Description

Technical Field

[0001] This utility model relates to the field of membrane technology, specifically to packaging film. Background Technology

[0002] Packaging film is a polymer material used to wrap the surface of food to isolate it from decomposing microorganisms, bacteria, and foreign contaminants, thereby preventing and prolonging food spoilage.

[0003] Currently, when hot food is wrapped in packaging film, the food produces water vapor, which is trapped inside the film and cannot escape, thus accumulating inside. Because the film is relatively cool, the water vapor trapped inside condenses on its surface as it tries to escape upwards. These droplets easily drip onto the food, making it damp and affecting its texture. Utility Model Content

[0004] The purpose of this utility model is to provide a packaging film to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a packaging film, including a film body, wherein the film body has a breathable hole, and a connecting groove is provided on the upper surface of the film body. A sealing sticker for sealing the breathable hole is adhered inside the connecting groove. When the sealing sticker is adhered inside the connecting groove, the upper surface of the sealing sticker is flush with the upper surface of the film body.

[0006] As a further feature of this invention, a first release paper is provided inside the connecting groove, and an adhesive layer for bonding with the first release paper is provided on the lower surface of the sealing sticker.

[0007] As a further feature of this invention, the membrane body is provided with an installation groove, and a second release paper for bonding with the adhesive layer is provided inside the installation groove, and the air vent is opened at the center of the second release paper.

[0008] As a further feature of this invention, the lower surface of the sealing sticker is provided with a sealing sheet for sealing the air vent, the diameter of the sealing sheet being larger than the aperture of the air vent, and the first release paper having a groove for embedding the sealing sheet.

[0009] As a further feature of this invention, the diameters of the connecting groove and the second release paper are both larger than the diameter of the sealing sticker.

[0010] As a further feature of this invention, both the membrane body and the sealing sheet are made of PE material.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] When wrapping hot food, the hot steam generated by the food can be quickly discharged through the vent holes, thus preventing water vapor from accumulating inside the membrane body, preventing the food from becoming damp, and ensuring the taste of the food. After the food no longer generates water vapor, the sealing sticker can be peeled off from the connecting groove and then pasted onto the vent holes. The sealing sticker seals the vent holes, ensuring the sealing effect of the membrane body, thereby isolating decomposing microorganisms, bacteria, and external contaminants from entering, preventing and prolonging food spoilage, and ensuring the normal use of the membrane body.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 , Figure 2As shown, the packaging film includes a film body 1, with ventilation holes 2 formed on the film body 1. A connecting groove 3 is provided on the upper surface of the film body 1, and a sealing sticker 4 for sealing the ventilation holes 2 is adhered inside the connecting groove 3. When the sealing sticker 4 is adhered inside the connecting groove 3, the upper surface of the sealing sticker 4 is flush with the upper surface of the film body 1. Therefore, when hot food is wrapped by the film body, the hot steam generated by the food can be quickly discharged through the ventilation holes 2, thereby preventing water vapor from accumulating inside the film body, preventing the food from getting damp, and thus ensuring the food's safety. The sealing sticker 4 can be peeled off from the connecting groove 3 after the food no longer produces water vapor, and then pasted onto the vent hole 2. The sealing sticker 4 seals the vent hole 2, ensuring the sealing effect of the membrane body. This isolates the entry of decomposing microorganisms, bacteria and foreign contaminants, preventing and prolonging food spoilage, and ensuring the normal use of the membrane body. When the membrane body is rolled up, the sealing sticker 4 is hidden inside the connecting groove 3, making the surface of the membrane body flat and not uneven, thus facilitating the rolling up of the membrane body.

[0019] Please see Figure 1-3 As shown, a first release paper 5 is provided inside the connecting groove 3, and an adhesive layer 6 for bonding with the first release paper 5 is provided on the lower surface of the sealing sticker 4. The adhesive layer 6 is a pressure-sensitive adhesive. By bonding the adhesive layer 6 with the first release paper 5, the sealing sticker 4 can be fixed inside the connecting groove 3. When it is necessary to peel the sealing sticker 4 from the inside of the connecting groove 3, the adhesive layer 6 and the first release paper 5 can be separated relatively easily, making the operation of peeling off the sealing sticker 4 more convenient and labor-saving. An installation groove is provided on the membrane body 1, and a second release paper 7 for bonding with the adhesive layer 6 is provided inside the installation groove. The vent hole 2 is opened at the center of the second release paper 7. By bonding the adhesive layer 6 with the second release paper 7, the sealing sticker 4 can be fixed above the vent hole 2, thereby achieving the sealing of the vent hole 2. When the sealing sticker 4 is not pasted evenly or is pasted crookedly, the adhesive layer 6 can be bonded to the first release paper 5. The two release papers 7 can be easily separated, allowing the sealing sticker 4 to be easily peeled off for adjustment. A sealing piece 8 is provided on the lower surface of the sealing sticker 4 to seal the ventilation hole 2. The diameter of the sealing piece 8 is larger than the diameter of the ventilation hole 2. By sealing the ventilation hole 2 with the sealing piece 8, a sealing effect can be achieved, and the adhesive layer 6 can be prevented from contacting food, thus ensuring the effectiveness of the packaging film. A groove 9 for embedding the sealing piece 8 is provided on the first release paper 5. The diameters of the connecting groove 3 and the second release paper 7 are both larger than the diameter of the sealing sticker 4. When the sealing sticker 4 is pasted into the connecting groove 3, a gap will be left between the sealing sticker 4 and the connecting groove 3, making it easy to peel off the sealing sticker 4. When the sealing sticker 4 is pasted onto the second release paper 7, since the area of ​​the second release paper 7 is larger than that of the sealing sticker 4, it can be pasted more easily. The film body 1 and the sealing piece are both made of PE material, which has good elasticity and toughness and high durability.
