Description

Technical Field

[0001] This utility model relates to the field of PVC film technology, specifically to a puncture-resistant composite PVC film. Background Technology

[0002] PVC film possesses excellent transparency, toughness, and heat resistance, making it suitable for packaging food, pharmaceuticals, cosmetics, and other products. However, PVC film has relatively weak puncture resistance. For example, when using PVC film to protect products, multiple layers are typically required to prevent punctures from the product itself or external objects, which is cumbersome. Furthermore, if a PVC film is accidentally punctured, the puncture can easily spread, resulting in inconsistent product protection. Utility Model Content

[0003] The purpose of this invention is to provide a puncture-resistant composite PVC film to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a puncture-resistant composite PVC film, comprising a base film, wherein a mesh layer is provided on the lower surface of the base film, the mesh layer improving the tensile strength of the base film and ensuring that the PVC film is not easily excessively deformed when stretched;

[0005] The folded layer, which is folded into three layers, is connected to the upper surface of the base film to increase the thickness of the PVC film, increase the resistance to foreign object puncture, and ensure that the PVC film is not easily punctured.

[0006] A buffer film is attached to the upper surface of the folded layer. The buffer film improves the cushioning capacity of the PVC film, making it less likely to be punctured when impacted by certain objects.

[0007] The anti-abrasion film is attached to the lower surface of the mesh layer. The buffer film and the anti-abrasion film improve the double-sided puncture resistance of the base film, and the anti-abrasion film is not easily damaged by friction.

[0008] Furthermore, the base film is serpentine, and the mesh layer and folded layer are connected to the base film through an adhesive layer. The adhesive layer fills the serpentine base film, which has a certain tensile elasticity. When subjected to a puncture object, the PVC film prevents puncture by deforming.

[0009] Furthermore, the mesh layer has a four-sided mesh, which prevents the PVC film from being excessively stretched when subjected to a large tensile force, thus avoiding damage to the PVC film due to stretching.

[0010] Furthermore, the upper surface of the buffer film has several buffer bubbles, which improve the impact resistance of the PVC film. During the transportation of the product, the PVC films on the product come into contact with each other, which plays a buffering role and makes them less prone to damage.

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

[0012] (1) Buffer film and buffer bubble improve the buffering capacity of PVC film. When PVC film is impacted by non-sharp objects, the buffer film and buffer bubble relieve the force and prevent PVC film from being punctured.

[0013] (2) The folded layer increases the thickness of the PVC film. When the PVC film is punctured by a sharp object, the folded layer increases the puncture resistance, making the PVC film less likely to be punctured.

[0014] (3) The serpentine base film combined with the grid layers improves the elasticity of the PVC film. When the PVC film is subjected to tensile force, it can relieve the tensile force and prevent the PVC film from tearing due to stretching. Attached Figure Description

[0020] 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.

[0021] Example:

[0022] Please see Figure 1-4This utility model provides a technical solution: a puncture-resistant composite PVC film, including a base film 4, wherein a mesh layer 5 is provided on the lower surface of the base film 4, the mesh layer 5 improves the tensile strength of the base film 4, avoids excessive deformation and damage of the base film 4 due to stretching, and improves the toughness of the base film 4;

[0023] Folded layer 3, which is folded into three layers, is connected to the upper surface of the base film 4, as shown below. Figure 2 As shown, the folded layer 3 is formed by folding a layer of plastic film. The folded layer 3 increases the thickness of the base film 4. When the PVC film is punctured by a foreign object, the folded layer 3 increases the puncture resistance and prevents the PVC film from being easily punctured.

[0024] Buffer film 1 is attached to the upper surface of folded layer 3. Buffer film 1 improves the impact resistance of PVC film and can prevent PVC film from being damaged by impact.

[0025] The anti-abrasion film 6 is attached to the lower surface of the mesh layer 5. The buffer film 1 and the anti-abrasion film 6 improve the double-sided puncture resistance of the base film 4. When the PVC film is rubbed, the anti-abrasion film 6 prevents the PVC film from being easily worn through. The PVC film has strong overall puncture resistance.

[0026] In this embodiment, as Figure 3 As shown, the base film 4 is bent in a serpentine shape. The mesh layer 5 and the folded layer 3 are connected to the base film 4 through the adhesive layer 7. The adhesive layer 7 fills the serpentine bend of the base film 4, which can maintain the flatness of the PVC film. When the serpentine bend of the base film 4 is subjected to tensile force, it resists the tensile force through slight deformation, making the PVC film more tough.

[0027] In this embodiment, as Figure 2 As shown, the anti-wear film 6 is also connected to the mesh layer 5 through the adhesive layer 7. The adhesive layer 7 is provided in three layers, and the mesh layer 5 allows the adhesive layer 7 to pass through, ensuring that the base film 4 and the anti-wear film 6 can be stably bonded.

[0028] In this embodiment, as Figure 4 As shown, the mesh layer 5 has a four-sided mesh, which makes the mesh layer 5 less likely to be torn by pulling, and at the same time gives the mesh layer 5 a certain tensile deformation ability. When the PVC film is stretched, it will not easily break due to stretching.

[0029] In this embodiment, as Figure 1 As shown, the upper surface of the buffer film 1 has a number of buffer bubbles 2. The buffer bubbles 2 improve the buffering capacity of the buffer film 1. When an external impact force acts on the buffer film 1, the buffer bubbles 2 can absorb and disperse these impact forces, thereby effectively protecting the packaged or covered products from damage and preventing the PVC film from being torn due to impact.

[0030] In this embodiment, as Figure 1 As shown, several protective sleeves 8 are fitted onto the surfaces of the buffer film 1 and the anti-wear film 6, and the protective sleeves 8 are located between the buffer bubbles 2. When the PVC film is cut, the protective sleeves 8 protect both ends of the PVC film.

[0031] In this embodiment, as Figure 4 As shown, the adhesive layer 7 forms an adhesive film in the grid layer 5, which helps to improve the stability and durability of the overall structure of the PVC film.

[0032] Specifically, in use, the buffer film 1 and buffer bubble 2 provide excellent pressure resistance, moisture protection, and shockproof protection for various products. During transportation, they reduce damage caused by vibration or collision, ensuring the safety and integrity of the products, and also preventing the PVC film from being torn by external impacts.

[0033] The folded layer 3 increases the overall thickness of the PVC film, thereby significantly enhancing its puncture resistance. During product transportation, storage, or use, the PVC film can better resist punctures from sharp objects, protecting packaged items from damage. Combined with the abrasion-resistant film 6, it can withstand greater physical impacts and abrasions, ensuring that the PVC film is less prone to developing holes due to wear.

[0034] The mesh layer 5 can significantly improve the tensile strength, tear strength and abrasion resistance of PVC film, and enhance the physical properties of PVC film so that it can better resist external impact and wear;

[0035] The buffer film 1, folded layer 3, abrasion-resistant film 6, and mesh layer 5 can effectively prevent PVC film from being torn due to external punctures, friction, impacts, etc., and have strong comprehensive puncture resistance.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
