For environmentally friendly ink-and-wash printing, the pattern printed after the environmentally friendly bag is washed will be washed away. Non-woven fabric film is a production process different from screen printing. It is characterized by the printed pattern can achieve photo-level effect, can print a variety of complex color patterns, it is covered on the surface of non-woven fabric Layer PP film, so that the non-woven fabric has also been greatly improved in terms of firmness. At the same time, the non-woven fabric can also play a waterproof feature, and the printed pattern on its surface will not fade due to washing. Therefore, it is this layer of film that actually plays a role. The reason why the patterns of the environmental protection bags we usually use are not faded and waterproof is largely due to its role in this.

So the non-woven bag waterproof function is realized in this way, so it is a good choice for people.
