Analysis of the damage reason of vacuum packing bag

- Vacuum Pouch

For many customers in the use of vacuum packaging bags, there will be a broken bag leakage phenomenon, resulting in product leakage.So what's the reason for this? How can we control and prevent it? The following is the analysis of the reasons for the broken nylon vacuum packaging bags:

 

1. Function of raw materials

Poor endurance -- the use of packaging materials are brittleness and poor tolerance.It`s easy to make the product packaging in the fall or the impact of external forces, so that break the bag.

It can be verified by monitoring the explosion pressure, anti-drop function, anti-pressure function, tensile strength and elongation at break, and anti-pendulum impact.

  1. Low compound fastness -- plastic packaging is mostly compound film, which is easy to present the phenomenon of compound film lamination due to low compound fastness, resulting in the deterioration of the tolerance of all compound film, resulting in the nylon vacuum bag breaking.This can be verified by monitoring the peel strength test.

Precautions when purchasing:

First, it is necessary to pay attention to the monitoring of various functional indexes of vacuum packaging bags, such as explosion pressure, anti-drop function, anti-pressure function, thermal sealing strength, thermal adhesion strength, tensile strength and elongation at break, anti-pendulum impact, peeling strength, etc.

Second, to improve the parameters of the heat sealing machine, choose packaging materials with excellent flexibility.

Vacuum bag is also called decompression packaging, which is to take out all the air in the packaging container and seal it, and maintain the bag in a highly decompressed state. The lack of air is equivalent to the effect of low oxygen, so that microorganisms have no living conditions. It can reach the intention of fresh fruits and free from disease and rot.

Now the application of vacuum packaging in plastic bags, aluminum foil packaging, glassware packaging.

Packaging materials can be selected according to the variety of goods.

As fruits are fresh food, they are still in respiration, and high hypoxia will cause physiological diseases. Therefore, fewer fruits use vacuum packaging.
