[0025] The following specifically describes a high-temperature resistant plastic bag of an embodiment of the present utility model with reference to the drawings.
[0026] Embodiment
[0027] For ease of understanding, please refer to Figures 1 to 3 , an embodiment of a high-temperature resistant plastic bag provided by the present utility model, comprising a high-temperature resistant plastic bag body 1, wherein the high-temperature resistant plastic bag body 1 includes a first base layer 11, a reinforcing fiber network 12, a second base layer 13, a gas barrier layer 14 and an anti-static coating 15. The reinforcing fiber network 12 is disposed between the first base layer 11 and the second base layer 13. The gas barrier layer 14 is laid on the other side of the second base layer 13. The anti-static coating 15 is laid on the other side of the gas barrier layer 14;
[0028] The reinforcing fiber network 12 is composed of a plurality of glass fibers 121 interlaced vertically and horizontally and interspersed with Kevlar fibers 122 and carbon fibers 123. The shapes of the Kevlar fibers 122 and the carbon fibers 123 on the plurality of glass fibers 121 are in an X shape, and the included angle between the Kevlar fibers 122 and the carbon fibers 123 is ninety degrees.
[0029] It should be noted that the high-temperature resistant plastic bag body 1 is composed of multiple composite materials, including the first base layer 11 and the second base layer 13. The reinforcing fiber network 12 is located between the first base layer 11 and the second base layer 13, and is composed of a plurality of glass fibers 121 interlaced vertically and horizontally and interspersed with Kevlar fibers 122 and carbon fibers 123. The Kevlar fibers 122 and the carbon fibers 123 are arranged in an X shape on the glass fibers 121, and the included angle between them is 90 degrees. The structural arrangement of the glass fibers 121, the inserted Kevlar fibers 122 and the carbon fibers 123 can significantly improve the mechanical strength and thermal stability of the plastic bag, and thus achieve better high-temperature resistance performance. The anti-static coating 15 is coated on the outer side of the gas barrier layer 14 and has an anti-static function.
[0030] Among them, for the lamination of the multiple materials of the high-temperature resistant plastic bag body 1, appropriate adhesives or hot pressing techniques are used to tightly bond the layers together.
[0031] In an alternative embodiment: both the first base layer 11 and the second base layer 13 are made of high-temperature resistant polymer materials.
[0032] It should be noted that both the first base layer 11 and the second base layer 13 are made of high-temperature resistant polymer materials, preferably such as polyimide, polyphenylene sulfide, etc., to ensure that the plastic bag can remain stable at high temperatures.
[0033] In an alternative embodiment: the gas barrier layer 14 is made of aluminum foil or ethylene-vinyl alcohol copolymer.
[0034] It should be noted that the gas barrier layer 14 is laid on the other side of the second base layer 13 and can be aluminum foil or ethylene-vinyl alcohol copolymer EVOH to prevent gas penetration and maintain a stable internal environment.
[0035] In an alternative embodiment: A UV coating is applied to the outer surface of the anti-static coating 15.
[0036] It should be noted that a UV coating is also applied to the outer surface of the anti-static coating 15 to enhance the protection against ultraviolet rays.
[0037] In an alternative embodiment: A heat-sealing strip 5 is fixedly connected to the inner wall of the open end face of the high-temperature resistant plastic bag body 1.
[0038] It should be noted that the heat-sealing strip 5 is fixed to the inner wall of the open end face of the high-temperature resistant plastic bag body 1, which facilitates the sealing of the plastic bag and ensures good sealing performance even under high-temperature conditions.
[0039] In an alternative embodiment: Connectors 2 are fixedly installed on both sides of the two end faces of the high-temperature resistant plastic bag body 1 through nylon rivets 4, and a handle strap 3 is fixedly connected to the two connectors 2 on the same end face.
[0040] It should be noted that the nylon rivets 4 are used to fix the connectors 2. The connectors 2 are distributed on both sides of the two end faces of the high-temperature resistant plastic bag body 1, through which the handle strap 3 can be installed, facilitating movement and carrying.
[0041] In an alternative embodiment: Folding creases 101 are provided in the middle of the two narrower sides of the high-temperature resistant plastic bag body 1.
[0042] It should be noted that the folding creases 101 are provided in the middle of the two narrower sides of the plastic bag, which facilitates the folding of the plastic bag, saves storage space, and also facilitates quick unfolding and use.
[0043] Working principle: The first base layer 11 provides initial temperature protection and chemical stability, ensuring that the plastic bag does not decompose or deform at high temperatures. The reinforcing fiber network 12 is formed by interweaving glass fibers 121, Kevlar fibers 122, and carbon fibers 123, significantly increasing the mechanical strength and thermal stability of the plastic bag, resisting external impacts and high-temperature effects, and preventing tearing and wear. The second base layer 13 further enhances the heat resistance and structural stability, jointly forming a solid protection barrier with the first base layer 11. The gas barrier layer 14 effectively blocks the penetration of gases such as oxygen and water vapor, maintaining the stability of the internal environment and the shelf life of the product. The anti-static coating 15 avoids the accumulation of static electricity, reducing potential safety hazards caused by static electricity, such as fires or explosions, and at the same time enhancing the protection against ultraviolet rays. Meanwhile, the heat-sealing strip 5 facilitates sealing at high temperatures, maintaining the tightness of the internal environment.
