Problems solved by technology

[0006] The present application provides a packaging composite material layer, a packaging container and a manufacturing method of the packaging composite material layer, so as to solve the problem that the materials of the existing packaging composite material layer usually come from non-renewable resources such as non-renewable petroleum or fossil fuels, As a result, the greenhouse effect will be aggravated, and when crops are used as the source of the material, it will also lead to changes in the physical structure of the soil and soil acidification, and will prevent the growth of plant roots and decrease soil fertility. The local agricultural structure is unreasonable, The reduction of forest area affects the local economy and ecological rationality

Abstract

The invention provides a packaging composite material layer, a packaging container and a manufacturing method of the packaging composite material layer, the packaging composite material layer is usedfor packaging liquid food, and the packaging composite material layer comprises an outer layer, a paper layer and a composite layer which are sequentially laminated, wherein the outer layer and the composite layer are made of renewable polyethylene extracted from tall oil and / or grease. According to the present invention, the packaging composite material layer is prepared from the renewable polyethylene extracted from the tall oil and / or the grease so as to effectively reduce the emission of the greenhouse gas, and the packaging composite material layer is prepared by using the renewable resource, land, water and air with high biodiversity value and high carbon reserve can be effectively protected, and sustainable development of environment, society and economy can be promoted in a globalsupply chain.

Description

technical field [0001] The present application relates to the technical field of food packaging, in particular to a packaging composite material layer, a packaging container and a method for manufacturing the packaging composite material layer. Background technique [0002] With the economic development of human society and the increasing attention to the safety of food and beverages, liquid foods such as milk and beverages have been widely packaged with aseptic liquid packaging materials. [0003] However, from the perspective of materials, traditional aseptic liquid packaging is composed of polyethylene, paper, aluminum foil, etc., and the raw material of polyethylene is basically obtained by refining naphtha, a cracked product of petroleum. Therefore, this kind of polyethylene is also called petroleum-based polyethylene, which is neither derived from biological sources nor renewable resources, but relies on scarce petroleum, and petroleum-based, fossil fuel-based substrat...
