자동라벨기용 이형필름 및 이의 제조방법{Release film for automatic labeller and preparing method thereof}Release film for automatic labeling machine and manufacturing method thereof {Release film for automatic labeller and preparing method

본 발명은 자동라벨기용 이형필름 및 이의 제조방법에 관한 것으로, 좀 더 구체적으로는 폴리프로필렌 또는 폴리에틸렌테레프탈레이트 기재 필름의 상면에 실리콘 수지를 증착시킨 다음, 필름의 하면에 특수 코팅액을 처리하여 얻어진 이형필름 및 이의 제조방법에 관한 것이다. The present invention relates to a release film for an automatic labeling machine and a method for manufacturing the same, more specifically, a release obtained by depositing a silicone resin on the upper surface of a polypropylene or polyethylene terephthalate base film, and then treating a special coating liquid on the lower surface of the film. It relates to a film and a method for producing the same.

이형지(release paper) 또는 이형필름은 점착테이프의 점착면을 보호하기 위해 뒷면에 붙이는 종이 또는 필름으로, 점착테이프, 감압접착지, 라벨, 실 등의 점착면에 접촉시켜 면을 보호하고, 사용시에는 벗겨내어 목적을 달성할 수 있도록 표면가공이 되어 있다.Release paper or release film is a paper or film that is attached to the back side to protect the adhesive side of the adhesive tape.It protects the surface by contacting the adhesive side such as adhesive tape, pressure-sensitive adhesive paper, labels, and seals. The surface is processed to peel off and achieve the purpose.

일반적으로 이형지로 사용되는 원지로는 그라싱지(glassine), 크라프트지(kraft), 필름 등이 있고, 박리처리제로는 실리콘이 사용되는 것이 일반적이다. Generally, a base paper used as a release paper includes glassine, kraft paper, a film, and the like, and silicon is generally used as a release treatment agent.

종래의 자동라벨기용 이형재로는 일반적으로 백색 또는 옥색의 그라싱지 또는 크라프트지를 기재로 하고, 그 상면에 실리콘으로 이형처리하여 사용한다. 그러나, 그라싱지는 국내 생산이 불가한 품목으로 전량 수입에 의존하고 있어 그 구매원가가 1톤당 200만원이상으로 매우 고가이고, 자동라벨기에 적용된 후에 남은 그라싱지는 전량 폐기처리되어 그 재생이 불가능하며, 인장강도면에서도 종이류의 한계를 벗어나지 못하므로 라벨기의 고인장에 의해 파열되는 경우가 빈번히 발생하고 있다. As a release material for a conventional automatic labeling machine, generally, a white or aqua colored grazing paper or kraft paper is used as a base material, and the upper surface thereof is used by release treatment with silicon. However, since the grazing paper is an item that cannot be produced domestically, it depends on the total imports, so the purchase cost is very expensive, more than 2 million won per ton, and the remaining grazing paper after the application of the automatic labeling machine is discarded and cannot be recycled. In addition, even in terms of tensile strength, it is frequently broken due to the high tension of the labeling machine.

또한, 크라프트지는 그 위에 직접 실리콘 코팅을 할 수 없고, 폴리라미(polylami) 또는 클레이(clay) 코팅을 한 후에 실리콘을 증착시키는 것이 가능하므로 비용면에서 경제적이지 못하며, 인장강도 또한 종이류의 한계를 벗어나지 못하여 자동라벨기를 통과시 파열되는 경우가 있다.In addition, kraft paper is not directly coated on it, and it is not economical in terms of cost because it is possible to deposit silicon after polylami or clay coating, and the tensile strength does not exceed the limits of paper. It may be broken when passing through automatic labeling machine.

한편, 자동라벨기에 적용되는 이형필름에 관한 종래기술을 살펴보면, 한국 공개특허 제1997-20424호에서는 2축연신 폴리프로필렌에 실리콘을 처리하여 폴리에틸렌테레프탈레이트나 그라싱지를 대체하여 이형재로 사용하는 것을 개시하고 있으나, 그 효과를 증명할 수 있는 데이터를 나타내지 않고 본 발명에서 사용한 바와 같은 특수 코팅액으로 코팅처리하여 재활용도 및 인장강도를 높이는 기술에 대한 기재는 없다. On the other hand, looking at the prior art related to the release film applied to the automatic labeling machine, Korean Unexamined Patent Publication No. 1997-20424 discloses the use of a release material by replacing polyethylene terephthalate or grasping paper by treating silicon with biaxially stretched polypropylene.
