The cause of Vacuum Zipper Bag leak.vacuum zipper bags company

　　Nutbag manufacturer: Vacuum Zipper Bag Leakage

　　Vacuum Zipper Bag aims to ensure the cleanliness and extend the shelf life. However, after the food vacuum bag is leaked, the original intention of the vacuum packaging is completely deviated.

　　1. Food vacuum packaging design

　　If the net content or volume of the contents exceeds the tolerance range of the soft packaging materials used, during the transportation or sales circulation process, if it is slightly external effect, the bag will be broken and broken. Generally, it is used as a hot seal layer of a vacuum packaging bag. The thickness of the material is not thick. It should be less than 50m.

　　2. The quality of food vacuum packaging materials

　　The quality of the packaging material leads to the seal and cracking of the finished packaging packaging, which is generally concentrated in the following aspects, such as stretching and cracking force, stretching and cracking and elongation, puncture strength, pendulum resistance, stripping strength, etc. Whether the physical mechanical properties such as toughness, stunning resistance, and impact resistance meet the requirements of packaging, storage, stacking, and transportation.

　　The uniformity of the heat seal effect, such as the vacuum packaging of chicken feet is damaged, because when the chicken feet are cut, some broken bones are cut very sharply. When cooking chicken feet, the skin of the meat will shrink, so the bones will be Exposed, it is easy to pierce the bag during transportation.

　　Therefore, the puncture resistance of the packaging bag should be considered as the key point of the packaging material combination. The leakage and sealing strength tester can not only detect the broken force of the soft packaging bag, but also test the decay time of the packaging bag by setting the pressure. According to the test data design stack structure, further adjust the hot seal process parameters to improve the packaging effect. You can also analyze the problems of the packaging structure based on the damaged position of the soft packaging bag.
