Abstract

The invention discloses a method for producing outer bag paper of apple fruit growing bags by coating method, which comprises pulping, pulping, net part forming, pressing and dehydration, paint preparation, coating, drying, coiling, slitting and rewinding to obtain finished products. The apple fruit bag paper produced by the invention can be divided into base paper and coating. The light-shielding property is completed by the pigment coating containing carbon black. It has the advantages of simple production process, low cost, and less pollution. It also solves the problem of In the layering method, carbon black is used for dyeing in pulp, which causes pollution and low utilization rate. Using carbon black and porcelain clay mixed paint for low-quantity coating can obtain good light-absorbing performance and is not easy to fall off black, maintain high softness and air permeability, high carbon black utilization rate, less usage, and water resistance meet the use requirements. The invention can be used to produce the outer bag paper of the apple fruit-raising bag, can meet the growth requirement of the fruit, prevents the pollution of pesticides and the erosion of wind and rain, and enhances the color and luster of the fruit surface.

Description

technical field [0001] The invention relates to a method for manufacturing an outer bag paper of an apple fruit-raising bag, in particular to a method for producing the outer bag paper of an apple fruit-raising bag by coating. Background technique [0002] With the improvement of people's living standards and the enhancement of environmental protection awareness, the demand for fruits is increasing, and higher requirements are also put forward for their quality. Natural and pollution-free green fruits are becoming more and more popular. Fruit bag paper is a kind of agricultural technical paper used in the process of fruit growth in order to improve the quality of fruit products and increase its economic value. The use of fruit bagging can improve the coloring degree of the fruit, and it is entirely possible to achieve full red fruit; it can improve the cleanliness of the fruit, reduce the residue of pesticides and dust pollution, and ensure human health; improve the integrit...
