  • 2023 Flat food vacuum bag VS co-extrusion vacuum seal bag
Designers engaged in food packaging know that there are two types of vacuum packaging bags widely used in the market:
  • Comparison of two food vacuum bags: 1. Flat vacuum bags; 2. Textured vacuum seal bags. Many new packaging designers still don’t know what is the difference between a flat vacuum bag and a textured vacuum seal bag? Teampack is planning a series of vacuum packaging food bags for a brand recently.
  • Let’s see 6 major differences as follows:

  1. The material difference: the food-grade flat vacuum bag with nylon/PE, PET/RCPP, PA/RCPP, PET/PA, and other composite materials; and the material of the seven-layer co-extruded vacuum seal bag is PA+PE.
Flat vacuum bags
Textured vacuum seal bags

2. The difference in appearance: the front and back sides of the food-grade flat vacuum bag are smooth and transparent; while the textured vacuum seal bag with two side: smooth and transparent, textured.

3. Visual comparison: flat vacuum bag supports various table printing, but a textured vacuum seal bag cannot. If you need to carry out product image packaging design, Then you need to add an outer packaging bag for packaging image design and printing.

4. Difference in performance: the textured vacuum seal bag has one side textured, which can form multiple micro-channels so that there is no dead angle in vacuuming. so the vacuuming effect and flatness are better than flat vacuum bags.

5. The difference in safety: the textured vacuum seal bag with no compounding, no printing, and no ink pollution. especially in the high-temperature cooking process, there will be no glue precipitation, causing secondary pollution, So it is safer than flat vacuum bags.

6. Price difference: usually， the price of 7 layer co-extruded vacuum seal bags is 30% higher than that of flat vacuum bags.
