Description

Technical Field

[0001] This utility model relates to the field of packaging material technology, specifically to a high-barrier, easy-open PP film cover. Background Technology

[0002] High-barrier easy-open PP film caps are packaging materials with high barrier properties and easy-open functionality. They are commonly used in packaging fields that require high barrier properties and convenient opening, such as food, pharmaceuticals, and electronic products.

[0003] Existing high-barrier PP film covers, through special processes such as pre-cut lines and easy-peel layers, make the PP film covers easy to open and convenient for users. However, based on daily use, it has been found that some high-barrier PP film covers have a problem of slipping when opened. That is, when pulling and peeling, due to the high adhesiveness of the film cover, it slips off when pulled or peels off, or the pulling end tears off.

[0004] Therefore, in view of the above-mentioned problems, this technical solution proposes a high-barrier, easy-to-open PP film cover. Utility Model Content

[0005] The purpose of this invention is to provide a high-barrier, easy-to-open PP film cover to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-barrier easy-open PP film cover, comprising a film cover bonded to the top of a film cover adhesive body, a PP substrate disposed in the center of the film cover, and barrier layers disposed on both sides of the PP substrate, wherein an easy-open layer is disposed on the outer side of the barrier layer facing the film cover adhesive body, and two easy-open blocks are symmetrically disposed on both sides of the film cover. The film cover is peeled off from the film cover adhesive body by pulling the easy-open blocks. One easy-open block has a corrugated strip at the bottom to increase the contact friction with the hand, thereby reducing the slippage between the hand and the easy-open block when pulling it off, i.e., improving the ease of opening. The other easy-open block has a piercing element at the bottom. When the hand pulls the easy-open block upward to open the film cover, it presses the piercing element and controls the piercing element to insert towards the opening between the film cover and the film cover adhesive body, piercing the adhesive joint between the film cover and the film cover adhesive body, thereby reducing the resistance when pulling the easy-open block.

[0007] As a further embodiment of this utility model: the puncture component includes a strip-shaped airbag disposed at the bottom of the easy-open block and distributed perpendicularly to the easy-connection point. The end of the strip-shaped airbag facing the easy-connection point is provided with an easy-break layer. The end of the strip-shaped airbag away from the easy-break layer is connected to a pressing airbag disposed at the bottom of the easy-open block through a connecting net. A set of plastic cones is disposed inside the strip-shaped airbag along its length direction. The end of the plastic cones facing the connecting net is connected to a pneumatic block.

[0008] As a further embodiment of this utility model, the PP substrate, barrier layer, and easy-to-remove layer are formed by thermoforming or calendering.

[0009] As a further embodiment of this invention, the surface of the membrane cover is subjected to printing and coating treatment.

[0010] As a further embodiment of this invention: the end of the strip-shaped airbag facing the fragile layer is configured as a pointed structure.

[0011] As a further improvement of this utility model, the strip-shaped airbag and the compression airbag are made of nylon, polyester fiber or silicone-coated fabric.

[0012] Compared with the prior art, the beneficial effects of this utility model are: by combining the PP substrate with the barrier layer, this membrane cover can effectively improve the oxygen barrier, moisture barrier and light barrier properties, thus fully improving the overall barrier properties. At the same time, by using the corrugated strips and puncture parts, the ease of opening is greatly improved. Attached Figure Description

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6 A high-barrier, easy-open PP film cover includes a film cover 11 bonded to the top of a film cover adhesive body 10. A PP substrate 20 is disposed in the center of the film cover 11, and barrier layers 21 are compositely disposed on both sides of the PP substrate 20. An easy-open layer 22 is disposed on the outer side of the barrier layer 21 facing the film cover adhesive body 10. Two easy-open blocks 12 are symmetrically disposed on both sides of the film cover 11. The film cover 11 is peeled off from the film cover adhesive body 10 by pulling the easy-open blocks 12. One of the easy-open blocks 12 has a corrugated bottom. The corrugated strip 13 increases the contact friction with the hand, thereby reducing the slippage between the hand and the easy-open block 12 when pulling it open, thus improving the ease of opening. On the other side, the bottom of the easy-open block 12 is provided with a piercing element. When the hand pulls the easy-open block 12 upward to open the film cover 11, it presses the piercing element and controls the piercing element to insert into the opening between the film cover 11 and the film cover adhesive body 10, piercing the adhesive joint between the film cover 11 and the film cover adhesive body 10, thereby reducing the resistance when pulling the easy-open block 12.

[0025] Specifically, the puncture component includes strip-shaped airbags 14 distributed perpendicularly to the easy-connect point at the bottom of the easy-open block 12. An easy-break layer 17 is provided at the end of the strip-shaped airbag 14 facing the easy-connect point. The end of the strip-shaped airbag 14 away from the easy-break layer 17 is connected via a connecting mesh 19 to a pressing airbag 15 located at the bottom of the easy-open block 12. Inside the strip-shaped airbag 14, along its length, is a set of plastic cones 16. An air-push block 18 is connected to the end of the plastic cones 16 facing the connecting mesh 19. In the non-use state... The strip-shaped airbag 14 and the pressing airbag 15 are filled with sufficient gas to keep them in an inflated state. When the easy-open block 12 is pulled to open the membrane cover 11, the hand simultaneously presses the pressing airbag 15. By forcing the air pressure in the pressing airbag 15 into the strip-shaped airbag 14, the air pusher block 18 is pushed, controlling the tip of the plastic cone 16 to pierce the easy-break layer 17 and move towards the easy-open area. Then, in conjunction with the pulling of the easy-open block 12, the membrane cover 11 is quickly opened.

[0026] In this embodiment of the invention, the PP substrate 20, the barrier layer 21, and the easy-to-peel layer 22 are thermoformed or calendered to form the composite material into a film cover shape; at the same time, printing and coating treatments are performed on the surface of the film cover 11 as needed to increase aesthetics and functionality.

[0027] The end of the strip-shaped airbag 14 facing the vulnerable layer 17 is designed with a pointed structure, which facilitates the rapid puncture of the vulnerable layer 17 under the push of the connecting net 19.

[0028] In one embodiment of the present invention, the strip airbag 14 and the compression airbag 15 are generally made of nylon, polyester fiber or silicone coated fabric.

[0029] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
