It's about cardboard.
전자렌지 용품, 즉 마이크로파의 발열원리를 이용하여 각종 식품을 해동 또는 조리할 수 있는 팩키지(Package)로는, 전자파를 받은 도전성 금속막이 전자파에너지를 주울(Joule)열로서 열에너지화 하는 원리를 토대로 하여 내열성 있는 플라스틱 필름의 한 면에 알루미늄을 50∼70Å의 두께로 증착,사용하고 있다.As a package that can defrost or cook a variety of foods using a microwave heating principle, that is, the heat generation principle of microwaves, the conductive metal film which has received electromagnetic waves is heat-resistant based on the principle that the electromagnetic energy is thermal energy as Joule heat. Aluminum is deposited on one side of a plastic film in a thickness of 50 to 70 mm 3.
이러한 알루미늄 증착 필름(발열체)은 대부분의 마이크로파를 흡수, 투과하여 식품을 가열하며, 일반 포장용 필름 즉, 알루미늄이 350∼400Å의 두께로 진공증착된 필름과는 다르게 전자파의 반사 및 스파크 현상이 발생하지 않는다.The aluminum deposition film (heating element) absorbs and transmits most microwaves to heat food, and unlike general packaging films, that is, films in which aluminum is vacuum-deposited to a thickness of 350 to 400 Å, electromagnetic wave reflection and sparking do not occur. Do not.
실제로 상기 알루미늄 증착 필름은 그대로 사용되고 있지는 않으며, 대부분은 종이판지에 접착,사용하고 있다.In fact, the aluminum deposition film is not used as it is, and most of them are bonded and used on paperboard.

Attached ones were used.
이중에 알루미늄 호일 트레이는 전자렌지를 이용하여 식품을 조리하면 조리된 식품이 설익거나(Soggy) 와삭와삭(Crispy)한 느낌이 없는 등 제맛이 나지 않는다. 또 PET 필름에 광학적 밀도(Optical density) 0.22∼0.28 (광선투과율:Light trancmission rate 50∼60%)이 되도록 알루미늄 금속을 증착한 발열체가 전자파를 열에너지로 바꾸어 주기 때문에 식품이 건조(Drying) 및 브라우닝(Browning: 누런색으로 변하게 함)되고 와삭와삭한 식감을 갖으나, 발열체의 필름에 크랙이 발생하여 육안상 거부감을 느끼게 하는 단점을 갖고 있다.In the aluminum foil tray, when the food is cooked using a microwave oven, the cooked food does not taste like the cooked food is not soggy or crispy. In addition, the heating element with aluminum metal deposited on the PET film to have an optical density of 0.22 to 0.28 (Light trancmission rate of 50 to 60%) converts electromagnetic waves into thermal energy. Browning: It turns yellow and has a crisp texture, but it has a drawback that the cracks in the film of the heating element make it feel visually rejected.

도 1은 본 발명에 따른 전자렌지용 복합판지의 구조단면도이다.1 is a structural cross-sectional view of a composite cardboard for a microwave oven according to the present invention.
도면을 참조하면, 전자렌지용 복합판지(1)는 종이판지(10), 발열체(20) 및 접착제층(30)으로 구성되며, 상기 발열체(20)는 PET 필름(22)과 알루미늄 박막(24)으로 구성된다. 여기서 발열체는 광학적 밀도 0.22∼0.30에서의 빛투과율이 50∼60%가 되도록 조절해야 한다.Referring to the drawing, the composite cardboard 1 for a microwave oven is composed of a paper board 10, the heating element 20 and the adhesive layer 30, the heating element 20 is a PET film 22 and an aluminum thin film 24 It is composed of Here, the heating element should be adjusted so that the light transmittance at the optical density of 0.22 to 0.30 is 50 to 60%.
