Degradable sealed damp-proof environment-friendly package and preparation method thereof

Abstract

The invention discloses a degradable sealed damp-proof environment-friendly package and a preparation method thereof. The preparation method comprises the following steps: washing and drying natural bamboo, ramie fiber, straw, wheat straw and waste paper boards which serve as raw materials, placing the washed raw materials in a crusher, and crushing; adding polylactic acid fiber, methyl methacrylate, dibutyl phthalate and hexamethylphosphoric triamide into the slurry, pouring into the slurry, adding water into the crushed raw materials, mixing and stirring in a stirrer to form slurry, and cooling and storing; placing the slurry in a compression molding machine, performing compression treatment, and pressing the slurry into a single-layer paperboard in a board making machine; and sequentially dividing the manufactured single-layer paperboard into a bottom layer, a middle layer and a top layer, and attaching degradable high-toughness fiber nets to the two sides of the outer surface of the middle layer through an adhesive. The package and the preparation method thereof have the beneficial effects that the raw materials are easily available, the operation is simple, the cost is low, the method is economical and environment-friendly, the problems of contradiction between environment-friendly packaging and environment protection and the like are fully solved, and the finished paper is high in strength, good in toughness, not easy to break and wide in application range.

Description

technical field [0001] The invention relates to the technical field of environmental protection packaging, in particular to a degradable sealed moisture-proof environmental protection packaging and a preparation method. Background technique [0002] As an indispensable part of modern logistics, packaging cartons bear important responsibilities for packaging, product protection, and aesthetics. The physical performance indicators of packaging cartons become the basis for their quality evaluation. Generally, packaging cardboard cannot be reused many times. The plastic components on the surface of packaging cardboard will take a long time to age, which will lead to plastic pollution and cause great harm to human body and environment. Cartons are easily eroded by external moisture during transportation, and wrinkles are prone to appear in the moisture eroded parts, resulting in more breakage, which reduces the protection effect of the carton on the items.
