Description

절취선을 가지는 포장재{The packing materials} Packing material having a perforation line

본 발명은 고출력 레이저 빔(Laser Beam)을 이용하여 쉽게 포장재를 개봉할 수 있도록 한 발명으로서, 특히 내용물을 보관한 포장재를 사용자가 편리하고 안전하게 개봉할 수 있도록 포장재의 한 부분에 레이저빔으로 절취선을 가지는 포장재에 관한 것이다.The present invention is an invention to easily open the packaging using a high power laser beam (Laser Beam), in particular to the user to conveniently and securely open the packaging containing the contents of the cutting line with a laser beam on a portion of the packaging material Eggplant relates to a packaging material.

일반적으로 빙과류나 스낵류 및 분말커피와 같은 제품의 소비 형태는 비닐 재질로 내용물을 낱개 포장하는 형태로 제공하는바, 상기 비닐 포장재 상, 하에는 톱니 형상을 가지도록 형성하여 소비자가 쉽게 개봉할 수 있도록 되어 있다.In general, consumption forms of products such as ice cream, snacks, and powdered coffee are provided in the form of individually packaging the contents of vinyl material, and are formed to have a sawtooth shape above and below the vinyl packaging material so that consumers can easily open them. It is.

그러나, 이러한 개봉수단은 소비자가 원하는 형태로 개봉되지 못하는 불편함 및 날카로운 톱니로 인하여 사용시 부주의에 의한 상처 발생 위험이 있어, 이러한 불편함을 해결하기 위하여 가위와 같은 절단 도구로 절단하여 포장재를 개봉하였다.However, the opening means has a risk of inadvertent injury due to inconvenientness and sharp teeth not opened in the form desired by the consumer, so that the packaging material was opened by cutting with a cutting tool such as scissors to solve this inconvenience. .

또한, 상기와 같은 개봉수단은 포장재의 접합부분에 형성됨으로써 포장재를 개봉할 때 상당한 힘을 주어야하므로 힘 조절이 되지 않는 어린이나 노약자가 사용 시에는 내용물이 쏟아지는 문제점이 발생하였다.In addition, since the opening means as described above is formed at the junction of the packaging material, a considerable force must be given when opening the packaging material, which causes problems in that the contents are spilled when the child or the elderly are not used to control the strength.

상기와 같은 문제점을 해결하기 위하여 최근에는 레이저빔으로 포장재에 절취선을 형성한 것이 실용신안등록 제268981호로 고안된바, 상기 고안을 살펴보면 별도 노치 부분과 레이저빔을 이용한 일정방향 이지 컷 부를 형성함으로써 포장재를 쉽게 개봉할 수 있는 고안이다.In order to solve the above problems, a cutting line formed on a packaging material with a laser beam has been devised as Utility Model Registration No. 268981. Looking at the above design, a packaging material is formed by forming a separate notch part and a predetermined easy cut part using a laser beam. It is a device that can be easily opened.

그러나, 상기 선등록 고안은 이지 컷이 전반적으로 형성되어 있어 이지 컷이 형성된 부분의 강도가 다른 부위보다 약함으로 포장작업이나 운반중에 외부의 충격으로 이지 컷부가 파괴되는 문제점이 발생할 가능성이 있다.However, the above-described pre-designed design is generally formed with easy cuts, and thus, the strength of the easy cut formed portion is weaker than that of other portions, which may cause a problem in which the easy cut portion is destroyed due to an external impact during packaging work or transportation.

특히, 분말형태의 내용물을 포장하는 경우에는 전체적인 이지 컷부가 있을 경우 포장 작업시 포장재가 끊어지는 현상이 나타나 내용물 포장이 안되는 문제점이 있고, 특히 약해진 이지 컷 부분 사이로 수분 및 가스가 유입되는 베리어성(Barrier)이 저하되어 분말상태의 내용물이 변질하는 문제점이 발생하였다.In particular, in the case of packaging the contents in the form of powder, there is a problem in that the packaging material is broken during the packaging operation when there is an overall easy cut part, and there is a problem in that the contents cannot be packed. Barrier) is deteriorated to cause the contents of the powder to be deteriorated.

