1. Design production stage

The design production step is a step of producing a design formed on the outer surface of the food packaging pack according to the present invention. The production of such a design may be designed using a computer program.

2. Copper plate production stage

The copper plate production step is a step performed after the design production step, and is performed through a common copper plate manufacturing process.

In the copper plate manufacturing step, the cylinder is plated with nickel (Ni) and copper (Cu), the cylinder is polished to perform electronic engraving, and then plated with chromium (Cr) to be produced through a calibration test. Can. Since the copper plate manufacturing process is obvious to a person skilled in the art, detailed description will be omitted.

3. Printing process steps

The printing process step is a step of making a large amount of copies by depositing ink on the copper plate produced in the copper plate production step so that the design produced in the design production step can be transferred to the printing paper. At this time, a large amount of replica means that a plurality of designs are copied in a length direction on a printing paper having a predetermined length.

Such printing is classified into newspaper printing using a convex copper plate, offset printing using a flat copper plate, and griba printing using an opaque copper plate, but the present invention is not limited thereto.

However, preferably, gravure printing can be used, which expresses a color difference between light and dark and rich, so that a rich expression of the design is possible, excellent reproducibility of excitation, and recently, only a variety of patterns using a computer can be generated.

This gravure printing is a method in which the ink remaining in the groove formed by chamfering a doctor knife on a copper plate is transferred to a printing paper, and is printed in a process of repeating the transfer and drying by a plurality of guide rolls. , Can be finally wound up and finished.

The printing paper may be made of a material such as polyethylene terephthalate (PET), stretched polypropylene (OPP), or stretched polypropylene (CPP).

PET is a synthetic fiber obtained by polycondensation of terephthalic acid and ethylene glycol, and has better heat resistance than other synthetic fibers, and has excellent properties such as elastic recovery and wrinkle resistance.

It has excellent mechanical properties, thermal stability, high tensile strength, proper elongation, high transparency and gloss, and excellent barrier properties against oxygen and moisture.

The PET is used to satisfy the conditions of a density of 1.4 g/cm ² , a tensile elongation of 110%, and a temperature range of 70 to 150°C.

In addition, CPP (Poly-propylene) is a resin obtained by polymerizing propylene obtained by separation of petroleum naphtha or natural gas. Poly is a prefix, meaning "many", meaning that many propylene is combined.

This CPP is light weight, excellent in strength, and excellent in heat sealability and gas barrier properties. Functionalization is possible through AL deposition, and it is excellent in moisture resistance and heat resistance.

Such CPP is used to satisfy the conditions of 0.9 g/cm ² , tensile elongation 700%, use range temperature for general purpose 105° C. or less, CPR1 110° C. or less, and CPR 2 to 3 135° C. or less.

In addition, OPP (Oriented Poly-propylene) is a film made by stretching an unstretched polypropylene film in both longitudinal and transverse directions. It has better transparency, surface gloss than CPP, and good cold resistance and insulation. It is odorless, odorless and non-toxic, hygienic, and has low heat sealability.

The OPP is used to satisfy the conditions of 0.9 g/cm ² , tensile elongation 110%, and a temperature range of 50 to 110°C.

4. Lamination process steps

The lamination process step is a step of laminating the second paper and the printing paper by applying an adhesive to the surface of the printing paper obtained in the printing process step.

The adhesive provides chemical bonding strength using polyurethane, polyester, ethylene acrylic, or the like.

The lamination process step is performed by applying an adhesive to one side of the printing paper fed by using a plurality of rollers, and feeding the second paper from the other side so that the printing paper and the second paper are laminated by compression of a roller.

It is preferable that the finally laminated paper and the second paper are wound up and stored in the form of a roll.

This lamination process is performed at a speed of 70 to 80 m/min when conveyed through a plurality of rollers, and the Nip Roll provided for lamination has a temperature of 100°C.

In addition, when drying the adhesive applied to one side of the printing paper, the temperature of the high contrast is preferably made at a temperature of 70 to 90°C, for example, when the drying section is performed in 4 sections, 70°C and 80°C, respectively. It is desirable to have the temperature increased to 90°C, and then to be dried while having a section deteriorated to a temperature of 70°C. Accordingly, when the adhesive is applied, after solid drying, the curing of the adhesive is finally released, so that a strong lamination between the printing paper and the secondary paper can be achieved.

The second paper is fed as a blocking paper made of any one of aluminum (AL), PET or CPP material evaporation film; Or NY, PE, CPP, OPP, LPPE, and LLPPE materials. It means one or more paper feeds selected from among.

For example, the packaged goods of the food packaging pack according to the present invention, cotton, snacks, dried soup, sauce, refilled foods or retort foods can be made in various ways depending on the type.

