feedback, so this is currently a relatively common printing method.

Since the promulgation of the plastic restriction order, Qingdao's requirements for the material and thickness of plastic bags have increased a lot. Nowadays, supermarket t-shirt bags use brand-new materials, and the thickness is increased to more than 5 threads, which can produce more durable products, can avoid the phenomenon of discarding after one-time use, and effectively control the amount of plastic bags through repeated use.

Nowadays, the production requirements of plastic bags are getting higher and higher, and the competition is becoming more and more fierce. It not only requires high quality and low price, but also highlights product characteristics. The requirements for plastic bag material durability, printing design, printing quality and other aspects have also been greatly improved. Secondly, it is necessary to adapt to the needs of development and develop in the direction of environmental protection and pollution-free. For plastic bag manufacturers, this is both a challenge and an opportunity. The survival of the fittest is a natural law. Without their own advantages, it is difficult to gain a foothold in the market. Once this opportunity is seized, the prospects will be broad. This requires manufacturers to at least have standardized processes in management. Regardless of the size of the order, the needs of customers should be fully considered. Every plastic bag customization must be strictly controlled to achieve high efficiency and high quality.
