Chapter 5. What Is The Difference Between Non woven Cooler Bags and Nylon polyester Cooler Bags?

Non-woven fabric. Because it is a kind of fabric that does not need to be spun and weaves, it just aligns or randomly arranges the textile short fibers or filaments to form a web structure, and then uses mechanical, thermal bonding, or chemical methods to strengthen it. Non-woven fabric breaks through the traditional textile principle and has the characteristics of short process flow, fast production speed, high output, low cost, wide use, and multiple sources of raw materials.

Nylon polyester is woven with the weft-weight flat or square flat weave in the plain weave structure. Its characteristic is that one of the warp and weft yarns is polyester-cotton yarn and the other is pure cotton yarn. The weft yarn is combed; the fine warp and thick weft are used, and the number of weft yarns is generally about 3 times that of the warp yarns, and the polyester-cotton yarns are dyed into colored yarns. , Pure cotton yarn is bleached.

So If you want cheap price material, you can choose non woven for making cooler bags.

If you want to take heavy products, you can choose nylon polyester material.

  3. Due to the low ambient temperature in some areas, the internal thermal insulation aluminum foil will become hard and easy to damage. When the bag is folded, the oven can be used to increase the temperature. Because the heat-insulating aluminum foil becomes soft when exposed to heat, it can avoid loss during folding.
