Problems solved by technology

[0007] The disadvantage of the above-mentioned fruit bagging is that a variety of papers are used for the outer bag paper, the middle bag paper, and the inner bag paper respectively to make fruit bagging. Each layer of bags is independent of each other and can be separated, and there is a gap between each layer of bags

Embodiment 1

[0052] Use bleached softwood pulp and bleached hardwood pulp as the outer pulp, bleached softwood pulp and bleached wheat straw pulp as the middle layer, and bleached softwood pulp and hardwood pulp as the inner pulp to make a three-layer fruit bag Paper. The specific production steps are as follows:

[0053] 1. Production of the outer wet paper sheet

[0054] Dilute the mixed pulp of 30% bleached softwood pulp and 70% hardwood pulp with water to a mass concentration of 5%, and after dispersing evenly, add retention aid cationic starch, sizing agent alkyl ketene dimer emulsion, and strengthening agent Melamine formaldehyde resin, colorant direct apricot dye, for dispersion and mixing. After mixing evenly, it is further diluted to a pulp suspension with a mass concentration of 1%, and then filtered and molded to form an outer layer wet paper sheet to obtain a light yellow outer layer wet paper sheet.

[0055] The amount of cationic starch is 2% of the absolute dry pulp, the ...

Embodiment 2

[0071] The difference between embodiment 2 and embodiment 1 is that embodiment 2 uses oxidized starch as the interlayer adhesive of the three-layer fruit bagging paper.

[0072] The spraying amount of oxidized starch is 2g / m 2 .

[0073] The use method of the oxidized starch is as follows: firstly, the cationic starch is formulated to a mass concentration of 5%, and then gelatinized to obtain the gelatinized oxidized starch. Spray the gelatinized oxidized starch on the inner side of the outer layer wet paper sheet and the inner layer of the middle layer wet paper sheet respectively, then place the middle layer wet paper sheet on the outer layer wet paper sheet, so that the outer layer wet paper sheet is sprayed with adhesive The side of the wet paper sheet of the middle layer is laminated with the unsprayed adhesive side. Furthermore, the inner wet paper sheet is placed on the middle layer wet paper sheet, so that the adhesive side of the middle layer wet paper sheet is lami...

Embodiment 3

[0079] The difference between Example 3 and Example 1 is that the bleached softwood pulp and bleached hardwood pulp are used as the outer layer pulp, and the bleached softwood pulp and bleached wheat straw pulp are used as the inner layer pulp to make double-layer structure fruit bagging paper. The specific production steps are as follows:

[0080] 1. Production of the outer wet paper sheet

[0081] Dilute the mixed pulp of 30% bleached softwood pulp and 70% hardwood pulp with water to a mass concentration of 5%, and after dispersing evenly, add retention aid cationic starch, sizing agent alkyl ketene dimer emulsion, and reinforcing agent Melamine formaldehyde resin, colorant direct red dye, for dispersion and mixing. After mixing evenly, it is further diluted to a pulp suspension with a mass concentration of 1%, and then filtered and molded to form an outer layer wet paper sheet to obtain a light yellow outer layer wet paper sheet.

[0082] The amount of cationic starch is ...

Abstract

The invention belongs to the technical field of fruit cultivation bags, and relates to fruit cultivation bag paper with a multilayer compound structure, as well as a manufacturing method of the fruit cultivation bag paper. The paper achieves the compounding of multilayer structures, which means that the paper achieves the function of compounding multiple types of independent and separate paper in the prior art. The manufacturing method comprises the following steps: each wet paper sheet layer is respectively manufactured; all the wet paper sheet layers are then superposed, so as to form a wet paper sheet with a multilayer structure; the wet paper sheet with the multilayer structure is finally subjected to pressing dewatering and drying dewatering, so as to obtain the fruit cultivation bag paper with the multilayer structure. All the layers in the paper structure have different performance, so that the fruit cultivation bag paper achieves the effect of a double-layer or three-layer fruit cultivation bag manufactured from the multiple types of paper.

Description

technical field [0001] The invention relates to a fruit bagging paper, in particular to a fruit bagging paper with a multi-layer composite structure and a manufacturing method thereof, belonging to the technical field of fruit bagging. Background technique [0002] With the improvement of people's living standards, people's requirements for fruits are turning to high-quality and pollution-free green fruits. The price of commercially available pollution-free fruits is significantly higher than that of ordinary fruits, and the production of pollution-free fruits depends on whether fruit bagging technology is applied. . [0003] Fruit bagging technology is to use the method of fruit bagging in the process of fruit growth, instead of the traditional method of spraying pesticides, so that the fruit in the bag will not be attacked by birds or fruit fly bacteria Infection will not be scratched by the branches, and the fruit can avoid direct sunlight, and because the air permeabili...
