Introduction of Non-woven bags

Introduction of Non-woven bags

Non-woven bags is an ECO-friendly product, stronger and durable, beautiful in appearance, good air permeability, reusable, washable, silk-screen advertising, marking, and long service life.
The product is made of non-woven fabrics. It is a new generation of environmentally friendly materials. It has the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in colors, low in price, and recyclable. The material can be naturally decomposed when placed outdoors for 90 days, and the service life can be up to 5 years when placed indoors. It is non-toxic, odorless, and contains no leftover substances when burned, so it does not pollute the environment.

Production principle
Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form new fiber products with soft, air-permeable and planar structure through various web forming methods and consolidation technologies. Compared with traditional plastic bags, non-woven bags have the following advantages: non-woven bags are inexpensive and good-quality, environmentally friendly and practical, widely used, and have prominent advertising positions. It is suitable for all kinds of business activities and exhibitions and fairs. It is an ideal advertising promotion gift for enterprises and institutions.
The raw material of the non-woven bag is polypropylene, while the raw material of the plastic bag is polyethylene. Although the two substances have similar names, their chemical structures are quite different. The chemical molecular structure of polyethylene is very stable and extremely difficult to decompose, so it takes 300 years for plastic bags to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can easily be broken, which can be effectively degraded , And enter the next environmental cycle in a non-toxic form, a non-woven bag can be completely decomposed within 90 days.
Non-woven fabric is a product that does not require a weaving process and is made into a non-woven fabric, also called non-woven fabric. Because it only needs to oriented or randomly support the textile short fibers or filaments to form a fiber network structure, and then use mechanical, thermal bonding or chemical methods to strengthen it. Most non-woven bags are made of spunbonded non-woven fabrics.
To put it simply, non-woven fabrics are not interwoven and braided one by one, but the fibers are directly bonded together through physical methods. Therefore, when you get the sticky weight in your clothes At that time, you will find that you can't draw out the thread ends. Non-woven fabric breaks through the traditional textile principle, and has the characteristics of short process flow, fast production speed, high output, low cost, wide use, and multiple sources of raw materials.
Laminated non-woven bag, the product adopts the casting method, the composite is firm, does not stick during the composite process, it is soft to the touch, has no plastic feeling, and has no skin irritation. It is suitable for disposable medical sheets, bed sheets, surgical gowns, Isolation clothing, protective clothing, shoe covers, and other health protection products; bags made of this kind of cloth are called laminated non-woven bags.

Production Process
Spunlace nonwoven
The spunlace process is to spray a high-pressure fine water stream onto one or more layers of fiber webs, so that the fibers are entangled with each other, so that the fiber webs can be reinforced and have a certain strength.
Heat-bonded non-woven
Thermal bonding non-woven fabric refers to adding fibrous or powdery hot-melt bonding reinforcement materials to the fiber web, and the fiber web is heated, melted and cooled to be consolidated into a cloth.
Airlaid
Airlaid non-woven fabrics can also be called dust-free paper and dry-laid non-woven fabrics. It uses air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses the air-flow method to agglomerate the fibers on the web curtain, and then strengthen the fiber web into a cloth.
Wet non-woven
The wet-laid non-woven fabric is to open the fiber raw materials in the water medium into single fibers, and at the same time mix different fiber raw materials to form a fiber suspension slurry, which is transported to a web forming mechanism, and the fibers are formed into a web in a wet state. Reinforce into cloth.
Spunbond nonwoven
Spunbond non-woven fabrics are formed after the polymer has been extruded and stretched to form continuous filaments. The filaments are laid into a web, and the web is then bonded by itself, thermally bonded, chemically bonded or mechanically reinforced to make The web becomes a non-woven fabric.
Meltblown nonwoven
The process of meltblown non-woven fabric: polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- forming a net --- strengthening into cloth.
Needle punched non-woven
Needle-punched non-woven fabrics are a kind of dry-laid non-woven fabrics. Needle-punched non-woven fabrics use the puncture effect of needles to reinforce the fluffy web into a cloth.
Stitched non-woven
Stitched non-woven fabrics are a kind of dry-laid non-woven fabrics. The stitching method uses the warp-knitted loop structure to bond fiber webs, yarn layers, non-woven materials (such as plastic sheets, plastic thin metal foils, etc.) or their combination The body is reinforced to make a non-woven fabric.

Use classification
According to different product uses, it can be divided into:
⒈Non-woven bag series: non-woven environmental protection bags, non-woven handbags, non-woven shopping bags, etc.

price
1. First, confirm the tonnage of non-woven fabric, such as: 80 grams, 90 grams, 100 grams (note that merchants should not falsely report the number of grams on the fabric)
2. Calculate the non-woven fabric formula length * width * grams * tons
(40*30*80g*12300/1 ton)
3. For printing calculation, it is better not to use silk printing for non-woven bags, not only the price is low, but also not environmentally friendly. Generally, the single color is around 0.8-1.5.
Double color*2
4. The workmanship has ultrasonic heat sealing, the car line, if the ultrasonic wave is less than 1 hair, the car line is about 3 hair
Such a non-woven bag can calculate the price

