First, the product uses non-woven materials as raw materials, it is a new generation of environmentally friendly materials, with moisture, breathable, flexible, light weight, non-combustion, easy to decompose, non-toxic and non-irritating, rich colors, low prices, can be recycled, etc. Features. The material can be naturally decomposed for 90 days outdoors, placed in an interior for a period of up to 5 years, non-toxic, odorless, and free of any remaining matter when burned, so that it does not pollute the environment and is internationally recognized as an environmentally friendly product that protects the earth's ecology.
Second, non-woven bag classification

non woven bags raw material
1. The main material of non-woven bags is non-woven fabrics. The non-woven fabric is a non-woven fabric, and it directly utilizes a high-polymer section, short fiber, or filament yarn through a variety of web forming methods and consolidation techniques to form a novel fiber product having a soft, breathable, and planar structure. Advantages: Non-woven bags are cheap, environmentally friendly, and widely used, with prominent advertising positions. Applicable to all types of business activities and exhibition fairs, is an ideal promotional gifts for enterprises and institutions.

2. The raw material of the non-woven fabric is polypropylene, and the raw material of the plastic bag is polyethylene. Although the two materials have similar names, the chemical structure is far from one another. The chemical molecular structure of polyethylene is quite stable and extremely difficult to degrade. Therefore, the plastic bag needs 300 years to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can be easily broken and can be effectively degraded. , And in the non-toxic form into the next environmental cycle, a non-woven bag can be completely decomposed within 90 days.

Third, according to the different production processes can be divided into:
1, Spunlace: It is the high-pressure micro-fine water jet to one or more layers of fiber mesh, so that the fibers are entangled with each other, so that the fiber network can be reinforced and have a certain strength.
2. Heat-sealed non-woven bag: It refers to adding fibrous or powdery hot-melt adhesive reinforcement material to the web, and the fiber web is heated and melted to be cooled and consolidated into cloth.
3, pulp air-laid non-woven bags: also known as clean paper, dry paper non-woven fabrics. It uses the air-laid technology to open the wood pulp fiber board into a single fiber state, and then uses the air flow method to agglutinate the fiber on the reticular curtain, and the fiber network is reinforced again. 4. Non-woven wet-laid bags: The fiber raw materials placed in an aqueous medium are opened into single fibers, and at the same time, different fiber raw materials are mixed to form a fiber-suspended pulp. The suspended pulp is transported to a web forming mechanism, and the fibers are in a wet state. Under the network into a cloth and then reinforced.

5, spunbonded non-woven bags: After the polymer has been extruded, stretched to form a continuous filament, the filaments are laid into a net, and the fiber web is subjected to self-adhesion, thermal bonding, chemical bonding or mechanical The reinforcement method makes the web become a non-woven fabric.
6, meltblown non-woven bags: The process: polymer feed --- melt extrusion --- fiber formation --- fiber cooling --- --- reinforcement into cloth.
7, acupuncture: is a dry non-woven fabric, acupuncture non-woven fabric is the use of puncture needles, the fluffy fiber network will be reinforced cloth.
8, stitching: is a dry non-woven fabric, stitching method is the use of warp coil structure of the fiber, yarn layer, non-textile material (such as plastic sheet, plastic thin metal foil, etc.) or a combination thereof The body is reinforced to make a non-woven fabric.
