Use:
We are usually widely used to pack summer clothes bags, such as shirts, skirts, trousers, baskets, towels, bread and decorations. Usually, this kind of bag has self-adhesive on it, which can be sealed directly after the product is put in. In the domestic market, this bag is very popular and widely used. Because of its good transparency, it is also an ideal choice for packaging gifts. This kind of bag is in great demand in Guangdong, especially in garment processing factories, cloth wholesale markets, small commodity wholesale markets and food industries. Only in summer, the demand of a small-scale clothing factory should reach at least 654.38+0.5 million. If this kind of bag is printed with patterns, its transparency and clarity are incomparable to other plastic bags, which has made a strong publicity for enterprises to promote their brands.

1, adopting frequency conversion speed regulation.
2. Automatically eliminate waste edges
3. Computer digital system is adopted for machine control: fast speed, accurate size and stable operation.
Technical parameters: equipment model ERCM- 1300, bag-making width range 20- 1250 mm, bag-making length range 30-800 mm, bag-making speed 20-50 PCs/min, suitable power supply 220v/50Hz, total power about 6.8kw, overall size 6000× 2200×/KLOC-.
The non-woven bag-making machine sends powder (colloid or liquid) to the hopper above the packaging machine in real time through the feeder, and the introduction speed is controlled by the photoelectric positioning device. The wrapped sealing paper (or other packaging materials) is introduced into the lapel forming machine by the guide roller, bent, laminated and pressed into a cylindrical shape by the longitudinal sealing machine, and the materials are automatically metered and put into the manufactured bag. The transverse sealing machine intermittently pulls down the bag tube while performing heat sealing and cutting, and finally forms a flat bag with overlapping longitudinal seams and sealed on three sides.
Second, the classification of non-woven bags
Non-woven bags are classified by purpose:
1, advertising bag
Shopping bag advertising can use the limited area of the bag to spread the market information of enterprises or products and services to the whole world. When customers walk through the streets with shopping bags printed with shop advertisements, they are actually some beautiful advertising bags, which are no less than making an excellent advertising signboard, but the cost is relatively low.
2, knowledge-based advertising bag
It prints various patterns and words with certain knowledge on shopping bags, such as the world famous paintings and China's calligraphy. This kind of shopping bag not only provides convenience for consumers to carry things, but also cultivates people's sentiment and makes people feel wonderful psychologically.
3. Gift advertising bag
China is a country of etiquette. On holidays and birthdays, people always "walk around" with gifts to connect feelings and set off the atmosphere. When the guest carries the gift in the shopping bag printed with "I wish you a long life" and "I wish you happiness", the host feels not only the gift, but also another benefit.
4. Commemorative advertising bag
Such as art festival memorabilia, tourist souvenir bags, etc. This strategy caters to people's memorial psychology and honor psychology, and makes people feel fresh after shopping.
5. Simple advertising bag
When customers buy miscellaneous things and need simple shopping bags, if the store can provide one to solve people's worries, it will be welcomed by consumers. Giving people convenience itself is an important way to promote sales.
6. Fashion advertising bag
People generally pursue a high-level lifestyle, and fashionable goods lead the temporary consumption trend. When there is a "fever" in society, it is undoubtedly an important measure to promote sales if the store prints product patterns and publicity information on beautiful shopping bags. When consumers see hot-selling goods in a store, there is an irresistible temptation.
7. Antique advertising bag
Many traditional commodities with high social reputation are deeply loved by consumers because of their exquisite materials, excellent production and long history. If simple and generous patterns and words are printed on the shopping bag, it will give people a noble and solemn feeling and will definitely arouse some consumers' interest in shopping.
According to the different production processes, it can be divided into:
Sputtering: high-pressure micro-water is sprayed on one or more layers of fiber web to entangle the fibers, so that the fiber web is strengthened and has certain strength.
2. Heat-sealing non-woven bag: it refers to adding fibrous or powdery hot-melt bonding reinforcing materials to the fiber web, and then heating, melting and cooling the fiber web to strengthen it into cloth.
3. Pulp airlaid nonwoven bag: it can also be called dust-free paper and dry papermaking nonwoven. It uses the air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses the air-laid method to bond the fibers to the net curtain, and the fiber net is reinforced into cloth.
4. Wet non-woven bag: fiber raw materials placed in water medium are opened into single fibers, and different fiber raw materials are mixed to make fiber suspension slurry, which is conveyed to the web-forming mechanism, and the fibers are web-formed in wet state, and then reinforced into cloth.
5. Spunbonded nonwoven bag: After the polymer is extruded and stretched to form continuous filaments, the filaments are laid into a net, and then the net is overheated, chemically or mechanically bonded by itself, thus making the net a nonwoven fabric. 6. Melt-blown nonwoven bag: Its technological process is: polymer feeding-melt extrusion-fiber forming-fiber cooling-web forming-enhanced cloth forming.
7. Needle punching: It is a dry non-woven fabric. Needle-punched nonwovens use the puncture effect of needles to strengthen fluffy fiber webs into cloth.
