Food packaging is the storage and storage of food, and freshness and preservability are very important. In order to maintain the freshness and preservability of the food, the barrier property of oxygen and moisture must be excellent. The conventional wrapping paper is a multi-layered film made of a different material including a metal such as aluminum, as shown in Korean Registered Utility Model No. 20-0251193 and Domestic Registered Utility Model No. 20-0222620, thereby improving the barrier property of oxygen and moisture. In order to improve the freshness and preservability of foods, much efforts have been made to impart antioxidant functions in addition to blocking properties.
However, packing materials having an antioxidant function for suppressing oxidation of foods are difficult to select and obtain proper antioxidants, and the cost is high. Korean Patent Laid-Open No. 2000-0024191 has developed a low-density polyethylene film containing fine powder of jade, but objective quality characteristics and leading elongation effect have not been clarified. In addition, the conventional paper packaging material has been coated with a coating solution containing loess powder, but it did not show the antioxidative effect of fruits and foods. As such, packaging paper in which antioxidants are dispersed or coated is insufficient to enhance the freshness of the food. Accordingly, there is a demand for a packaging sheet for food which can effectively exhibit the antioxidative function together with the barrier properties.
A problem to be solved by the present invention is to provide a packaging sheet for foods using an antioxidant substance so as to be able to effectively exhibit antioxidative function together with blocking ability.
One of the packaging sheets for foods using antioxidants for solving the problems of the present invention is a packaging sheet for foods using antioxidants in which a substrate layer, an antioxidant blocking layer and an oxygen absorbing layer are sequentially laminated, Alcohol, and antioxidant, and the coral absorbent layer is a layer in which an oxygen absorbing material is mixed with an unleaded polypropylene.
In the wrapping paper of the present invention, the antioxidant may be at least one selected from the group consisting of psittaci, diatomaceous earth, polyphenol, flavonoid, carotenoid, catechin, vitamin C and tocopherol. The antioxidant may be a hydrogen producing material. Wherein the hydrogen-producing material comprises an alkali metal and an alloy of the alkali metal, an alloy of an alkaline earth metal and the alkaline earth metal, a stabilized alkali metal and an alloy of the stabilized alkali metal, a stabilized alkaline earth metal ) And the stabilized alkaline earth metal alloy. The hydrogen-producing material may be selected from the group consisting of boron-group metals and alloys of the boron-group metals, hydrides of metals or metal alloys, borohydrides of metals or metal alloys, aluminohydrides of metals or metal alloys ), And tourmaline minerals.
In the preferred wrapping paper of the present invention, both sides of the oxygen absorbing layer may be attached with a non-drawn PP layer. And a fine pore penetrating the oxygen absorbing layer to expose a part of the antioxidant blocking layer. The cross-sectional shape of the micro pores may be circular, polygonal or a combination thereof. The space formed by the micropores may be a truncated cone, a truncated pyramid, or a combination thereof.
Another object of the present invention is to provide a wrapper for foods using antioxidants in which a substrate layer, a barrier layer, an oxygen absorbing layer and an antioxidant layer are sequentially laminated, Wherein the oxygen absorbing layer is a layer in which an oxygen absorbing material is mixed with an unleaded polypropylene, and the antioxidant layer includes an antioxidant substance.
According to the packaging sheet for food using the antioxidant of the present invention, the antioxidant layer containing the antioxidant can be used to effectively exhibit the antioxidant function. In addition, antioxidants can significantly improve the degradation and browning of food, leading to deterioration and corruption caused by bacterial growth. Particularly, the antioxidant is preferably a hydrogen-producing material.

When stretched, the stretched polypropylene is arranged in a direction in which the molecular arrangement is stretched and the strength is increased in the stretched direction. Particularly, the biaxially stretched polypropylene has a similar strength in the transverse and longitudinal directions, a strong mechanical strength, good printability and processability. The stretched polypropylene is excellent in transparency, moisture resistance, and oil resistance. The core layer includes a modified polyolefin and a thermoplastic elastomer containing a random functional group in a random polypropylene. Here, the random polypropylene (PP) refers to a random copolymer or a terpolymer, and a random terpolymer is preferable. The random copolymer is a random arrangement of two monomers by copolymerizing propylene with ethylene. A random terpolymer is a kind of random copolymer made by polymerizing three monomers of ethylene, propylene and butene-1. The random polypropylene (PP) may be a polypropylene type resin having a melt index (g / 10 min) of 0.3 to 30 and a melting point of 145 占 폚 or higher, preferably 150 占 폚 or higher. As such a resin, a randomly copolymerized resin containing about 0 to 4% by weight of -olefin in propylene is used.
