[0028] The present invention will be further described in detail below with reference to embodiments:

[0029] Example 1

[0030] like Figures 1-5The utility model provides a kind of double-layer easy-to-tear packaging bag, including bag body 1, sealing assembly 2 and two handles 3.The material used by packaging bag bag body is usually kraft paper material, kraft paper has good mechanical strength and tenacity, tear and tear resistance.Kraft paper is usually made of renewable fiber, and has strong biodegradability, meets modern environmental protection requirements, and has relatively small burden on the environment after use.Kraft paper packaging bags or boxes can be reused, improving resource utilization efficiency.Sealing assembly 2 is fixedly connected with bag body 1, mainly used for the bag mouth of bag body 1 is encapsulated and handled, prevents the goods in packaging bag from falling out of the bag mouth due to unstable transportation.Two handles 3 are rotatably connected with bag body 1, mainly to facilitate operator to lift packaging bag by handle 3.Sealing assembly 2 includes two sealing plates one 21, sealing plate two 22, two adhesive plates 23 and self-adhesive layer 24.Sealing plate one 21 and sealing plate two 22 use corrugated paper as the material, and corrugated paper (corrugated paperboard) is a kind of strong and light material formed by multiple layers of paper through adhesive bonding.Corrugated paper structure is usually composed of three layers: two flat paper layers and one corrugated middle paper layer, which performs well in bearing and compression.Sealing plate one 21 is fixedly connected with one of adhesive plate 23, and sealing plate two 22 is fixedly connected with the other adhesive plate 23.Adhesive plate 23 uses corrugated paper as the material, and has a multilayer structure, which can increase its tenacity.Solidifying agent can also be added to the paper to increase the rigidity and hardness of adhesive plate 23.Self-adhesive layer 24 is cemented with two adhesive plates 23 on both sides.Self-adhesive layer 24 usually uses a hooked connection belt."Hooked connection belt" is a belt used for connecting and fixing objects, usually made of two different materials: one side is a fiber with small hooks (hook), and the other side is a fiber with small hairs (hair).Hooked connection belt is easy to operate, easy to open and close, and can adjust the tightness according to needs, adapt to different object sizes and shapes, and can be disassembled and assembled multiple times, improving its durability.Hooked connection belt is usually made of synthetic fibers such as nylon or polyester, with good durability and strength.

[0031] As Figures 6-8As shown, the bag body 1 includes a packaging layer 11, an inner liner 12, and four connectors 13. The packaging layer 11 is the layer that directly contacts the outside world, and its surface usually needs to be waterproofed. The usual operation is to coat a layer of polyurethane on the surface of the packaging bag to form a strong waterproof layer. Water-based polyurethane or water-based acrylic paint is used for surface treatment, which is more environmentally friendly than traditional solvent-based paint and has low volatile organic compound (VOC) content. Wax-based waterproofing agents such as beeswax or plant wax can also be used, which are natural materials that provide waterproofing and are safe and harmless. The inner liner 12 is arranged inside the packaging layer 11 and is cemented with the packaging layer 11. The inner liner 12 is usually made of renewable regenerated fibers, such as recycled polyester (rPET), which not only helps to reduce plastic waste, but also saves resources and energy and promotes sustainable development. It can also further increase the waterproof performance of the packaging bag to prevent the contents from being affected by external water and affecting its use. The inner liner 12 can also use a mesh structure material, which can improve the toughness of the packaging bag when in use and thus improve the service life of the packaging bag. The four connectors 13 are symmetrically arranged and fixedly connected on both sides of the packaging layer 11, usually using rivets for fixation. Rivets can provide stronger mechanical connection than adhesives and can withstand greater tensile and shear forces, making them suitable for carrying higher weights. Rivet connections are not easily affected by environmental factors such as temperature and humidity, and have good durability and stability. The handle 3 is rotatably connected to the two connectors 13 on the same side at both ends, without affecting the operation of storing the packaging bag itself.

