As a high-performance packaging material, silicone vacuum bag plays an important role in many fields due to its unique structure and functional characteristics. This article will explore the structure, function and characteristics of silicone vacuum bag in detail to help readers better understand this material.
1. Structure of Silicone Vacuum Bag
Silicone vacuum bag is usually composed of several layers of materials to ensure its excellent performance and durability. These materials include, but are not limited to, silicone layer, nylon layer, polyester layer, and aluminum foil layer. Each layer of material has a specific function and together form the solid structure of the silicone vacuum bag.
Silicone layer: Silicone layer is the main functional layer of silicone vacuum bag with excellent sealing and chemical corrosion resistance. It can tightly fit the packaged items and effectively prevent the penetration of gas and liquid.
Nylon layer: The nylon layer has good mechanical strength and wear resistance, which can protect the silicone layer from external physical damage.
Polyester layer: The polyester layer increases the transparency and glossiness of the silicone vacuum bag, making it more beautiful. At the same time, the polyester layer also has certain barrier properties, which can further prevent the penetration of gas and liquid.
Aluminum foil layer: The aluminum foil layer has excellent heat-insulating and light-shielding properties, which can protect the packaged goods from light and temperature changes.
2. Functions of Silicone Vacuum Bags
The main function of silicone vacuum bags is to provide excellent sealing and vacuum environment to protect the packaged items. By vacuuming, silicone vacuum bags can remove air from the package and reduce the oxygen content, thereby prolonging the shelf life of the packaged items and preventing oxidation and deterioration.
In addition, silicone vacuum bags have the following functions
Moisture-proof and mildew-proof: Silicone vacuum bags can effectively prevent the invasion of moisture and mold, and protect the packaged items from moisture and mold damage.
Dust and insect proof: The sealing performance of silicone vacuum bags can prevent the entry of dust and insects, keeping the packaged items clean and hygienic.
Bumper protection: After vacuuming, silicone vacuum bags can fit tightly to the packaged items to form a certain buffer layer, which effectively prevents collision and extrusion during transportation and storage.
3. Features of Silicone Vacuum Bags
High sealing: Silicone vacuum bags use advanced sealing technology to ensure that the gas and liquid inside the package will not leak out and maintain the integrity of the package.
High strength: The multi-layer composite structure of the silicone vacuum bag gives it excellent mechanical strength and can withstand certain external forces and pressures.
High transparency: The polyester layer of the silicone vacuum bag gives it high transparency, which can clearly show the appearance and condition of the packaged items.
Chemical Corrosion Resistance: The silicone layer has excellent chemical corrosion resistance and can resist the erosion of a variety of chemicals, thus protecting the packaged items from damage.
In summary, the silicone vacuum bag plays an important role in the packaging field with its unique structure, function and characteristics. It can provide excellent sealing and vacuum environment, effectively protect the packaged items from external factors, and extend their shelf life and service life.
