Publish Time: 2024-09-16
Eight Side Sealing Bag is an efficient form of food packaging. It has unique advantages in freshness preservation and moisture prevention due to its excellent sealing and airtightness.
1. Fully enclosed structure
Eight-side seal design: Eight Side Sealing Bag forms a completely enclosed structure through four-side seals and two upper and lower seals, ensuring that the bag is sealed all around, effectively preventing the intrusion of external air and moisture.
Leak-proof design: Its multiple seal design provides higher sealing, avoiding air leakage or leakage caused by loose sealing of the bag.
2. High-performance materials
Multi-layer composite materials: Eight Side Sealing Bag usually uses multi-layer composite materials, such as aluminum foil, polyester (PET), polyethylene (PE), etc., which have excellent gas isolation and moisture-proof properties.
Strong barrier properties: The design of the composite material makes the bag have excellent barrier properties, which can effectively isolate oxygen, moisture and light, and slow down the oxidation and corruption process of food.
3. Airtightness design
Heat sealing process: The high-temperature heat sealing process is used to make the sealing part of the bag have high-strength sealing, reducing the penetration of air and moisture.
Seamless edge sealing: The precise edge sealing process ensures the sealing of the bag sealing part, without gaps or weak points, effectively preventing the influence of external factors on food.
4. Moisture-proof function
Moisture-proof coating: Some Eight Side Sealing Bags are coated with a moisture-proof coating on the inner layer, which can further enhance the moisture-proof performance of the bag and keep the internal food dry.
Desiccant: Desiccant bags (such as silica gel bags) can be added during the packaging process to further control the humidity in the bag and prevent moisture from affecting the food.
5. Light isolation
Aluminum foil layer: Some Eight Side Sealing Bags use an aluminum foil layer, which can effectively block light, prevent the influence of light on food, and extend the shelf life of food.
Light-shielding design: The outer color and material design of the bag takes into account the light-shielding effect to reduce direct exposure of light to food.
6. Optional gas replacement technology
Gas replacement packaging: In some cases, Eight Side Sealing Bag can adopt gas replacement technology, that is, nitrogen or other inert gases are placed in the bag to replace air, further reducing the oxygen content and reducing the oxidation and deterioration of food.
7. Seal inspection
Seal strength test: During the production process, the seal of Eight Side Sealing Bag is usually tested for strength to ensure that each seal meets the design standards, thereby ensuring the sealing and moisture-proof effect of the package.
8. Tear-resistant design
Reinforced structure: The material and structural design of Eight Side Sealing Bag usually have strong tear resistance to avoid affecting the preservation effect of food due to damage to the packaging bag.
9. Easy to store
Folding design: Eight Side Sealing Bag has a compact design, which can effectively save storage space, and is easy to stack and transport, helping to maintain the integrity of the package and the quality of the food.
Eight Side Sealing Bag provides excellent preservation and moisture-proof effects with its fully enclosed structure, high-performance materials, airtight design, moisture-proof function, and light isolation. Through these designs and technologies, Eight Side Sealing Bag can effectively extend the shelf life of food, maintain the freshness and original flavor of food, and provide consumers with high-quality food packaging solutions.