At this time, in the case of the source, it is obvious to those skilled in the art that the feeding of NY, AL, and LLDPE can be used for PET printing paper, and detailed description will be omitted.

At this time, when two or more paper feeds are used, the lamination on them is to use the above-described laminating or conventional laminating technique.

NY, other than the above-mentioned PET, OPP, and CPP materials, is nylon, and is one of synthetic fibers woven with phenol, hydrogen, ammonia, etc. as a raw material, which is much tougher than conventional synthetic fibers and is widely used for cloth and industrial use. Such NY has high strength, good flexibility, and good heat resistance and cold resistance.

In addition, PE is polyethylene (Poly-Ethylene), which is made by polymerizing, ie, combining ethylene obtained by decomposition of petroleum naphtha or natural gas. This PE is lighter than water and has a property of melting like a candle when burned. It is difficult to print due to its small polarization in structure, but it has excellent strength and impact resistance.

It has high gas permeability and UV permeability, and is excellent in food oxidation deterioration and heat adhesion. In addition, various colors can be added.

In addition, the vaporized film forming the barrier paper (Metallized Film), by heating and evaporating the evaporation material in a high-vacuum state to condense on the surface of the base material to make a film, can utilize the metallic luster to enhance the metallic feel of the packaging, gas barrier properties and water vapor Very good barrier properties. Low light transmittance facilitates preservation of packaged contents.

As an example, the cross-sectional shape of the food packaging pack laminated through such a lamination process step may refer to FIG. 2 of the accompanying drawings.

Figure 2 shows a cross-section of a food packaging pack manufactured by the food packaging pack manufacturing method according to the present invention.

Fig. 2 of the accompanying drawings shows that the PET printing paper (①) and the second paper (②, ③, ④) are laminated using an adhesive (see the hatching area in Fig. 2), ② a blocking paper, ③ a NY paper, ④ It indicates PE or PP (OPP and CPP) paper.

5. Curing step

The curing step is a step of curing the paper obtained in the laminating process step at 40 to 55° C. for 2 to 5 days in the curing room (Aging Room).

6. Slitter process steps

The slitter process step is a step of cutting the paper cured by the curing step into a predetermined standard using a bobbing cutter.

At this time, description of the obvious matters in the slitter process, such as including a Line Follower Controler (LFC) with a sensing device that allows a constant adjustment of the line when cutting to a predetermined standard, will be omitted.

However, it is natural that the slitter process is also configured to release and transfer the lamination wound by a plurality of rollers, and to perform it using a pressure roller and a blade blade on one side.

The cut paper can be stacked on the upper side of a separate carrier.

However, depending on the design conditions, the roller contacted by the blade blade can be configured as shown in [Table 1] below.

As shown in [Table 1], the roller that the blade blade touches includes a first roller; A second roller; And a transport body.

Specifically, the first roller having the cross section of the'H' is configured to form the outer side of the roller, but has a concave groove on the outer surface along the circumferential direction,

A second roller which is inserted into the groove of the first roller and wraps the outer surface of the groove, and is covered with the first roller,

It is inserted into the groove of the first roller, the outer surface of the second roller, and includes a transport body having an inner surface configured to be spaced apart from the outer surface of the second roller.

At this time, groove portions are formed on both inner walls of the grooves of the first roller,

The second roller has a structure that extends longer along the outermost outer periphery, so that the extended region is inserted into and fixed to the groove of the first roller.

Accordingly, the second roller is movable in a state in which it is inserted into the first roller and can move left and right (based on [Table 1]) by a predetermined range.

In addition, the inner surface of the transport body and the outer surface of the second roller are spaced apart at regular intervals as described above, and are connected by a plurality of springs from the inner surface of the transport body to the outer surface of the second roller.

Accordingly, the conveying body can be transferred in the left and right directions within the groove of the first roller, while being connected to the second roller and the spring, while having separate mobility from the second roller, elastic force from the second roller It is possible to have the mobility.

That is, as the transfer body has the mobility that can be transported separately from the first roller and the second roller as described above, when the paper is transferred to the outer surface of the roller that the blade blade contacts, while being cut by the blade blade, the blade blade By, it is possible to reduce the damage to the outer surface of the roller contacting the blade blade, and to achieve the effect of preventing damage to the outer surface of the roller by double operation of the first roller and the conveying body.

According to this, it is expected that the cycle for maintenance or replacement of the rollers can be increased to improve equipment durability.

7. Finishing process steps

The finishing process step is a process of finishing the cut food packaging pack obtained through the slitter process step.

At this time, the meaning of the finishing of the step includes a re-enclosed process and a capping process, a stand pouch, a zipper stand pouch, a stand cap pouch, a T-shaped pouch, an M-shaped pouch, a three-way pouch, a zipper three-way pouch, It includes all processes to make the final shape such as an envelope-shaped pouch.
