일반적으로 우편물은 종이에 담아 발송하게 되며 발신인과 수신인을 기재하여야 한다.In general, postal mail is sent on paper, and the sender and recipient must be indicated.

이를 직접 펜으로 써서 기재하거나 또는 주소가 인쇄된 라벨을 부착시키는 방식이 사용된다.A method of directly writing it with a pen or attaching a label with an address printed thereon is used.

근래에는 종이 우편의 물량이 날로 증가하고 있으며, 속지에 발신자의 주소와 수신자의 주소를 기입하여 이를 봉투에 삽입하였을 때, 상기 주소부가 봉투의 외부에서 인식이 될 수 있어 별도로 봉투에 발신자와 수신자의 주소를 기입하지 않아도 되는 투명창 봉투의 사용이 증가하고 있다.In recent years, the volume of paper mail is increasing day by day, and when the sender's address and the recipient's address are written on the inside sheet and inserted into an envelope, the address can be recognized from the outside of the envelope, so the sender and recipient's address is separately placed in the envelope. The use of transparent window envelopes, which do not require addressing, is increasing.

종래에는 종이에 투명창 부착부에 해당하는 개구공을 형성하고, 비닐시트를 개구공에 각기 부착시켜 완성되었다.Conventionally, it was completed by forming openings corresponding to transparent window attachments on paper and attaching vinyl sheets to the openings, respectively.

그러나 종래 투명창이 부착된 종이는 비닐을 제거한 후 분리수거 해야 하나 과정이 번거로워서 제대로 분리수거가 이루어지지 못하는 단점이 있었다.However, the conventional transparent window-attached paper had to be collected separately after removing the vinyl, but the process was cumbersome, so there was a disadvantage in that the separate collection could not be properly performed.

A perspective view showing a curing process in manufacturing a paper bag according to the first and second embodiments of the present invention, and FIG. 4 is a developed view showing a paper bag manufactured according to the present invention.

도 1에 도시된 바와 같이, 본 발명 제1실시예에 따른 종이봉투의 제조방법은,As shown in FIG. 1, the method for manufacturing a paper bag according to the first embodiment of the present invention,

1단계(S1) : 투명창 원액은, 원재료와 부재료를 7:3 또는 8:2의 혼합비율로 혼합한다.Step 1 (S1): For the transparent window stock solution, mix raw materials and sub-materials in a mixing ratio of 7:3 or 8:2.

원재료는, 건성유 또는 반건성유 중 택일되거나 이들의 혼합물로 이루어진다.The raw material is selected from drying oil or semi-drying oil or a mixture thereof.

건성유는 미네랄 오일, 베이비 오일, 파라핀 오일, 실리콘 오일, 크리스탈 오일, 아마인기름, 오동나무기름, 들기름 중 택일되거나 2 이상을 혼합한 것이다.Drying oil is selected from mineral oil, baby oil, paraffin oil, silicone oil, crystal oil, linseed oil, paulownia oil, and perilla oil, or a mixture of two or more.

일 예에 따르면 아마인기름 100중량부를 기준하여 오동나무기름 20~30중량부, 들기름 5~10 중량부를 혼합한다.According to one example, based on 100 parts by weight of linseed oil, 20 to 30 parts by weight of paulownia oil and 5 to 10 parts by weight of perilla oil are mixed.

반건성유는, 유채기름, 콩기름, 옥수수기름 중 택일되거나 2 이상을 혼합한 것이다.Semi-drying oil is selected from among rapeseed oil, soybean oil, and corn oil, or a mixture of two or more.

일 예에 따르면 유채기름 100중량부를 기준하여 콩기름 10~20중량부, 옥수수기름 20~30 중량부를 혼합한다.According to one example, 10 to 20 parts by weight of soybean oil and 20 to 30 parts by weight of corn oil are mixed based on 100 parts by weight of rapeseed oil.

