[0019] Example 1 Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model provides a high-barrier, corrosion-resistant aluminum film technical solution: its structure includes an aluminum foil layer 1 and a heat insulation layer 2. The top surface of the aluminum foil layer 1 is provided with a plurality of positioning grooves 11 at intervals, and at least one elastic pull strip 12 is provided laterally in each positioning groove 11. The heat insulation layer 2 is connected to and covers the bottom surface of the aluminum foil layer 1. The left and right edges of the bottom surface of the heat insulation layer 2 are provided with an adhesive strip 21 longitudinally. The adhesive strip 21 is folded and bonded so that the aluminum foil layer 1 and the heat insulation layer 2 form an aluminum film heat preservation bag structure with an opening. The end face of the elastic pull strip 12 facing the heat insulation layer 2 is provided with a folded connection structure.

[0020] Among them, when the adhesive strip 21 is not bonded, its surface has a release film.

[0021] In order to ensure that the aluminum foil insulation bag structure can be tightened when the elastic strap 12 is pulled, the positioning groove 11 and the adhesive strip 21 are parallel to each other.

[0022] In order to enable the heat insulation layer 2 to tighten the items, the left and right ends of the elastic pull strap 12 are glued to the top surface of the heat insulation layer 2 through the positioning groove 11, and the middle part of the elastic pull strap 12 is an arc-shaped structure with the concave side facing down.

[0023] The heat insulation layer 2 is made of pearl cotton.

[0024] For ease of assembly and disassembly, the folding connection structure includes a Velcro barbed surface 121 connected to the left side of the arc-shaped structure notch and a Velcro rough surface 122 connected to the right side of the arc-shaped structure notch.

[0025] During operation, the arc-shaped structure of the elastic band 12 is lifted and squeezed, as shown. Figure 4 As shown, the hook and loop fastener 121 and the loop fastener 122 are bonded together. The elastic pull straps 12 pull the heat insulation layer 2 from both sides at the same time, so that the heat insulation layer 2 is partially contracted, thereby achieving the function of tightening the item.

[0026] To achieve high barrier and corrosion resistance, the top surface of the aluminum foil layer 1 has a protective coating.

[0027] The protective coating is a hard oxide film, which is formed by electrolytic oxidation through surface treatment processes. The thickness of the hard oxide film can reach hundreds of micrometers, and it has both wear resistance and chemical corrosion resistance.

[0028] In normal times, such as Figure 1 As shown, the aluminum film has a sheet-like structure. When it is necessary to keep the item warm, the adhesive strip 21 is folded in half and glued on. Figure 2 As shown, an aluminum foil insulated bag structure with an opening at the top is formed. After the items are placed inside the aluminum foil insulated bag structure, the elastic pull strap 12 is pulled. Under the connection and positioning of the folded connection structure, the left and right ends of the elastic pull strap 12 are pulled towards the middle to pull the heat insulation layer 2, causing the heat insulation layer 2 to shrink and tighten the items. Finally, the opening of the aluminum foil insulated bag structure is sealed with glue or adhesive, which can effectively prevent the items from shaking during transportation.

[0029] Example 2 Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model provides a high-barrier, corrosion-resistant aluminum film technical solution: its structure includes an aluminum foil layer 1 and a heat insulation layer 2.

The end face of the elastic pull strip 12 facing the heat insulation layer 2 is provided with a folded connection structure.

[0030] Among them, when the adhesive strip 21 is not bonded, its surface has a release film.

[0031] In order to ensure that the aluminum foil insulation bag structure can be tightened when the elastic strap 12 is pulled, the positioning groove 11 and the adhesive strip 21 are parallel to each other.

[0032] In order to enable the heat insulation layer 2 to tighten the items, the left and right ends of the elastic pull strap 12 are glued to the top surface of the heat insulation layer 2 through the positioning groove 11, and the middle part of the elastic pull strap 12 is an arc-shaped structure with the concave side facing down.

[0033] The heat insulation layer 2 is made of fiberglass cloth.

[0034] For ease of assembly and disassembly, the folding connection structure includes a Velcro barbed surface 121 connected to the left side of the arc-shaped structure notch and a Velcro rough surface 122 connected to the right side of the arc-shaped structure notch.

[0035] During operation, the arc-shaped structure of the elastic band 12 is lifted and squeezed, as shown.

The elastic pull straps 12 pull the heat insulation layer 2 from both sides at the same time, so that the heat insulation layer 2 is partially contracted, thereby achieving the function of tightening the item.

[0036] To achieve high barrier and corrosion resistance, the top surface of the aluminum foil layer 1 has a protective coating.

[0037] The protective coating is a polyvinylidene fluoride resin coating, which forms a dense protective layer through electrostatic spraying and high-temperature curing. It is resistant to ultraviolet rays, acid, alkali and salt spray, and has a color retention period of 15-25 years.

[0038] In normal times, such as Figure 1 As shown, the aluminum film has a sheet-like structure. When it is necessary to keep the item warm, the adhesive strip 21 is folded in half and glued on. Figure 2 As shown, an aluminum foil insulated bag structure with an opening at the top is formed. After the items are placed inside the aluminum foil insulated bag structure, the elastic pull strap 12 is pulled. Under the connection and positioning of the folded connection structure, the left and right ends of the elastic pull strap 12 are pulled towards the middle to pull the heat insulation layer 2, causing the heat insulation layer 2 to shrink and tighten the items.
