The following are the main materials and characteristics of non-woven bags

The material of non-woven bags is mainly polypropylene (PP) fiber. Non-woven fabric is a material that bonds fibers together by physical means, rather than by weaving or knitting.
1. Characteristics of non-woven bags:
Lightweight and durable: Non-woven bags are lightweight but very strong, suitable for daily use and carrying items of a certain weight.
Good breathability: Due to the special structure of non-woven fabric, it has good breathability and is suitable for packaging and storing items that require breathability.
Multiple uses: Non-woven bags can be used repeatedly, reducing the use of disposable plastic bags and having good environmental benefits.
Good printability: The surface of non-woven bags is suitable for various printing processes, and different patterns and texts can be printed on them for promotion and advertising.
Non-woven bags are widely used in shopping, packaging, promotion and daily life because of their environmental protection, durability and versatility.

2. The main material of non-woven bags:
Polypropylene (PP): Polypropylene fiber is the main component of non-woven bags. Polypropylene is a thermoplastic polymer with good strength, durability and tear resistance.
Production process: After the polypropylene particles are heated and melted, they are formed into non-woven fabrics through processes such as spinning, web laying and hot pressing. This process does not require weaving or knitting, saving production time and cost.
Environmental protection: Polypropylene is a recyclable material, and non-woven bags can be recycled through appropriate recycling processes after their service life. In addition, polypropylene non-woven bags can be degraded under appropriate conditions to reduce environmental pollution.

Other additives: During the production process, some additives may be added to enhance the properties of non-woven fabrics, such as anti-UV additives, waterproofing agents, antibacterial agents, etc. These additives can be adjusted according to the specific use and needs of the non-woven bags.
