Precautions for using textured vacuum bags

The textured vacuum bag is co extruded from seven layers of nylon and PE, with one side smooth and the other side textured. The patterns can be in the shape of dots, grids, diamonds, etc. Although the shapes of the patterns produced by different manufacturers are different, their functions are the same. They are all used for channel exhaust during vacuum pumping. Adopting a specially designed textured structure, it can effectively expel air from the packaging bag, slow down the rate of food oxidation, extend the shelf life of food, and effectively prevent food spoilage.
When using textured vacuum bags, in order to ensure their performance and extend their service life, the following are some important precautions:
1. Check the integrity of the bag:
Before use, carefully inspect the vacuum bag for any damage, cracks, or perforations. Even minor defects can cause gas leakage and affect the vacuum effect.
2. Correct size selection:
Choose the appropriate vacuum bag based on the size of the items to be packaged. A bag that is too large may result in incomplete vacuuming, while a bag that is too small may not be able to hold items or cause difficulty in sealing.
3. Cleaning and drying:
Ensure that the items to be packaged and the vacuum bag itself are clean and dry. Moisture and dirt may affect the vacuum effect and the sealing of the bag.
4. Correct sealing:
When using a vacuum machine, ensure that the bag is inserted into the sealing strip and the sealing edge is flat and wrinkle free. Uneven sealing may cause gas leakage.
Follow the operating instructions of the vacuum machine to ensure that the sealing temperature and time are set correctly to achieve good sealing effect.
5. Avoid excessive stretching:
When filling items, avoid over stretching the bag. Excessive stretching may cause the bag to rupture during the vacuuming process.
6. Appropriate vacuuming:
Adjust the vacuum level of the vacuum machine according to the characteristics of the item. For fragile or sensitive items, it may be necessary to reduce the vacuum pumping force to avoid damage.
7. Storage conditions:
When storing vacuum bags, they should be placed in a dry, cool, and ventilated place, avoiding direct sunlight and high temperature environments. High temperature and humidity may accelerate the aging of the bag.
8. Avoid repeated use:
Generally speaking, it is not recommended to reuse vacuum bags. Even if the bag appears intact, its sealing and vacuum effect may have decreased.
9. Pay attention to food compatibility:
For vacuum bags, ensure they are compatible with the food to be packaged. Certain foods, such as acidic foods, may have a corrosive effect on the bag material.
10. Follow the safety guidelines:
When using a vacuum machine, follow the manufacturer's safety guidelines and operating procedures to prevent accidental injury.
In summary, textured vacuum bags are a type of packaging bag with excellent performance and wide applications. Following these precautions can ensure that the textured vacuum bag achieves good results during use and prolong its service life. When selecting and using, please choose according to your own needs and actual situation.
