Description

Technical Field

[0001] The utility model relates to the technical field of foaming packaging materials, in particular to an EPE composite packaging film. Background Art

[0002] EPE composite packaging film, also known as polyethylene foam composite packaging film, is a packaging material made of low-density polyethylene ester through physical foaming to produce countless independent bubbles and then compounded with other materials.

[0003] Reference may be made to the existing literature EPE composite packaging film (CN220031403U). By setting die-cutting lines, die-cutting grooves, or a combination thereof, the difficulty of winding can be reduced to a certain extent. At the same time, by setting them at intervals along the length direction, the tensile strength of the film in the length direction can be ensured.

[0004] EPE composite packaging film is often used for packaging and transportation of electronic products, instruments and meters, and household appliances. However, for products that require a higher level of protection, a single EPE composite packaging film is often not thick enough to provide adequate support and cushioning. Multiple EPE composite packaging films need to be stacked together. During transportation or storage, adjacent EPE composite packaging films are not effectively fixed, affecting the stability of the packaging, or they need to be manually bonded with external materials. The operation is cumbersome and increases the workload accordingly. Utility Model Content

[0005] The present invention aims to address the shortcomings of the prior art by providing an EPE composite packaging film. By connecting magnetic strips to the upper and lower end slots of the EPE composite layer, the first magnetic strip can be inserted into the slot of an adjacent EPE composite packaging film to form a magnetic connection with the second magnetic strip. This allows the EPE composite packaging film to be longitudinally spliced during product transportation to increase packaging thickness. The magnetic connection design also prevents the packaging material from shifting during transportation, thereby improving packaging stability.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An EPE composite packaging film comprises: an EPE composite layer main body, two card slots 1 are provided on the top of the EPE composite layer main body, and magnetic strips 1 are connected to the card slots 1 via Velcro; two slots are provided at the bottom of the EPE composite layer main body, card slots 2 are provided in the slots, and magnetic strips 2 are connected to the card slots 2 via Velcro.

[0008] The utility model is further configured such that the Velcro is divided into a Velcro hook surface and a Velcro fleece surface, the Velcro hook surfaces are both connected to the surfaces of the first magnetic strip and the second magnetic strip, and the Velcro fleece surfaces are both connected to the first card slot and the second card slot.

[0009] The utility model is further configured such that the hook surfaces of the Velcro are matched with the sizes of the first and second card slots.

[0010] The utility model is further configured such that the magnetic poles of the first magnetic stripe and the second magnetic stripe are opposite.

[0011] The utility model is further configured such that a self-adhesive layer is provided on the upper surface of the EPE composite layer body except for the card slot, and a dustproof film is connected to the surface of the self-adhesive layer.

[0012] The utility model is further configured so that after the dustproof film is torn off, adjacent EPE composite layer bodies can be longitudinally spliced together via the first magnetic strip and the second magnetic strip.

[0013] The beneficial effects of the utility model are:

[0014] 1. When the thickness of the EPE composite packaging film needs to be increased during product packaging, it can be stacked vertically. The magnetic stripe 1 of the lower EPE composite packaging film can be connected to the slot at the bottom of the upper EPE composite packaging film, so that the magnetic stripe 1 and the magnetic stripe 2 are adsorbed, thereby completing the rapid connection of adjacent EPE composite packaging films, which can effectively improve the packaging stability.

[0015] 2. The magnetic stripe 1 and magnetic stripe 2 of the EPE composite packaging film are connected to the EPE composite layer body by Velcro. You can choose to connect magnetic stripe 1 or magnetic stripe 2 according to actual use needs, and it is also convenient for quick disassembly and replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Reference Figure 1-4 An EPE composite packaging film includes: an EPE composite layer main body 1. The EPE composite layer main body 1 adopts a traditional design, and other materials, such as HDPE film, aluminized film, etc., are laminated on the surface of EPE sheets or film materials. This is usually completed by laminating machines, composite machines and other equipment. This composite process not only improves the mechanical strength of the EPE material, but also enhances its waterproof, moisture-proof, and anti-fouling properties. The EPE sheet after lamination can withstand greater pressure and impact, so it is often used as a packaging material.

