Problems solved by technology

[0003] With the continuous development of electronic information technology, the volume of some electronic components is getting smaller and smaller. In order to ensure their quality and performance, heat shrinkable film is used to align Venus for independent packaging, but since heat shrinkable film is close-fitting packaging and electronic The volume of the components is small. When peeling off the heat shrinkable film of the outer packaging of the electronic components before use, it is difficult to peel off. If you do not pay attention to the excessive peeling force, it will cause damage to the electronic components and affect the normal use of the electronic components.

Embodiment 1

[0051] see Figure 1-10 , a self-peeling type heat shrinkable film, including a body, the body includes an antistatic base layer 1 on the lower side, a protective guiding friction layer 3 on the upper side, and an antistatic base layer 1 and the protective guiding friction layer 3. The flower-type shrinkage peeling layer 2, the flower-type shrinkage peeling layer 2 is respectively connected with the antistatic base layer 1 and the protective guiding friction layer 3, and a plurality of self-peeling anti-flowering films are arranged in the flower-type shrinkage peeling layer 2; please refer to figure 1 , the self-peeling anti-flower film includes a stamen conductive cylinder 4, and the outer end of the stamen conductive cylinder 4 is fixedly connected with a plurality of olive-shaped stripped petals 5 distributed in a circle, and the upper and lower ends of the olive-shaped stripped petals 5 are far away from the stamen conductive cylinder 4 One side is fixedly connected with a...

Embodiment 2

[0063] see Figure 1-10 , where the same or corresponding components as those in Embodiment 1 use the corresponding reference numerals as in Embodiment 1, and for the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this embodiment 2 and embodiment 1 is: please refer to figure 2 , a preparation process of a self-peeling type heat-shrinkable film, comprising the steps of:

[0064] S1. Pre-production: pre-prepared self-peeling anti-blossom film, and combined it according to a certain arrangement to make flower-shaped shrinkage peeling layer 2;

[0065]S2. Primary film lamination: when the antistatic base layer 1 is prepared by blowing, the flower-shaped shrinkable release layer 2 obtained in step S1 is melted and blown together in advance to obtain the antistatic base layer 1 attached with the flower-shaped shrinkable release layer 2;

[0066] S3. Secondary film lamination: add the antistatic base layer 1 obtained in s...

Abstract

The invention discloses a self-stripping type heat shrinkage film and a preparation process thereof, which belong to the field of heat shrinkage films. The self-stripping type heat shrinkage film comprises a body; the body comprises an anti-static base layer located on the lower side, a protection guiding friction layer located on the upper side and a flower type shrinkage stripping layer arranged between the anti-static base layer and the protection guiding friction layer, and the flower type shrinkage stripping layer is connected with the anti-static base layer and the protection guiding friction layer. By applying a weak voltage to the friction line of different materials, the olive-shaped stripping petals are shrunk under the action of external voltage, so that the body is broken, self-stripping of the thermal shrinkage film is completed, the stripping efficiency of the thermal shrinkage film is improved, the stripping difficulty of the thermal shrinkage film is reduced, and damage to an electronic element during stripping of an outer package is reduced; and the size of the electrostatic voltage generated in the storage and transportation process of the electronic component is effectively tested, so that the packaging is convenient to improve, and the quality of the electronic component is improved.

Description

technical field [0001] The invention relates to the field of heat-shrinkable films, in particular to a self-peeling heat-shrinkable film and a preparation process thereof. Background technique [0002] Heat shrinkable film is widely used in the outer packaging of various products such as food, medicine, disinfection tableware, cultural and sports supplies, craft gifts, printed matter, metal and plastic products, telephones, electronic appliances, etc. In terms of combined (cluster) packaging, it can not only meet the functions of moisture-proof and dust-proof, touch-proof, transparent display, etc., but also increase the attractiveness of the product appearance. It can also be used to replace various cartons, which not only saves packaging costs, but also In line with packaging trends. Shrink film (bag) can be processed into special-shaped bags such as flat bags, arc-shaped bags, trapezoidal bags, and three-dimensional bags [0003] With the continuous development of elect...
