How Is The Waterproof Function Of Non-woven Fabric Bags Achieved?

The non-woven fabric bags and handbags on the market now have good quality and low prices, but they basically have a waterproof effect. So, how is the waterproof function of seamless fabric bags achieved? Let's give you a specific introduction below, hoping to help you have a better understanding of non-woven bags.

Many people may know that non-woven fabric is a breathable material that can easily decompose in natural environments. Usually, non-woven bag factories directly use this fabric to make products. The general printing processes include silk screen or offset printing, which do not have any special changes to non-woven fabric. For ink wash printing, the pattern printed on the bag after washing is washed away.

Non woven bag lamination is a production process different from screen printing. Its characteristic is that the printed patterns can achieve photo level effects and can print complex colored patterns. It covers the surface of the non-woven fabric with a layer of PP film, which greatly improves its firmness. At the same time, the non-woven fabric can also play a waterproof role, and the printed patterns on its surface do not fade due to washing.

So, what actually works is this layer of lamination. The reason why the patterns of the non-woven bags we usually use do not fade and are waterproof is largely due to its role in this.
