JPH07727U - Sheet material for packaging - Google Patents

Abstract

(57) [Summary] [Purpose] When carrying a relatively long object that requires surface protection and is not particularly rigid, unless it is stored in a case made of cardboard or wood, surface protection is of course important. Another object is to obtain an effective packaging sheet material when there is a risk of causing deformation of the article to be packaged. [Structure] The packaging sheet 1 of the present invention comprises a wax coating layer 2 obtained by coating a known paraffin wax in a molten state with a roll coater, a paper base material 3 of kraft paper, and each itself is adhesive. It comprises a pressure-sensitive adhesive layer 4 coated with a well-known latex material which has an adhesive property but does not have an adhesive property with respect to objects other than itself.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a packaging sheet material for packaging and protecting articles. More specifically, the present invention relates to a packaging sheet material for preventing scratches or the like from being generated on a surface of an article contained in a cardboard case or the like due to vibration during transportation.

[0002]

[Prior art]

 Conventionally, when transporting a product whose surface is coated or a material that is easily damaged by material, in order to protect the product, it was packaged with a resin foam such as polyethylene foam and then with a string or tape. Moreover, as such a thing involves complicated operations, a packaging sheet material using a foam has been proposed (Japanese Patent Publication No. 1-141515).

[0003]

[Problems to be solved by the device]

 However, resin foam such as polyethylene foam easily adsorbs dust on the surface due to static electricity, and it was difficult to prevent the inside surface of the foam with dust from damaging the object to be packaged. Furthermore, disposal of waste has become a problem after unpacking items packed with strings or tape. In addition, the above-mentioned packaging sheet material using the foam is particularly effective when it is not necessary to use other packaging materials such as cardboard, but when it is used not by itself but in a cardboard case or the like, it is costly. It will be costly. For example, when carrying a relatively long object that does not have high rigidity, such as a resin bumper, which requires surface protection, unless it is stored in a case made of cardboard or wood, surface protection is of course necessary. However, there is a possibility that the packaged object itself may be deformed. At this time, it was unavoidable that a packaging sheet using the above foam for the purpose of only protecting the surface would be slightly over-packaged.

In order to solve the above problems, the present invention provides a packaging sheet that is extremely useful for protecting the surface of articles that are carried by being stored in a case made of cardboard or wood.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, one side of a paper base material such as kraft paper or liner board paper is coated with wax or silicone resin, and the other side itself has adhesiveness, but is itself. Other than the above, a packaging sheet material was obtained which was provided with an adhesive layer having no adhesiveness.

[0006]

[Action]

 When an object to be packaged wrapped with the packaging sheet of the present invention (hereinafter simply referred to as a sheet) is housed in a case such as a cardboard box, the inner surface of the case and the surface of the sheet may be shaken or shaken during transportation. Even if they are rubbed against each other, the surface of the sheet coated with wax or silicone has improved abrasion resistance due to the lubricity of the coating agent and is not worn out. Further, since the inner surface of the sheet provided with the adhesive layer, which is in contact with the surface of the packaged object, does not rub against the packaged object, the surface of the packaged object is not scratched or the like. Furthermore, since the adhesive layer does not have adhesiveness to anything other than itself, it is possible to unwrap the packaged object without damaging it.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a sectional view showing a packaging sheet of the present invention, and FIG. 2 is a sectional view showing a state in which articles are packaged using the packaging sheet of the present invention and packaged for transportation. As shown in FIG. 1, the packaging sheet 1 of the present invention has a wax coating layer 2, a base material 3 of a Kraft paper, which has adhesiveness to each other but has adhesiveness to other objects. No adhesive layer 4. The wax coating layer 2 was obtained by coating a known paraffin wax in a molten state on the surface of the substrate 3 with a roll coater. The adhesive layer 4 is formed by coating a known latex material and has a property of self-adhesiveness with the same quality material but no adhesion with other quality materials. Although this latex material does not adhere to anything other than itself, it has a very high frictional resistance and is slightly rubbery to the touch. Therefore, slippage does not occur between the packaged object and the coated surface of the packaged object, and the surface is not scratched.

In the state in which the article shown in FIG. 2 is wrapped and packed for transportation, the article to be packaged 5 is wrapped in contact with the adhesive layer 4 of the packaging sheet 1 of the present invention and adhered at the joining portion 7. The layers 4 are attached and packaged by utilizing the adhesiveness of each other. The article to be wrapped 5 wrapped with the wrapping sheet 1 is housed in a cardboard case 6 so that it can withstand a slight load from the outside.

[0009]

[Effect of device]

 By using the packaging sheet of the present invention for packaging an article to be stored in a transport case such as a corrugated cardboard case, scratches or the like occur on the surface of the article to be packaged, although it can be obtained at a relatively low price. It is effective enough to prevent this.
