Embodiment 1

[0020] Refer to attached figure 1 As shown, the EPE sheet used in the prior art is directly cut, which has multiple cutting planes, and the particles of the EPE layer in the middle will fall out through the unclosed cutting planes and fall into the wrapped instruments and parts In and attached to it, it will affect the performance of the wrapped object, reduce its accuracy, and even cause damage to it.

[0021] It is made of polyethylene (PE) after foaming, and the EPE sheet is also called pearl cotton. During the processing of the EPE sheet, a layer of PE film is formed on the surface.

[0022] Refer to attached figure 2 As shown, an edge-sealing EPE sheet of the present invention includes a first PE film layer 1, a second PE film layer 2 and an EPE layer between the first PE film layer 1 and the second PE film layer 2 3. The edge of the first PE film layer 1 and the second PE film layer 2 is fixedly connected, and a closed space for storing the EPE layer 3 is form...

Abstract

The invention relates to an edge sealed EPE (electronic parts and equipment) sheet and a preparation method thereof. The preparation method comprises the following steps of: carrying out edge sealing on the EPE sheet through hot pressure, wherein the EPE sheet is provided with a first PE film layer, a second PE film layer and an EPE layer arranged between the first PE film layer and the second PE film layer; fixedly connecting the edges of the first PE film layer and the second PE film layer through the hot pressure, and sealing the EPE layer in an airtight space formed between the first PE film layer and the second PE film layer. By the edge sealed EPE sheet and the preparation method thereof, particles in an EPE can be prevented from going out; and the edge sealed EPE sheet can be used in precision electronic components and instruments.

Description

technical field [0001] The invention relates to an EPE sheet and a preparation method thereof. Background technique [0002] Because it has many advantages such as water and moisture resistance, shock resistance, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance, etc., it also has good chemical resistance, and is widely used in packaging and filling materials aspect. In actual use, most of the cut EPE sheets are directly used for packaging. The cut EPE sheet has a cutting plane, and some particles in the EPE will fall out of the cutting plane. In the packaging of some precision electronic instruments and parts that require high precision, the particles falling out of the EPE sheet are likely to fall into the wrapped instruments and parts and adhere to them, affecting the performance of the wrapped objects. reduce its accuracy, or even damage it. Contents of the invention [0003] In vie...