상기와 같이 베리어성이 저하되는 또 다른 이유로서는 종래의 포장재 재질이 선등록 고안에 기재한 바와 같이 인쇄층인 OPP층, 접착층인 PE층, 베리어(Barrier) 층인 VmPET층, 열접착층인 PE층으로 형성되어 있는바, 상기 베리어층인 VmPET층이 일반 금속이 증착된 층으로서 고출력 레이저빔으로 이지 컷을 형성할 때 얇은 베리어 층인 VmPET층의 증착막이 파괴되어 투습 및 가스 차단력이 저하되므로 분말로 된 내용물이 훼손이 되는 문제점이 발생하였다.As another reason for the barrier property deterioration as described above, as the conventional packaging material is described in the prior registration design, the OPP layer as the printing layer, the PE layer as the adhesive layer, the VmPET layer as the barrier layer, and the PE layer as the thermal adhesive layer. When the barrier layer, the VmPET layer is a layer on which a general metal is deposited, and when the easy cut is formed by a high-power laser beam, the vapor deposition film of the thin barrier layer, the VmPET layer, is destroyed, and the moisture permeability and gas barrier force are lowered. This damaging problem occurred.

본 발명은 상기와 같은 종래에 선 등록된 고안에서 발생한 문제점을 해결하기 위한 것으로서, 레이저빔으로 이지 컷을 형성할 때 베리어 층이 파손되지 않는 안전한 구조를 개발하는 것을 목적으로 가진다.The present invention has been made to solve the problems caused by the above-described prior art, and has an object of developing a safe structure in which the barrier layer is not broken when forming an easy cut with a laser beam.

그리고, 본 발명의 부가적인 목적으로는 이지 컷 부분을 포장재의 전반적으로 형성하는 것이 아니라, 일정부분에만 이지 컷부를 형성함으로, 노치 부분 이 없어도 소비자가 쉽게 개봉할 수 있고 안정성을 확보하는 것을 목적으로 가진다.In addition, as an additional object of the present invention, the easy cut portion is not formed in the overall packaging material, but the easy cut portion is formed only at a predetermined portion, so that the consumer can easily open it without a notch portion and ensure stability. Have

상기와 같은 목적을 달성하기 위한 본 발명의 해결수단으로서는 베리어 층을 레이저 빔(Beam)이 반사하는 알루미늄 호일로 형성하여 고출력 레이저빔을 사용해도 베리어 층의 파손을 방지할 수 있고, 투습 및 가스차단성을 유지하고자 하는 것이 본 발명의 목적을 달성할 수 있는 것이다.As a solution of the present invention for achieving the above object, the barrier layer is formed of aluminum foil reflected by the laser beam (Beam) to prevent damage to the barrier layer even when using a high-power laser beam, moisture permeability and gas barrier properties To maintain is to achieve the object of the present invention.

또한, 부가적인 과제 해결수단으로서는 이지 컷이 형성되는 부위를 포장재의 양측부위와 후면 접합부위에 형성함으로 사용자가 포장재를 개봉할 때 양측에 형성된 이지 컷 부위를 통해서 쉽게 개봉할 수 있도록 하고 보관 및 운반상태에서는 파단강도를 높여 내용물의 훼손을 방지하도록 하여 본 발명의 부가적인 목적을 달성할 수 있는 것이다.In addition, as an additional problem solving means, by forming the part where the easy cut is formed on both sides and the rear junction of the packaging material so that the user can easily open through the easy cut formed on both sides when opening the packaging material, and the storage and transport state In to increase the breaking strength to prevent the damage of the contents to achieve the additional object of the present invention.

이때, 상기 이지 컷을 형성하는 본 발명의 다른 실시 예로서는 포장재의 후면에 형성되는 접합부에 이지 컷을 형성하여 사용자가 상기 후면에 형성된 이지 컷 부분을 통해서 포장재를 개방하도록 함으로 본 발명의 부가적인 목적을 달성할 수 있는 것이다.At this time, in another embodiment of the present invention to form the easy cut is to form an easy cut in the junction formed on the back of the packaging material to allow the user to open the packaging material through the easy cut portion formed on the back of the additional object of the present invention It can be achieved.

