Description

Technical Field

[0001] The utility model belongs to the technical field of packaging films, and more specifically, relates to an environmentally friendly composite packaging film. Background Art

[0002] Polyethylene is a synthetic plastic resin that can be processed into packaging film to protect workpieces. In industry, it is often made into packaging to seal workpieces. The bubbles outside the inner diaphragm can achieve shock absorption, and shock absorption is the main effect.

[0003] Based on the above, the packaging films currently used are made of separate bubble films or aluminum-plated films, which have relatively targeted protection and are inconvenient to ensure shock absorption and temperature protection at the same time. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an environmentally friendly composite packaging film to solve the problem proposed in the above background technology that the existing packaging film is made of a separate bubble film or an aluminum-plated film, which has relatively targeted protection and is inconvenient to ensure shock absorption and temperature protection at the same time.

[0005] The purpose and effect of the environmentally friendly composite packaging film of the utility model are achieved by the following specific technical means:

[0006] An environmentally friendly composite packaging film includes a main packaging film, wherein the main packaging films are provided in two groups and the middle portions of the two groups of main packaging films are bonded together by hot melting; the main packaging film is made of low-density polyethylene; a buffer film bubble is integrated into the main packaging film, and the buffer film bubble between the two groups of main packaging films is filled with air; an aluminized film is attached to the outside of the main packaging film; and a pyramid bin is integrally provided on the outside of the aluminized film.

[0007] Furthermore, the buffer film bubble of the primary packaging film is aligned with the pyramid bin.

[0008] Furthermore, the pyramid bin and the buffer film bubble are sealed and bonded with environmentally friendly polyurethane glue in a vacuum environment.

[0009] Furthermore, a spacing zone is provided between the main packaging film and the aluminized film, and no buffer film bubble and pyramid bin are provided at the spacing zone.

[0010] Furthermore, the sides of the main packaging film and the aluminized film are both provided with docking holes, and the docking holes on the outside of the main packaging film and the aluminized film are aligned.

[0011] Furthermore, rivets can be passed through and fixed in the docking holes.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The buffer film bubble provides a buffering and shock-absorbing function. The space between the buffer film bubble and the pyramid bin provides a heat-insulating effect, which can greatly reduce the temperature transmission and provide a heat-insulating effect. It is easy to combine, and the three can be hot-melted at the same time to form a composite packaging film, which can provide a buffering function, delay the temperature transmission, and provide a heat-insulating effect. It can be used to provide heat-insulating, shock-absorbing and fall-proof functions for equipment or objects.

[0014] The aluminized film has a protective effect and is relatively hard. It is equipped with a pyramid chamber, which is strong enough to withstand a small vacuum inside. It can also reflect light and prevent natural heating.

[0015] The docking holes provide a fixing function. When it is necessary to make packaging bags, after folding the main packaging film and the aluminized film, rivets are passed through the docking holes, and rivet rings are used in combination with rivets to achieve fixation, thereby increasing the stress of the main packaging film and ensuring that it forms a bag shape. In addition, sewing and fixing can still be performed by passing sutures through the docking holes. In addition to the above methods, the packaging film can also be directly fixed to the outside of the equipment or object using the docking holes. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The embodiments of the present invention are described in further detail below with reference to the accompanying drawings and examples.

[0024] Example 1:

[0025] As attached Figure 1 To the attached Figure 5 As shown:

[0026] The utility model provides an environmentally friendly composite packaging film, including a main packaging film 1, the number of the main packaging films 1 is set to two groups, and the middle of the two groups of main packaging films 1 are bonded together by hot melting; the main packaging film 1 is made of low-density polyethylene; a buffer film bubble 101 is integrated into the main packaging film 1, and the buffer film bubble 101 between the two groups of main packaging films 1 is filled with air; an aluminized film 2 is attached to the outside of the main packaging film 1; and a pyramid bin 201 is integrally provided on the outside of the aluminized film 2.

[0027] The buffer film bubble 101 of the primary packaging film 1 is aligned with the pyramid bin 201 .

[0028] The pyramid bin 201 and the buffer film bubble 101 are sealed and adhered to each other with environmentally friendly polyurethane glue in a vacuum environment.

[0029] A spacing zone is provided between the main packaging film 1 and the aluminized film 2 , and the buffer film bubble 101 and the pyramid bin 201 are not provided at the spacing zone.

[0030] The sides of the main packaging film 1 and the aluminized film 2 are both provided with docking holes 3 , and the docking holes 3 on the outside of the main packaging film 1 and the aluminized film 2 are aligned.

[0031] The docking hole 3 can be used to pass through and fix a rivet.

[0032] like Figure 1-4 As shown, when assembling the main packaging films 1, two sets of main packaging films 1 are pre-punched into cushioning film bubbles 101 using a device, and then the two sets of main packaging films 1 are attached together, and the cushioning film bubbles 101 are aligned up and down. The two sets of main packaging films 1 are fixed on their flat surfaces by hot-melt or with a sealant. Before hot-melt, the edges are sealed, and then air is injected into the middle to ensure that the cushioning film bubbles 101 are filled with air and bulge after hot-melt fixing.

[0033] After the two groups of main packaging films 1 are made into one group, the main packaging film 1 and the aluminized film 2 are installed in a vacuum environment, and the pyramidal bin 201 is aligned and installed on the outside of the buffer film bubble 101, and then sealed, or the three can be hot-melted at the same time to form a composite packaging film; the buffer film bubble 101 provides a buffering and shock-absorbing function, and the space between the buffer film bubble 101 and the pyramidal bin 201 provides a heat insulation effect, which can greatly reduce temperature transmission and provide a heat preservation effect.

[0034] Example 2:

[0035] On the basis of Example 1, Figure 5 As shown, after folding the main packaging film 1 and the aluminized film 2, rivets are passed through the docking holes 3, and rivet rings are used in conjunction with rivets to achieve fixation, thereby increasing the stress of the main packaging film 1 and ensuring that it forms a bag shape; or sutures are passed through the docking holes 3 to still achieve suture fixation.

[0036] The specific usage and function of this embodiment are as follows:

[0037] In the present invention, when assembling the main packaging films 1, two sets of main packaging films 1 are pre-punched out into buffer film bubbles 101 using a device, and then the two sets of main packaging films 1 are attached together, the buffer film bubbles 101 are aligned up and down, and the two sets of main packaging films 1 are fixed on their flat surfaces by hot-melt or by using a sealant. Before hot-melt, the edges are sealed, and then air is injected into the middle to ensure that the buffer film bubble 101 is filled with air and bulges after hot-melt fixing.

[0038] After the two sets of main packaging films 1 are assembled into one set, the main packaging films 1 and the aluminized film 2 are installed in a vacuum environment, and the pyramid bins 201 are aligned and installed on the outside of the buffer film bubble 101, and then sealed. Alternatively, the three can be heat-fused simultaneously to form a composite packaging film.

[0039] The buffer film bubble 101 provides a buffering and shock-absorbing function, and the space between the buffer film bubble 101 and the pyramid chamber 201 provides a heat-insulating effect, which can significantly reduce temperature transmission and provide a heat-insulating effect;

[0040] If you need to make packaging bags, follow Figure 5 After folding the main packaging film 1 and the aluminized film 2, rivets are passed through the docking holes 3, and rivet rings are used in conjunction with rivets to achieve fixation, thereby increasing the stress of the main packaging film 1 and ensuring that it forms a bag shape; or sutures are passed through the docking holes 3 to still achieve suture fixation.