부재료는 이소프로필 알콜, 코발트 시카티프(cobalt siccatif), 수성왁스로 이루어진 군에서 선택되는 어느 하나 또는 2 이상의 혼합물로 이루어진다.The auxiliary material is made of any one or a mixture of two or more selected from the group consisting of isopropyl alcohol, cobalt siccatif, and water-based wax.

유채기름이나 콩기름은 반건성유라 건조가 늦고, 건성유는 건조가 빨리 이루어질 수 있고, 더욱이 건성유의 건조를 보다 빨리 이루어지기 위해서 첨가제가 사용될 수 있는데, 코발트 시카티프(cobalt siccatif)를 소량 첨가한다.Rapeseed oil or soybean oil is a semi-drying oil, so drying is slow, drying oil can dry quickly, and moreover, additives can be used to make drying oil dry faster, and a small amount of cobalt siccatif is added.

예를들어 원재료 100중량부 기준으로 부재료는 2~4중량부를 첨가한다.For example, based on 100 parts by weight of raw materials, 2 to 4 parts by weight of auxiliary materials are added.

2단계(S2) : 이렇게 제조된 투명창 원액을 종이봉투(2)의 특정부위(20)에 도포한다.Step 2 (S2): The transparent window stock solution thus prepared is applied to a specific area 20 of the paper bag 2.

투명창 원액은 약 0.3~1 mm의 두께로 도포함이 바람직하나 반드시 이에 한정될 필요는 없다.The transparent window stock solution is preferably applied to a thickness of about 0.3 to 1 mm, but it is not necessarily limited thereto.

투명도는 모조지의 두께에 비례하며 얇을수록 투명도는 올라간다.Transparency is proportional to the thickness of imitation paper, and the thinner it is, the higher the transparency.

종이봉투(2)의 두께는 모조지 80~100g을 많이 사용하나 투명도를 위해서 그 이하의 두께를 사용하는 것도 좋다.For the thickness of the paper bag 2, 80 to 100 g of imitation paper is used a lot, but it is good to use a thickness less than that for transparency.

3단계(S3) : 이후 투명창 원액이 도포된 종이봉투(2)를 건조시킨다.Step 3 (S3): Then, the paper bag 2 coated with the transparent window stock solution is dried.

바람직하게는 자연건조에 의하거나 또는 열을 갖는 로울러(R)에 통과시켜 건조시킨다.Preferably, it is dried by natural drying or by passing through a roller (R) having heat.

상기한 종이봉투(2)는 모조지가 적당하다.For the paper bag 2 described above, imitation paper is suitable.

모조지의 굴절지수는 모조지를 구성하는 원료에 의하여 결정된다.The refractive index of imitation paper is determined by the raw material constituting the imitation paper.

모조지를 구성하는 여러가지 원료중 가장 많은 부분을 차지하는 것이 펄프와 탄산칼슘이고, 굴절지수는 각각 1.5-1.6 사이에 분포한다.Pulp and calcium carbonate account for the largest portion among various raw materials constituting imitation paper, and the refractive index is distributed between 1.5-1.6, respectively.

빛이 종이에 비추어지면 종이를 구성하는 원료를 통과할 때마다 경계면에서 굴절이 일어나는데, 굴절지수의 차이가 클수록 빛의 산란이 많이 일어나 사람의 눈에는 불투명하게 보인다,When light shines on paper, refraction occurs at the interface whenever it passes through the raw materials constituting the paper.

모조지의 경우 펄프와 펄프, 펄프와 탄산칼슘 사이가 공기로 채워져 있는데, 공기의 굴절률이 약 1.0003으로 펄프 및 탄산칼슘과의 굴절지수 차이가 크기 때문에 빛의 굴절과 산란이 많이 일어나기 때문에 종이는 불투명한 성질을 나타낸다.In the case of imitation paper, air is filled between pulp and pulp and between pulp and calcium carbonate. The refractive index of air is about 1.0003, and the difference between the refractive index of pulp and calcium carbonate is large, so light refraction and scattering occur a lot, so paper is opaque. characterizes.

