Abstract

The invention discloses a corrugated paper and a manufacturing method thereof. The corrugated paper is composed of the raw materials according to parts by weight: 45-60 parts of USA No.11 waste paper, 30-55 parts of EOCC and 10 parts of Chinese domestic high-grade carton paper. The technical scheme provided by the invention utilizes Chinese domestic high-grade waste carton paper, USA No.11 waste paper and EOCC as raw materials, thus not only ensuring the reuse of Chinese domestic high-grade waste carton paper, embodying circular economy, saving resources, and protecting environment; meanwhile, the strength of the corrugated paper is obviously improved, and the surface is fine and beautiful and is favourable for ensuring printing effect. All the technical links of the provided manufacture method do not have rigorous requirements, so that the manufacturing method is suitable for industrial production and can fully embody the technical effect of the corrugated paper.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, in particular relates to corrugated paper, and also relates to a manufacturing method of the corrugated paper. Background technique [0002] Corrugated paper is also customarily called corrugated cardboard. There are many reports on corrugated cardboard and corrugated cardboard manufacturing methods in the literature, especially Chinese patent documents. It is to put corrugated corrugated paper bonded together between two layers of cardboard paper, but neither the raw material (recipe) of corrugated paper nor the method of how to prepare corrugated paper is given, but it is made of ready-made corrugated paper. Four-layer corrugated paper. Publication No. CN101532270A recommends lightweight flexographic pre-printed color corrugated cardboard and its manufacturing method. This patent application scheme also belongs to the specific application of existing (ready-made) corrugated cardboa...
