How many factors should companies consider when choosing vacuum packaging bags?

Plastic vacuum bags can be divided into two categories based on the number of layers of plastic film: single film and composite film. They can be further divided into one layer, two layers, three layers, four layers, and even more than 10 layers. Vacuum bags have more applications in transportation packaging and sales packaging. So how many factors should companies consider when choosing vacuum packaging bags?

1、 The puncture resistance strength of vacuum packaging bags.

Whether it is transportation packaging or sales packaging, one of the important functions of packaging bags is to protect food. If most of them are punctured, it will not have a protective effect. So we need to understand whether our product has sharp hard substances and what level of puncture ability it has. The common method is to ask the packaging manufacturer to provide samples, vacuum package and test them themselves, and then use techniques such as throwing, throwing, and pressing to see if there is any bag breakage.

2、 The usage environment of vacuum packaging bags.

Including processing environment, storage environment, transportation environment, different environmental requirements for selecting different plastic films and printing processes. For example, ready to eat salted duck feet, after vacuum packaging, require different materials for the packaging bag when using high temperature and boiled water. Plastic film is required to withstand high temperatures of 121 ℃ or above, while water boiling requires 100 ℃, and it is insoluble in high temperature environments with strong water resistance.

3、 Other requirements.

The use of vacuum bags for food is to extend the shelf life and effectively preserve its color, aroma, and taste. In addition to the need for puncture resistance, there are many other performance requirements. Salt baked chicken legs and chicken wings both contain oil and produce aromatic molecules. Vacuum packaging bags should also have oil resistance and fragrance retention.
