Our food packaging manufacturers must strictly require the quality of products and check them in production. Every production link needs professional personnel to supervise and control them strictly. When purchasing, the purchaser should also inspect each batch of products strictly and carefully to prevent huge losses caused by a small omission.

The quality of food packaging bags, especially the hygienic quality, is directly related to the food safety in the plastic flexible packaging industry. Therefore, it is necessary to ensure that the raw materials and additives meet the quality requirements of the management system. Only by improving the industry and national standards of packaging bags and strictly implementing them, strengthening the inspection and supervision of food packaging, preventing unqualified food packaging from entering the market and strengthening management, can the healthy development of the soft packaging industry be guaranteed.

No defects such as blisters, perforations, water marks, rebars, poor plasticization, fish eye stiffness, etc. which hinder the use of the product shall be allowed in the appearance. The deviation of specification, width, length and thickness should be within the prescribed range.

Physical and mechanical properties include tensile strength and elongation at break. It reflects the ability of the product to be stretched during use. If this is not qualified, food packaging bags are prone to break and damage during use.

Food packaging bags with unqualified quality are very harmful to both food packaging manufacturers and ordinary consumers. In order to be responsible for the vast number of consumers, and also for the development and progress of enterprises themselves, food packaging manufacturers should strictly control the quality of food packaging bags in the production process and improve the quality of food packaging bags.

It can be predicted that in the next few years in China, the packaging industry will develop rapidly, among which petroleum and other chemical products are indispensable materials in the production of packaging bags. In the future, the use of plastic products will become more and more frequent. It will gradually reduce people's use of glass products. Sometimes plastic products will replace metal products.

Further development of aseptic packaging will reduce the need for refrigeration equipment. Some consumers feel that metal canned food is a high-grade product, and aseptic packaging is mostly cartons and low-cost products. In fact, this is a misunderstanding. Packaging should take twice the effort. As long as food can be well preserved, the cheaper it is, the better it is.
