Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a functional packaging material provided with a paper texture,

The present invention relates to a functional packaging material provided to have a paper texture and a method for manufacturing the functional packaging material. More particularly, the present invention relates to a cosmetic bag pack for accommodating a bag or a mask pack for containing powdery or granular medicines (including quasi drugs) Is a technology related to packaging material that gives a sound source and a paper texture when the incision is cut and cut by laminating a nonwoven fabric on a thin packaging material provided in a food packaging pack provided to be packed after being sealed.

In general, a packaging material for forming a bag of medicines, cosmetics, or health foods is formed on a surface printing layer of paper, cellophane, polyester, nylon, polypropylene or the like with a storage substrate layer provided with an aluminum foil or gas barrier film layer, And is used to form a bag-packed product by heat-sealing the inlet portion after receiving the contents by forming the bag-shaped portion by heat sealing.

The packaging materials of the above-mentioned kind are not only free from the malodor of the contents contained therein, but also have properties (bending property) that do not damage the fragrance when the contents have a directional property due to the inclusion of volatile chemical ingredients, flaves or refreshing agents, (Non-adhesiveness of the direction), further low residual solubility, and the property that the contents of the solidified particles are physically adsorbed on the inner surface and do not remain after opening (non-sticking property of the powder) Even if the contents of the particulate matter are present in the sealing part in a small amount, good heat sealing (impurity sealing property) is required.

As a prior art for satisfying the above requirements and being provided as a packaging material for pharmaceuticals and cosmetics, Japanese Patent Application No. 2003717334 (filed on June 20, 2003) discloses a polyolefin layer and an anion- There is proposed a packaging material having an inner sealing layer in which an amorphous polyester resin layer containing an active agent or an amphoteric surfactant and an aqueous dispersion liquid type substantially free of an organic solvent having a boiling point of 100 DEG C or lower is formed in sequence.

The patented technique is a surface layer thermal sealing material applied on a lower layer polyolefin layer in which the use of an amorphous polyester resin of a solvent type conventionally used as a heat sealing material is avoided and an amorphous polyester resin of an aqueous dispersion type is used, An amorphous polyester resin of water dispersion liquid type wherein an organic solvent having a boiling point of 100 캜 or lower which is the boiling point is substantially removed and an anionic surfactant or an amphoteric surfactant is added is used instead.

In addition to the above techniques, wrapping paper of cosmetics or food products is made of paper or polymer film, which is mainly used. In order to reinforce the strength of paper, it may be used in multiple layers, or a polymer film may be laminated only on a part thereof Such paper packaging materials exhibit excellent moisture permeability and air permeability, but have a problem of low strength and good tearability, and exhibit problems of post-management that the packaging material is separated after being provided as a product.

In addition, the polymer film has excellent strength, but it has a problem that it is slippery in the case of a product in which the liquid is put on the hand, and there is no human-friendly feeling on the synthetic resin film, which is not preferred by people.

Compared to general merchandise or other contents, special consideration is required for packaging materials for medicines, cosmetics or health foods related to the human body. In addition to proving harmless to the human body before use, Careful consideration should be given to adverse effects on the environment as well as negative impacts on the environment.

In addition, the above-mentioned packaging material is required to keep the contents while maintaining sufficient mechanical strength. When the user opens the wrapping paper to use the contents, the user feels proper friction and softly and softly. - Paper texture Has been demanded, but there is not yet satisfactory.

The present invention relates to a packaging material using an environmentally friendly raw material, which can safely receive contents and maintain / maintain a certain mechanical strength sufficiently, but when the user wants to open the packaging material, it has a proper sediment force and a paper texture The present invention has an object to provide an environmentally friendly packaging material having the above properties.

In order to solve the above problems, the present invention provides a packaging material for a food, medicine, and cosmetic material, which has a paper texture between the print layer and the storage layer, wherein the micro nonwoven fabric is in the range of 0.09 mm to 0.15 mm And is characterized by the packaging material provided.

The printing layer of the packaging material may be selected from among OPP (Oriented Polypropylene), PET (polyester), and nylon. The material may be purchased from Hyosung, Colong, SKC, And the storage layer of the packaging material can be used in a structure in which LLDPE (Linear Low-Density Polyethylene) is laminated on aluminum. When the content of the packaging material receives sunlight or the like, it is used as a means for preventing the contents from being deteriorated The aluminum foil may be applied such that a linear low-density polyethylene (LLDPE) is laminated to a thickness of 1 to 5 탆 in a thin film product of 5 to 10 탆.

This paper describes a printing medium selected from OPP (Oriented Polypropylene), PET (polyethylene terephthalate) and nylon, and LLDPE (Linear low-density polyethylene) as a manufacturing method of environmentally friendly packing materials by wrapping paper of foods, medicines and cosmetics. And is configured to be laminated via a tie die dry bonding process or an adhesive bonding process when ultra fine nonwoven fabrics ranging from 0.09 mm to 0.15 mm are laminated between stacked storage layers.

The tie die dry bonding process may be applied such that the LDPE is molten and the bonding process is performed in the range of 5 to 30 μm, more preferably 12 to 17 μm, and the adhesive bonding process is performed by, for example, Unithane D 2-part type polyurethane-based quick-drying adhesive available under the trade designation " -650A " can be used.

Other embodiments in which the technical idea of the present invention is specifically embodied will be described in detail in conjunction with the drawings in the description of the specific contents for carrying out the following invention.

According to the present invention, since the packaging material is provided in a state in which the nonwoven fabric is inserted between the packaging materials, the surface printing layer is provided with a frictional force, and the storage layer provides an effect that the contents can be safely stored for a long time.

Also, the packaging material provided with the laminated structure of the present invention has excellent mechanical strength, has waterproof and moisture-proof property, has a proper sediment force when the user wants to open the packaging material, and provides paper texture enough to hear a paper- So that it is a luxurious packaging material and provides an excellent texture and a beautiful design packaging material as a human-friendly packaging material.
