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
The present invention relates to a kind of fruit inspecting, particularly relate to and there is multi-layer compound structure fruit inspecting and preparation method thereof, belong to fruit bagging technology field.
Background technology
Along with the raising of people's living standard, the requirement of people to fruit turns to the green fruit of high-quality and Harmless, and commercially available Pollution-free Fruit price is apparently higher than common fruit, and the production of Pollution-free Fruit depends on whether apply fruit bagging technology.
Fruit bagging technology is in the process of fruit growing, adopt the way of fruit bag, instead of spray traditionally and shine the method for agricultural chemicals, make the fruit in bagging can not be subject to the infringement of birds, the infection of fruit bat bacterium can not be subject to, also can not by branch scratch, and make fruit avoid the direct irradiation of sunlight, more because the gas permeability of bagging itself can produce indivedual greenhouse effects, make humidity, temperature that fruit keeps suitable, improve the sugariness of fruit, improve the gloss of fruit, increase fruited output, and shorten its growth stage.In addition, do not need applying pesticides in the process due to growth, make fruit have high-quality and nuisanceless, meet the demand for development of green non-pollution agricultural.
Fruit bag is divided into single ply bag, double-ply bag and three layers of bag.Usually, double-ply bag, three layers of bag are better than single ply bag to the effect of promoting fruit appearance and quality, but are separate discerptible between each layer bag.
At present, more Study and appliance mainly concentrates on: make and select the internal layer of applicable fruit bag, intermediate layer, outer field paper respectively, namely inner bag paper, middle bag paper, outer bag paper, then carry out combination and make fruit bag, has plenty of double-ply bag, have plenty of three layers of bag, be separate discerptible between each layer bag, and have space.Such as, the mcintosh kind based on Fuji apple, is applicable to selecting double-ply bag black in outer ash.This double-ply bag, outer what select is the paper of grey, the paper of what internal layer was selected is black.Pear varieties based on water-rich areas, the inner bag black mainly selecting light-proofness stronger, the cervine double-ply bag of outer bag.The paper that pears bagging is selected is, what outer bag was selected is lurid paper, the paper of what inner layer bag was selected is black.
The method of the double-deck bagging of this making; adopt two kinds of paper with different performance; a kind of for making inner bag; a kind of for making outer bag; play two kinds of paper performances and effect; reach in protection fruit developmental process, effectively reduce fruit disease and pest, stop the residues of pesticides on fruit face and improve fruit quality.
The shortcoming of above-mentioned fruit bag is that multiple paper is respectively used to outer bag paper, intermediate bag paper, inner layer bag paper, makes fruit bag, and each layer bag is separate separately, has space between each layer bag.The present invention is directed to this shortcoming, make a kind of fruit inspecting, this paper has sandwich construction, every one deck of this paper has different performances, directly can make fruit bag with this paper, object and the effect of fruit Multi-layer bag can be reached, can be used as the paper making fruit bag, in other words be that separable multilayer bag of the prior art is combined into a piece of paper plate, form overall inseparable sandwich construction.
Summary of the invention
The object of the invention is the shortcoming being to overcome prior art, provide a kind of fruit inspecting, this paper a kind ofly has the paper that sandwich construction is combined with each other into, be equivalent to the function and service of the multiple paper of independent separate of the prior art on a piece of paper is opened, every layer in this paper structure has different performances, can reach the effect of the double-deck bagging of the fruit using multiple paper to make, three layers of bagging.
Meanwhile, another object of the present invention there is provided the preparation method of this fruit inspecting, and the application that fruit inspecting is grown up in protection at fruit.
The fruit bag that this fruit inspecting makes, has double-decker and to be combined with each other the effect of fruit bag that fruit bag or three-decker be combined with each other, meet fruit and grow up and protection fruit quality, ensure the greenization of Production of fruit.
Multi-layer compound structure fruit inspecting of the present invention, is characterized in that, fruit inspecting is two-layer or being combined with each other of fitting tightly of three-decker, every one deck be quantitatively 10g/m
2~ 42g/m
2, thickness is 0.036mm ~ 0.081mm, and the total of fruit inspecting is quantitatively 30g/m
2~ 82g/m

Preferably have double-deck fruit inspecting, the quantitative of every one deck is 20g/m
2~ 42g/m
2, thickness is 0.036mm ~ 0.081mm, and the total of fruit inspecting is quantitatively 40g/m
2~ 82g/m
2, gross thickness is 0.072mm ~ 0.14mm.
Have the fruit inspecting of three-decker, preferably every one deck is quantitatively 10g/m
2~ 42g/m
2, thickness is 0.036mm ~ 0.081mm, and the total of fruit inspecting is quantitatively 40g/m
2~ 82g/m
2, gross thickness is 0.072mm ~ 0.14mm.
The preparation method of sandwich construction fruit inspecting of the present invention, is characterized in that, is to make every one deck l Water Paper page respectively, and as do not made outer l Water Paper page, middle level l Water Paper page, internal layer l Water Paper page, every layer of l Water Paper has different performances.Then, each layer l Water Paper page is superimposed together, forms sandwich construction l Water Paper page.Finally, after press dewatering, drying and dehydrating are carried out to sandwich construction l Water Paper page, sandwich construction fruit inspecting is obtained.
Above-mentioned double-decker fruit inspecting or the preparation method of three-decker fruit inspecting, comprise following steps:
