We all know machine breakdowns are inevitable and unpredictable. But to prevent them or at least keep them from wasting your valuable time, it’s important to be aware of the common problems that may arise when operating a paper bag making machine.
Paper bag making machines are complex, and with complexity comes a variety of things that can go wrong. The statistics show that a large percentage of machine breakdowns are caused by human error, but plenty of other things can cause malfunctions.
In this article,
We’ll explore some of the most common problems associated with paper bag making machines and provide some tips on identifying and troubleshooting them quickly and effectively.
How to troubleshoot common problems with paper bag making machines
Paper bag making machines rely on several systems and components to operate efficiently. Here are some of the most common problems that can occur with paper bag making machines, as well as advice on how to troubleshoot them:
Heat sealing causes leakage

Poor heat sealing can cause the paper bag to leak due to an uneven seal. This is usually caused by incorrect temperature settings, a worn heating element, or an improper seam allowance.
The solution is to adjust the temperature accordingly, replace the heating element if necessary and check the seam allowance. Some paper bag-making machines also have sensors that automatically detect and adjust the temperature.
The plastic of paper bag machine starts to warp
If any parts of the plastic or paper bag machine start to warp, it could indicate a problem with the heating element. This is usually caused by excessive heat not evenly distributed across the material. Some other reasons to check could be the material’s size and shape or the incorrect positioning of the heating element.
The solution is to adjust the temperature accordingly, replace the heating element if necessary, and ensure all materials are properly positioned on the machine. You can also use the right silicone rubber roller cover to ensure the heat is evenly distributed across the material.
Sticking of machine parts
Sticking machine parts is a common problem and can be caused by various things, such as incorrect lubrication, wear and tear on components, or contamination from dust or dirt.
The solution is to inspect all components for damage, replace any worn parts, and ensure that all parts are properly lubricated. If your machine is regularly exposed to dust or dirt, you should also ensure it is cleaned regularly.
Feeding becomes erratic

One of the most common problems with paper bag making machines is erratic feeding. Various factors, such as incorrect material size or thickness, misaligned feed rolls, or worn-out drive belts, can cause this. Some machines with a vacuum feed system may also experience problems due to blockages in the tubing.
The solution is to inspect all components for damage, replace any worn parts, and adjust the material size and thickness accordingly. If the machine has a vacuum system, ensure the tubing is clean and clear of blockages.
Cutter makes poor cuts
If the cutter on your paper bag making machine starts to make poor cuts, it could be a sign of a worn blade or inaccurate alignment. It’s important to check the blade for any signs of wear and tear and to adjust the alignment if necessary. If the blades get rusted, replace them with new ones.
Furthermore, ensure that the material is properly centered before cutting to ensure accurate cuts.
Compression on bags is too low and unstable
If the compression on your paper bags is too low or unstable, it could be caused by incorrect settings, worn-out parts, or a faulty pneumatic system. The speed of the bag formation should be adjusted according to the material type and thickness. When using a pneumatic system, ensure the pressure is adjusted correctly, and all components are in good working order.
It’s also important to check for worn-out parts that may need replacing, such as rollers or cutters. Furthermore, ensure the machine is properly aligned, and all settings are correct.
Flickering of paper tube
If the automatic paper bag making machine starts to flicker while the paper tube is being formed, it could indicate a problem with the temperature settings. The solution is to adjust the temperature accordingly and check for any worn-out parts that need replacing. Some machines also have sensors that detect and adjust the temperature automatically.
In addition, make the tension of the unwinding paper roll tight and align the position of the heat roller. This will ensure the paper tube is formed properly without flickering or distortion.
Jamming of the machine
Jamming of a paper bag making machine is the most occurring problem and can be caused by various things, such as incorrect material size or thickness, misaligned feed rolls, worn-out drive belts, or contamination from dust or dirt. The solution is to inspect all components for damage, replace any worn parts, adjust the material size and thickness accordingly, and ensure that all parts are properly lubricated. The machine should also be cleaned regularly if it is regularly exposed to dust or dirt.
The ink of the printing section is blurring
Ink blurring is another common problem associated with paper bag making machines. The printing will be blurred and unreadable if your ink quality is poor. To prevent this, it’s important to use high-quality ink appropriate for your machine. Additionally, check the printer head for any signs of wear or damage and ensure the settings are adjusted correctly. Finally, inspect all components regularly and replace any worn-out parts as needed.