상기와 같은 목적과 해결과제를 가지는 본 발명은 레이저빔으로 개봉이 용이하게 이지 컷을 형성하였을 때 발생하는 파단강도가 약해지는 것을 방지하고, 포장재를 생산 또는 운반도중에 이지 컷 부분에 대한 파단 강도를 높여서 포장재의 파손을 방지하고, 고출력 레이저빔을 사용해도 베리어성의 저하가 없는 재질을 사용함으로 이지 컷 부위를 통하여 수분 및 가스가 포장재 내부로 침투하여 제품이 변질되는 것을 방지할 수 있는 발명이다.The present invention having the above object and problem prevents the breaking strength generated when the easy cut is easily formed with a laser beam, and reduces the breaking strength of the easy cut portion during the production or transportation of the packaging material. It is an invention that can prevent the damage to the packaging material by increasing the packaging material, and prevents the product from being deteriorated by penetration of moisture and gas into the packaging material through the easy cut part by using a material that does not deteriorate the barrier property even when using a high-power laser beam.

이하, 본 발명을 실현하기 위한 구체적인 내용을 첨부된 도면에 도시한 바와 같은 실시 예를 통해서 상세히 설명하면 다음과 같다.Hereinafter, with reference to the embodiments as shown in the accompanying drawings the specific content for realizing the present invention will be described in detail.

도 1은 본 발명의 실시 예를 통하여 실현한 포장재를 도시한 전개 사시도이고, 도 2는 본 발명의 실시 예에 사용되는 비닐지의 전개 사시도이며, 도 3은 본 발명의 실시 예를 실현하기 위하여 사용되는 레이저 가공원리를 도시한 개략도이고, 도 4는 본 발명의 실시 예를 실현하기 위한 포장지의 구조를 나타낸 단면도이며, 도 5는 본 발명과 종래 제품의 파단강도 및 수분 투과율을 비교한 비교도이다.1 is an exploded perspective view showing a packaging material realized through an embodiment of the present invention, Figure 2 is an exploded perspective view of a plastic sheet used in the embodiment of the present invention, Figure 3 is used to realize an embodiment of the present invention Figure 4 is a schematic view showing the laser processing principle, Figure 4 is a cross-sectional view showing the structure of the wrapping paper for realizing an embodiment of the present invention, Figure 5 is a comparison of the breaking strength and moisture transmittance of the present invention and the conventional product .

따라서, 본 발명은 도 1과 도 2에 도시한 바와 같이 내용물인 제품을 담기 위한 포장재(1)는 전개된 비닐지(101)를 제품의 크기에 맞추어 일정한 크기로 사각 재단을 하고, 상기 재단된 비닐지(101)의 양 측면을 서로 접착하여 접합부(120)를 형성함으로 원통 형상의 몸체(100)를 형성한 다음 몸체(100)의 상, 하부를 다시 접착하여 상, 하의 접합부(121)(122)를 형성함으로 포장재(1)를 완성한다.Therefore, the present invention is a packaging material 1 for containing the product as shown in Figures 1 and 2 is made of a square cut to a certain size according to the size of the expanded plastic paper 101, the cut Both sides of the plastic paper 101 are bonded to each other to form a joint portion 120 to form a cylindrical body 100 and then the upper and lower joints of the body 100 again to bond the upper and lower joints 121 ( 122) is completed to complete the packaging material (1).

이때, 가루커피와 같은 분말재질의 내용물을 포장할 때에는 몸체(100)를 형성하기 위한 접합부(120)를 형성한 다음 몸체(100)의 하부 접합부(122)를 형성하고 몸체(100)의 내부에 내용물을 수납한 후 상부 접합부(121)를 형성하는 것이다.At this time, when packaging the contents of the powder material, such as powdered coffee to form a junction portion 120 for forming the body 100 and then to form a lower junction portion 122 of the body 100 and inside the body 100 After storing the contents to form the upper junction (121).

그리고, 상기 포장재(1)를 쉽게 절취하기 위하여 레이저빔으로 형성하는 이지 컷(110)을 형성하기 위해서는 몸체(100)의 상, 하부 중 어느 한 곳에 이지 컷(110)을 형성하는 것이 바람직한 것으로 바람직하게는 포장재(1)의 표면에 인쇄된 상태를 고려하여 상부에 형성한다.In addition, in order to form the easy cut 110 formed by the laser beam to easily cut the packaging material 1, it is preferable to form the easy cut 110 on any one of the upper and lower portions of the body 100. Preferably it is formed in the upper part in consideration of the state printed on the surface of the packaging material (1).

