Description

The vinyl packing paper and the manufacturing method thereof in which recycle facilitates}

The present invention is a recycling that can be disposed of by easily separating the separation sheet having a high recycling grade from the printing sheet having a relatively low recycling grade through incision when disposing of a plastic wrapper composed of a printing sheet and a separation sheet having different recycling grades It relates to this easy-to-use plastic wrapper.

In recent years, packaging technology for packaging goods or food (hereinafter referred to as contents) is rapidly developing thanks to the development of printing technology. However, plastic packaging materials molded with synthetic resin for the purpose of extending the shelf life of food are still mainly used.

Printing is performed on the outer surface of these plastic packaging materials to indicate information on the contents contained therein. In particular, when the contents are food, harmful substances caused by printing and printing do not affect the contents, as well as ease of adhesion and distribution. Due to the extension of the deadline, the inner sheet is laminated (adhesive) on the inner surface of the printed outer sheet and used as a plastic packaging material in the form of an envelope.

For example, the inner sheet is laminated on the inner surface of the outer sheet using a recyclable PP (polypropylene: polypropylene) or PE (polyethylene: polyethylene) resin, and the outer sheet uses a synthetic resin of PET (polyethylene terephthalate) or nylon Thus, the plastic packaging material is molded.

In such a conventional plastic packaging material, the contents are accommodated inside the outer sheet and inner sheet made of synthetic resins of different recycling grades laminated to each other. Since synthetic resins that are low or not recyclable are disposed of in a laminated state that cannot be separated from each other, they cannot be recycled and thus depend on incineration, which causes environmental pollution.

In recent years, in order to solve this conventional problem, an embossed air layer is formed between the outer sheet and the inner sheet to enable mutual separation or to reduce environmental pollution through a device that separates the outer sheet and the inner sheet at a separate cost recycling methods are selected for

However, this prior art has a problem in that practical use is remarkably low due to a delay in working time, as well as a defect rate and expensive equipment due to a separate process for forming the air layer. In this case, not only an economic burden, but also a problem arises that the recovery rate of the recyclable inner sheet is low.

In order to solve the above-mentioned conventional problems, the present invention is not economically burdensome, and at the same time secures ease of mass production through simplification of the process, and at the same time significantly lowers the defect rate, and has a high recovery rate of inner sheets for recycling. The purpose is to provide

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

Hereinafter, with reference to the accompanying drawings, a plastic wrapping paper (hereinafter, simply referred to as 'vinyl wrapping paper') which is easy to recycle according to the present invention will be described in detail. Prior to the description, below, the present invention, the plastic wrapping paper 1, is illustratively used as a packaging pack for food packaging in which food (contents) that can be distributed is accommodated therein in order to clearly understand the gist, but this is only one embodiment Note that the present invention is not limited thereto.

First, as shown in FIGS. 1 and 2, the plastic wrapping paper 1 according to the present invention largely includes a printing sheet 100 and a separation sheet 300, and the printing sheet 100 and the separation sheet ( 300) may have a structure in which each is wound in the form of a roll and supplied in one direction by the rotation of the driving motor (see FIG. 3 ).

In more detail, as shown in FIG. 2 , the printing sheet 100 is adhered to a separation sheet 300 to be described later to form an adhesive sheet, but the printing sheet 100 adhered to the separation sheet 300 . ), the printing surface 110, which is the outer surface, is printed for advertising of food, etc.

For example, the printing sheet 100 is formed in the shape of a plate as a whole using a synthetic resin such as nylon or PET (polyethylene terephthalate), and the adhesive (G) is applied to the printing surface 110, which is the side on which the adhesive (G:Glue) is applied. ) is printed on the contents before being applied, so that the printing can be seen from the outer surface of the print sheet 100 .

