The quality of food packaging bags in the soft packaging industry, especially the hygienic quality, is directly related to the safety of the packaged food. Therefore, we should ensure that the raw materials and additives used meet the quality requirements of the management system.
Only by improving the industry and national standards of packaging film bags and strictly implementing them, strengthening inspection and supervision of food packaging bags, preventing unqualified food packaging from entering the market, and strengthening management, can the healthy development of the soft packaging industry be guaranteed.
The inspection items of food packaging bags are mainly divided into the following categories: no defects such as blisters, perforations, water marks, rebars, poor plasticization, fish eye stiffness, etc. which hinder the use of food packaging bags. 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.
