A food packaging bag is a packaging design, and is convenient for keeping food fresh and storing in life, so that a product packaging bag is produced. The food packaging bag refers to a film container which is directly contacted with food and is used for containing and protecting the food. Food packaging bags can be divided into, according to their application ranges: common food packaging bags, vacuum food packaging bags, aerated food packaging bags, poached food packaging bags, steamed food packaging bags and functional food packaging bags.
The quality, especially the sanitary quality, of food packaging bags in the flexible packaging industry is directly related to the safety of packaged food, so that the used raw materials and additives are ensured to meet the management system of quality requirements.
The inspection items of the food packaging single-film bag are mainly divided into the following categories: the appearance of the fish-eye ointment can not have defects such as bubbles, perforation, water marks, muscle violence, poor plasticization, fish-eye stiff blocks and the like which can hinder the use; the deviation of specification, width, length and thickness should be in the specified range; the physical and mechanical properties comprise tensile strength and elongation at break, which reflect the capability of the product to stretch along with the product in the using process, and if the product is unqualified, the food packaging bag is easy to crack and damage in the using process.
The current wrapping bag that can carry out the secondary and seal is usually the joint sealed, and this kind of secondary sealed wrapping bag has gluey to seal before unsealing and joint sealed cooperation forms double-deck sealed, and it is sealed only the joint after opening the bag, the joint is sealed repeatedly usable many times, take after the food, with its joint together again, still can have sealed effect, but this kind of mode needs to counterpoint the joint, but the joint often has some normal joint of failing, lead to leaking gas, make the save time of inside food shorten, very easily receive the condition of pollution.
