Embodiment Construction

[0017] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0018] Embodiments of the invention include:

[0019] A double-sided aluminum-coated composite material, comprising: an intermediate layer, an upper aluminum-coated film deposited on the upper surface of the intermediate layer through vacuum evaporation, and a lower aluminum-coated film deposited on the lower surface of the intermediate layer through vacuum evaporation, the The middle layer is made of pearl cotton and non-woven fabric, wherein the mass fraction ratio of the pearl cotton to the non-woven fabric is 35-40:60-65. In this embodiment, the pearl cotton The mass fraction ratio with the non-woven fabric is: 36:64.

[0020] The thickness of the upper layer of aluminized film and the lowe...

Abstract

The present invention discloses a double-sided aluminum plating composite material, which comprises a middle layer, an upper layer aluminum plating film plated on the upper surface of the middle layer in a vacuum evaporation plating manner, and a lower layer aluminum plating film plated on the lower surface of the middle layer in a vacuum evaporation plating manner, wherein the middle layer is formed by compounding expandable polyethylene and a non-woven fabric according to a mass ratio of 35-40:60-65. With the technical scheme of the present invention, the barrier property, the stability and the mechanical protection property of the material can be improved, and the damage can be avoided.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to a double-sided aluminized composite material. Background technique [0002] The protection of packaging materials to the quality of the contents is one of the main functions of packaging, and the inner packaging plays a vital role in the protection of goods. [0003] Aluminized film is a composite flexible packaging material formed by coating a layer of extremely thin metallic aluminum on the surface of a plastic film using a special process. The most commonly used processing method is the vacuum evaporation aluminum method, which is passed through The high temperature melts and evaporates the metal aluminum, so that the aluminum vapor deposits and accumulates on the surface of the plastic film, so that the surface of the plastic film has a metallic luster. Because it has both the characteristics of plastic film and metal, it is a cheap and beautiful packaging material with ex...