이 공기 부분을 굴절률 차이가 크지 않은 상기 투명창 원액으로 치환시켜줌으로써 빛의 굴절이 적게 일어나 투명성이 개선될 수 있는 것이다.By substituting this air portion with the transparent window stock solution having a small refractive index difference, less refraction of light occurs and transparency can be improved.

만약 종이에 굴절률이 1.33인 물로 적시기만 해도 마른 종이에 비하여 다소 투명해지는 것은 종이 내부에 있는 공기를 물로 대체하여 종이내 주원료인 펄프와의 굴절률 차이를 줄여주었기 때문이다.If the paper is wetted with water with a refractive index of 1.33, it becomes somewhat more transparent than the dry paper because the air inside the paper is replaced with water to reduce the difference in refractive index with the pulp, which is the main material in the paper.

기름이 건조된다는 것은 중합에 의하여 분자량이 커진다는 것을 의미하며, 결국 리싸이클은 어려울 것이다.Drying the oil means that the molecular weight is increased by polymerization, so recycling will be difficult.

실제로 기름 먹였던 종이들이 리싸이클시 잘 해리가되지 않아 별도로 폐기처분된다. 단지 소각하거나 매립할 경우 플래스틱보다는 오염물질 배출이 적게 된다는 장점이 있다.In fact, papers that have been oiled are disposed of separately because they do not dissociate well during recycling. It has the advantage of lower pollutant emissions than plastic when simply incinerated or landfilled.

한편 투명창(3)이 형성된 특정부위(20)의 주변에 절취선(23)이 형성되어 투명창(3)만 뜯어내어 제거한 후 종이로 분리수거할 수 있다(S4).On the other hand, a perforation line 23 is formed around the specific portion 20 where the transparent window 3 is formed, so that only the transparent window 3 can be torn off and removed, and then collected separately as paper (S4).

절취선(23)은 다수의 점선형태의 슬릿이 직선방향으로 형성되어 이루어지며, 한줄 또는 여러줄이 병렬 배치되거나 지그재그 형태로 점선슬릿이 형성되어 이루어진다.The perforation line 23 is formed by forming a plurality of slits in the form of dotted lines in a straight direction, and one line or several lines are arranged in parallel or dotted line slits are formed in a zigzag shape.

이렇게 여러줄의 절취선(23)을 형성함으로써 쉽게 파손되지 않게 된다.By forming several lines of perforations 23 in this way, it is not easily damaged.

상술한 실시예에 따른 종이봉투의 제조방법에 의해 제조되는 부분적 투명창이 형성된 종이봉투는, 종이봉투(2)에 투명창 원액이 도포 후 건조되어 투명창(3)이 형성되고, 상기 투명창 원액은 건성유 또는 반건성유 중 택일되거나 이들의 혼합물로 이루어지는 원재료와, 이소프로필 알콜, 코발트 시카티프, 수성왁스로 이루어진 군에서 선택되는 어느 하나 또는 2 이상의 혼합물로 이루어진 부재료를 혼합하여 이루어진다..In the paper bag having a partially transparent window manufactured by the method for manufacturing a paper bag according to the above-described embodiment, the transparent window undiluted solution is applied to the paper bag 2 and then dried to form a transparent window 3, and the transparent window undiluted solution It is made by mixing a raw material selected from drying oil or semi-drying oil or a mixture thereof, and an auxiliary material selected from the group consisting of isopropyl alcohol, cobalt cicatif, and water-based wax, or a mixture of two or more.

건성유는 미네랄 오일, 베이비 오일, 파라핀 오일, 실리콘 오일, 크리스탈 오일, 아마인기름, 오동나무기름, 들기름 중 택일되거나 2 이상을 혼합한 것이다.Drying oil is selected from mineral oil, baby oil, paraffin oil, silicone oil, crystal oil, linseed oil, paulownia oil, and perilla oil, or a mixture of two or more.

