Regularly check the shelf life and storage conditions of the heat-sealing film, and pay attention to old batch numbers or heat-sealed films.

Enhance the thickness of the heat seal film.

Use heat preservation and aging to promote the hardening of the adhesive, which can improve the strength and heat resistance of the composite film.

When selecting the heat sealing conditions, choose according to the structure of the composite film, heat sealing state, etc., or improve the heat sealing method, and cool it immediately after heat sealing.

Change the type of the heat-sealing layer film, and select the inner-sealing layer film with anti-pollution heat-sealing properties. 

Non-woven fabrics are required for each part of the non-woven bag making machine, including the front, side, hemming, and handles. The specifications of the fabrics used in each part will also be different, and they must be professionally The tailoring master cuts according to the customer's customized tote bag specifications.

The front and back sides of the non-woven bag making machine can be printed with text, patterns, LOGO, etc. And can also be used for advertising design and promotion. Printing pigments are divided into environmentally friendly pastes, water-based inks, and oil-based inks, and the former is the most used.

The material of the non-woven bag making machine is a new generation of environmentally friendly bag material - non-woven fabric, which is moisture-proof, breathable, flexible, light in weight, non-flammable, easy to decompose, non-toxic and non-polluting, rich in color, Low price, recyclable and so on.

There are usually many colors of non-woven fabrics, and customers can choose according to specific conditions. However, it should be noted that each batch will be affected by factors such as production temperature, resulting in the color difference of the same type of fabric, so when purchasing fabrics, you should calculate how much you need. 

Non-woven bags are in high demand in the market because they can be reused and are eco-friendly. These bags are the best substitutes for plastic bags and are long-lasting. Non-woven bags can create a brand and thus can leave a long-lasting impression in people's minds. These bags are made of non-woven fabrics and are manufactured by high-tech machinery. There are many machines used by the non-woven bag manufacturers and among these machines, B700 and D700 are some of the best non woven bag making machines.

B700 Machine
Non-woven bag making machine- B700 is an advanced and automatic machine used for manufacturing non-woven bags. It is capable of adopting mechanical, electrical, optical, and pneumatic integration technology.
It is suitable for non-woven fabric and produces different shapes and sizes of flat bags, flat bags with D-cut, drawstring bag, bottom gusset bag, bottom gusset bag with D-cut and side gusset bag, vest bag,etc.
This machine is usually used to produce bags with online handles.
It welcomes customized designs of bags.

D700 Machine
Unlike B700, D700 also adopts mechanical, electrical, optical, and pneumatic integration technology. It is an advanced machine incorporated with the function of automatic handle loop bonding offering speed up to 75pcs/min.
This non-woven bag producing machine is suitable for producing non-woven bags in different shapes and sizes including handbags, flat bags, vest bags, and drawstring bags, etc. D700 machine can replace the traditional handle-sealing, reduce labor and manufacturing cost.
This non-woven bag making machine can produce different bags with loop handle directly.
Both B700 and D700 are fully automatic non-woven bag manufacturing machines. These machines offer fine craftsmanship and products of high quality standards.

Uneven non woven bag size
One of the most common problems with both square bottom non woven bag making machines and v bottom non woven bag making machines is the inconsistency in the size of the bags produced. This can be due to issues in the cutting process, tension adjustment, or material feed.

Troubleshooting tips
Check material tension: Ensure that the non woven bag has the correct tension setting. Too much tension can result in overstretching, while too little tension may cause uneven cutting.
Adjust the cutter blade: Dull or misaligned cutter blades often lead to size discrepancies. Regularly check and sharpen or replace the blades.
Inspect material feed: If the feed is inconsistent, check the feed rollers for wear or contamination. Clean or replace the rollers if necessary.

Machine jamming or stoppages
Automatic non woven bag making machines are often subject to jamming or abrupt stoppages during operation. This can occur due to incorrect settings, material blockages, or mechanical failure.

Troubleshooting tips
Inspect gears and moving parts: Regular maintenance and lubrication are key to avoiding mechanical jamming. Look out for worn-out gears or debris in the machine's moving parts.
Check sensors: If your automatic non woven bag making machine has sensors, ensure they are properly calibrated and free of dirt or obstructions.
Verify non woven bag quality: Low-quality or improperly stored non woven bagcan cause jams. Always use the recommended non woven bag grade for your specific machine.

Bag bottom not sealing properly
This issue is often seen in both square bottom non woven bag making machines and v bottom non woven bag making machines. A poorly sealed bottom can render the bag unusable for carrying goods, leading to wastage.

Troubleshooting tips
Check the glue application: Ensure the glue is being applied evenly and in the correct quantity. A clogged glue nozzle or inadequate glue supply can result in poor sealing.
Monitor temperature settings: Some machines use heat sealing methods. Ensure that the temperature is set correctly for the type of non woven being used.
Inspect the sealing roller: The sealing roller should be free of debris and operating smoothly. Misalignment or contamination can hinder the sealing process.

High power consumption
Non woven bag making machine prices vary, and the operating cost is a crucial consideration. High power consumption may not only increase costs but can also indicate inefficiencies in your automatic non woven bag making machine.

Troubleshooting tips
Monitor motor efficiency: Ensure the machine's motor is operating at its peak efficiency. Motors that run hot or make unusual noises may be overworked and in need of replacement.
Check power settings: Some machines have adjustable power settings for different tasks. Ensure you are using the correct setting for your specific production needs.
Inspect electrical components: Regularly check the machine's electrical components, including wiring, switches, and circuit boards, for wear and tear.

Uneven glue application
Uneven glue application can cause significant production downtime in both v bottom non woven bag making machines and square bottom non woven bag making machines. This leads to either excessive glue usage or weak bonding.

Troubleshooting tips
Calibrate glue dispenser: Make sure the glue dispenser is calibrated correctly to apply an even layer. Periodic calibration is important to maintain consistency.
Inspect glue nozzle: A clogged or worn glue nozzle can disrupt glue application. Clean it regularly or replace it if necessary.
Use appropriate glue: Ensure you are using the right type of glue for the machine and the specific type of non woven bag you are producing.

Wrinkling or tearing of non woven
Wrinkling or tearing of the non woven during production is another frequent issue, especially in automatic and non woven carry bag making machines. This problem is often due to incorrect tension, improper roller alignment, or substandard non woven quality.

Troubleshooting tips
Adjust tension settings: If the tension is too tight or too loose, it can cause the non woven to wrinkle or tear. Fine-tune the tension controls until the non woven flows smoothly through the machine.
Check roller alignment: Misaligned rollers can stretch or skew the non woven, leading to tears. Ensure that all rollers are properly aligned and moving freely.
Use quality non woven: Always ensure that the non woven you are using is of high quality and matches the specifications of your machine.
