How Does OPP Self-adhesive Bag Ensure The Moisture-proof And Dust-proof Effect Of Packaged Items?
Publish Time: 2025-02-24
OPP self-adhesive bag mainly ensures the moisture-proof and dust-proof effect of packaged items through its material properties and structural design, which is specifically reflected in the following aspects:
1. Material properties
Moisture-proof property of OPP film: OPP (Oriented Polypropylene) film, that is, oriented polypropylene film, has excellent moisture-proof performance. It can effectively block the penetration of external water vapor and prevent the items in the package from getting damp.
Dust-proof performance: In addition to moisture-proof, OPP film also has good dust-proof performance. Its surface is smooth and not easy to absorb dust, which can protect the items in the package from dust.
2. Structural design
Self-adhesive sealability: OPP self-adhesive bag adopts self-adhesive design, which can firmly adhere to the bag mouth to form a tight seal. When the bag mouth is closed, the self-adhesive can ensure that the environment inside and outside the bag is completely isolated, thereby effectively preventing the invasion of moisture and dust.
Edge treatment: The edges of the OPP self-adhesive bag are usually specially treated, such as heat sealing or melting edges, to ensure that the bag mouth is more firmly sealed. These treatments can prevent the bag mouth from loosening due to external forces during long-term storage or transportation, thereby maintaining the moisture-proof and dust-proof effect inside the bag.
3. Application scenarios
Application scenarios: OPP self-adhesive bags are widely used in packaging in the fields of food, electronic products, medical devices, etc. These fields have high requirements for the moisture-proof and dust-proof performance of packaging, and OPP self-adhesive bags can just meet these needs.
OPP self-adhesive bags ensure the moisture-proof and dust-proof effect of packaged items through their material properties and structural design. In actual applications, users should choose the appropriate specifications and types of OPP self-adhesive bags according to specific needs and item characteristics, and follow the correct usage method to give full play to its moisture-proof and dust-proof performance.
