non woven fabric bag manufacturing process
Non-woven bags (also known as non-woven bags, English: Nonwoven bags) are green products that are tough and durable, attractive in appearance, and breathable, reusable, washable, and can be printed on silk, printed, and used for a long period of time.
non woven fabric carry bag
The product is made of non-woven fabrics. It is a new generation of environmentally-friendly materials that are moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic, non-irritating, rich in colors, low in price, and recyclable. 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.

non woven fabric bag manufacturing process
The non-woven fabric is a non-woven fabric, and it directly utilizes polymer chips, short fibers or filaments through a variety of web forming methods and consolidation techniques to form a novel fiber product having a soft, breathable and planar structure. The advantages of non-woven bags compared to traditional plastic bags: Non-woven bags are inexpensive, environmentally friendly, practical, widely used, and have prominent advertising positions. Applicable to all types of business activities and exhibition fairs, is an ideal promotional gifts for enterprises and institutions.
The raw material of the non-woven bag is polypropylene, and the raw material of the plastic bag is polyethylene. Although the two materials have similar names, their chemical structures are quite different. The chemical molecular structure of polyethylene is very 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.
non woven fabric bag manufacturing process
Non-woven fabrics are products that do not require a textile process and are made of fabrics, also called non-woven fabrics. Because it is only required to orient the fabric staple fibers or filaments randomly or form them into a web structure, and then it can be made by mechanical, thermal adhesion or chemical methods. Most non-woven bags are spunbonded non-woven fabrics.
Simply put: the non-woven fabrics are not interwoven or knitted together by a single yarn, but the fibers are directly bonded together by physical means, so when you get the sticky name in your clothes At that time, you will find that it is impossible to extract the thread of the root. Non-woven fabrics break through the traditional textile principles, and have the characteristics of short process flow, high production speed, high output, low cost, wide use, and many raw material sources.

Laminated non-woven bag, the product adopts casting method, it is compound and firm, it is not glued in the compounding process, it has soft hand feeling, no plastic feeling, no skin irritation, it is suitable for single-use medical single sheets, surgical gowns, Separation suits, protective clothing, shoe covers, and other hygiene protection products; this kind of cloth bag called non-woven bags.

Spunlaced non-woven
Spunlacing is the process of jetting high-pressure micro-streams onto one or more layers of fibrous webs, causing the fibers to entangle with each other, so that the web can be reinforced and have a certain amount of strength.
Heat-bonded non-woven
Thermally bonded non-woven fabric refers to a fibrous or powdery hot-melt adhesive reinforcing material added to the web, and the web is heated and melted to be cooled and consolidated into a cloth.
Air-laid
non woven fabric bag manufacturing process
Airlaid non-woven fabrics can also be called non-dust paper, dry papermaking 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 fibers on the reticular curtain, and the fiber network is then reinforced into a cloth.
Wet non-woven
non woven fabric bag manufacturing process
In the wet non-woven fabric, the fiber raw material placed in an aqueous medium is opened into single fibers, and at the same time, different fiber raw materials are mixed to form a fiber suspension slurry, and the suspension slurry is transported to a network forming mechanism, and the fibers are laid in a wet state. Reinforced into cloth.
Spunbonded nonwoven
Spun-bonded non-woven fabrics are laid after the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web, and the webs are then subjected to self-adhesion, thermal bonding, chemical bonding, or mechanical reinforcement. The web becomes a non-woven fabric.
Meltblown nonwoven
non woven fabric bag manufacturing process
The process of meltblown nonwoven fabrics: polymer feed - melt extrusion - fiber formation - fiber cooling - web formation - reinforcement into cloth.
Acupuncture non-woven
A needle-punched non-woven fabric is a kind of dry non-woven fabric. The acupuncture non-woven fabric uses the puncture action of a puncture needle to reinforce the fluffy fiber web into a cloth.
Stitching non-woven
The stitch-bonded non-woven fabric is a type of dry-laid non-woven fabric. The stitch-bonding method utilizes a warp-knitted structure on a web, a yarn layer, a non-woven material (such as a plastic sheet, a plastic thin metal foil, etc.) or a combination thereof. The body is reinforced to make a non-woven fabric.

non woven fabric bag manufacturing process
According to the use of different products can be divided into:
1. Non-woven bags series: non-woven bags, non-woven bags, non-woven shopping bags and so on.
2. Non-woven bags series: non-woven paper bags, reusable shopping bags, packaging bags, non-woven bags.
3. Non-woven products series: non-woven storage boxes, non-woven storage boxes, non-woven suit sets - non-woven suit sets.
4. Jewelry Bag Series: Gift Bags Sling Bags Jewelry Bags Flock Bags, Perfume Bags Pencil Bags Jewelry Bags, etc.

Price editing
1, first of all to confirm the tonnage of non-woven fabrics such as: 80 grams 90 grams 100 grams (note to prevent businesses in the fabric on the virtual grams)
2. Calculate the non-woven formula length*width*gram*tons
(40*30*80 grams*12300/1 tons)
3, printing calculations, non-woven bags is best not to use silk printing, not only low prices are not environmentally friendly, generally about 0.8-1.5 monochrome
Double color *2
4, work with ultrasonic heat, car lines, if you use ultrasound within a hair on it, the car line in the 3 hair
Such a non-woven bag can calculate the price
