It is applied to agricultural products such as fruits, vegetables and flowers to protect fruits from pests, contributes to the improvement of quality of sugar, color and appearance of agricultural products, improves the workability of packing materials and facilitates quality control packaging for agricultural products. It is about.

In order to protect the fruit from pesticides and pests, paper materials and fruit packaging materials have been used a lot. However, for the material deformation of paper materials, labor costs will be borne by non-productivity such as secondary coating process, tertiary bonding and bonding process. As a result, the burden on farm households is increasing due to the high price of fruit packaging materials.

In addition, the packaging material made of conventional paper was easily torn when the bird pecked with its beak, so that the fruit could not be used to feed, and the upper part of the packaging had to be covered with an umbrella-shaped plastic film to protect the fruit from the damage of the bird. There was also a problem going. Furthermore, agricultural products other than the above-mentioned fruits, for example, vegetables such as tomatoes, minitomatoes, cabbages, cabbages, asparagus, other top mushrooms, mushrooms such as dance mushrooms, and potted plants such as roses and butterfly eggs may be produced in the growing process. Pests, such as very small pests called Thrips, have had the problem of damaging pollen, leaves, flowers, fruits or young branches.

As a substitute for improving the problems of the packaging material made of paper as described above, Japanese Unexamined Patent Publication No. 10-52180 discloses a fruit packaging material provided with a ventilation hole in a transparent or translucent plastic film, but the opening of the packaging material according to the present invention A water hole is provided at the bottom of the miner and the packing material. If the pore size of the vent hole exceeds a predetermined range, water may be permeated from the outside. Although it is judged that a channel is provided, there is still a possibility that pests such as ants, aphids, and slips remain from this channel.

In order to solve this problem, there have been attempts to use synthetic resin films (PE, PP, etc.) which have a good production process, but the film adheres to the pulp due to humidity emitted from the flesh itself because the film itself is non-breathable. Rather, it was a case of accelerating the occurrence of pests that favor over-humidity, or causing the corruption and failing to apply.

In order to overcome the problems and limitations of the packaging material made of paper as described above, the present invention is to provide a film having a permeable (concave-convex) shape on both sides of the synthetic resin film while having breathability and gas permeability. And it is intended to be used as a packaging material for fruit or vegetable cultivation or storage using a plastic film having a gas permeability and a protrusion (unevenness) shape on both sides thereof.

In addition, the purpose of the present application by using a punching method using the roller and develop a bi-directional pressure roller, which can provide a film having a projection (unevenness) phenomenon on both sides of the film while having the breathability and gas permeability. .

Therefore, the packaging body of the present application is configured to have a breathable or gas permeable size of the water does not pass, and to form a structure for replacing the air in the packaging material with outside air by passing air from the micro-pores, the most suitable environment for agricultural products The purpose of the present invention is to find a range of pore size, pore area ratio, or porosity of micropores that create conditions, and to provide agricultural product protection packaging materials that contribute to the improvement of fruit quality, sugar content, yield and workability.

The present invention is to use a plastic film to overcome the problems and limitations of conventional paper packaging materials in the process of growing agricultural products such as fruits, vegetables and flowers, the plastic film material is attached to the agricultural products or flesh to protect In order to eliminate the phenomenon of close contact, the plastic film fabric to be processed is passed through the upper and lower immersion rollers having fine perforation needles at regular intervals, and the perforated protrusions of the minute protrusions (unevenness) shape on both sides of the film at regular intervals. It is to provide an apparatus for manufacturing a packaging material, a manufacturing method using the apparatus, and the resulting packaging material, characterized by using a puncture roller to configure.

The method of manufacturing the packaging material of the present application is to pass the plastic film fabric to be processed through the upper and lower combination rollers having a fine perforation needle to the minute projections (concave-convex) of about 0.01 ~ 0.9 mm on both sides of the film about 2mm ~ 8mm Combined with the manufacturing method characterized in that configured to intervals of so as to add a film modification process, a process of adding a vaporizing insecticide, etc. before or after passing through the impregnation roller having a puncture needle.

Silver is a packaging material for protecting the agricultural product by covering the produce in the process of cultivating fruits, vegetables and flowers, the packaging material may be composed of a multi-packaging material made of a plastic film having an opening in at least one direction, The multi-packaging material includes at least a portion of the packing material and a packing material body including a plurality of air permeable, gas-permeable and non-permeable micropores on at least part of the packing material, and a mounting portion for attaching the packing material body to the support of the agricultural product. Agricultural product protection packaging material Will be provided.

In order to achieve the above object, the present invention passes the upper and lower combination rollers having a fine perforation needle to form a micropores (concave-convex) shape of about 0.01 to 0.9 mm at intervals of about 2 mm to 8 mm on both sides of the film. Since the film has a projection (concave-convex) shape on both sides of the film, the film itself is not only breathable, but also artificially creates a space between the pulp and the film so that the packaging material does not adhere to the contents and the convenience of processing the synthetic resin. Therefore, the color of the film is selected and given so that the amount of sunlight can be adjusted according to the characteristics of the fruit. Therefore, the colorability is improved, and the value of the product is enhanced. Also, the production of vaporizable film by prescription that can be disliked or eliminated according to the toxicity of various pests and algae Make

For example, the above-mentioned packaging material may be colored in multiple layers, or the selection of vaporizing chemicals may affect the effects on plants (fruits) related to the photosynthetic action of light and the widespread pests on the crops depending on the characteristics of the fruit or vegetable to be grown. Vaporizing agent can be selected and used as a target.

In other words, the use of special vaporizing additives (such as magpies, naphtharene, which is not like algae or some pests) is added to the outer or inner layer of the bag, thus providing a film containing vaporizing substances to prevent the damage of algae and general pests. It is possible to select and use vaporizing agents for the effects on related plants (fruits) and pests prevalent in the crops.

In addition, the agricultural product protective packaging material according to the present invention is composed of a double to a multi-packaging material may be made of a transparent to semi-transparent and / or a light transmissive film that the inner packaging material selectively transmits only the sunlight of a specific wavelength of the sun or through the sunlight. , The outer packaging material of the double packaging material may be composed of a light-shielding film to block or block some of the sunlight, for example, in the case of the apple protective packaging material fruit of the double packaging material at the initial stage of fruit growth By attaching it to the sun, and blocking the sun, and leaving the inner packaging material at the stage where the fruit grows to some extent, the outer packaging material is peeled off, and the sunlight transmitted through the transparent inner packaging material can be irradiated to the fruit and colored red.

It is also possible to add a transparent organic red pigment to the inner packaging material in order to make it easier to transmit the red wavelength light in order to increase the red pigment of the fruit, and also to put the double packaging material on the grower of the produce, after harvesting the produce, The outer packaging material may be removed, and the inner packaging material may be used as a packaging material for merchandise, and it is not limited to the double packaging material, but may be composed of three or more multi-packaging materials as necessary, depending on the type of fruit or vegetable and other agricultural products to be protected. Any application can be applied.
