Recently, many customers have inquired about textured vacuum bags, and the unit price of textured vacuum bags is higher than that of regular vacuum bags. Why do many people still use textured vacuum bags? What is the difference between textured vacuum bags and regular vacuum bags?

1、 Material and process of textured vacuum bags and general vacuum bags

Firstly, the textured vacuum bag, which has one side colorless and transparent, and the other side textured, is made by co extrusion of PA and PE seven layers. The material cost is relatively high, and the natural price is relatively expensive. A typical vacuum bag is CPP or PA composite PE. In terms of thickness, the former has a single layer of 9 threads or more, while the latter is slightly thinner.

2、 The advantages of textured vacuum bags

1. Single sided texture, forming many microchannels, making vacuum extraction without dead corners.

2.7 layer co extrusion without adhesive bonding. Although many manufacturers claim that glue is non-toxic, many are impatient and eager for quick success. Only by cutting corners on raw materials can the quality of glue be difficult to ensure. During the cooking process, the glue in the vacuum bag is usually boiled out, and it is unknown whether it is toxic. So relatively speaking, textured bags are more hygienic.

3. The textured bag is not printed and will not be contaminated with ink or chemical solvents.

3、 Texture vacuum bags will surpass general vacuum bags in the future

The market for textured vacuum bags is not very large now, but as people's awareness of food hygiene gradually increases and supervision of food and its packaging becomes increasingly strict, textured vacuum bags will definitely be popular!

In the future, vacuum packaging that directly touches food, especially steaming bags, should mainly use unprinted single-layer co extruded bags. If patterns are needed, a beautifully printed bag should be covered. The outer bag can be a series of exquisite packaging bags such as upright bags, octagonal sealed bags, etc.
