Solution for damage to vacuum plastic packaging
Plastic packaging bags are damaged during production, transportation and storage. It is a common quality problem for enterprises. Today, Jiuzhi Plastics Co., Ltd. conducts a simple analysis of vacuum food packaging:
Reasons for damage to vacuum food packaging
1. Food vacuum packaging design. If the net content or volume of the content exceeds the tolerance of the flexible packaging material used, during the transportation or sales process, if the external force is slightly affected, the problem of bag breaking and cracking may occur. Generally, as a heat sealing layer for vacuum packaging bags, the material thickness must not be less than 50 μm thick.
2. The quality of food vacuum packaging materials. The quality problem of the packaging material causes the sealing and cracking of the finished packaging, which is generally concentrated in the following aspects:
1 The physical and mechanical properties of food packaging - such as tensile strength and elongation at break, puncture resistance, pendulum impact resistance, peel strength, etc., can comprehensively determine the toughness, puncture resistance, impact resistance, etc. of the packaging bag. Whether the physical and mechanical properties meet the requirements of packaging, storage stacking and transportation processes. (related to the contents, the size of the bag, the transportation route and the packaging form)
2 The tightness of the food packaging - such as the burst pressure test, can determine the location of the broken bag and the weak mechanical strength. For example, the heat seal strength test can determine whether the heat seal strength meets the requirements of the food content, and determine the heat seal poor portion and the uniformity of the heat seal effect. For example, the chicken claw vacuum packaging is damaged because the chicken claws are cut, some of the broken bones are sharply cut, and when the boil is boiled, the skin shrinks, so the bones are exposed and easy to transport. Puncture the bag. Therefore, the puncture resistance of the package should be considered as a key consideration in the packaging material combination.
Through the leak and seal strength tester, not only can the maximum breaking force of the flexible packaging bag be detected, but also the breaking time of the packaging bag can be tested by setting the applied pressure. The stacking structure can be designed according to the test data, and the parameters of the heat sealing process can be further adjusted. Improve the packaging effect, or analyze the problems in the packaging structure according to the location of the flexible packaging bag.
