BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a plastic wrapping paper,

The present invention relates to a method for manufacturing a synthetic resin wrapper and a synthetic resin wrapper manufactured using the same. More specifically, the present invention can continuously produce a synthetic resin wrapper formed in an envelope shape by continuously fusing and cutting a supplied synthetic resin material, The information such as the name and the contact information can be printed on the both ends of the shaped synthetic resin wrapping paper and the printed information can be easily replaced and the synthetic resin wrapping paper that has been manufactured can be transferred to a specific region, The present invention relates to a method for manufacturing a synthetic resin wrapper and a synthetic resin wrapper manufactured using the same.

The use of discarded low density polyethylene, high density polyethylene, and linear low density polyethylene to provide recycled bags in general is disclosed in Korean Patent Laid-Open No. 101812, " Method for regenerating waste vinyl and waste plastic bags for agricultural use ".

It is an object of the present invention to provide a method for separating low density polyethylene, high density polyethylene and linear low density polyethylene from a vinyl containing impurities and foreign substances in order to regenerate vinyls which are discarded under poor conditions. And it can be applied to recycled bags by using the materials.

However, a known example is disclosed only for the method of regenerating waste vinyl, and a method and apparatus for manufacturing a specific recycle bag are not disclosed, and it is inconvenient for a person who manufactures the bag to improve it I followed.

In order to solve the above problems, a method of manufacturing a recycle bag has been developed. In the method of manufacturing a bag according to the related art, 70% by weight to 90% by weight of low density polyethylene as a regenerator and 10% 1 to 10 parts by weight of a linear low density polyethylene as a raw resin and 0.1 to 5 parts by weight of a pigment are mixed with 100 parts by weight of a film resin and the film resin is extruded by 10 to 30% And then the film resin is melted and transferred in a gel state to form a cylindrical film continuously through an extrusion passage formed in a blow die of a blow extrusion die to which air is supplied.

BACKGROUND ART [0002] The background art of the present invention is disclosed in Korean Patent Registration No. 10-0781691 (published on Dec. 03, 2007, entitled " Method for manufacturing recycled bag and manufacturing apparatus thereof).

The conventional envelope manufacturing method does not require a separate printing process for printing information on the outer wall of the envelope. Therefore, it is necessary to provide a separate packaging sheet for promoting the information such as the name, .

Further, in the conventional method for manufacturing an envelope, since the operator prepares and stacks the produced plastic bags one by one, it is difficult to reduce the time and cost required for transportation and packaging after the bag is manufactured.

Therefore, there is a need for improvement.

The present invention can continuously produce a synthetic resin wrapping paper which is formed in the form of an envelope by continuously fusing and cutting the supplied synthetic resin material and can print information such as a company name and a contact name on both sides of the envelope- The present invention provides a method for manufacturing a synthetic resin wrapping paper having a molding character at both end joining portions and a synthetic resin wrapping paper manufactured using the synthetic resin wrapping paper because the manufactured synthetic resin wrapping paper is manufactured while transferring the manufactured synthetic resin wrapping paper to a specific region. .

The present invention relates to a synthetic resin wrapper formed in the form of an envelope, wherein both ends of the wrapper are open at both ends except for the one end, and a pair of synthetic resin sheets are adhered to each other; And molding characters formed in the both end joining parts, wherein information of a company including a business name and a contact is formed while the both ends are deformed by a heating and pressing process.

In addition, a closed end portion forming the bottom surface of an envelope-shaped wrapping paper is formed between one pair of end portions of the pair of end portions of the present invention.

Further, an open end portion constituting the upper end of an envelope-shaped wrapping paper sheet is formed between the other end portions of the pair of end portions of the present invention, and the open end portion is formed by cutting a part of the other end of the wrapping paper.

The method for manufacturing a synthetic resin wrapping paper according to the present invention and the synthetic resin wrapping paper produced by using the method are characterized in that both ends of a pair of wrapping paper are overlapped with each other to form wrapping paper in an envelope shape, Since the molding part for printing the company name or the contact information is provided, the wrapping paper can be formed into an envelope shape and at the same time, various information can be printed at the same time, thereby saving the time and cost required for manufacturing the wrapping paper.

In addition, since the molding roller having the molding part is formed of a plurality of blocks, the molding part can be easily replaced, so that a variety of characters and information can be selected, and both ends of the wrapping paper There is an advantage that it can be printed on the coupling part.

In addition, since the method for manufacturing the plastic wrapping paper according to the present invention and the plastic wrapping paper manufactured using the method are provided with the transfer part for transferring the wrapped paper one by one to the specific place, It is possible to save time and cost in bundling and packaging.