8. Sewing: It is a dry non-woven fabric. Sewing is to strengthen the web, yarn layer, nonwoven materials (such as plastic sheets, plastic foils, etc.). ) or a combination thereof, by using a warp knitting loop structure.
According to the different uses of products, it can be divided into:
1, non-woven bag series: non-woven environmental protection bag, non-woven handbag, non-woven shopping bag, etc.
2. Non-woven bag series: non-woven file bag, reusable shopping bag, packaging bag and non-woven handbag.
3. Non-woven products series: non-woven storage box, non-woven storage box, non-woven suit cover-non-woven suit cover.
4. Jewelry bag series: gift bag, rope bag, jewelry bag, flannel bag, perfume bag, pen bag, jewelry bag, etc.
Apron series: advertisement apron, polyester apron, cotton apron, PVC apron and tag apron.
Third, the production process of non-woven bag
Non-woven bags generally use screen printing technology, which is often called "screen printing", and has always been a common printing technology used by many manufacturers. Generally, manual printing is used, and it is difficult to control the color in the process, so many new non-woven printing methods have appeared. Here we introduce several mainstream models in the market:
However, with the continuous improvement of customers' requirements for exquisite printing and environmental protection, many new non-woven printing methods have emerged. Here we introduce the mainstream on the market:
I. Watermarking
Named after using water-based elastic mucilage as printing medium, it is more common in textile printing, also known as printing. When printing, the color paste is mixed with water-based elastic glue. When developing the printing plate, chemical solvent is not needed, and it can be washed directly with water. It is characterized by good coloring power, strong hiding power and fastness, washability and basically no odor.
Second, gravure printing.
The finished product processed by this method is usually called laminated non-woven bag. This process is divided into two steps, that is, the traditional gravure printing process is used to print pictures and texts on the film, and then the film printed with patterns is compounded on the non-woven fabric through the laminating process. This process is generally used in non-woven bags printed with large-area color patterns. It is characterized by exquisite printing, full machine production 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. There are two kinds of films to choose from: bright film and matte film, and matte film has matte effect! The disadvantage is that it conflicts with the concept of environmental protection because the film is difficult to degrade.
Third, thermal transfer printing
Thermal transfer belongs to the special printing in printing! This method requires an intermediate medium, that is, printing pictures and texts on a thermal transfer film or paper, and then heating them with a transfer device to transfer the patterns to a non-woven fabric. The commonly used medium in textile printing is thermal transfer film. Its advantages are: exquisite printing, rich hierarchical versions, comparable to photos. Suitable for small area color image printing. Disadvantages are high price and high printing cost. Use:
Used to produce various plastic-plastic, paper-plastic composite materials.

12. Batch delivery function: the workbench has batch delivery function, and the batch delivery quantity can be preset. Cutting system of bag-making machine
The cutting system consists of cutter, length regulator, overrunning clutch and weld regulator. 1.Cutter: It is the most important part of the system. It is a floating mechanism with a moving knife and a sliding guide rail, which is pressed by a spring. The upper and lower cutters can be adjusted. There are adjusting screws in it, which can be used to adjust the tightness of the cutter, which can well eliminate the phenomenon that raw materials are difficult to cut.
2. Bag-making length adjuster: adjust the bag-making length by changing the position of the connecting rod sleeve on the eccentric tray, and adjust the bag-making size by adjusting the handwheel and nut.
3. Overrunning clutch: The Chinese-plastic overrunning clutch is an important part of this machine, and its quality and performance directly affect the product length error. However, due to its high working frequency, its service life is limited. If there is an error in the bag-making length in the production process (usually after half a year of continuous production) and other faults cannot be solved, the clutch can be disassembled for inspection and maintenance.
4. Adjustment of the distance between the welding wire and the cutting line: The distance between the welding wire and the cutting line is generally 5-10 mm. Turn the handwheel on the adjustment frame to make the bundle roller rise or fall for a certain distance to get the ideal cutting line. In order to observe the quality of welding wire conveniently, the welding wire position of single bobbin thread can be adjusted to the outer end of the machine tool. If the welding wire is not parallel to the bottom line, loosen the fastening screw of the bevel gear and turn the handwheel to raise or lower one end of the beam roller; After the production is stable, lock the screw of the gear.
5. Adjustment method of welding knife: put a piece of tissue paper on the support seat, turn the big handwheel in the cabinet by hand to make the welding knife at the bottom dead center, loosen the nut and adjust the nut, and try to pull the compaction degree at both ends of the tissue paper by hand until it is about equal. After adjustment, lock the nut to prevent loosening.
6. Automatic light-controlled feeding device: This device consists of servo motor, feeding rubber roller, light-controlled film cover, curtain, photoelectric tracker and electric control line, and its function is to keep normal film feeding in the production process. When the machine is running, when the film feeding speed is too fast to cover the light-controlled light, the device will give an instruction to stop the motor rotation and film feeding.