Here, as shown in addition to printing, the adhesive G by the roller member 200 is applied to the printing surface 110 except for the blank 120 having a predetermined area and the blank 120 on the printing surface 110 . And, the blank portion 120 may be formed in one pair or adjacent to each other in the longitudinal direction (horizontal direction in the drawing) in comparison with the interview of the printing sheet 100, and below, a pair of the blank portion ( 120) will be described as an example. In an embodiment of the present invention, the blank portion 120 may mean a surface to which the adhesive G is not applied among the printing surfaces.

As shown in FIGS. 3 and 4, the adhesive G supplied from the adhesive supply means 10 is applied to the outer surface of the adhesive G to be applied to the printing sheet 100, and the applied adhesive G is The application is made through the roller members 200 that face each other so that they can be applied to the printing surface 110 .

To this end, as shown in Fig. 4, the roller member 200 in the present invention is a conventional roller 210 and the roller 210 rotatably coupled to a printing device having an adhesive supply means (not shown). It includes a sleeve 220 formed on the outer surface.

Here, as shown, the sleeve 220 has a structure surrounding the circumferential surface of the roller 210 , and an application surface that faces the printing surface 110 so that the adhesive G can be applied to the printing surface 110 . At least one space portion 223 formed between the application surface 221 is formed according to the number of blank portions 120 to be formed on the 221 and the printing surface 110 .

That is, the sleeve 220 is formed so that the application surface 221 to which the adhesive G supplied from the adhesive supply means (not shown) is supplied to the outer surface protrudes along the circumferential surface of the roller 210 in a embossed shape. The back space portion 223 forms an intaglio, non-protruding shape, so that the adhesive G and the blank portion 120 are simultaneously formed on the printing surface 110 through the rotation of the roller 210 . .

And, as shown in FIGS. 5 and 6 , the separation sheet 300 is adhered (laminated) to be superimposed on the printing surface 110 . The separation sheet 300 is adhered to the surface to which the adhesive G is applied among the surfaces of the printing sheet 100 , and is not adhered to the blank portion 120 . Here, the surface to which the printing sheet 100 and the separation sheet 300 are adhered is assumed to be an adhesive surface.

The adhesion of the separation sheet 300 is to prevent toxic substances from being absorbed by printing, and the partial adhesion of the separation sheet 300 is easily separated from the printing sheet 100 at the time of disposal for recycling for convenience of recycling. is to provide

For example, the separation sheet 300 is formed in the shape of a plate as a whole using a synthetic resin of PE (polyethylene) or PP (polypropylene), which is classified into grades that are easy to recycle, and a pair of blank parts 120 It is adhered to the printing surface 110 to which the adhesive G is applied so as to be covered.

At this time, it is preferable that the total area D2 of the separation sheet 300 is formed to have the same area as the area D1 or D1' of the printing sheet 100 so that the adhesive sheet is formed.

Thus, the separation sheet 300 is integrally bonded with the printing sheet 100 in the portion where the applied adhesive (G) and each other face each other, but is separated from the printing sheet 100 in the area where the blank portion 120 is formed ( As the plastic wrapping paper 1 is cut in various directions to form a raised), the separation between the separation sheet 300 and the printing sheet 100 can easily function (see FIGS. 10 and 11 ).

In order to maximize these advantages, the printing sheet 100 and the separation sheet 300 may be made of materials having different reaction temperatures by thermal bonding (H/S).

That is, the separation sheet 300 uses a material having a lower adhesive reaction temperature by heat than the printing sheet 100 , and even when heat is applied from the outer surface of the printing sheet 100 in the mutually bonded grounding sheet state, within the margin 120 . Adhesion between the printing sheet 100 and the separation sheet 300 is prevented, but only the separation sheets 300 superimposed on each other can be thermally bonded by the heat.

The area where the thermal bonding is performed includes a surface on which the adhesive G is applied, and may further include as much as an area extended by a predetermined thickness from each side of the blank portion 120 . In FIG. 10 , the surface on which the adhesive G is applied and the heat-adhesive surface H/S in the blank portion 120 extended to a predetermined thickness are indicated in different ways.