[0026] For details, please refer to Figure 3 A card slot 7 is provided at both ends of the upper left and right sides of the EPE composite layer body 1, and a Velcro surface 8 is provided in the card slot 7. At the same time, a Velcro hook surface 6 is connected to the surface of the magnetic strip 2, so that the magnetic strip 2 can be adhered to the card slot 7 through Velcro.

[0027] For details, please refer to Figure 4There are slots 10 at both ends of the bottom of the EPE composite layer body 1, and a card slot 2 9 is provided at the bottom of the slot 10. A Velcro surface 8 is provided in the card slot 2 9. At the same time, a Velcro hook surface 6 is connected to the surface of the magnetic strip 2 4, so that the magnetic strip 2 4 can be adhered to the card slot 2 9 through Velcro.

[0028] Furthermore, the hook surface 6 of the Velcro is matched with the card slot 1 7 and the card slot 2 9 , and the hook surface 6 of the Velcro can be just matched and bonded to the card slot 1 7 and the card slot 2 9 .

[0029] Furthermore, when the second card slot 9 is connected to the second magnetic strip 4 , the first magnetic strip 2 is consistent with the size of the slot 10 .

[0030] Furthermore, the magnetic poles of magnetic stripe 1 2 and magnetic stripe 2 4 are opposite.

[0031] For details, please refer to Figure 2 A self-adhesive layer 5 is provided above the EPE composite layer body 1 except for the card slot 7. The self-adhesive layer 5 can be made of film-type self-adhesive materials such as PET (polypropylene), PVC (polyvinyl chloride), etc. These materials not only have good adhesion, but also have the characteristics of being waterproof, oil-proof, and chemically resistant. They are widely used in the fields of mid-to-high-end daily chemical products, electronic products, etc. The surface of the self-adhesive layer 5 is connected with a dustproof film 3 to ensure the adhesion of the self-adhesive layer 5 during use.

[0032] In this embodiment: when the packaging thickness needs to be increased, a longitudinal stacking method can be adopted. First, the dust-proof film 3 on the surface of the EPE composite layer body 1 is removed, and then the magnetic strip 1 2 and the magnetic strip 2 4 are connected to the card slot 1 7 and the card slot 2 9 of the EPE composite layer body 1 through Velcro, and then the magnetic strip 1 2 is inserted into the slot 10 of the adjacent EPE composite layer body 1, so that the magnetic strip 1 2 and the magnetic strip 2 4 are completely adsorbed.

[0033] At the same time, the self-adhesive layer 5 on the upper surface of the EPE composite layer body 1 can be adhered to the bottom of the adjacent EPE composite layer body 1, and cooperated with the magnetic attraction of the magnetic strip 1 2 and the magnetic strip 2 4 for secondary reinforcement to further ensure the stability of the packaging.

[0034] In another embodiment, when the thickness does not need to be increased, the magnetic strip 1 2 and the magnetic strip 2 4 can be removed, and then the dustproof film 3 on the upper surface can be torn off and pasted on the surface of the product for packaging and protection.

[0035] Working principle: When using the present invention, if the thickness of the EPE composite packaging film needs to be increased during the product packaging process, it can be stacked longitudinally, and the magnetic strip 1 2 of the lower EPE composite packaging film can be connected to the slot 10 at the bottom of the upper EPE composite packaging film, so that the magnetic strip 1 2 and the magnetic strip 2 4 are adsorbed, thereby completing the rapid connection of adjacent EPE composite packaging films, which can effectively improve the packaging stability. At the same time, the self-adhesive layer 5 on the upper surface of the EPE composite layer main body 1 can be adhered to the bottom of the adjacent EPE composite layer main body 1, and the magnetic attraction of the magnetic strip 1 2 and the magnetic strip 2 4 is used for secondary reinforcement to further ensure the stability of the packaging.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this.
