What Causes Your Food Vacuum Packaging Bag Broke?
Vacuum packaging bagis often seen in everyday life. The main function of the vacuum packaging bag is to remove oxygen, which is beneficial to prevent food spoilage. And vacuum deoxidation is another important function to prevent oxidation of vacuum packaging.
Mainly because of two reasons of the breakage of food vacuum packaging: defective packaging design or vacuum packaging materials:
1. The design of food vacuum packaging bags.
For example, if the net content or volume of the content exceeds the tolerance range of the flexible packaging material used, a slight external force will cause problems such as bag breakage and cracking. Generally, the heat-sealing layer of the vacuum packaging bag should not be less than 50 μm thick.
2. The material of the vacuum food bags.
The quality problems of the packaging materials have caused sealing cracks in the finished packaging, including the following two points:
Whether the physical and mechanical properties of the food vacuum bag—such as the breaking force and tensile elongation, puncture resistance, pendulum impact resistance, peel strength, and other physical and mechanical properties meet the requirements of the packaging and transportation process.
The sealability of food packaging and such as a burst pressure test can determine the location of broken bags and 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 location of the heat seal failure and the uniformity of the heat seal effect.
For example, the breakage of the vacuum packaging of chicken feet is caused by the broken bones of some broken claws when the chicken feet are cut. In addition, the skin shrinks when boiled, so the bones are exposed, which is easy during transportation. Pierce the bag. Therefore, the puncture resistance of the packaging bag should be considered as the focus of the packaging material combination.
