At present, non-woven bags and environmental protection bags on the market are of very good quality and low price, but they are basically waterproof. But, do you know why these bags are waterproof? Many people may know that non-woven fabric is a kind of environmentally friendly and breathable material, which is easier to decompose in the natural environment. Usually non-woven bag factories directly use this kind of fabric to make products. The general printing process includes screen printing or offset printing. This printing process has no special changes to non-woven fabrics.
Non-woven fabric laminating is a production process that is different from screen printing. Its characteristic is that the printed patterns can achieve photo-level effects and can print various complex color patterns. It is a non-woven fabric surface covering a Layered PP film, so that the non-woven fabric has also been greatly improved in terms of firmness, and can ensure abrasion resistance and strong yarn count. At the same time, the non-woven fabric can also have the characteristics of waterproofing, and the printed pattern on its surface will not be affected by Faded after washing.
Therefore, it is this layer of film that actually plays a role. The environmental protection bags we usually use do not fade and are waterproof. To a large extent, it plays a real role in this.
