What is the difference between textured vacuum bags and ordinary vacuum bags?
Release time:2019-11-16
Recently, many customers have inquired about embossed vacuum bags. The unit price of embossed vacuum bags is higher than that of ordinary vacuum bags. Why do many people still use embossed vacuum bags? What is the difference between an embossed vacuum bag and a regular vacuum bag? Below, Shunxingyuan Packaging, a professional flexible packaging manufacturer, will explain.
I, Embossed Vacuum Bag and the material process of ordinary vacuum bags
First, the embossed vacuum bag, which is colorless and transparent on one side and embossed on the other, is made of PA and PE by seven-layer co-extrusion. The material cost is higher, so the price is naturally more expensive. Ordinary vacuum bags are made of CPP or PA composite PE. In terms of thickness, the former is single-layer 9 mil or more, while the latter is slightly thinner.
II, Embossed Of vacuum bags Advantages
1. Single-sided embossed texture forms many micro-channels, allowing for vacuuming without dead corners.
2. 7-layer co-extrusion, no glue lamination. Although many manufacturers claim their glue is non-toxic, many are impetuous and eager for quick success, cutting corners only on raw materials, making it difficult to guarantee the quality of the glue. During the cooking process, the glue in ordinary vacuum bags may leach out, and whether it is toxic is unknown. Therefore, relatively speaking, embossed bags are more hygienic.
3. Embossed bags have no printing, so there is no pollution from ink and chemical solvents.
III, Embossed Vacuum Bag Will surpass ordinary in the future vacuum bags
The market for embossed vacuum bags is not very large at present, but as people's awareness of food hygiene gradually increases and the regulation of food and its packaging becomes stricter, embossed vacuum bags will surely become popular!
Shunxingyuan Packaging believes that in the future, vacuum packaging that directly contacts food, especially retort pouches, should mainly use unprinted single-layer co-extruded bags. If patterns are needed, a beautifully printed bag should be used as an outer layer. The outer bag can be a stand-up pouch, an eight-side sealed pouch, or a series of other exquisite packaging bags.
