Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the embodiments of the drawings.

[0040] The LDPE high-foaming composite aluminized film of this embodiment, such as figure 1 As shown, it includes an aluminized film 1, specifically a PET aluminized film, wherein a layer 3 of LDPE formed by high foaming is laminated on the aluminized film 1, that is, a pearl cotton layer, the aluminized film 1 and the sheet A PE adhesive layer 2 is arranged between the material layers 3, that is, the aluminized film 1 and the sheet material layer 3 are bonded together through the PE adhesive layer 2.

[0041] Among them, in order to make the LDPE high-foam composite aluminized film have better strength and shock resistance at the same time, the thickness ratio of the aluminized film 1, the PE adhesive layer 2 and the sheet layer 3 is 1:0.5:2.0. The thickness of the material layer 3 is 1.5 mm.

[0042] The PE adhesive layer used in this embodiment—PE film is...

Abstract

The invention discloses an LDPE (Low-Density Polyethylene) high-foamed composite aluminized film and a preparation method thereof. The LDPE high-foamed composite aluminized film comprises an aluminized film, wherein a sheet material layer which is formed by LDPE through high foaming is laminated above the aluminized film, and a PE (Polyethylene) binding layer is arranged between the aluminized film and the sheet material layer; the sheet material layer is prepared from the following ingredients in percentage by weight: 95% of LDPE, 3.5% of nucleating agent, 1.39% of foaming agent, 0.1% of anti-shrinking agent and 0.01% of auxiliary aids. Compared with the prior art, the LDPE high-foamed composite aluminized film disclosed by the invention has better shockproof, waterproof, dustproof, sunproof and moisture preserving effects, can be recycled and is environment-friendly, convenient and practical; furthermore, the LDPE high-foamed composite aluminized film disclosed by the invention is applicable to the industries of buildings, ice bags, moisturizing hand bags, cases/bags, sun-shading boards and the like.

Description

Technical field [0001] The invention relates to an aluminized film, in particular to a LDPE high-foaming composite aluminized film, and the invention also relates to a preparation method of an LDPE high-foaming composite aluminized film. Background technique [0002] EPS polystyrene has the disadvantages of fragile, deformed, and poor recovery when used. It cannot be recycled after use, causing environmental pollution. LDPE high-foaming material has many cushion packaging advantages. It does not produce three wastes during production and use, and can be recycled. Polluting the environment, it is a new type of environmental protection material. The market predicts that cushioning packaging materials will gradually be 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 abrasion resistant; they are easily damaged during transportation or during us...