따라서, 본 발명을 실현하기 위한 실시 예로 제시된 구체적인 내용으로서는 상기와 같이 이지 컷(110)을 형성할 때 몸체(100)의 상부에 전체적으로 형성하는 것이 아니라 몸체(100)를 형성하기 위하여 배면에 형성되는 접합부(120)와 몸체(100)를 형성하였을 때 양측에 해당하는 부위만을 이지 컷(110)으로 형성한다.Therefore, as the specific contents presented as an embodiment for realizing the present invention, when the easy cut 110 is formed as described above, it is formed on the rear surface to form the body 100, rather than being formed entirely on the upper part of the body 100. When the junction portion 120 and the body 100 are formed, only the portions corresponding to both sides are formed by the easy cut 110.

이는 포장재(1)를 개봉할 때 사용자가 포장재(1)의 상부를 잡아당기면 몸체(100)의 후면 접합부(120)와 양측에 형성된 이지 컷(110)을 통해서 몸체(100)의 상부가 개봉되는 것이고, 사용자가 몸체(100)의 상부 측면을 잡아당겨도 몸체(100)의 측면에 형성된 이지 컷(110)을 통해 개봉되는 것이다.When the user pulls the upper part of the packing material 1 when opening the packing material 1, the upper part of the body 100 is opened through the easy cut 110 formed on both sides of the back joint 120 and both sides of the body 100. Even if the user pulls the upper side of the body 100 is to be opened through the easy cut 110 formed on the side of the body 100.

그리고, 상기와 같이 포장재(1)의 몸체(100) 상부를 개봉하기 위한 다른 실시 예로서는 이지 컷(110)을 몸체(100)의 양측면에 형성하지 않고 몸체(100)의 후 면에 형성된 접합부(120)에만 형성하여도 무방한 것으로서, 이 경우에는 사용자가 몸체(100)의 후방에 형성된 이지 컷(110)을 통해서 몸체(100)의 상부를 개봉하는 것이다.In addition, as another embodiment for opening the upper portion of the body 100 of the packaging material 1 as described above, the joint portion 120 formed on the rear surface of the body 100 without forming the easy cut 110 on both sides of the body 100. ) May be formed only in this case, in this case, the user opens the upper portion of the body 100 through an easy cut 110 formed at the rear of the body 100.

이때, 상기와 같이 몸체(100)에 이지 컷(110)을 형성하기 위한 레이저 가공방법으로서는 도 3에 도시한 바와 같이 레이저 발생기(130)에서 레이저가 발생하면 헤드(131)가 좌, 우로 움직이면서 비닐지(101)에 레이저빔을 조사하여 이지 컷(110)을 형성하는바, 레이저빔을 연속해서 조사하는 것이 아니라 일정한 간격을 두고 조사하게 하면 몸체(100)의 후면에 형성되는 접착부위와 몸체(100)의 양측에 해당하는 부위만 레이저빔을 조사하여 이지 컷(110)이 형성된다.At this time, as the laser processing method for forming the easy cut 110 in the body 100 as described above, when the laser is generated in the laser generator 130 as shown in Figure 3, the head 131 moves to the left, right and vinyl The laser beam is applied to the paper 101 to form the easy cut 110. Instead of irradiating the laser beam continuously and irradiating at regular intervals, the adhesive portion and the body formed on the rear surface of the body 100 The easy cut 110 is formed by irradiating a laser beam only on portions corresponding to both sides of the 100.

또한, 이지 컷(110)을 형성할 때 레이저빔이 비닐지(101)를 완전하게 통과하는 것이 아니라 비닐지(101)를 이루는 여러 층 중 베리어층의 상부인 인쇄층만 가공하도록 레이저빔의 가공깊이를 조절함으로 비닐지(101)의 표면에 이지 컷(110)을 형성한다.In addition, when forming the easy cut 110, the laser beam does not completely pass through the plastic sheet 101, but rather the processing of the laser beam so as to process only the printing layer, which is the upper part of the barrier layer, among the various layers forming the plastic sheet 101. By controlling the depth, the easy cut 110 is formed on the surface of the plastic sheet 101.