반건성유는 유채기름, 콩기름, 옥수수기름 중 택일되거나 2 이상을 혼합한 것이다.Semi-drying oil is selected from among rapeseed oil, soybean oil, and corn oil, or a mixture of two or more.

부분적 투명창이 형성된 종이봉투는 투명창(3)의 주변에 절취선(23)이 형성되고, 절취선(23)은 다수의 점선형태의 슬릿이 직선방향으로 형성되어 이루어지며, 한줄 또는 여러줄이 병렬 배치되거나 지그재그 형태로 점선슬릿이 형성되어 이루어진다.A paper bag with a partially transparent window has a perforated line 23 formed around the transparent window 3, and the perforated line 23 is formed by forming a plurality of slits in the form of dotted lines in a straight direction, and one or several lines are arranged in parallel. or a dotted line slit is formed in a zigzag form.

한편 도 2에 도시된 바와 같이, 본 발명 제2실시예에 따른 종이봉투의 제조방법은,On the other hand, as shown in Figure 2, the manufacturing method of the paper envelope according to the second embodiment of the present invention,

1공정(P1): 다색 인쇄부에서 종이봉투(2)에 다색의 문양이나 문자를 인쇄한다.Step 1 (P1): Multi-color patterns or characters are printed on the paper bag 2 in the multi-color printing unit.

다색 인쇄부는 1도 내지 6도 인쇄까지 가능하도록 6개의 인쇄부로 이루어지고, 필요에 따라 2도 부터 6도 인쇄부까지 선택적으로 적용될 수 있다.The multi-color printing unit consists of six printing units to enable 1 to 6 color printing, and can be selectively applied from 2 to 6 color printing units as needed.

종이봉투(2)의 투명창(3)이 형성되어야 할 특정부위(20)의 주변에 굵은 선으로 테두리(25)를 인쇄한다.An edge 25 is printed with a thick line around a specific portion 20 where the transparent window 3 of the paper bag 2 is to be formed.

2공정(P2): 이후 다색 인쇄부를 통과하여 다색 인쇄된 종이봉투(2)의 특정부위(20)에 파라핀 또는 액상 하바리움을 도포한다.Step 2 (P2): After passing through the multi-color printing unit, paraffin or liquid herbarium is applied to a specific area 20 of the multi-color printed paper bag 2.

파라핀은 20 혹은 40의 탄소분자로 이루어진 탄화수소분자의 혼합물로 석유나 석탄, 오일셰일에서 도출된 하얗고 색깔 없는 부드러운 고체이다.Paraffin is a mixture of hydrocarbon molecules composed of 20 or 40 carbon molecules and is a white, colorless, soft solid derived from petroleum, coal, or oil shale.

액상 하바리움은 파라핀 왁스에 유화제를 혼합하여 액상화한 것이다.Liquid herbarium is liquefied by mixing paraffin wax with an emulsifier.

파라핀원료는 고체이므로 인쇄하기 용이한 액상점도를 갖도록 적정한 점도로 제조되어야 한다.Since the paraffin raw material is a solid, it must be prepared with an appropriate viscosity to have a liquidus viscosity that is easy to print.

종이(모조지)를 투명하게 만들때 가장 중요한 것은 종이의 기본 굴절률에 가장 가까운 소재를 사용해야 하는데 하바리움의 점도가 적정한 점도가 되도록 제조되어야 한다. 하바리움은 굴절률이 종이에 가장 근접하는 근사체이다.When making paper (imitation paper) transparent, the most important thing is to use a material closest to the basic refractive index of paper, and it must be manufactured so that the viscosity of herbarium becomes an appropriate viscosity. Herbarium is the closest approximation in refractive index to paper.

종이는 원소재이고, 하바리움은 부소재이면서 굴절률이 가장 좋다.Paper is a raw material, and Herbarium is an auxiliary material and has the best refractive index.

