Since plastic bags are being questioned about their environmental effects, nonwoven cloth bags and other alternatives are becoming more popular. Unlike standard plastic bags, nonwoven bags are mostly recyclable and biodegradable, despite being composed of the plastic polypropylene. The salient features are as follows:
What are nonwoven bags?
Shopping bags composed of polypropylene nonwoven fabrics, or sheets of tangled polypropylene fibers bound together by methods such as meltblowing, spunbonding, or spunlacing, are known as nonwoven fabric bags. They look like regular plastic shopping bags and are often transparent and lightweight.
However, the main distinction is that nonwovens made of polypropylene are designed to be recyclable and biodegradable. When disposed of appropriately, the linkages between the fibers can gradually break down because they are not chemically connected.
Why nonwoven fabric bags are beneficial
• Eco-friendly: Polypropylene nonwoven bags are more environmentally friendly than regular plastic bags.
Are largely biodegradable.When disposed of with organic garbage, they can decompose in one to three years.
are recyclable at establishments like grocery stores that take plastic #5.
Reduce how many microplastics you release into the environment.
• Sturdy and lightweight: Polypropylene fibers, which are robust and lightweight, are used to make nonwoven fabric bags. They are not as strong as ordinary plastic bags, but they are still strong enough for moderate use.
• Affordably priced: By employing automated, high-speed processes, polypropylene nonwoven fabric bags can be produced in large quantities at a minimal cost.
• Comparable to plastic bags: They are a good drop-in substitute since they are transparent and maintain the flexibility and form of conventional plastic bags.
Cons of nonwoven bag
• Not completely biodegradable: Some polypropylene resins, whether recycled or virgin, still need to be composted in anaerobic or industrial settings, which is not a common practice.
• Not as sturdy – The bags are not as robust as tightly woven plastic bags since they are not weaved.
How to make non woven bags
1、 Prepare raw materials
The raw materials for non-woven bags include synthetic fiber materials such as polypropylene and polyester, as well as natural fiber materials. In general, the selection of non-woven fabric materials depends on factors such as the purpose of the bag and the geographical environment.
2、 Preparation of chips
Polypropylene particles are melted and spun into filamentous materials, which are then processed into chips through cooling, strengthening stretching, and thermal orientation.
3、 Production of warp and weft yarn
Warp and weft yarn is one of the main materials for making non-woven bags. The warp and weft yarns are made by melting and spinning chips, followed by a series of processing steps to produce non-woven paper.
4、 Organizational non-woven fabric
In the automation equipment of non-woven fabrics, weaving warp and weft yarns into non-woven fabrics is a key link in the production process of non-woven bags.
5、 Non woven fabric forming
Put the organized non-woven fabric rolls into the non-woven bag forming machine for shaping, forming the shape and size of the bag. At this point, add corresponding accessories and straps to the bottom and sides of the bag.
6、 Print and Crop
Print on a non-woven bag printing machine, printing patterns or text on the bag surface. Afterwards, cut and shape the formed non-woven bag.
7、 Packaging and transportation
After the production of non-woven bags is completed, the production process includes cleaning, inspection, packaging, and labeling, and then delivery to the relevant warehouse or transportation department for transportation and sales.