Since the modified polyolefin has a polar group, an acid-modified polyolefin having excellent adhesive sealing property may also be used. The acid-modified polyolefin is a polyolefin graft-modified with an acid such as maleic anhydride. For example, an acid-modified polyolefin can graft copolymerize a polyolefin resin with an unsaturated carboxylic acid such as acrylic acid or maleic anhydride, and the modified polyolefin resin having a carboxyl group uses an ethylene-based ionomer resin having a carboxyl group in the molecule. The ethylene-based ionomer resin is a resin that is pseudo-crosslinked with a metal ion such as a zinc ion, a potassium ion, a sodium ion, a magnesium ion, or a lithium ion between molecules of an ethylene copolymer such as an ethylene methacrylic acid copolymer or an ethylene acrylic acid copolymer Lt; / RTI > The modified polyolefin is added and added in an amount of 5 wt% to 50 wt% with respect to the entire core layer.
The thermoplastic elastomer is a molecular structure of a typical triblock copolymer, and other multi-type block copolymers, graft copolymers chemically crosslinked by mixing resin and rubber, and ion crosslinked copolymers. The thermoplastic elastomer exhibits a hard, dispersed two-phase structure in which three-dimensional mesh knots are formed on a homogeneous rubber. Depending on the type of hard phase, it is classified into a polystyrene type, a polyolefin type, a polyvinyl chloride type, a polyurethane type, a polyester type, and a polyamide type. In order to show rubber elasticity, it is divided into a freeze phase, a crystalline phase, a hydrogen bond with the crystal phase, and ion bridging depending on the respective hard chain properties. At this time, the polyolefin elastomer was used in consideration of the compatibility with the homopolypropylene which is the main component of the intermediate layer. The first and second non-tear-

The antioxidant may be present in various materials. For example, there are sugars, diatomaceous earth, polyphenols, flavonoids, carotenoids, catechins, vitamin C, tocopherols, iron oxides and the like. The above-mentioned schistite is a natural-nanostructured composite material containing 30 to 40% by weight of carbon and 70 to 60% by weight of silicate as a carbon-containing rock, and may contain aluminum, magnesium, potassium, sulfur, calcium, It is a substance containing other trace elements. In the case of Schunggit, the spun-grit carbon material is composed of globules 2 to 30 nanometers in size, forming nanostructures, and has natural fullerene and high-order fullerene particle structures. The catechin is green tea extract. The tocopherols include synthetic tocopherol (dL-tocopherol acetate), TBHQ (tertiary butyl hydroquinone) or natural tocopherol. The diatomaceous earth transforms the ambient moisture into moisture having high antioxidant activity, thereby substantially eliminating oxygen which is the cause of the shrinkage.
A hydrogen producing material is presented as a sulfating material according to an embodiment of the present invention. The hydrogen-producing material is a substance that spontaneously generates hydrogen upon contact with moisture. Hydrogen is a sulfated material that is fast to diffuse and has no harmful effects from use. The fast diffusion is because hydrogen is the smallest molecule. Hydrogen is a hundred times smaller in molecular size as compared to the above-mentioned sugi ghit, diatomaceous earth, polyphenol, flavonoid, carotenoid, vitamin C and tocopherol. In addition, hydrogen selectively neutralizes only oxygen, which is a factor such as rancidity. Some hydrogen-producing materials according to the present invention are highly reactive and can generate hydrogen even in contact with moisture in the atmosphere. The
Wherein the hydrogen-producing material comprises an alkali metal and an alloy of the alkali metal, an alloy of an alkaline earth metal and the alkaline earth metal, a stabilized alkali metal and an alloy of the stabilized alkali metal, a stabilized alkaline earth metal And the stabilized alkali metal or the stabilized alkaline earth metal may be one of a layer material such as graphite, a porous material such as silica gel or zeolite, a carbon material such as carbon, A reaction of any one of artificially formed nanostructures such as nanotubes, porous Si, porous SiC, porous Si 3 N 4 , aerogels, and xerogels with the alkali metal or the alkaline earth metal to control the hydrogen generation reaction And enhance stability.
Other hydrogen-producing materials include boron-group metals and alloys of the boron-group metals, hydrides of metals or metal alloys, borohydrides of metals or metal alloys, aluminohydrides of metals or metal alloys aluminohydride, and tourmaline mineral. The boron group metal may be boron (B), aluminum (Al), or gallium (Ga). The catalyst or the additive may promote the generation of hydrogen by at least one of a transition metal, a carbon material, and an organic acid.
