American dry-laid non-woven fabric: It is a non-woven fabric made by dry-laid short fibers to form a “fiber web” and then reinforced by mechanical, chemical or thermal processing methods.
Spunlaced non-woven bags: spray high-pressure fine water onto one or more layers of fiber webs to entangle the fibers with each other, thereby strengthening the fiber webs and giving them a certain strength.
Heat-sealed non-woven bags: refers to adding fibrous or powdery hot-melt adhesive reinforcement materials to the fiber web, and then the fiber web is heated, melted and cooled to strengthen it into cloth.
Non-woven bags are environmentally friendly products and a relatively common type of packaging bag. They are mainly used for shopping, packaging, advertising, electronics, clothing, decoration and other products.
The biggest feature of non-woven fabrics is that they have environmental protection functions that plastic products do not have, and their natural degradation time is much shorter than that of plastic bags.
American dry-laid non-woven fabric is a non-toxic, odorless and tasteless milky white highly crystalline polymer with a density of only 0.90–“0.91g/cm3, which is one of the lightest varieties among all plastics currently.
It is particularly stable in water, with a water absorption rate of only 0.01% and a molecular weight of about 80,000 to 150,000.
The formability is good, but due to the large shrinkage rate (1%~2.5%), thick-walled products are easy to dent, and it is difficult to meet the requirements for some parts with high dimensional accuracy. The surface of the product is glossy.
