Watch Out for These Mistakes—They Could Ruin Your Bagging Machine

Do you think maintaining a bagging machine is super complicated and you’re scared of breaking it? Actually, taking care of Hualian pre-made bag bagging machines is almost as easy as cleaning your home rice cooker or sealing machine. It only takes a few simple steps—even beginners don’t have to worry!
First, let’s talk about air supply maintenance. The machine’s air supply is like human breathing—just keep the air pressure at 0.5-0.7Mpa. Check the pressure gauge regularly and adjust it if it’s too low. That way, the machine won’t get stuck when sealing bags.
Next is temperature adjustment. The heat-sealing part works just like a household bag sealer. For CPP film, set the temperature to 50℃; for PE film, set it to 65℃. Choose the temperature based on the material, and the bags won’t stick together.

Now, let’s learn how to replace easy-to-wear parts. The sealing strip of the bagging machine needs to be replaced every 3 months. You can buy one online for only about $2, and you can install it yourself in 5 minutes—no need to call a repairman.
Finally, daily cleaning is a breeze. Wipe the feeding rollers with a soft cloth when they’re dirty, and clean the photoelectric sensor with an alcohol pad. Then the machine will work perfectly.
