Description

Packing material comprising UV protector having air bubble sheet structure}

The present invention relates to a sheet member for packaging, and more particularly, to an air sheet packaging material for protecting a packaged article from external impact and ultraviolet rays.

Packaging materials are not only to enhance the appearance of the packaged goods, but also to protect the packaged goods from external conditions. In particular, packaging of automotive parts such as electric and electronic products, bumpers, fenders and doors is usually made of styrofoam. In the box, electrical and electronic products and automotive parts are separated from the inner wall of the box wall so as to absorb and alleviate the impact force from the outside that may be applied to the packaged object.

On the other hand, the wrapped object is wrapped in a sheet member, and then put in a paper box, the sheet member was mostly made of a foam member manufactured in the form of a bag. Such foam members include foam rubber made by foaming natural rubber (latex), and foamed polyethylene having expanded porosity under the action of a foaming agent. The former is generally mixed with natural rubber latex, sulfur dispersion, vulcanization accelerator, and the like, and a small amount of sodium hexafluorosilicate, a coagulant, is mixed at high speed in a bubbler. It is made by foaming.

The sodium hexafluorosilicate is decomposed as shown in the following ①, and mainly gelled and solidified due to the tetragonal silicon oxide Si (OH) 4.

Na2SiF6 + 4NH3 + 4H2O → Si (OH) 4 + 2NaF + 4NH4F .......... ①

The solidified in this way is put in a mold and heated with hot water or steam to vulcanize and foam.

The foam rubber thus produced has a soft and elastic physical property with an apparent specific gravity of 0.085 to 0.17, and is widely used in mattress cushions or vehicle seats. In addition, it is not only used as a wall or ceiling material of prefabricated houses, but also widely used as a cushioning packaging material for cameras, electric appliances, electronic parts, and automobile parts.

However, the packaging material manufactured using the foam member as described above has a limit in securing a buffering effect, and thus is easily deformed or damaged by the weight of the packaged material, and there is a problem in that it is not environmentally friendly. Therefore, in order to protect the packaged goods under external conditions such as impact, it is required to maximize the effects of buffering / water resistance / absorption and to recycle and to develop an environment-friendly packaging material that is harmless to the human body.

In addition, gravure printing is possible on the outer surface of the nonwoven fabric layer 106 and / or the hydride polyethylene film layer 108.

The air capsule sheet layer 104 is composed of an upper film member 112, a lower film member 114 and an uneven sheet member 116, the upper and lower film members 112 and 114 are spaced apart from each other. It is provided to be arranged, the concave-convex sheet member 116 disposed between the upper film member 112 and the lower film member 114, a plurality of recesses are formed to form a plurality of air capsules filled with air, such Under the state, a surface portion of the upper and lower layer film members 112 and 114 except for the plurality of main parts thereof is heat-sealed to form a plurality of air capsules filled with air. The upper film member 112 of the air capsule sheet layer 104 may extend the shrink film end (C) at one side end of the long side portion thereof, and the shrink film end (C) may be formed on the surface and the backside tape of the other member. By means of attachment in an extended state. Meanwhile, the air capsule sheet layer 104 may be formed of a multilayer.

The nonwoven fabric layer 106 and / or the ethylene polyethylene film layer 108 may be attached through heat fusion at the surface in contact with the air capsule sheet layer 104. In addition, the edge portion may be heat-sealed to cut the air capsule sheet layer 104, the nonwoven fabric layer 106, and / or the hydride polyethylene film layer 108, which are attached and stacked, to take the form of a bag ( 3).

Commonly used raw materials worldwide are polyester, viscose rayon, nylon, polypropylene and the like, cotton, hemp, wool, asbestos, glass fiber, acetate and the like. There is no restriction on the type of nonwoven fabric layer used in the present invention, and any product that is not commercialized or not may be used.

The HEIDEN polyethylene film layer 108 is HDPE (high density polyethylene) made by ethylene polymerization using naphtha obtained by distilling crude oil as a raw material, and these HEIDEN polyethylenes are each produced by different catalysts and polymerization methods. That is, the polymerization of ethylene is classified into high pressure polymerization method, middle pressure polymerization method and low pressure polymerization method according to the degree of pressurization during polymerization. In particular, the pressure polymerization method is applied at a pressure of about 20 to 30 atmospheres and then uses a catalyst such as chromium to about 150 ° C. The method of polymerizing ethylene by heating is to produce hydride polyethylene by this method. Such high density polyethylene has good mechanical strength, weather resistance, extrudability, heat sealability, heat sealability, creep resistance, heat resistance, processability, drawing property, heat stability, etc., so that general industrial packaging materials, shopping bags, agricultural mulching films, general and industrial use It is widely used as a material for pipes, hot water ondol pipes, containers for shampoos, detergents and cosmetics, chemical and chemical containers, food containers, and general rope / fish net / tape. The ethylene polyethylene film layer 108 may be a hemp cloth or a non-woven fabric coated with a polyethylene film, of course.

In the sunscreen, the penetration of UV light by chemical absorption by using an organic material such as "UV light scattering agent" and PABA, which prevents UV penetration by physical scattering using inorganic materials such as titanium dioxide. There is an extinction "ultraviolet absorber". UV absorbers have high chemical stability, absorption of a wide range of ultraviolet light, high stability to heat and light, and properties that do not react with other components. Most UV absorbers are aromatic compounds with carbonyl groups, and electron donors such as amino groups and methoxy groups are located in the ortho or para position of the benzene ring. . The short wavelength absorbs high energy ultraviolet rays and is converted into low energy infrared rays which are not harmful to the human body and are emitted slowly. This is because these chemical structures have a resonance structure that is advantageous for absorption of ultraviolet rays. Paraamino benzoic acid (PABA), para-amino benzoic acid glyceryl (Glyceryl P-Aminobenzoate) and the like has excellent ultraviolet absorption effect, but there is a problem in safety. UV absorbers have the advantage of increasing the blocking range and effect when used in combination with different blocking effects for each area. PABA, its derivatives, salicylic acid derivatives, and cinnamic acid derivatives are sunscreens that have been used early on. Among these, octyl methoxycinnamate (OMC), which is a cinnamic acid derivative, and butylmethoxydibenzoyl methane (BMDM), a UV-A absorbent, are widely used. Benzophenones are also commonly used as UV-A absorbers. Ultraviolet scattering agents are opaque materials that reflect or disperse ultraviolet rays and visible light, and titanium dioxide (titanium dioxide), zinc oxide (ZnO), and the like are used. The UV scattering agent has no deterioration of the UV blocking effect over time, little legal restriction on the compounding limit, high safety, and a wide UV absorption wavelength band.