하바리움은 인쇄할때 빨리 건조해야 하므로 점성도를 최적의 상태로 만드는 것이 중요하다.Herbarium needs to dry quickly when printing, so it is important to optimize the viscosity.

시중에 판매되고 있는 하바리움 액상은 물처럼 흐르는 수준이라 사용 할수가 없어서 경화제를 사용하여 최적의 점도를 갖도록 하였다.Commercially available herbarium liquids flow like water, so they cannot be used, so a hardener is used to have the optimum viscosity.

바람직한 점도는 라드(돼지기름)과 비슷한 60~70 CP이거나 또는 꿀, 마요네즈와 비슷한 2000~3000CP일 수 있다. 이는 하나의 예시일뿐이며 반드시 이에 한정될 필요는 없을 것이다.The preferred viscosity may be 60-70 CP similar to lard (pork fat) or 2000-3000 CP similar to honey and mayonnaise. This is just one example and will not necessarily be limited thereto.

3공정(P3): 이후 파라핀 또는 액상 하바리움이 도포된 종이봉투(2)를 약 120~130℃로 가열된 로울러 사이에 통과시킨다.Step 3 (P3): Then, the paper bag 2 coated with paraffin or liquid herbarium is passed between rollers heated to about 120 to 130 ° C.

이후 가열에 의해 경화되고 파라핀 또는 액상 하바리움이 경화되면서 투명창(3)이 형성될 수 있다.After curing by heating, the transparent window 3 may be formed as paraffin or liquid herbarium is cured.

한편 투명창(3)이 형성된 특정부위(20)의 주변에 절취선(23)이 형성되어 투명창(3)만 뜯어내어 제거한 후 폐종이로 분리수거할 수 있다(P4).On the other hand, a perforation line 23 is formed around the specific part 20 where the transparent window 3 is formed, so that only the transparent window 3 can be torn off and removed, and then collected separately as waste paper (P4).

절취선(23)은 다수의 슬릿이 직선방향으로 형성되어 이루어지며, 한줄 또는 여러줄이 병렬 배치되어 이루어진다.The perforation line 23 is formed by forming a plurality of slits in a straight direction, and one line or several lines are arranged in parallel.

여러줄의 절취선(23)을 형성함으로써 쉽게 파손되지 않도록 한다.By forming several rows of perforated lines 23, it is prevented from being easily damaged.

상술한 다른 실시예에 따른 부분적 투명창이 형성된 종이봉투의 제조방법에 의해 제조된 부분적 투명창이 형성된 종이봉투는, 종이봉투(2)에 특정부위에 파라핀 또는 액상 하바리움이 도포 후 가열 건조되어 투명창(3)이 형성되어 이루어진다.In the paper bag having a partially transparent window manufactured by the method for manufacturing a paper bag having a partially transparent window according to the above-described other embodiment, paraffin or liquid herbarium is applied to a specific portion of the paper bag 2 and then heated and dried to open the transparent window. (3) is formed.

또한 투명창(3)의 주변에 절취선(23)이 형성되고, 절취선(23)은 다수의 점선형태의 슬릿이 직선방향으로 형성되어 이루어지며, 한줄 또는 여러줄이 병렬 배치되거나 지그재그 형태로 점선슬릿이 형성되어 이루어진다.In addition, a perforation line 23 is formed around the transparent window 3, and the perforation line 23 is formed by forming a plurality of slits in the form of a dotted line in a straight direction, and one line or several lines are arranged in parallel or dotted line slits in a zigzag form. this is formed

비록 바람직한 실시예와 관련하여 설명되어졌지만, 발명의 요지와 범위로부터 벗어남이 없이 다양한 수정 및 변형이 가능한 것은 당업자라면 용이하게 인식할 수 있을 것이며, 이러한 변경 및 수정은 모두 첨부된 청구의 범위에 속함은 자명하다.Although described in relation to preferred embodiments, it will be readily recognized by those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, and all such changes and modifications fall within the scope of the appended claims. is self-explanatory.
