Description

{A PAPER BAG FOR FRUIT CULTURE}

The present invention relates to a bag for fruit cultivation, and more particularly, to a fruit cultivation bag which protects the fruit grown in the fruit water of the orchard from the surrounding natural environment and promotes the growth of the fruit.

Generally, the bag for fruit cultivation is a kind of cover which is used in fruit orchards to prevent the damage from pesticides, pests, and the natural environment which improves the coloring of the perilla during the growing period and adversely affects fruit in the orchard farm.

The fruit-cultivating bag covered by the fruit is covered with the fruit before the fruit is made to be made, so that the skin of the fruit is not directly exposed to the outside, preventing the discoloration of the fruit due to ultraviolet rays, It is widely used because it can protect fruit from birds such as shrike.

According to the Korean public utility model 2000-0005866 (tricolor tricolor colored bag for prevention of algae) used in such a manner, the cover is made of a transparent or silver foil cloth, the stop is made of black cloth or newspaper paper, And the color fabric of the inlay is differently applied according to the fruits to improve the meat quality of the fruit, and the cuticle of the fruit is made clear and sharp, and the fruit To prevent the damage of typhoons and algae by preventing damage to crops, to prevent penetration of pesticides into fruit and to maintain freshness at the time of shipment of fruit, However, since the bag is formed in triple, the entire thickness of the bag is thick, so that it is easy to cover the bag It takes a long time to work and the permeability of the inside of the bag is not smooth due to the triple bond of the cover, the stop and the inlay, and the transparency is high so that the inner temperature of the bag is raised, It was not evenly grown, but had a problem on the epidermis of the fruit where the epidermis became rugged or stained.

According to Korean Patent No. 10-0333022 (Fruit Seal) and Korean Registered Patent No. 10-0459150 (Fruit Seal), in order to solve the above problem, a bag for fruit cultivation is formed into a double layer by covering and inlay, The surface and the inward surface of the cover are surface treated with a surface treatment method of polyethylen wax and petroleum resin in order to control the water repellency, air permeability and moisture permeability, thereby preventing the moisture of rainwater or the like from penetrating from the outside to the cover, So that the moisture does not adhere to the fruit skin by discharging the moisture due to the evaporation action of the fruit and also has the air permeability so that the hot and humid heat inside the bag is inlaid with the cover, So that the fruit skin is evenly distributed due to the high temperature and humidity The skin was not to be prevented from being uneven or the dirt.

However, the conventional fruit cultivation bag described above always keeps the moisture and humidity in the bag at an appropriate level, thereby preventing the burning of the fruit, making the fruit surface (perilla) look good, and producing the fruit with excellent sugar content. However, It is difficult to maintain the color of fruits and to ship them earlier than the harvest time.

In order to solve the above problems, it is an object of the present invention to provide a bag which is covered with fruit and which promotes the growth of the fruit is formed in a single layer so that the production cost of the bag can be greatly reduced and the bag- To greatly reduce the time and cost of the work.

Another object of the present invention is to provide a method for improving the coloring of the fruit skin and improving the coloring and growth of the fruit by improving the water repellency and light shielding property of the pesticide, There is.

Means for Solving the Problems According to the present invention, there is provided a bag for fruit cultivation,
A bag for fruit cultivation, characterized in that a front surface is formed of a white paper having a high water resistance of 25 (SSR) and a black paper having a high water resistance of 60 to 70 (SSR), and the weight ratio between the white paper and the black paper 3: 2 ratio, and the black color is composed of 80 to 90 wt% of pulp, 5 to 10 wt% of carbon black, 2 to 4 wt% of alum and 3 to 6 wt% of wet strength.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a fruit cultivation bag according to the present invention.

As shown in Fig. 1, a bag for fruit cultivation is intended to protect fruits from pests, algae and natural environment. When a bag is put on a fruit, chlorophyll does not occur due to a shading effect, and the skin becomes thin and milky white. do.

 In the present invention, the bag for fruit cultivation 10 reflects radiant heat in addition to shading, and keeps the fruit in the bag at a proper temperature, thereby uniformly coloring the whole fruit.

In addition, the bag 10 prevents the liquid phase such as rainwater from entering from the outside when it rains, and prevents it from being torn or damaged even when it is wetted with water.

2 is a cross-sectional view of a fruit cultivation bag according to the present invention.

2, the bag 10 for protecting the fruit from external pests and natural environments has a white paper 11 on the surface and a black paper 12 on the back of the paper 11, The green sheet 11 and the black sheet 12 are formed in a weight ratio of 3: 2.

The bag 10 forms a water repellent coating on the surface of the paper 11 and the black paper 12 when they are joined together.

Here, the degree of beating is a measure of the ease with which the pulp fibers are dewatered, and the degree of beating is determined by the degree of freeness test, which measures how quickly a wetland layer is formed on a wire net from a certain amount of pulp liquid spilled on the wire net.

When the degree of beating of the bag 10 is 60 (SSR) or less, the density of the cut pulp is not dense, so that the durability is high, the transparency is high, and the wettability is high.

If the degree of beating of the bag 10 is 70 (SSR) or more, the density of the pulverized pump is dense and the puddiness is low, but the transparency is low and the water drainage is low.

Therefore, the bag 10 is preferably a high-degree-of-light shielding 65 (SSR: Schopper-Riegler) having good moisture permeability, translucency and durability.

The white paper 11 is manufactured by proceeding in the order of pulp washing, bleaching, beating, blending, papermaking, pressing, and drying so as to have a degree of beating of 25 (˚SR) as bleached chemical pulp.

The white paper 11 has wettability due to its moisture permeability, translucency and air permeability, so that the pesticide is absorbed when the pesticide is sprayed. Therefore, the pesticide prevents the pest and insects from approaching and penetrating to protect the fruit from pests and diseases.

The black paper 12 is manufactured so as to have a high resolution of 65 (SSR: Schopper-Riegler) by proceeding in the order of washing, bleaching, beating, blending, papermaking, Is composed of 80 to 90% by weight of pulp, 5 to 10% by weight of carbon black, 2 to 4% by weight of alum and 3 to 6% by weight of wet strength (wet strength).

When the pulp is mixed with the pulp at 5 wt% or less of the carbon black, the transparency is high due to low saturation of black color and the light shielding is low to increase the temperature, while the water repellent coating is good and moisture penetration is prevented, On the other hand, when the carbon black is mixed with 10 wt% or more of carbon black in the pulp, the saturation of the black color is high and the transparency is low and the shading is high, so that the internal temperature is lowered. On the other hand, Tearing or mold.

Here, the water-repellent coating is a process for preventing the penetration of moisture into the pulp, and the water-repellent process is performed to permeate water vapor and air. In the water-repellent process, the water- repellent agent is fixed in a thinly- So that air such as air or water vapor can freely pass through the cutting pulp space.

Therefore, in the cover 10, light transmission is reduced by the white paper 11 and the brightness of the inside is reduced by the black paper 12, so that the hue of the fruit skin is formed rapidly and the harvest time can be shortened. Water vapor permeates and permeates smoothly, and the light quantity, temperature and humidity of the fruit are appropriately maintained and controlled, thereby promoting fruit growth.

3 is a measurement chart of a bag for fruit cultivation according to the present invention.
