The stretch film vacuum packaging machine is a commonly used packaging device that can seal food in plastic film and effectively extend the shelf life of food. When using the stretch film vacuum packaging machine to package food, the following steps need to be followed:

Preparatory work: Make sure that the stretch film vacuum packaging machine is clean and free of impurities and stains. Check whether the machine is operating normally and whether all components are intact. Clean and disinfect the workbench and work area to ensure the hygiene of the food packaging environment.

Preparing food: The food needs to be prepared in advance and cut into appropriate sizes to fit the packaging machine. Place the food on the food tray and make sure that the surface of the food is smooth and free of stains and flaws. High-moisture or liquid foods need to be wrapped with absorbent paper or plastic wrap to avoid liquid leakage.

Adjusting the parameters of the packaging machine: Adjust the parameters of the stretch film vacuum packaging machine according to the type, size and shape of the food. Generally speaking, the machine has different modes and speeds to choose from. Make sure to choose the mode suitable for food packaging.

Pling the food: Place the food on the workbench of the packaging machine and arrange it neatly as needed. Avoid stacking or overlapping the food to ensure that the food can be fully recognized by the packaging machine.

Sealing and vacuuming: Pull the stretch film to the top of the food and use the automatic sealing function of the machine to seal it. During the sealing process, make sure that the sealing line is even and firm. After that, the machine will automatically start the vacuum pump to pump out the internal gas and create a vacuum environment.

Check the sealing quality: Check whether the sealing line of each packaging bag is intact and make sure there is no gas leakage. If it is found that the sealing quality is poor, it is necessary to adjust the parameters of the packaging machine in a timely manner to ensure that the sealing line is firm.

Cut the packaging film: Take the packaged food out of the machine and use special scissors or cutting tools to cut off the excess stretch film. Make sure the cutting is clean and tidy and try to minimize the use of the remaining stretch film.

Packaging storage: Place the packaged food in a clean, dry and ventilated storage area, avoiding direct sunlight and a humid environment. According to the needs of different foods, refrigeration or freezing methods can be used for storage.

In summary, the steps for using a stretch film vacuum packaging machine to package food mainly include preparatory work, food preparation, adjusting the parameters of the packaging machine, placing the food, sealing and vacuuming, checking the sealing quality, cutting the packaging film and packaging storage. The correct operation of these steps can ensure the quality and hygiene of food packaging and effectively extend the shelf life of food. Manufacturers of stretch film vacuum packaging machines indicate that during the use process, attention should be paid to operational safety and keeping the machine clean to ensure the hygiene and quality of food packaging.
