Non-woven bag (also known as non-woven bag, English: Non woven bags) is a green product, tough and durable, beautiful appearance, good breathability, reusable, washable, silk screen advertising, steamed bread, long service life .
The product is made of non-woven fabric. It is a new generation of environmentally friendly materials. It is moisture-proof, breathable, flexible, light, non-flammable, easy to decompose, non-toxic and non-irritating, rich in color, low in price and recyclable. The material can be naturally decomposed after being placed outdoors for 90 days. It has a service life of up to 5 years. It is non-toxic, odorless and has no residual substances when burned, so it does not pollute the environment.
Non-woven bag principle
The non-woven fabric is a non-woven fabric which directly utilizes high-polymer slicing, short fibers or filaments to form a novel fibrous product having a soft, breathable and planar structure by various web forming methods and consolidation techniques. 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 kinds of business activities and exhibitions and fairs, is an ideal advertising and 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 substances have similar names, the chemical structure is quite different. The chemical molecular structure of polyethylene has considerable stability and is extremely difficult to degrade. Therefore, it takes 300 years for the plastic bag to be decomposed. The chemical structure of polypropylene is not strong, and the molecular chain can be easily broken, so that it 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 fabrics are products that do not require a weaving process and are made of cloth-like cloth, also called non-woven fabric. Because it only needs to orient or randomly woven the short fibers or filaments to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. Most of the non-woven bags are made of spunbonded nonwoven fabric.
To put it simply: non-woven fabrics are not woven and braided together by one yarn, but the fibers are bonded directly by physical means, so when you get the sticky name in your clothes When you find out, you can't draw a single thread. Nonwoven fabric breaks through the traditional textile principle, and has the characteristics of short process flow, fast production speed, high output, low cost, wide application and many raw materials.
Laminating non-woven bag, the product adopts casting method, firm and firm, non-adhesive in the compounding process, soft to the touch, no plastic feeling, no skin irritation, suitable for disposable medical single sheets, bed sheets, surgical gowns, Isolation clothing, protective clothing, shoe covers, and other sanitary protection products; such cloth bags are called laminated non-woven bags.
Non-woven bag production process
The spunlace process is to spray a high-pressure fine water stream onto one or more layers of the fiber web so that the fibers are entangled with each other, so that the fiber web can be reinforced and has a certain strength.
Heat sealing non-woven
The thermally bonded non-woven fabric refers to a fibrous or powdery hot-melt adhesive reinforcing material added to the web, and the web is further fused and cooled to form a cloth.
Airlaid nonwoven fabric can also be called dust-free paper, dry papermaking non-woven fabric. It uses the air-laid technology to open the wood pulp fiber board into a single fiber state, and then uses a gas flow method to agglomerate the fibers on the mesh curtain, and the fiber web is further reinforced into a cloth.
The wet-laid non-woven fabric is to open the fiber raw material placed in the water medium into a single fiber, and at the same time mix different fiber raw materials to form a fiber suspension slurry, and the suspended pulp is transported to a web forming mechanism, and the fiber is netted in a wet state. Reinforce into a cloth.
The spunbonded nonwoven fabric is formed by laminating the filaments after the polymer has been extruded and stretched to form continuous filaments, and the web is subjected to self-bonding, thermal bonding, chemical bonding or mechanical reinforcement. The web becomes a non-woven fabric.
The process of melt-blown non-woven fabric: polymer feeding---melt extrusion---fiber formation---fiber cooling---forming into the net---reinforcing into cloth.
One type of needle-punched non-woven fabric is a needle-punched nonwoven fabric which is punctured by a lancet to reinforce the fluffy web into a cloth.
The stitchbonded nonwoven fabric is a kind of dry non-woven fabric, and the stitching method is a warp knitting fabric structure, a web, a yarn layer, a non-woven material (for example, a plastic sheet, a plastic thin metal foil, etc.) or a combination thereof. The body is reinforced to form a nonwoven fabric.
According to the use of non-woven bags, it can be divided into:
1. Non-woven bag series: non-woven bags, non-woven handbags, non-woven shopping bags, etc.
2. Non-woven bag series: non-woven paper bag, green shopping bag, packaging bag, non-woven handbag.
3. Non-woven products series: non-woven storage boxes, non-woven storage boxes, non-woven suits - non-woven suits.
4. Jewelry bag series: gift bag rope bag jewelry bag velvet bag, perfume bag pen bag jewelry bag and so on.
5. Apron series: advertising apron, polyester apron, cotton apron, PVC apron, hanging net apron.

Shopping bag types:
Shopping bag advertisements can use the limited area of the bag to spread market information about the company or product service to the world. When customers carry shopping bags with store advertisements and walk through the streets, they are actually some exquisite advertising bags, which is no less than making a good advertising sign, but the cost is relatively low.
It prints all kinds of patterns and texts with certain knowledge, such as world famous paintings and Chinese calligraphy, on shopping bags. This kind of shopping bag not only provides convenience for consumers when carrying items, but also cultivates people's sentiments, which makes people have a wonderful psychological feeling.

When the guest puts the gift in a shopping bag with the words "I wish you longevity" and "May be happy", the owner feels not only a gift, but also has some fun in his heart.
Such as the XX Arts Festival Memorial, Travel Memorial Bag, etc. This strategy caters to people's commemorative psychology and honorary psychology, so that people have a new feeling after shopping.
When customers buy miscellaneous items and need simple shopping bags, if the store can provide one, the worry of people, it must be welcomed by consumers. Convenience is an important decision in the promotion.
People generally pursue a high standard of lifestyle, and fashion goods lead the fashion trend of the moment.
