The present invention relates to a method for manufacturing PE (polyethylene) for packaging having different inner and outer skin materials, and more specifically, the outer skin of the packaging paper is formed of polypropylene (PP), and the inner skin is LDPE (Low Density Polyethylene) and LLDPE (Linear). It is made of Low Density Polyethylene and forms eco-friendly packaging PE (Polyethylene) that does not induce environmental hormones, so it does not affect the human body and can be formed without any additional process. It relates to a manufacturing method of.

In general, PVC (Polyvinylchloride) is mainly used for packaging of foods such as sausage, confectionery, syringe, Ringer's solution, various medical supplies, bags, and quilts. Various toxic environmental hormone substances that affect the organs of the human body such as the effects of the system, endometriosis, developmental dysfunction and dysfunction were generated.

For this reason, there is a method of forming an endothelial material, which is directly in contact with a packaged product such as a food or medical article, a bag, a household goods such as a blanket, and the like, unlike the outer skin.

The outer shell is made of general vinyl or PVC (Polyvinylchloride), and the inner shell is formed of PP (Poly Propylene), PE (Polyethylene) or OPP (Oriented Poly Propylene) to replace PVC (Polyvinylchloride) for packaging.

The conventional packaging paper as described above is formed of a material made of PP (Poly Propylene), PE (Polyethylene) or OPP (Oriented Poly Propylene) to form a different material of the outer skin and the inner skin to directly contact food, medical supplies, household goods As it does not affect the human body, it can be called an eco-friendly wrapping paper.

However, conventional packaging paper is manufactured separately from general vinyl or PVC used as the outer skin and PP (Poly Propylene), PE (Polyethylene), OPP (Oriented Poly Propylene) used as the inner skin, and then laminated the outer skin and the inner skin Since the production process is cumbersome, the production cost is increased, which lowers the product's price competitiveness, and heat or glue is used in the lamination process of the inner skin and the outer skin. Followed by possible closures.

In addition, in case of OPP (Oriented Poly Propylene) used as the inner skin, if it is torn well and there is an attachment such as sewing or a separate button necessary for packaging, the packaged item comes in contact with the outer shell 11 again because it is easily torn. There is a problem such as exposure to the material.

Therefore, the present invention has been made in order to solve the above-mentioned end, and the outer skin mixture and the endothelial mixture is separately mixed and mixed, each mixture is attached to the endothelial and the outer skin while being transported without any additional process, the operation is simple By lowering the manufacturing cost to increase product competitiveness, of course, it is an object of the present invention to provide a method for manufacturing PE (polyethylene) for packaging, which is different from the environment-friendly inner skin material that does not affect environmental hormones.

In order to achieve the above object, the present invention provides a method for manufacturing a packaging paper having different inner and outer skin materials:
Outer sheath (101) containing soft PP (Poly Propylene: Korea Emulsifier-PP1088A / B) and viscous PP (Poly Propylene: LG Chemical Manufacturing-R3410) in a ratio of 1: 6 (25 kg bag) ) Mixture (101a) at high temperature in the shell mixture
Mixture (102a) for endothelial (102) in which LDPE (Low Density Polyethylene: LG Chem, BF511) and LLDPE (Linear Low Density Polyethylene: Samsung Chem, LD 503G) are mixed in a 6: 1 ratio (25 kg bag). Is mixed at high temperature in the endothelial mixture,
Each of the mixed high-temperature mixtures 101a and 102a is simultaneously discharged and transported from the mixing material container, and the mixture 101a for the outer skin 101 and the mixture 102a for the inner skin 102 are adhered to each other in close contact with each other. Make sure,
The tightly coupled packaging PE 100 is transferred to a water tank, characterized in that the manufacturing method of the packaging PE 100 is different from the material of the endothelial and the outer shell formed by cooling in water at 15 ℃.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a packaging PE with different inner and outer materials according to the present invention, Figure 2 is a cross-sectional view showing a packaging PE with different inner and outer materials according to the present invention.

 The present invention relates to a method for producing packaging paper PE (polyethylene) having different inner and outer skin materials.

The mixture for the shell 101 forms a mixture 101a for the shell 101 at a ratio of 1: 6 based on 25 kg of soft PP and polypropylene having a viscosity.

PP (Poly Propylene) mixed in the above slightly different properties for each production company, using a soft PP1088A / B produced by Korea Emulsification, the viscosity of PP produced by LG Chemical used R3410.
In this way, PP (Poly Propylene) mixed with different properties is produced by controlling the strength, elasticity, and elasticity of the outer skin. Therefore, it prevents damage such as tearing or sagging during use, and adjusts it to a thickness appropriate for the purpose. To make it easy to produce.

Meanwhile, the mixture 102a to be used as the endothelium 102 is a low-density polyethylene (LDPE) product produced by LG Chem, which uses BF 511, and has a highly elastic LLDPE (Linear Low) produced by Samsung Chem. Density Polyethylene) LD 503G is mixed.
The mixing ratio of LDPE and LLDPE is mixed at high temperature in a ratio of 6: 1 based on a 25 kg bag.

Production machine name used in the present invention produced the packaging PE (polyethylene) using SM- Ø60M * 60M PP 2LAYER

First, two raw material mixing vessels for mixing the raw materials are formed, and the raw material for the endothelial material and the outer shell material are added to each of the raw material mixing cylinders and mixed at a high temperature.

Each of the mixed raw materials is simultaneously discharged from the endothelial mixing cylinder and the outer skin mixing cylinder, and at this time, the discharged two raw materials are attached to each other while passing through the rollers.

Therefore, no additional attachment process is necessary. The mixtures 101a and 102a attached to each other while being stretched are transferred while passing through a water bath maintained at 15 ° C.

The bath allows the mixture (101a) (102a) to be cooled while passing through the water, the water is always maintained at 15 ℃, the mixture cooled at 15 ℃ has the properties of softer packaging PE (polyethylene).

On the other hand, it is also possible to prevent the static electricity by adding an antistatic agent when mixing the materials.

Therefore, the manufacturing method of the packaging PE with different materials of the inner and outer skins of the present invention is useful for the packaging of food products such as sausages, confectionery or medical products such as syringes and medicines by avoiding contact with environmental hormones that are toxic to humans. Packaging PE (polyethylene) has a soft property, so even if sewing to form a quilt bag does not tear or break.

In addition, a bag may be formed by forming a thick material of packaging PE (polyethylene).

According to the above configuration and action, the present invention, by forming a packaging PE (polyethylene) to change the material of the endothelial and the outer shell by a simple operation without additional processing to lower the manufacturing cost, increase the competitiveness of the product, as well as environmental hormone It is possible to form packaging PE (polyethylene) with different environmentally friendly materials.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments and that various modifications and variations can be made without departing from the spirit and scope of the present invention, and therefore such modifications or Modifications should be within the scope of the claims of the present invention.