상기에서 베이스 필름으로 사용된 PET 필름(22)은 두께가 15㎛ 이하이면 식품의 해동 및 조리시 크랙이 발생하므로 15㎛ 이상, 특히 두께가 15∼30㎛인 것을 사용하는 것이 바람직하다. 또한 복합판지의 발열성능에 가장 영향을 끼치는 도전층 즉, 알루미늄 박막의 두께는 발열성능, 코스트, 생산성 면을 고려할 때 50∼70Å인 것이 좋다.When the PET film 22 used as the base film is 15 μm or less in thickness, cracks are generated during thawing and cooking of foods, so it is preferable to use 15 μm or more, especially 15 to 30 μm thick. In addition, the thickness of the conductive layer, that is, the aluminum thin film that most affects the heat generating performance of the composite board, is preferably 50 to 70 kPa in consideration of the heat generating performance, cost, and productivity.
또한 접착제로는 접착후 용제가 잔류되는 것이 방지하기 위해 수성접착제를 사용하는 것이 좋으며, 가장 바람직한 것은 수성 EVA계 접착제이다.In addition, it is preferable to use an aqueous adhesive as an adhesive to prevent the solvent from remaining after adhesion, and most preferably, an aqueous EVA adhesive.
종이판지(지지체: paperboard)는 기존에 사용되던 알루미늄 트레이나 트레이판지를 대신할 수 있는 포장강도를 갖는 것으로 현재 우유팩지로 사용하고 있는 평량 400∼600g/㎡의 순수 펄프를 사용하는 것이 좋다. 또한 포장상자를 만드는 종이판지를 사용하여도 무방하다.Paperboard (paperboard) has a packaging strength to replace the conventional aluminum tray or tray cardboard, it is recommended to use the pure pulp of the basis weight 400 ~ 600g / ㎡ currently used as milk cartons. It is also possible to use paperboard to make a box.
이와 같이 구성된 전자렌지용 복합판지(1)는 다음과 같은 순서에 의해 제조된다.The composite cardboard 1 for a microwave oven constructed in this way is manufactured by the following procedure.
1) 식품포장용 PET 필름(22) 원단의 한 면에 진공증착기를 사용하여 10-2∼10-6Torr의 압력하에서 알루미늄을 증착한다. 이때 도전층인 알루미늄 박막(24)의 두께를 50∼70Å로 조절한다.1) Aluminium is deposited on one surface of the PET film 22 for food packaging using a vacuum evaporator under a pressure of 10-2 to 10-6 Torr. At this time, the thickness of the aluminum thin film 24 which is a conductive layer is adjusted to 50-70 GPa.
2) 합지기를 사용하여 알루미늄 증착된 필름, 즉 발열체(20)의 알루미늄 박막 상에 수성 EVA계 접착제(30)를 5∼6g/㎡ 정도로 도포한 후 종이판지(10)와 라미네이팅하여 건조한다.2) After applying the aqueous EVA-based adhesive 30 to about 5 ~ 6g / ㎡ on the aluminum deposited film, that is, the aluminum thin film of the heating element 20 by using a laminating machine and dried by laminating with a paper cardboard (10).
3) 건조된 복합판지(1)를 식품의 트레이로 사용할 수 있도록 절단 가공한다. 이러한 복합판지는 전자렌지내에서 직접 발열트레이로 사용할 수 있다.3) Cut the dried composite cardboard (1) so that it can be used as a tray for food. Such composite cardboard can be used directly as a heating tray in a microwave oven.
이하, 실시예를 참조하여 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to Examples.
실시예Example
두께 25㎛의 이축연신 폴리에스터 필름의 한 면에 알루미늄을 편면 진공증착하였다. 이때 알루미늄 박막 필름(발열체)의 광선투과율은 52%이었으며(실제로 알루미늄 박막 두께를 측정하기 어려우며, 그 두께는 광선투과율의 조정에 의해 50∼70Å으로 조절할 수 있음), 발열체의 밀도는 아래의 식1로 계산하였더니 0.28 이었다.Aluminum was vacuum-deposited on one side of a biaxially stretched polyester film having a thickness of 25 μm. At this time, the light transmittance of the aluminum thin film (heating element) was 52% (in reality, it is difficult to measure the thickness of the aluminum thin film, and the thickness can be adjusted to 50 to 70 의해 by adjusting the light transmittance), and the density of the heating element is expressed by Equation 1 below. It was calculated as 0.28.