그러므로, 본 발명에 의하여 제시되는 비닐지(101)의 구조를 도 4를 참조하여 설명하면 다음과 같다.Therefore, the structure of the plastic paper 101 proposed by the present invention will be described with reference to FIG.

첨부된 도면 도 4에서와 같이 본 발명에 의하여 구현되는 포장재에 사용되는 비닐지(101)는 상부에서부터 인쇄층인 PET층(200), 접착층인 PE층(210), 베리어(Barrier)층인 알루미늄 호일층(220), 열접착층인 PE층(230) 및 구김방지 및 형태유지를 위한 LLD층(240)이 순차적으로 적층되어 구성되는 것으로서, 상기 알루미늄 호일층(220)의 상부와 하부에 각각 접착층인 PE층(210)(230)을 형성함이 바람직하다.The attached plastic sheet 101 used in the packaging material implemented by the present invention as shown in Figure 4 is an aluminum foil that is a PET layer 200, an adhesive layer PE layer 210, a barrier layer (Barrier) layer from the top A layer 220, a PE layer 230, which is a heat-adhesive layer, and an LLD layer 240 for preventing wrinkles and maintaining shape, are sequentially stacked, and each of the adhesive layers is formed on top and bottom of the aluminum foil layer 220, respectively. Preferably, the PE layers 210 and 230 are formed.

이때, 상기 베리어층인 알루미늄 호일층(220)은 레이저빔을 반사하게 됨으 로 레이저의 가공깊이가 설정된 깊이보다 깊게 가공될 경우에도 알루미늄 호일층(220)이 레이저빔을 반사하여 알루미늄 호일층(220)의 훼손이 발생하지 않는 것이다.In this case, the barrier layer aluminum foil layer 220 reflects the laser beam, so that the aluminum foil layer 220 reflects the laser beam even when the processing depth of the laser is processed deeper than the set depth. ) Is not damaged.

그러므로, 종래 이지 컷부가 없는 포장재에 사용된 비닐지와 본 발명에 의한 비닐지에 대하여 제품 물성을 살펴보면 도 5에 도시한 바와 같이 포장재(1)의 파단강도 즉, 포장재(1)가 이지 컷(110)을 통하여 파단되는 강도로서는 종래의 포장재는 9.5kg/15mm 인 것에 반하여 본 발명에 사용된 포장재(1)는 약 4.0kg/15mm 이하 인 것을 알 수 있어 포장재(1)의 개봉이 종래보다 쉽게 할 수 있는 것이다.Therefore, when looking at the product properties of the vinyl paper and the plastic paper according to the present invention used in the conventional packaging material without the easy cut portion, the breaking strength of the packaging material 1, that is, the packaging material 1 is easy cut 110 As the strength broken through), the conventional packaging material is 9.5kg / 15mm, whereas the packaging material 1 used in the present invention is about 4.0kg / 15mm or less, so that the opening of the packaging material 1 is easier than before. It can be.

그리고, 제품의 변질을 방지하는데 중요한 요인인 수분 투과도를 비교하여보면 종래 포장재는 1.0g/m2.1atm 24hrs 이하이고, 본 발명의 포장재(1)는 0g/m2.1atm 24hrs에 근접한 것임 알 수 있어 이지 컷(110)을 통한 베리어성이 본 발명에서는 완전히 차단된 것임을 알 수 있다.In addition, when comparing the moisture permeability, which is an important factor in preventing the deterioration of the product, it can be seen that the conventional packaging material is 1.0g / m2.1atm 24hrs or less, and the packaging material 1 of the present invention is close to 0g / m2.1atm 24hrs. It can be seen that the barrier property through the easy cut 110 is completely blocked in the present invention.

그러므로 본 발명에 의한 포장재(1)는 종래에 이지 컷을 형성한 포장재와는 달리 포장재(1)의 몸체(100)가 용이하게 개봉되도록 하고 이지 컷(110)을 형성한 일정 부위를 통해서 발생하는 파단강도의 약화와 베리어성 약화를 방지하여 제품의 변질을 방지할 수 있는 발명이다.Therefore, the packaging material 1 according to the present invention is different from the conventional packaging material in which the easy cut is formed so that the body 100 of the packaging material 1 is easily opened and formed through a predetermined portion in which the easy cut 110 is formed. It is an invention that can prevent the deterioration of the product by preventing the weakening of the break strength and the weakening of the barrier property.
