Problems solved by technology

In addition to protecting the product, facilitating storage and transportation, it also plays the role of beautifying the product and promoting the product; however, the existing corrugated box production has certain disadvantages in use, and it has not been collected and recycled repeatedly during the production process of the corrugated box Disinfection of raw materials may lead to contamination of corrugated boxes. When it is necessary to package food or mail baby products, it may lead to contamination of mailed items. At the same time, corrugated boxes will be waterproofed during production, but most manufacturers are in production. The waterproof layer is only coated on the outer surface of the carton, which makes the waterproof effect not very ideal and brings inconvenience to the subsequent use. Therefore, we propose an energy-saving and environmentally friendly corrugated carton production process

Abstract

The invention discloses an energy-saving and environment-friendly production process of corrugated cartons. The process comprises the following steps: treating raw materials, namely, sterilizing collected straws, waste newspapers, wheat straws and wood and bamboo poles, injecting water for soaking the raw materials after sterilization, then sequentially putting the raw materials into a pulverizer for pulverizing, and removing impurities to obtain pulp for later use, so that fiber pulp is obtained; and carrying out pulping and pulp mixing treatment on the obtained fiber pulp, namely, pulping fibers in the fiber pulp, then carrying out pulp mixing to obtain evenly mixed pulp, and carrying out standing for 100-120 min, wherein the concentration of the pulp is 3% to 5%, and thus the mixed paper pulp is obtained. According to the energy-saving and environment-friendly production process of corrugated cartons, the straws, the waste newspapers, the wheat straws and the wood and bamboo poles are collected from the raw materials, so that green and environment protection in the real sense are achieved, meanwhile, the inner sides and the outer sides of the corrugated cartons are coated with waterproof coatings, so that the service lives of the corrugated cartons are prolonged, and the waterproof effect is good.

Description

technical field [0001] The invention belongs to the technical processing field of cartons, in particular to an energy-saving and environment-friendly corrugated carton production process. Background technique [0002] Packaging carton is the most widely used product in the packaging industry. The production of corrugated cardboard used in my country is made of corrugated paper processed by corrugating rollers. It is light, firm, vibration-reducing and suitable for mechanized production. It has been used for many years. For transport packaging and sales packaging. Corrugated boxes have won the market for their exquisite appearance and inner good quality. In addition to protecting the product, facilitating storage and transportation, it also plays the role of beautifying the product and promoting the product; however, the existing corrugated box production has certain disadvantages in use, and it has not been collected and recycled repeatedly during the production process of t...
