Problems solved by technology

[0005] 2. No vacuum tunnel effect and liquid accumulation;
[0010] However, the heat insulation effect of the existing vacuum skin packaging film is not good, the overall structural strength is not high enough, and its anti-counterfeiting performance is poor, so that the product levels of the vacuum skin packaging film on the market are not uniform, and cannot effectively meet the requirements of the vacuum environment. Industrial demand for packaging

Embodiment 1

[0035] Such as figure 1 As shown, this embodiment is a vacuum skin packaging film, which includes a surface layer 2, a first structure layer 4, a barrier layer 5, a second structure layer 6 and a heat-sealing layer 10 from top to bottom, and the surface layer 2 and the first structure layer A three-dimensional code layer 3 is arranged between the layers 4, and a three-dimensional code structure is arranged on the middle and upper part of the three-dimensional code layer 3, or the upper surface of the three-dimensional code layer 3 is printed with two-dimensional codes of useful colors and gray scales to represent the plane three-dimensional code information of the three-dimensional code. Code structure; the three-dimensional code structure can record product production information and anti-counterfeiting information, which greatly improves the anti-counterfeiting effect;

[0036] Between the second structural layer 6 and the heat-sealing layer 10, an inflatable thermal insulat...

Abstract

The invention relates to a vacuum skin packaging film. The vacuum skin packaging film comprises a surface layer, a first structural layer, a barrier layer, a second structural layer and a heat-sealinglayer from top to bottom, a three-dimensional code layer is arranged between the surface layer and the first structural layer, stereoscopic three-dimensional code structures are arranged at the middle-upper part of the three-dimensional code layer, or planar three-dimensional structures adopting two-dimensional codes of the color and the gray scale to represent three-dimensional information is printed in the upper surface of the three-dimensional code layer; and an inflating heat insulation layer and a third structural layer are also arranged between the second structural layer and the heat-sealing layer from top to bottom. The vacuum skin packaging film can effectively insulate heat, has a high structural strength, and has an excellent anti-counterfeiting effect due to the adoption of the three-dimensional code structures to record product information and anti-counterfeiting encryption information; and the vacuum skin packaging film has excellent sealing and heat-sealing effects, meets performance requirements of vacuum skin packaging, and has excellent market benefits.

Description

technical field [0001] The invention relates to a packaging film structure, in particular to a vacuum skin packaging film and a crosslinking treatment method thereof. Background technique [0002] Vacuum skin packaging is to place the packaged product on a special plastic sheet or film, so that the skin film covering the product is close to the surface of the product under the action of heating and vacuuming, and is sealed with the bottom film . Skin-packed products are well protected while displaying their natural form and appearance. [0003] When using VSP for food packaging, there are many irreplaceable advantages. [0004] 1. Excellent vacuum and skin tight protection, longer shelf life; [0005] 2. No vacuum tunnel effect and liquid accumulation; [0006] 3. Better packaging display effect, attracting attention; [0007] 4. Reduce frozen spots of frozen food; [0008] 5. It can be used to pack soft contents; [0009] 6. Vertical display, reducing display space a...
