Abstract

The invention relates to a processing process of a packaging material, and discloses a process for preparing a bamboo rib reinforced composite packaging material by utilizing waste paper and bamboo. The processing process comprises the following steps of: (1) preparing a paperboard, that is to say, pretreating the waste paper, preparing mixed paper pulp and forming the paper board; (2) preparing a bamboo rib reinforcing plate, that is to say, pretreating the waste paper, preparing the mixed paper pulp, preparing the bamboo rib and forming the bamboo rib reinforcing plate; and (3) processing a single-layer composite board or a dual-layer closed board. The packaging material, prepared by the invention, has the advantages of environmental friendliness and degradable property, and a product has the advantages of high intensity, high hardness, good toughness and wear resistance.

Description

technical field [0001] The invention relates to a packaging material processing technology, in particular to a composite packaging material reinforced with bamboo ribs prepared from waste paper and bamboo. Background technique [0002] A large amount of waste paper comes from our daily life, such as household appliances, consumer food, electronic products, and leftover waste paper from the packaging and printing industry. my country's waste paper recycling technology started relatively late, and the method is relatively single. Some waste paper is recycled as raw materials for papermaking, and some are used to make simple and rough low-end products such as fruit trays and egg trays. Recycling technology has not been more effectively and widely applied in industrial product packaging and food packaging, and application technology has not made further breakthroughs. There are very few leading enterprises that can drive the industrialization of waste paper recycling. [0003] I...
