The present invention relates to a shopping bag, and more specifically, to add a coating layer to the outer surface of an automatic paper shopping bag which is automatically processed after printing gravure printing on a rolled paper that is supplied in large quantities to enable mass production at a low cost. The present invention relates to a coated automatic paper shopping bag with excellent recyclability, which can prevent rising, water resistance, wrinkle prevention, printing surface protection, and ink leakage.

In general, shopping bags are manufactured to be convenient for transporting goods, and are used in department stores, large marts, and traditional markets, and are often made of paper material for low cost production.

The manufacturing method of such paper shopping bag is largely offset printing on sheet paper, lamination process of attaching film on printed paper, and then paper shopping bag manufacturing method and gravure printing on roll paper, then paper shopping bag It is divided into ways to make it.

However, the paper shopping bag manufactured by the former method has the advantages of preventing wrinkles and creases, tearing, and printing of printed ink and improving water resistance, which are mainly generated in the paper shopping bag, but are offset in sheet paper. Furthermore, the disadvantage of mass production and high manufacturing cost is raised due to the manual work of printing and attaching a film using adhesive on the printed paper.

In addition, the paper shopping bag produced by the latter method is an automatic manufacturing method that omits the lamination process of the former after printing gravure on a roll paper, and can be mass-produced, and it has the advantage of lowering the manufacturing cost, but wrinkles easily occur in the paper shopping bag. However, there are disadvantages in that printed ink cannot be protected due to the inability to protect the printed surface, and the resistance to water is greatly reduced and the strength is weak so that it is not easily recycled.

The present invention is devised to solve such a problem, the main purpose of the present invention is to form a coating layer on the outer surface of the automatic paper shopping bag, wrinkles easily generated in the paper shopping bag which is an advantage of the conventional handmade paper shopping bag Coated paper to meet the effects of mass production and reduction of production cost, as well as increase the degree of recycling by preventing water, preventing ink from being buried, strengthening resistance to water and improving durability. The purpose is to provide shopping bags.

The present invention to achieve the above object

In the paper shopping bag consisting of the body (1) and the handle portion (2),

It provides a coated automatic paper shopping bag, characterized in that it further comprises a coating layer 30 on the outer surface of the body (1).

Here, the cross section of the body (1) of the coated automatic paper shopping bag is characterized in that consisting of a coating layer 30 laminated on the paper layer 10 and the paper layer (10).

In addition, the cross section of the body 1 of the automatic paper shopping bag is characterized in that it further comprises a printing layer 20 between the paper layer 10 and the coating layer 30.

In addition, the coating layer 30 is made by spraying a liquefied PE-based resin, characterized in that the coating thickness is 20㎛.

Hereinafter, the present invention will be described in detail.

The term "automatic paper shopping bag" used in the present invention refers to a paper shopping bag made in large quantities through an automatic home factory after gravure printing on roll paper.

"Offset shopping bag" refers to a shopping bag that has undergone lamination process of attaching a film after offset printing on sheet paper.

The conventional automatic paper shopping bag is manufactured by purchasing a roll paper, printing gravure on the roll paper, and then processing it.

Here, the processing (waste) process is a step of inserting the printed paper into the automatic shopping bag maker, handle (handle) processing step, sheet, width (front and side) processing step, cutting processing step, bottom molding step, quality control ( QC) and packaging steps. The handle processing step may be performed manually after the bottom surface forming step according to the type and use of the shopping bag and the handle material, of course.

The present invention is characterized in that the automatic paper shopping bag further comprises a coating processing step of such a conventional shopping bag automatic process.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention in connection with the manufacturing process of the automatic paper shopping bag as follows.

1 is a perspective view for explaining an embodiment according to the present invention, Figure 2 is a cross-sectional view of the cut portion A-A of FIG. As shown in Figures 1 and 2, the shopping bag is coupled to the body (1) and the handle portion (2), the body (1) from the inside of the paper layer 10, the print layer 20 and the coating layer 30 It is composed of

The paper layer 10 uses a paper material used in manufacturing a general shopping bag. The base paper for forming the paper layer 10 is provided in a roll form in an automatic paper shopping bag manufacturing machine (not shown).

The print layer 20 is a layer formed on the paper layer 10, and prints a desired pattern, picture, text, etc. on a sheet of paper through a gravure printing method.
