How to create a perfect sealed space in Middle Seal Bag?
Publish Time: 2024-10-01
Middle Seal Bag is a kind of bag widely used in packaging, storage and transportation. Its sealing performance directly affects the preservation quality of the internal items.
1. Choose high-quality materials
Material selection: Use high-quality plastic materials (such as polyethylene and polypropylene) to make Middle Seal Bag. These materials have good corrosion resistance, abrasion resistance and tear resistance, and can effectively prevent the entry of air and moisture.
Moderate thickness: Choose the appropriate bag thickness to ensure good strength and sealing when sealing.
2. Optimize design
Reasonable size: Choose a Middle Seal Bag of appropriate size according to the items to be packaged, avoid the bag being too large or too small, and reduce the gap to prevent air from entering.
Special structural design: Consider using a Middle Seal Bag with an edge seal design to enhance the sealing performance and prevent leakage of the contents.
3. Improve the sealing process
Heat sealing technology: Use a heat sealer or heat press to seal to ensure the complete closure of the bag mouth; the correct temperature and pressure are the key to ensure the sealing effect.
Double seal: In order to improve safety, a double mouth seal design can be used, that is, two heat seals are performed at the mouth of the bag to improve the durability of the seal.
4. Reasonable exhaust
Exhaust valve design: A tiny exhaust valve can be designed on the Middle Seal Bag to allow the internal gas to be discharged while preventing the outside air from entering, further enhancing the sealing.
Vacuum packaging: For some items that are easily oxidized or humid, you can consider using a vacuum pump to extract the air in the bag to form a negative pressure environment and extend the storage time of the items.
5. Pay attention to the storage environment
Keep dry and clean: The sealed bag should be kept dry and clean before use to avoid moisture or contamination of the internal items.
Avoid high temperature and direct sunlight: The Middle Seal Bag should be stored in a cool and dry place to avoid the impact of high temperature on the bag.
6. Regular inspection
Pay attention to the sealing status regularly: Check the seal of the Middle Seal Bag regularly and replace the bags that may be aged or damaged in time to ensure the reliability of the sealing effect.
Pay attention to the label: If necessary, label the contents and date of the packaged items to help management and use.
7. Apply scientific and technological means
Humidity and temperature monitoring: Humidity or temperature monitoring equipment can be placed inside the Middle Seal Bag to keep track of changes in the internal environment and ensure the safety of items.
8. Choose appropriate packaging equipment
Automatic packaging equipment: If the scale is large or the sealing requirements are high, you can consider using automated packaging equipment to improve packaging quality and efficiency.
Through the above steps, the sealing performance of the Middle Seal Bag can be effectively improved to ensure the safety and freshness of the items inside. Choosing appropriate materials, optimizing design, improving sealing technology, and maintaining a good storage environment are all important factors in creating a perfect sealed space.
