Description

Shopping Bag Fabric and Embossed Shopping Bag {SHEET OF SHOPPING BAG AND THE EMBOSSED SHOPPING BAG}

This invention relates to a fabric of a shopping bag and an embossed shopping bag.

Shopping bags are used to pack and carry purchased goods when shopping. In addition, shopping bags are often used to carry belongings with you when you go out. If you put the goods sold at the store in a shopping bag and give it to the buyer, the product's quality is outstanding and it is convenient for the buyer to carry the shopping product. In addition, the shopping bag is a disposable shopping bag provided by a product provider, an advertising shopping bag used as an advertising medium, a shopping bag shopping bag carried by a product buyer, and a fancy shopping bag.

As the material of the existing shopping bag, tough and thick papers, a sheet of paper and film laminated body, a nonwoven fabric, a polyethylene film, a laminate of nonwoven fabric and film is used. Plastic films used in shopping bags are both glossy and matte films.

In order to meet the high standard of living and social culture, to enhance the quality of market products, and to use it as a high-end advertising medium, shopping bag materials and beautiful shopping bags are needed. Shopping bags are a one-time consumer product, so even if their appearance is high quality, they cannot be used at high prices. Therefore, the shopping bag material needs a beautiful appearance and low price. The present invention aims to provide a shopping bag that is embossed to enhance the texture. In more detail, the present invention seeks to provide a shopping bag fabric that exhibits a good feel as in the leather feel by embossing the leather. The present invention aims to provide an inexpensive shopping bag fabric by employing an embossing process as a process of enhancing the texture. In this invention, the advanced texture to give the feel of leather is another expression of the shopping bag material sheet processed to have a sense of volume by embossing the surface.

In order to make the appearance of the shopping bag high quality (more beautiful), in more detail, it is manufactured by embossing the sheet of material fabric for manufacturing the shopping bag to express the high quality feel of leather. The embossing pattern generally embossed the material, thus exhibiting volume on the surface of the sheet of material similar to the feel obtained on leather.

The embossing treatment gives the bulk of the material a volume. In the embossing process, two or more films are embossed by overlapping or embossing the film and non-woven by overlapping two or more sheets. The thin film is laminated to increase the thickness to make it thicker and to increase the strength of the material. As such, the embossing process is a process of modifying the texture and at the same time it is a process of adjusting the strength and thickness of the material. In this invention, the plastic film includes a foamed thermoplastic plastic film and a foam sheet.

The embossing device is an embossing roll set consisting of an embossing pattern roll and a base roll engraved with the embossing pattern. The embossed pattern is a dot pattern or a line pattern having a constant area. A linear pattern is a pattern in which straight lines or curves are arranged. Dotted patterns are dotted patterns, diamond patterns, heart patterns, and other small patterns. These dots, lines and embossed patterns can be changed and selected as needed.

In the pattern roll, when the ultrasonic energy is embossing energy, the roll which is in contact with the ultrasonic horn and pressurized becomes the pattern roll. In a heat embossing roll, a heating roll is a pattern roll.

Nonwovens are thicker materials for their weight. Embossing the nonwoven fabric 20 and the plastic film 10 to increase the thickness and at the same time to produce a composite bonded to the two materials. Looking at the embossed surface of the composite 30 in which the two materials are laminated, the nonwoven thickness 20a at the embossed pattern pattern portion is squeezed and adhered between the pattern roll and the ultrasonic horn or the pattern roll and the base roll to become thin and dense. Becomes higher. The area before the pattern adhesion is preserved in thickness before embossing. The embossed pattern is thus denser and thinner than the pattern adhesive portion 100 and the thickness of the embossed pattern 200 is formed because it is superimposed without being bonded to each other while preserving the given thickness. By combining the pattern adhesive part 100 and the raised part 200, the surface of the laminate 30 exhibits a curved volume.

Conventional shopping bag fabrics are using a lot of milky white polyethylene film weighing 110g / ㎡ (about 110㎛ thickness).

In this invention to provide a shopping bag fabric, the present invention can use a non-woven fabric of weight 10-60g / ㎡ to show the characteristics of the shopping bag on the laminated sheet. Preferably, a PP nonwoven fabric having a weight of 25 g / m 2 (about 200 μm in thickness) is used.

If only one sheet of film or non-woven fabric is embossed, there is no excitement and no volume can be added to the material even if it is embossed.

Embossing two or more pieces of plastic films creates volumetric pattern adhesive and raised shapes.

When the plastic film is laminated on the back side of the nonwoven fabric and the pattern roll is brought into contact with the film, the pattern adhesive and raised portions are formed on the film surface.

When the plastic film is laminated on both sides of the nonwoven fabric and the pattern roll is brought into contact with one side film, the pattern adhesive part and the raised part are made on the film surface.

In this invention to provide a shopping bag fabric, the plastic film as a volume material overlapping one or both surfaces of the nonwoven fabric can use a film having a weight of 10-80 g / m 2. Preferably a PP film having a weight of 19 g / m 2 (thickness about 20 μm) is preferred.

When the plastic film is placed on both sides with the nonwoven fabric interposed, the three-layer laminated body (PP film 19g / m2, nonwoven 25g / m2, PP film 19g / m2) is manufactured. Becomes

The price of this three-layer laminated body, compared to the milky white polyethylene film weighing 110 g / m 2 (about 110 μm in thickness), which is widely used, results in a similar fabric price.

As oil prices and plastic raw material prices are expected to continue to rise, the weight of plastic films used as shopping bags should also be reduced to reduce the use of petrochemical products.

A preferred shopping bag fabric of this invention is as follows.

1. Nonwoven

The nonwoven fabric 20 uses a nonwoven fabric (mainly low density nonwoven fabric) having a low cost and a large thickness to weight. Such nonwovens include PP (polypropylene) spunbond nonwovens.

3. Embossing method

Ultrasonic embossing and heating roll embossing can be used. Ultrasonic embossing has a fine and clean outline of the embossed line. Ultrasonic embossing is desirable to obtain elaborate patterns.

The ultrasonic embossing pressurizes the material of the laminated body overlapped between the ultrasonic horn of the ultrasonic adhesive machine and the embossed pattern roll to form the pattern adhesive part 100 and the raised part 200 in the laminated body.

Heating roll embossing heat-presses the material of the laminated body laminated between the pattern roll and the base roll which were made of the heating roll, and forms the pattern adhesive part and the raised part in the laminated body.

The weight or thickness of the non-woven fabric and the plastic film, which is the material of the laminated body 30 of the shopping bag fabric, may be changed according to consumer demand. Embossing shapes can be freely selected from a wide variety of shapes. Heart shapes, leather images, stars, letter logos, etc. can be one of the embossed patterns.

4. Printing

Most shopping bags have a printed surface on the outside of the shopping bag to show the printed contents. The shopping bag material of the present invention is a pattern adhesive portion and a raised portion is arranged to exhibit a high quality, so that the printing placed on the shopping bag is printed on the plastic film for lamination which is the outer surface of the shopping bag before laminating with the nonwoven fabric. Printing of shopping bags may be printed on the surface of nonwovens.

As described above, the present invention provides a shopping bag that has a high-quality texture by embossed treatment, and provides a shopping bag fabric that shows a good feeling as in the feel of leather by embossing the leather, and upgrades the texture. Embossing treatment is used to provide low-cost shopping bag fabric.