Bag Application
Advertising type
Shopping bag advertisements can use the limited area of the bag body to disseminate market information about companies or products and services to the world. When customers walk through the streets and lanes carrying shopping bags with store advertisements, they are actually some exquisite advertising bags, no less than making an excellent advertising sign, but the cost is relatively low.
Knowledge-based
It is to print all kinds of patterns and characters 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 and makes people have wonderful psychological feelings.
Gift type
China is a country of etiquette. People always bring gifts to "walk around, walk around" during festivals and birthday celebrations to connect feelings and set off the atmosphere. When the guests put the gifts in the shopping bags printed with the words "Wish you a long life" and "May you be happy", the host feels not only the gift, but also a sense of interest in his heart.
Memorial
Such as XX Art Festival commemoration, travel souvenir bag, etc. This strategy caters to people's mentality of commemoration and honor, so that people have a new feeling after shopping.
Simple type
When customers buy miscellaneous things and need simple shopping bags, if the store can provide one, it will surely be welcomed by consumers. Convenience to others is itself an important know-how in promotion.
Trending
People generally pursue a high-level lifestyle, and fashionable products lead the trend of temporary consumption. When there is something "hot" in the society, if the store prints product patterns and promotional information on beautiful shopping bags, it is undoubtedly an important way to promote sales. When consumers see that hot commodities are available in a certain store, there is an "unstoppable temptation".
Antique type
Many traditional products with high social reputation are popular with consumers due to their exquisite materials, sophisticated production, and long history. If the shopping bag is printed with simple and elegant patterns and text, it will give people a noble and solemn feeling, and it will surely arouse the shopping taste of some consumers.

Printing type

Non-woven bags generally use the screen printing process, which is often referred to as "screen printing", which has always been a common printing process for many manufacturers. It is usually printed manually. Because the printing has peculiar smell, the color is not full and easy to fall off, so many new non-woven printing methods have emerged. Here we introduce the mainstream ones on the market:

Water base ink printing
It is named after its use of water-based elastic glue as the printing medium. It is more common in textile printing and is also called printing. Blend the color paste and water-based elastic glue when printing. No chemical solvents are used when washing the printing plate, and it can be washed directly with water. It is characterized by good tinting strength, strong covering and fastness, washing resistance, and basically no peculiar smell. Generally used for printing: canvas bags,

Gravure printing
The finished products processed in this way are usually called laminated non-woven bags. This process is divided into two steps, that is, the traditional gravure printing process is used to print the image and text on the film, and then the film with the pattern is laminated on the non-woven fabric by the laminating process. Generally, non-woven bags printed with large-area color patterns use this process. It is characterized by exquisite printing, machine production in the whole process, and short production cycle. In addition, the product has excellent waterproof performance, and the durability of the finished product is better than that of non-woven bags produced by other processes. The film is available in bright and matt, and matte has a matte effect! The product is stylish and generous, durable, full color, realistic patterns, the disadvantage is that the price is relatively expensive.
Peritoneal non-woven bag

Heat transfer printing
Thermal transfer printing belongs to special printing! This method requires an intermediate medium, that is, first print the graphics on the thermal transfer film or thermal transfer paper, and then transfer the pattern to the non-woven fabric by heating the transfer device. The commonly used medium in textile printing is thermal transfer film. Its advantages are: exquisite printing, rich layering, comparable to photos. Suitable for small area color image printing. The disadvantage is that the printed pattern is easy to fall off over a long period of time and is expensive.

Non-woven bags are new products that replace white garbage. With the increase of new energy sources, relevant departments advocate environmental protection and energy conservation, and environmental pollution is becoming more and more serious. In order to get rid of this white pollution and make our lives better, many environmentally conscious people People think of a new product-non-woven bags, and its advantages are obvious to all. Woven shopping bags are non-woven fabrics made of plastic. Many people think that cloth is a natural material. This is actually a misunderstanding. Stitched non-woven bags are a kind of dry-laid non-woven fabrics. The stitching method uses the warp-knitted loop structure to bond fiber webs, yarn layers, non-woven materials (such as plastic sheets, plastic thin metal foils, etc.) or their The assembly is reinforced to make a non-woven fabric. Commonly used non-woven fabric materials are polypropylene (PP in English, commonly known as polypropylene) non-woven bags or polyethylene terephthalate (PET in English, commonly known as polyester). The environmental protection is the same as ordinary plastic shopping bags. Neither can be completely degraded. In terms of specific cost performance, non-woven bags under the same conditions are not as strong as plastic bags, and they are not waterproof, and their price is several times higher than that of plastic bags. Needle-punched non-woven fabric bag: It is a kind of dry-laid non-woven fabric. The needle-punched non-woven fabric uses the puncture effect of a needle to reinforce the fluffy web into a cloth. In particular, PP, like PE used in plastic shopping bags, belongs to the five general-purpose plastics, and is a plastic that cannot be degraded even after 50 years of use. The production cost of non-woven bags mainly includes two departments, one is the cost of raw materials, and the other is the processing cost of cloth bags. There are many specifications of non-woven fabrics that can be bought in the market, and the cost is also different. Spunlace non-woven bags: High-pressure fine water jets are sprayed onto one or more layers of fiber webs to entangle the fibers with each other, so that the webs can be reinforced and have a certain strength. Heat-sealing non-woven bag: refers to adding fibrous or powdery hot-melt adhesive reinforcement material to the fiber web, and the fiber web is heated, melted and cooled to reinforce into a cloth. Non-woven bags are environmentally friendly products and are a relatively common type of packaging bags, mainly used for shopping, packaging, advertising, electronics, clothing, decoration and other products. The biggest feature of non-woven fabric is that it has what plastic products do not have
