Non woven cloth bags (commonly known as nonwoven bags) are a type of green product that is tough, durable, aesthetically pleasing, breathable, reusable, washable, and can be used for screen printing advertisements and labels. They have a long service life and are suitable for any company or industry to use as advertising and gifts. Consumers get a beautiful non-woven bag while shopping, while businesses get intangible advertising promotion, achieving the best of both worlds. Therefore, non-woven fabric is becoming increasingly popular in the market.
Product Introduction
Coated non-woven bag, the product adopts a casting method, which is firmly compounded and does not stick during the compounding process. It has a soft touch, no plastic feeling, and no skin irritation. It is suitable for the production of disposable medical single sheets, bed sheets, surgical gowns, isolation gowns, protective clothing, shoe covers, and other hygiene and protective products; This type of cloth bag is called a laminated non-woven bag
The product is made of non-woven fabric as raw material, which is a new generation of environmentally friendly material. It has the characteristics of moisture resistance, breathability, flexibility, light weight, non combustible, easy decomposition, non-toxic and non irritating, rich color, low price, and recyclability. This material can naturally decompose after being placed outdoors for 90 days, and has a service life of up to 5 years when placed indoors. When burned, it is non-toxic, odorless, and has no residual substances, thus not polluting the environment. It is internationally recognized as an environmentally friendly product that protects the earth’s ecology.
Misunderstand
Non woven shopping bags are made of non-woven fabric. Many people think that the name ‘cloth’ is a natural material, but it is actually a misunderstanding. The commonly used non-woven fabric materials are polypropylene (abbreviated as PP, commonly known as polypropylene) or polyethylene terephthalate (abbreviated as PET, commonly known as polyester), and the raw material for plastic bags is polyethylene. Although the two substances have similar names, their chemical structures are very different. The chemical molecular structure of polyethylene has strong stability and is extremely difficult to degrade, so plastic bags need 300 years to decompose completely; However, the chemical structure of polypropylene is not strong, and the molecular chains can easily break, which can effectively degrade and enter the next environmental cycle in a non-toxic form. A non-woven shopping bag can be completely decomposed within 90 days. Essentially, polypropylene (PP) is a typical variety of plastic, and its environmental pollution after disposal is only 10% of that of plastic bags.
Process classification
According to different production processes, it can be divided into:
1. Water jet: It is the process of spraying high-pressure fine water onto one or more layers of fiber webs, causing the fibers to entangle with each other, thereby reinforcing the web and providing it with a certain level of strength.
2. Heat sealed non-woven bag: refers to adding fibrous or powdery hot melt adhesive reinforcement materials to the fiber web, and then heating, melting, and cooling the fiber web to reinforce it into a cloth.
3. Pulp air laid non-woven bag: also known as dust-free paper or dry papermaking non-woven fabric. It uses air flow web technology to loosen wood pulp fiberboard into a single fiber state, and then uses air flow method to aggregate the fibers on the web curtain, and the fiber web is reinforced into fabric.
4. Wet non-woven bag: It is a process of loosening fiber raw materials placed in an aqueous medium into single fibers, while mixing different fiber raw materials to make fiber suspension slurry. The suspension slurry is transported to a web forming mechanism, and the fibers are formed into a web in a wet state and then reinforced into a fabric.
5. Spunbond non-woven bag: It is made by extruding and stretching polymers to form continuous filaments, laying the filaments into a web, and then using self bonding, thermal bonding, chemical bonding, or mechanical reinforcement methods to turn the web into non-woven fabric.
6. Melt blown non-woven bag: The process involves polymer feeding, melt extrusion, fiber formation, fiber cooling, mesh formation, and reinforcement into a fabric.
7. Acupuncture: It is a type of dry non-woven fabric that uses the puncture effect of a needle to reinforce a fluffy fiber mesh into a fabric.
8. Stitching: It is a type of dry non-woven fabric that uses a warp knitted coil structure to reinforce fiber webs, yarn layers, non-woven materials (such as plastic sheets, plastic thin metal foils, etc.) or their combinations to produce non-woven fabric.
