[0032] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0033] Please refer to Figures 1-10 An embodiment of the utility model provides a highly weather-resistant PE packaging bag, including a bag body 100, a sealing portion 110 is provided at the upper end of the bag body 100, a storage mechanism 200 is provided on the sealing portion 110, and the storage mechanism 200 includes a first buckle 210 and a card cap 240 respectively connected to both sides of the sealing portion 110, and the bag body 100 includes a PE layer 103, a fiber layer 105, an anti-ultraviolet layer 104 and a waterproof layer.

[0034] Specifically, the sealing portion 110 can be used to seal the items inside the bag body 100, effectively preventing the items in the bag from being contaminated by external dust, impurities, etc., ensuring the cleanliness and safety of the package contents, and extending their shelf life and use value. The storage mechanism 200 provides convenience for the user through the cooperation of the first buckle 210 and the card cap 240. When the packaging bag is not in use, it is rolled up and the card cap 240 is buckled onto the first buckle 210 to fix the rolled packaging bag, reducing the occupied space and facilitating storage and carrying.

[0035] Among them, the PE layer 103 has good flexibility and corrosion resistance, providing basic strength and stability for the packaging bag. The fiber layer 105 adopts glass fiber, which greatly enhances the mechanical properties of the packaging bag and improves its tensile strength, tear strength and puncture resistance. The anti-ultraviolet layer 104 adopts nanomaterials, which can effectively block the invasion of ultraviolet rays, prevent the aging effect of ultraviolet rays on the packaging bag, and extend the service life of the packaging bag. The waterproof layer provides the packaging bag with reliable waterproof and moisture-proof performance, protecting the items in the bag from the influence of humid environment.

[0036] The first sealing strip 111 and the second sealing strip 112 are fixedly connected to both sides of the interior of the sealing part 110, and the first sealing strip 111 and the second sealing strip 112 are clamped together. Support strips 120 are provided on both sides of the upper end of the sealing part 110, and handles 300 are provided at both ends of the sealing part 110.

[0037] Specifically, the first sealing strip 111 and the second sealing strip 112 are located on the upper part of the packaging bag, and the interior of the packaging bag is sealed by pressing. The support strip 120 is used to strengthen the upper edge of the sealing part 110 to prevent the upper edge of the sealing part 110 from being pulled and deformed or torn at the opening during repeated use of the packaging bag, thereby improving the quality of the packaging bag. The setting of the handle 300 can facilitate the user to carry or hang the packaging bag.

[0038] The clamping cap 240 is fixedly installed on the elastic band 230, and the upper end of the elastic band 230 is fixedly connected to the connecting block 250, which is fixedly connected to the side of the sealing part 110 away from the first buckle 210. One side of the connecting block 250 is fixedly connected to the second buckle 220. Several clamping blocks 221 are arranged circumferentially inside the first buckle 210 and the second buckle 220, and the clamping blocks 221 are hemispherical. Anti-slip protrusions 222 are arranged on the outer circumference of the first buckle 210 and the second buckle 220, and the anti-slip protrusions 222 are semicircular. After the bag body 100 is rolled up, the clamping cap 240 is buckled with the first buckle 210.

[0039] When the packaging bag is in use, the card cap 240 can be buckled onto the second card cap 220 to prevent the card cap 240 from shaking around. When not in use, the bag body 100 is rolled up, and the card cap 240 is passed around the bag body 100 and buckled onto the first card cap 210 to fix the bag body 100 for easy storage. The first sealing strip 111 and the second sealing strip 112 can also be opened by pulling the first card cap 210 and the second card cap 220 outward to avoid directly pulling the sealing part 110 to cause it to deform. The first card cap 210 and the second card cap 220 are made of the same material and specifications. By setting the card block 221 and the anti-slip protrusion 222, the tightness and stability of the connection between the first card cap 210, the second card cap 220 and the card cap 240 can be improved.

[0040] The waterproof layer has two layers, namely the first waterproof layer 101 and the second waterproof layer 102. The first waterproof layer 101 is arranged on the inner side of the PE layer 103, the second waterproof layer 102 is arranged on the outer side of the anti-ultraviolet layer 104, and the fiber layer 105 is arranged in the middle of the PE layer 103 and the anti-ultraviolet layer 104.

[0041] Specifically, through the combined effects of the first waterproof layer 101, the second waterproof layer 102, the PE layer 103, the anti-ultraviolet layer 104 and the fiber layer 105, the packaging bag has good waterproof, toughness, anti-aging and weather resistance, and has significant advantages in ensuring the safety of items, convenient use, improving performance and extending service life.

[0042] In summary, the working principle of a high weather-resistant PE packaging bag in an embodiment of the present invention is: when in use, the first sealing strip 111 and the second sealing strip 112 can be disengaged by pulling the first buckle 210 and the second buckle 220 outward to open the upper end of the packaging bag, and the items can be placed in the bag body 100. The packaging bag is closed by pressing the first sealing strip 111 and the second sealing strip 112. When not in use, the bag body 100 is rolled up, and the card cap 240 is passed around the bag body 100 and buckled on the first buckle 210 to fix the bag body 100, reducing the occupied space and facilitating storage and carrying. The first waterproof layer 101, the second waterproof layer 102, the PE layer 103, the anti-ultraviolet layer 104 and the fiber layer 105 work together to make the packaging bag have good waterproof, toughness, anti-aging and weather resistance.

[0043] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
