The sealing ability of self-sealing bags is one of its most important features, ensuring the safety and freshness of the items inside the bag.
Sealing Mechanisms
- Self-Adhesive Strip: The sealing area of the self-sealing bag typically has a self-adhesive strip, which is a plastic strip coated with hot melt adhesive that bonds the two layers of plastic film together through pressure, forming a seal.
- Zipper Style: Some self-sealing bags feature a zipper-style seal, similar to a zipper design, using interlocking plastic teeth to create a seal.
- Embossed Seal Style: Also known as blow-molded self-sealing bags, these feature a raised and recessed structure at the sealing area, enhancing the stability and strength of the seal.
Sealing Performance
- Moisture-Proof: Self-sealing bags prevent moisture from entering, keeping the items inside dry, especially suitable for preserving food and dry goods that are easily affected by moisture.
- Oxidation-Proof: Good sealing performance reduces oxygen entry, prolonging the shelf life of food, particularly for oxygen-sensitive items like nuts and dried fruits.
- Pollution-Proof: Self-sealing bags prevent external contaminants from entering, maintaining the cleanliness and hygiene of the items inside.
- Odor-Proof: Self-sealing bags can prevent odors from mixing between different items, preserving the original taste of food.
Seal Strength
- Pressure Resistance: High-quality self-sealing bags can withstand certain pressure after sealing, without easily breaking or leaking due to external force.
- Temperature Resistance: Some self-sealing bag materials have good temperature resistance, allowing use within a specific temperature range, suitable for packaging refrigerated or frozen food.
Ease of Use
- Easy Operation: Sealing the self-sealing bag is simple and quick. Users only need to press lightly to seal it, without the need for extra tools or complex operations.
- Reusable: Many self-sealing bags are designed to be reusable. Users can open and reseal them, making them convenient for multiple uses.
The sealing ability of self-sealing bags is its core function, which not only improves the preservation quality of items but also provides convenience and peace of mind for users. With technological advancements and increasing environmental awareness, the sealing performance and eco-friendly features of self-sealing bags are continually improving.
