Disposable compound environment-friendly packaging material

Abstract

The invention discloses a disposable compound environment-friendly packaging material and a preparation technology thereof and belongs to the field of compound packaging materials. The disposable compound environment-friendly packaging material is prepared from the following raw materials in parts by weight: 20-25 parts of wood fiber, 10-15 parts of bamboo fiber, 20-25 parts of polyglycol, 10-15 parts of polyvinyl alcohol, 15-20 parts of polylactic acid, 5-8 parts of foaming agent, 10-15 parts of solubilizer, 10-15 parts of plasticizer, 10-12 parts of alkyd resin, 10-12 parts of calcium phosphate, 8-10 parts of polytetrafluoroethylene, 11-15 parts of carboxyethyl cellulose and 2-10 parts of acrylic ester. The preparation technology for the disposable compound environment-friendly packagingmaterial comprises the following steps: S1) mixing a part of raw materials, thereby acquiring a solution A; S2) adding raw materials into the solution A and then mixing, thereby acquiring a solutionB; S3) mixing the residual raw materials with the solution B, thereby acquiring a solution C; S4) mixing the solution B and the solution C and then sizing. The packaging material provided by the invention is low in production cost and has high biodegradability. The molding method of the disposable compound environment-friendly packaging material is not unique.

Description

technical field [0001] The invention relates to the field of composite packaging materials, and more specifically relates to a disposable composite environment-friendly packaging material. [0002] The invention relates to the field of composite packaging materials, and more specifically, relates to a preparation process of a disposable composite environmental protection packaging material. Background technique [0003] On the basis of the development of the packaging industry, the packaging of articles has also been developed accordingly, from simple paper packaging to single-layer plastic film packaging, to the widespread use of composite materials, where composite materials refer to two or more materials. Combined together through one or more composite processes to form a composite material with certain functions, which can generally be divided into base layer, functional layer and heat-sealing layer.

[0003] On the basis of the development of the packaging industry, the packaging of articles has also been developed accordingly, from simple paper packaging to single-layer plastic film packaging, to the widespread use of composite materials, where composite materials refer to two or more materials. Combined together through one or more composite processes to form a composite material with certain functions, which can generally be divided into base layer, functional layer and heat-sealing layer. However, in the existing composite packaging materials and their preparation processes, the materials are not easy to degrade. In particular, once-use packaging materials are mixed in the soil and accumulated, which will affect the absorption of nutrients and water by crops, resulting in crop yield reduction and affecting agricultural development. At the same time, limited by materials, the preparation process is single, which greatly reduces output efficiency.