In summary, thermal bonding is performed between the separation sheets 300 , and the area extends from each side of the separation sheet 300 to the inside of the blank 120 by a predetermined thickness in addition to the surface on which the adhesive G is applied. is made across

The surface on which thermal bonding between the separation sheets is made will be referred to as a thermal bonding surface. As defined in the present invention, the area of the thermal bonding surface is equal to or larger than that of the bonding surface.

On the other hand, the separation sheet 300 in the present invention, as shown in FIGS. 5 to 7, prevents the external loss of the contents accommodated after the separation sheet 300 is separated from the printing sheet 100, or the contents It may further include any one of the opening and closing means 310 or the bundle band 320 to be selectively opened and closed when using.

Here, the opening and closing means 310, as shown in FIGS. 5 and 6, is a pair of blank portions ( 120) is adhered to the upper part, and after bonding, the separation sheet 300 is adhered to be covered, and the opening and closing means 310 is completed at the same time as the adhesive sheet is formed, and the opening and closing means 310 is a pair of It includes a coupling protrusion 311 attached to any one of the blank parts 120 and a coupling groove 313 attached to the other blank part 120 .

The coupling protrusion 311 and the coupling groove 313 have a normal zipper lock structure in which male and female types are separated and coupled, and the opening and closing means 310 is a pair of plastic wrapping paper (1) formed symmetrically on both sides of each other. After being cut along the incision line (L) arbitrarily connected to the easy-cut 130 of the can be exposed to the outside.

The incision line L may be set between the boundary between the adhesive G application surface and the blank portion 120 or the thermal bonding surface formed on the blank portion 120 from the boundary. A plurality of perforations in the form of dotted lines may be formed in the incision line (L) along the incision line (L) to facilitate incision.

When the incision is made along the incision line (L), only the separation sheet 300 disposed inside the blank portion 120 of the separation sheet 300 remains. Since the separation sheet 300 disposed inside the blank portion 120 does not have a surface bonded to the printing sheet 100 , it is completely separated from the printing sheet 100 to facilitate recycling (see FIG. 10 ).

In addition, the separation sheet 300 cut along the incision line (L) can more easily store the contents by the opening/closing means 310 or the bundle band 320 .

On the outer surface of the separation sheet 300, a cutting hole 321 having a predetermined length is formed in advance so that the coupling protrusion 311 or the coupling groove 313 is exposed to the outside of the separation sheet 300 and can be detachably coupled to each other. It is preferable to be

In addition, as shown in FIG. 7 , the bundle band 320 includes an incision hole 321 and a band 323 , but the incision hole 321 allows the separation sheet 300 to be adhered to the printing sheet 100 . A plurality of incisions are formed at predetermined intervals on the upper part before, and the band 323 is inserted through the plurality of incision holes 321 in a zigzag manner to have a ring shape as a whole so that both ends are connected to each other. is glued

Thus, when using the bundle band 320, after the separation sheet 300 is separated from the print sheet 100, the band 323 connected in a ring shape is cut and the cut both ends are pulled in one direction, similar to a lucky bag As shown in the shape of the above, the upper part of the separation sheet 300 is retracted without loss of contents, and the upper part that is opened can be tied and used.

Hereinafter, with reference to the accompanying drawings, it will be described in detail with respect to the manufacturing method of the easily recyclable plastic wrapping paper (hereinafter referred to as 'manufacturing method') according to the present invention.

First, as shown in Figure 12, the manufacturing method (2) according to the present invention is largely 1) supplied in the form of a roll (Roll), a blank in the printing sheet 100 having a printing surface 110 made of printing on one side Step (S10) of applying the adhesive (G) to a part of the printing surface 110 so that the portion 120 is formed (S10), and 2) supplied in the form of a roll so that the blank portion 120 is covered Step (S20) of bonding the printing sheet 100 and the separation sheet 300 to form an adhesive sheet;紙) forming a laminated sheet (S30), 4) performing thermal bonding to a pair of laminated sheets to form a plastic packaging sheet (S40), and 5) cutting the vinyl packaging sheet to make a plastic wrapping paper for each unit and (S50) of obtaining (1).

