The principle of a stretch film vacuum packaging machine is to use a forming mold. First, the film is heated, and then the forming mold is used to shape the container. Then, the packaging material is loaded into the formed lower film cavity, and then vacuum packaging is carried out. Today, the editor will introduce the precautions to be taken when using a stretch film vacuum packaging machine.


1. Before starting up, check if the compressed air pressure has reached the requested level (above 0.6 bar), and check if all major components are intact, such as heating belts, scissors, and various components of the car. Check together for any other personnel around the machine to ensure safety after startup.

2. Open up the CIP cleaning system and perform pre production cleaning on the feeding system and measuring machine to ensure the cleanliness of the products.

3. Close the main power air switch, turn on the power to start up, set and check the temperature of each temperature controller, apply the film, adjust the color code, apply the coding ribbon, and determine whether the coding date and related characters match the products produced on that day.

4. First, adjust the bag making and check the coding function, and open the feeding system for feeding. When the material reaches the request, first open the bag making mechanism bag and check the vacuum degree and heat sealing quality of the vacuum box. That is, after the bag making reaches the request, start filling the material and proceed with production.

5. During the production process, check the quality of the products at any time, such as whether the basic requirements for products containing shredded vegetables, vacuum degree, heat sealing line, wrinkles, and weight are qualified. If there are any questions, adjust them at any time.

6. Operators are not allowed to arbitrarily adjust some operating parameters of the machine, such as the number of runs, various parameters of servo and frequency conversion. If adjustments are needed, it is necessary to state the section chief and have relevant repair or technical personnel adjust them together; During production, operators can adjust the temperature and some phase angle parameters of each temperature controller appropriately based on the actual situation. However, it is necessary to inform the team leader and section chief first to ensure that all parameters of equipment operation are controlled during the entire production process, ensuring the safe and stable operation of the equipment, and ensuring normal production and product quality.

7. If there are any equipment issues or substandard product quality during production, the machine should be shut down immediately to address the issues. Prohibit handling doubts during machine operation to prevent safety accidents from occurring. If there are significant issues that cannot be resolved by oneself, immediately inform the team leader to have the repair personnel come and handle them together, and hang a safety warning sign saying "Under repair, no startup" together. It is necessary for operators to work together with repair personnel to resolve any doubts and restore production quickly.