[식 1][Equation 1]
상기 식1에서 O.D는 광학적 밀도이고, T는 광선투과율이다.In Equation 1, O.D is optical density and T is light transmittance.
또한 25㎛ 두께의 필름에서 광선투과율에 따른 광학적 밀도를 계산하여 하기 표1에 나타냈다.In addition, the optical density according to the light transmittance in the film having a thickness of 25㎛ is shown in Table 1 below.
[표 1]TABLE 1
다음, 발열체의 알루미늄 박막 위에 수성 EVA계 접착제(삼원화학 제품, MO-40 그레이드)를 6g/㎡ 두께로 도포한 후 종이판지를 합지한다. 이때 공급되는 발열체와 종이판지는 합지기에서 롤 형태로 부착,합지하고, 오븐에서 건조시켰다.Next, an aqueous EVA-based adhesive (Samwon Chemical, MO-40 grade) is applied on the aluminum thin film of the heating element to a thickness of 6 g / m 2, and then paperboard is laminated. At this time, the heating element and paper cardboard supplied were attached and laminated in the form of a roll in a paper machine and dried in an oven.
상기 실시예에서 제조된 복합판지의 물성을 알아보기 위하여 시중 판매품인 냉동피자(해태제과의 나포리 피자)를 구입하여 복합판지 위에 크기에 맞춰 4등분하여 위치시킨 후 700W 전자렌지에서 시간과 강도를 변경시키면서 시험하였으며, 그 결과는 표2와 같다.In order to find out the properties of the composite cardboard manufactured in the above embodiment, a commercially available frozen pizza (Napori Pizza from Haitai Confectionery) was purchased and placed in quarters according to the size on the composite cardboard. The test was carried out while the results are shown in Table 2.
[표 2]TABLE 2
시험결과, 50Å∼70Å의 두께로 알루미늄을 증착한 폴리에스터 필름을 종이판지에 합지하여 만든 복합판지를 사용하였을 때 피자파이의 식감은 기존 알루미늄트레이와 비슷하였으나, 전자렌지에서 발생하는 전자파에 의해 가열된 복합판지의 표면 폴리에스터 필름에는 크랙 현상이 나타나지 않았고, 전자렌지내에서 전자파에 의한 발열상태가 현재 사용중인 알루미늄호일 트레이에 비해 우수하였다.As a result, the texture of pizza pie was similar to that of the existing aluminum tray when the composite paper made of a polyester film deposited with aluminum with a thickness of 50Å ~ 70Å was laminated on a paperboard, but it was heated by electromagnetic waves generated in a microwave oven. The cracked phenomenon did not appear on the surface polyester film of the composite cardboard, and the heating state due to electromagnetic waves in the microwave oven was superior to that of the aluminum foil tray currently in use.
또한 본 발명에 따른 복합판지를 전자렌지에 가열하기 전과 가열 후의 시료를 만들어 한국생활용품 시험연구원에 재질에 대한 인체유해성분의 용출시험을 의뢰한 결과 포장재로서 안정성에 이상이 없는 것으로 확인되었다.In addition, the composite cardboard according to the present invention was made before and after heating the sample in the microwave and asked the Korea Household Appliances Testing Institute for dissolution test of harmful substances on the material, it was confirmed that there is no abnormality in stability as a packaging material.
이상에서 상세히 설명한 바와 같이, 본 발명에 의한 전자렌지용 복합판지는 가열후 열화에 의한 필름 크랙이 발생하지 않아 포장재로서 육안상 거부감을 느끼지 않으며, 기존의 알루미늄 호일 트레이에 비해 짧은 시간에 냉동식품 등을 해동 및 조리할 수 있는 효과를 갖는다.As described in detail above, the microwave composite board according to the present invention does not generate a film crack due to deterioration after heating, and does not feel visual rejection as a packaging material, frozen food, etc. in a short time compared to the conventional aluminum foil tray It has the effect of thawing and cooking.