More specifically, step 1) is a step of applying the adhesive G having the blank portion 120 on the printing surface 110 of the printing sheet 100 using the roller member 200 .

For example, referring to FIGS. 2 and 3 , when the printing sheet 100 wound in the form of a roll on the outer surface of the rotatable roller is unwound, the printing surface 110 of the printing sheet 100 is in contact with the application surface 221 . At the same time as the adhesive (G) is applied to the space portion 223 is formed to make a non-contact to form a pair of blank portions (120).

Of course, before forming the adhesive (G) and the blank portion 120 on the printing surface 110, a pre-processing used to advertise the contents is used.

Meanwhile, in the present invention, a band processing step of forming the bundle band 320 may be further included as step 1-1) after step 1) described above.

For example, the bundle band 320 is formed by inserting a band 323 through a zigzag method through a plurality of incision holes 321 formed on the upper portion of the separation sheet 300 having a state prior to being adhered to the printing sheet 100 ( see Fig. 7).

At this time, it is preferable that the location of the bundle band 320 is positioned within the blank portion 120 and at the same time formed at a location where interference does not occur during thermal bonding to the separation sheet 300 .

And, the step 2) is to obtain an adhesive sheet that prevents harmful substances used for printing from being absorbed in the contents accommodated by adhering the separation sheet 300 to the printing sheet 100 obtained in step 1) described above. is a step for

To this end, the separation sheet 300 is surfaced so as to be superimposed on the printing surface 110 of the printing sheet 100 and is adhered to the printing sheet 100 in the area where the adhesive G is applied (see FIG. 5 ).

Meanwhile, in the present invention, after step 2), step 2-1) may further include a zipper processing step of forming the opening/closing means 310 on the outer surface of the separation sheet 300 adhered to the printing surface 110 ( 5 and 6).

For example, the opening/closing means 310 including the coupling protrusion 311 and the coupling groove 313 is formed adjacent to each other in the longitudinal direction on the outer surface of the printing sheet 300 forming an adhesive sheet continuous in the transverse direction, as shown. A coupling protrusion 311 and a coupling groove 313 are respectively attached to be positioned within the pair of blank portions 120, and are exposed to the outside through the cutout 321 of the separation sheet 300 covered thereon, which will be described later. When forming the laminated sheet, it can be detachably coupled in a male and female form.

At this time, the body of the opening/closing means 310 that interfaces with the separation sheet 300 is made of the same material as the separation sheet 300, or another adhesive (G) is used for the portion to be interviewed so that it can be connected to each other. It is desirable to ensure that the confidentiality can be maintained after the contents are accommodated.

And, 3) step (S30) is a step for allowing a laminated sheet to be obtained using a pair of adhesive sheets obtained through the above-described step 2) (see FIG. 8 ).

For example, in step 3), as shown in the figure, the coupling protrusions 311 constituting the opening/closing means 310 are attached to a plurality of adhesive sheet portions in the transverse direction (vertical direction in the drawing) and the coupling grooves 313 are transversely After obtaining a pair of adhesive sheets by making an incision along the incision line (distinct from the incision line in FIG. 6 L, FIGS. 9 and 10) so that the remaining adhesive sheet parts adhered to each other are divided, the pair of the adhesive sheet is pressed to each other by a roller, etc. to obtain a laminated sheet in which the coupling protrusion 311 and the coupling groove 313 are coupled to each other (refer to FIGS. 6 and 8).

At this time, a pair of adhesive sheets cut into halves are recovered to be wound in a roll form, respectively, but when obtaining a laminated sheet, a pair of folding sheets are not adhered to each other so that the laminated sheet can be obtained so as to have a laminated structure it is preferable

Of course, when the opening and closing means 310 is provided on a pair of ground sheets, the laminated sheet can be obtained in a state in which the opening and closing means 310 are combined.

