In long-term practice, the company has gradually formed a business philosophy with independent research and development, design and manufacturing capabilities as its positioning. So far, the company has more than 100 invention patents and new utility and appearance patents.

Rich Experience
In 2012, the company launched the world's first non-woven box bag making machine; In 2016, the project pp 3D bag making machine research and development was successful in 2022, and successfully developed plastic 3D bag making machine in 2017; In 2023, a new structured paper square bottom bag making machine was launched, After completing the independent research and development of the four major 3D bag production equipment, we have become a professional manufacturer of packaging 3D bag mechanical equipment.

Our Service
The company adheres to the service tenet of "ZWE offer the best service to win the trust of customers", and strives to create a new era in the 3D bag industry. Focusing on the future, consistently, based on innovation, and strives to create a new era in the three-dimensional bag industry.

Fast productivity
There is no rejecting that a machine works quicker than people. The machine can help you create bags in different tones, sizes, and plans quicker. Moreover, the computerization the machine gives is magnificent and will help you fulfill your task time constraints on schedule.

Utilize assets
The machine makes ideal use of assets and results in the least wastage. You can take care of raw material and feed it into the machine, and it will convey the bag creation measure all alone and leave the undertaking of gathering delivered bags off the transport line for you.

Cost-Effective
We as a whole skill effectively machines have assumed control over the manual creation strategies across ventures, and the non woven bag making industry is no exemption. A nonwoven machine is joined by a few mechanized elements that make the creation cycle easy and productive. Presently, producers don't need to recruit more workers to convey the undertakings and will require a couple of workers to manage them and convey the fundamental errands. This will prompt lesser work costs, greater usefulness, and higher benefits.

Energy effectiveness
The machine consumes less energy and gives more yield. Assuming you need to save money on electrical costs, putting resources into the machine can help.

The working principle of the fully active non-woven bag making machine is to use high-frequency vibration from the welding head to transmit sound waves to the fusion surface of the working material, instantly causing the working material molecules to collide and reach the plastic melting point.

Then, the solid material is quickly dissolved, and the textile can be neatly welded with strong adhesive force. Using non-woven fabric as the raw material, the machine is fully active and easy to operate. The fully active non-woven bag making machine is a feeding machine that delivers powder (colloids or liquids) to the packaging machine in real time. The feeding speed is controlled by the photoelectric positioning equipment. The rolled sealing paper (or other packaging materials) is driven by the guide roller to the lapel forming machine, which is bent and then overlapped into a cylindrical shape by the longitudinal sealing device. The material is actively measured and filled into the bag. The transverse sealing device intermittently pulls the bag cylinder downwards during the heat sealing and cutting process, forming a flat bag with three sides of overlapping longitudinal seam sealing, and completing the sealing of a bag.

When making non-woven bags, the non-woven bag making machine does not use traditional stitching, but uses ultrasonic technology for welding, reducing the occurrence of joints due to stitching. In addition, the non-woven bag making machine adopts advanced technology for processing, which will not harm the fabric during the processing and will not cause problems such as burrs and curls.

Lubricants are only required for their internal lubrication, but their choice is very simple, but in most cases it is best to adjust their internal and external lubrication to a certain extent.

The internal and external lubrication function of a lubricant is determined by its chemical composition, polarity, and solubility in the polymer melt. For example, stearic acid monoglyceride is soluble in the polyvinyl chloride melt and has partial internal lubrication. Its internal lubrication function comes from the action of two polar hydroxyl groups in the molecule; while glyceryl tristearate has only external lubrication function. Because it has no hydroxyl groups in its molecule. Of course, the lubrication function is also affected by impurities and other additives contained in the lubricant.

Non-woven bag making machine plastic lubricants range from natural materials such as montan wax, paraffin, mineral oil, animal and vegetable oils to various low molecular weight polymers such as low molecular weight fluororesins, silicone oils, low density polyethylene. Etc. More commonly used are some aliphatic compounds such as stearic acid, stearic acid soaps, and acid esters. And amide compounds.

More than 10,000 tons of lubricants were used in plastic processing. The total amides accounted for 45%, stearic acid and its derivatives accounted for 35%, and wax compounds were again. Some lubricants, such as oleic acid amide, stearic acid amide, and hard metal salts of fatty acids (cadmium citrate) are themselves excellent anti-stickers. Non-woven bag making machine Lubricating oil can be made into a good smoothness by adding 0.5%. Of course, fillers such as silica and clay are also the longest-lasting anti-sticking agents in an amount of 0.1-1.0%, which are often referred to as opening agents. 

Perform routine maintenance
Conduct regular inspections and service of key parts like the forming cylinder, cutting unit, and sealing unit. Clean and lubricate moving parts to prevent overheating and ensure proper operation.

Check and replace worn parts
Examine parts like the cutting blades, sealing tapes or glue rolls, and forming plates for any signs of wear and tear. Dull or damaged parts will produce low-quality bags and reduce productivity. Have spare parts on hand to swap them out when needed quickly.

Keep the area clean
Maintain a clean workspace around your Square Bottom paper bag making machine. Wipe up any oil, cream or debris which can be a slipping hazard or interfere with the equipment. Place trash receptacles nearby for waste paper scraps and trimmed edges. A clean, uncluttered area will allow for easier operation and maintenance.

Perform test runs
Conduct trial runs with scrap paper to ensure the machine functions properly after servicing or part replacements. Check that bags are cutting, sealing, and forming correctly at various speed settings. Make any final tweaks to the machine before resuming full production.
