Example Embodiment

[0027] The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.

[0028] The LDPE high-foaming composite HDPE film of the present embodiment, such as figure 1 As shown, HDPE film 1 is included, wherein, the surface of HDPE film 1 is provided with a sheet layer 3 formed by high foaming of LDPE, and a PE adhesive layer 2 is provided between HDPE film 1 and sheet layer 3, that is, HDPE film 1 and sheet layer 3 are bonded together by PE adhesive layer 2.

[0029] Among them, in order to make the LDPE high-foaming composite HDPE film have good strength and shock resistance at the same time, the thickness ratio of the HDPE film 1, the PE adhesive layer 2 and the sheet layer 3 is 1:0.2:0.8, wherein the sheet layer 3 has a thickness of 1.0mm.

[0030] The PE adhesive layer used in this example, the PE film, is a film made by heating and melting PE plastic particles. The advantages of the PE film are: low cost, so...

Abstract

The invention discloses an HDPE(high-density polyethylene) membrane composited by high foaming of LDPE(Low-Density Polyethylene) and a preparation method of the membrane. The HDPE membrane composited by the high foaming of the LDPE comprises the HDPE membrane, wherein a sheet layer formed by the high foaming of the LDPE is arranged on the surface of the HDPE membrane, and a PE(Poly Ethylene) bonding layer is arranged between the HDPE membrane and the sheet layer; the sheet layer consists of the following components in percentage by weight: 95% of the LDPE, 3.5% of a nucleating agent, 1.39% of a foaming agent, 0.1% of an antisbrinking agent and 0.01% of an auxiliary addition agent. Compared with the prior art, the HDPE membrane composited by the high foaming of the LDPE is a novel environmental-friendly packaging material with high buffering capacity and shock resistant capacity, the membrane has the advantages that the flexibleness and the buffering capacity are good, the heat conductivity is low, the heat-shielding performance is excellent, the membrane does not pollute the environment, and the membrane belongs to the materials capable of being recycled.

Description

technical field [0001] The invention relates to an HDPE film, in particular to an LDPE high-foaming composite HDPE film, and the invention also relates to a preparation method of the LDPE high-foaming composite HDPE film. Background technique [0002] EPS polystyrene has the disadvantages of brittleness, deformation and poor recovery when used. It cannot be recycled after use, causing environmental pollution. However, LDPE high-foaming materials have many advantages of buffer packaging. They do not produce three wastes during production and use, and they are recyclable and non-toxic. It pollutes the environment and belongs to new environmentally friendly materials. The market predicts that the buffer packaging materials will be gradually replaced by LDPE high foam packaging materials. [0003] However, when LDPE high foam packaging materials are used to package various products, their tensile strength is low and they are not wear-resistant; they are easily damaged during tr...