And, 4) step (S40) performs thermal bonding on the laminated sheet obtained in step 3) so that a pair of separation sheets 300 having a laminated structure can be adhered to each other, so that the contents can be accommodated in an envelope shape This is a step for forming a plastic packaging sheet of (see FIG. 9).

To this end, thermal bonding is performed by thermal bonding by high frequency or the like on the outer surface of the printing sheet 100, that is, on the side on which the printing is not formed, so that a pair of separation sheets 300 having the same material are adhered to each other and the opening and closing means inside it (310) so that the receiving space for accommodating the contents in the lower direction can be formed.

Thus, the printing sheet 100 having a higher thermal bonding reaction temperature than the separation sheet 300 adheres only to the separation sheet 300 of the same material in response to the temperature when thermal bonding is performed on the outer surface of the printing sheet 100 . this will be done

At this time, in step 4), when performing thermal bonding, the remaining parts except for the upper part of the opening and closing means 310 adhered to the separation sheet 300 are heat-bonded in advance, and then the contents are passed through the opened upper part where the thermal bonding is not made. After accommodating the upper part opened can be thermally bonded secondary.

Finally, in step 5) (S50), in the present invention, the plastic packaging sheet obtained through step 4) is cut along the incision line (differentiated from the incision line in FIG. 9 L, FIGS. 6 and 10) for each unit This is a step for obtaining the required plastic wrapping paper (1).

At this time, after step 5), in step 6), a plurality of easy cuts 130 are perforated at one or both sides of the plastic wrapping paper 1, as well as a border-shaped joint connected between the blank portion 120 and the heat bonding line. It is preferable to further include an easy-cut forming step.

As shown in FIG. 10, the easy-cut 130 may be formed in at least one of the portions where each incision line L and each side of the plastic wrapping paper 1 meet, and may be formed in a triangular shape directed in the incision direction. there is. The easy-cut 130 may also be formed in a diamond (rhombus) shape at a point where a plurality of incision lines L meet. The diamond-shaped easy-cut 130 is set to have a triangular-shaped easy-cut 130 shape when a part of any one of the upper, lower, left, and right sides is cut with the help of the easy-cut 130 .

In FIG. 10, the cut-out line L is defined as a line through which the combination of the printing sheet and the separation sheet 300 is separated while the bonding between the pair of separation sheets 300 is maintained when the laminated sheet is cut. can Spatially, the incision line L is defined within the area where only the thermal bonding surface exists from the inner boundary where the bonding surface and the thermal bonding surface are superimposed. When the incision line (L) is defined in this way, when the laminated sheet is cut along the incision line (L), the cut inner separation sheet 300 is completely separated from the print sheet 100 and has a thermal adhesive surface on the edge This remains and the contents are in a state that can be preserved.

On the other hand, the printing surface on the printing sheet 100 may include a visual display of the cut-out line among the printed contents.

The plastic wrapping paper 1 manufactured in the plurality of steps includes a blank portion 120 by cutting with scissors along a plurality of incision lines L on which the easy-cut 130 is formed, as shown at the time of disposal. The waste sheet can be obtained through cutting, and the waste sheet can be separated from the separation sheet 300, which is a material with a high recycling grade, and the printed sheet 100, which is a material with a low grade, so that it is possible to minimize environmental pollution It becomes possible to easily separate the graded recycled sheet (refer to FIGS. 10 and 11).

As described above, the plastic wrapping paper 1 in the present invention is differentiated from the prior art by cutting along the incision line L set so that only the material of the separation sheet 300 is separated during separation for recycling to separate the separation sheet 300 ) is separated from the printing sheet 100, so that selective separation and collection is possible depending on the recycling grade, so the recovery rate of recyclable resin is high, contributing to the prevention of environmental pollution, and at the same time simplification of the process and mass production with a small quantity The effect of ensuring ease of use is realized.