[0032] A plurality of grooves 31 are arranged in a ring array on the handle 3 to increase the friction between the handle 3 and the contact surface. Even if the operator has water stains or stains on his hands, he can easily lift the packaging bag under the action of the grooves 31 without reducing the friction between his hands and the handle 3, increasing the safety of the packaging bag in use.

[0033] The sealing assembly 2 further comprises two fixed strips 27, two tearable strips 25 and two strip tail adhesive blocks 26. The two fixed strips 27 are respectively fixedly connected with the two sides of the bag body 1. The fixed strips 27 are usually made of plastic material and are connected with the bag body 1 by sewing or rivet connection. The sealing plate one 21 is fixedly connected with one of the fixed strips 27, and the sealing plate two 22 is fixedly connected with the other fixed strip 27. The two tearable strips 25 are respectively fixedly connected with the sealing plate one 21 and the sealing plate two 22. The connection between the two tearable strips 25 and the sealing plate one 21 or the sealing plate two 22 is linearly perforated. When tearing the tearable strip 25, the tearable strip 25 can be easily torn along the perforation between the tearable strip 25 and the sealing plate one 21 or the sealing plate two 22, which is very convenient. The two strip tail adhesive blocks 26 are respectively fixedly connected with the two tearable strips 25. The two strip tail adhesive blocks 26 are used to facilitate the user to tear off the tearable strip 25. When not in use, one end is fixedly connected with the tearable strip 25 and the other end is glued with the packaging layer 11.

[0034] The double-layer tearable packaging bag further comprises a reinforcing net 4 to further improve the overall strength and durability of the packaging. The reinforcing net 4 is arranged in the inner liner 12 and located at the bottom of the inner liner 12. The reinforcing net 4 is fixedly connected with the inner liner 12. The reinforcing net 4 can effectively disperse the additional external force of the packaged items, such as vibration generated during stacking and transportation, so that the performance of the entire packaging bag is significantly improved. In turn, the packaged items will not fall out of the bottom of the packaging bag due to their high weight and extrusion during transportation. The reinforcing net 4 has a net structure for increasing the strength of the bottom of the inner liner 12. The design of the net structure allows uniform distribution of the load, reducing the pressure on individual support points. This load dispersion feature enhances the stability and durability of the overall structure. The net structure has a certain flexibility and can absorb impact under external force without easily breaking or deforming. In turn, the service life of the packaging bag is improved.

[0035] The working principle of the double-layer tearable packaging bag will be described in detail below.

[0036] As shown in Figures 1-8 When loading the items, first open the self-adhesive layer 24 of the packaging bag, then open the bag opening of the packaging bag, put the items to be packaged into the packaging bag, and then close the self-adhesive layer 24. Then rotate the two handles 3 towards the bag opening, and then lift the packaging bag.

[0037] When taking out the article, it can be taken out in two ways, one is to open the self-adhesive layer 24, then take out the article, and close the self-adhesive layer 24 after taking out the article, which is suitable for the case that the subsequent packaging bag still needs to be sealed. The other way is to tear off the two strip tail adhesive blocks 26 from the packaging layer 11, then pull the two strip tail adhesive blocks 26, further make the two tearable strips 25 connected with the two strip tail adhesive blocks 26 tear along the connection of the two tearable strips 25 and the sealing plate one 21 and the sealing plate two 22, because the connection of the two tearable strips 25 and the sealing plate one 21 and the sealing plate two 22 is linearly punched, so when tearing, it is more convenient and labor-saving. Then, the sealing plate one 21 and the sealing plate two 22 and the self-adhesive layer 24 are taken off from the packaging bag, and the opening purpose is achieved. This way is suitable for the case that the article is more convenient and fast to use next time. The two ways of opening the packaging bag increase the convenience of using the packaging bag, and also increase the applicability of the packaging bag in daily use.

[0038] The above has made a detailed description of the utility model in general, but some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, the modifications or improvements without departing from the spirit of the utility model are within the protection scope of the utility model.