Four major advantages
Environmentally friendly non-woven bags (commonly known as non-woven bags) are green products that are tough, durable, aesthetically pleasing, breathable, reusable, washable, screen printed for advertising, and have a long service life. They are suitable for any company or industry to use as advertising and gifts.
Economical
Starting from the release of the plastic restriction order, plastic bags will gradually exit the packaging market for items and be replaced by reusable non-woven shopping bags. Compared to plastic bags, non-woven bags are easier to print patterns and express colors more vividly. In addition, if it can be reused a little, it is possible to consider adding more exquisite patterns and advertisements on non-woven shopping bags than plastic bags, because the reuse rate is lower than that of plastic bags, resulting in non-woven shopping bags being more cost-effective and bringing more obvious advertising benefits.
Strong and sturdy
Traditional plastic shopping bags are made of thin and fragile materials in order to save costs. But if we want to make him stronger, we will inevitably have to spend more costs. The emergence of non-woven shopping bags has solved all problems. Non woven shopping bags have strong toughness and are not easy to wear and tear. There are also many laminated non-woven shopping bags that are not only sturdy, but also waterproof, have a good hand feel, and have a beautiful appearance. Although the cost of a single bag is slightly higher than that of a plastic bag, its service life can be equivalent to hundreds, even thousands, or tens of thousands of plastic bags.
Advertising oriented
A beautiful non-woven shopping bag is not just a packaging bag for a product. Its exquisite appearance is even more irresistible, and it can be transformed into a fashionable and simple shoulder bag, becoming a beautiful scenery on the street. Combined with its sturdy, waterproof, and non stick properties, it will undoubtedly become the first choice for customers when they go out. On such a non-woven shopping bag, being able to print your company’s logo or advertisement will undoubtedly bring about significant advertising effects, truly turning small investments into big returns.
Environmentally friendly
The issuance of the plastic restriction order is to address environmental issues. The flipping use of non-woven bags greatly reduces the pressure of garbage conversion. Adding the concept of environmental protection can better reflect the image of your company and its approachable effect. The potential value it brings is not something that money can replace.
Advantages and disadvantages
Advantage
(1) Breathability (2) Filtration (3) Insulation (4) Water absorption (5) Waterproof (6) Scalability (7) Non messy (8) Good hand feel, soft (9) Lightweight (10) Elastic and recoverable (11) No fabric directionality (12) Compared with textile fabrics, it has higher productivity and faster production speed (13) Low price, can be produced in large quantities, and so on.
Shortcoming
(1) Compared with textile fabrics, it has poor strength and durability. (2) It cannot be cleaned like other fabrics. (3) The fibers are arranged in a certain direction, so it is easy to crack from the right angle direction. Therefore, the improvement of production methods mainly focuses on preventing fragmentation.
Product Usage
Non woven bags: As a member of the “Plastic Bag Reduction Alliance”, I once mentioned using non-woven bags when proposing to reduce the use of plastic bags to relevant government departments. In 2012, the government officially issued the “Plastic Ban Order” and non-woven bags were rapidly promoted and popularized. However, many problems were discovered based on the usage situation in 2012:
1.Many companies use ink to print patterns on non-woven bags in order to reduce costs, which poses a great threat to human health. I have discussed in other topics whether printing on eco-friendly bags is environmentally friendly.
2. The widespread distribution of non-woven bags has led to a situation where the number of non-woven bags in some households almost exceeds that of plastic bags, resulting in a waste of resources if they are no longer needed.
3. In terms of texture, non-woven fabric is not environmentally friendly because its composition, like plastic bags, is made of polypropylene and polyethylene, which are difficult to degrade. The reason why it is promoted as environmentally friendly is that its thickness is higher than plastic bags, and its toughness is strong, which is conducive to repeated use and can be recycled and reused. However, this type of cloth bag is suitable for companies that are not very strong and want to promote environmental protection as a replacement for previous plastic bags and paper bags. It is also practical to promote free distribution at exhibitions and events. Of course, the effect is proportional to the style and quality of the self made product. If it is too poor, be careful not to let others use it as a garbage bag.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
