Description
本發明係有關於一種紙容器之熔貼方法。 The present invention relates to a method of melting a paper container.
習知之紙製容器,接合處常利用原有用以防水之塑料淋膜層之熔融進行黏合,如專利TW M441372、TW M445398及TW M375054等所揭者。一般而言,欲黏合之部位須藉由高週波、超音波或熱風之方式以至少500℃之高溫進行熔壓貼合,才足以將淋膜層充分熔融而貼合,然而,500℃的高溫常造成假性黏著的問題,使接合處易發生滲漏,高溫更會造成紙張軟化變形,使接合處不平整、黏合不確實、甚至無法黏合的狀況,不僅影響良率,更易使接合處產生縫隙而造成滲漏,且自常溫直接緩緩加溫至500℃的過程使紙張變形與黏合不確實的狀況更加惡化,另外,加熱時間長,能源耗費大、生產效率不佳。 In conventional paper containers, the joints are often bonded by melting of the original plastic coating layer for waterproofing, such as those disclosed in patents TW M441372, TW M445398 and TW M375054. In general, the part to be bonded must be melt-bonded at a high temperature of at least 500 ° C by means of high frequency, ultrasonic or hot air, so that the coating layer is sufficiently melted and adhered. However, the high temperature of 500 ° C Often causing the problem of pseudo-adhesive, the joint is prone to leakage, the high temperature will cause the paper to soften and deform, the joint is not flat, the adhesive is not sure, or even can not be bonded, which not only affects the yield, but also makes the joint more likely to occur. Leakage caused by the gap, and the process of directly heating to 500 ° C from the normal temperature makes the deformation and adhesion of the paper worse, and the heating time is long, the energy consumption is large, and the production efficiency is not good.
另一方面,當塑料淋膜層為PP(聚丙烯)或PET(聚對苯二甲酸乙二酯)材質時,在500℃高溫之下會造成塑料淋膜層的熱分解,進而造成塑料淋膜層失去黏性,根本無法黏合。 On the other hand, when the plastic coating layer is made of PP (polypropylene) or PET (polyethylene terephthalate), the thermal decomposition of the plastic coating layer is caused at a high temperature of 500 ° C, which causes the plastic to drip. The film loses its viscosity and cannot bond at all.
因此,如何進行熔貼以避免紙張變形,又可使塑料淋膜層充分熔融黏合,不致產生假性黏著現象,並降低加熱之成本,成為業界亟待解決之課題。 Therefore, how to carry out the fusion to avoid deformation of the paper, and the plastic coating layer can be fully melted and bonded, does not cause false adhesion, and reduces the cost of heating, which has become an urgent problem to be solved in the industry.
本發明之主要目的在於提供一種紙容器之熔貼方法,能避免紙張因高溫變形,並能減少因假性黏著而滲漏的機會。 The main object of the present invention is to provide a method for melting a paper container, which can prevent the paper from being deformed by high temperature and can reduce the chance of leakage due to false adhesion.
為達成上述目的,本發明提供一種紙容器之熔貼方法,包含以下步驟: In order to achieve the above object, the present invention provides a method for melting a paper container, comprising the steps of:
一、製備一原紙材,該原紙材包含一第一部位與一第二部位,其中至少該第一部位表面具有一塑料淋膜層。 1. Preparing a raw paper material, the raw paper material comprising a first portion and a second portion, wherein at least the surface of the first portion has a plastic coating layer.
二、對該第一部位以介於80℃至200℃之間的溫度進行預熱。 2. Preheating the first portion at a temperature between 80 ° C and 200 ° C.
三、將該第二部位貼合於該第一部位上並以260℃至400℃之間的溫度進行熔貼壓合,使該塑料淋膜層熔化而將該第一部位與該第二部位彼此緊密黏合。 3. bonding the second portion to the first portion and performing a fusion bonding at a temperature between 260 ° C and 400 ° C to melt the plastic coating layer to bond the first portion and the second portion Close to each other.
四、將熔貼壓合完畢之原紙材製成一紙容器。 4. The original paper material that has been pressed and laminated is made into a paper container.
藉由對塑料淋膜層進行預熱,第二部位便能以較低的溫度熔貼至第一部位,不僅不會造成紙張因高溫而變形,更可縮減加熱時間,節省加熱之成本,更重要的是,可避免高溫熔貼使塑料淋膜層分解造成假性黏著,以確保第一部位與第二部位間確實結合而不致滲漏。 By preheating the plastic coating layer, the second part can be fused to the first part at a lower temperature, which not only does not cause the paper to be deformed due to high temperature, but also reduces the heating time, saves the cost of heating, and more It is important to avoid the high temperature melting of the plastic coating layer to cause pseudo-adhesion to ensure that the first part and the second part are indeed combined without leakage.

Preparing a raw paper material, the raw paper material comprising a first portion and a second portion, wherein at least the surface of the first portion has a plastic coating layer, and the material of the plastic coating layer is selected from PP (polypropylene) a group consisting of PE (polyethylene), PS (polystyrene), and PET (polyethylene terephthalate); for example, as shown in FIG. 2 and FIG. 2A, the base paper 10 is Cutting into a shape of a paper cup, at least one of the original paper material 10 has the plastic coating layer 111, and the first portion 11 and the second portion 12 are respectively located on the original paper material 10 side. 3 to 5 disclose a raw paper 10' for making a compartment, the original paper 10' comprising a previously separated partition and a base, the base having the first portion 11', the partition The bottom portion has the second portion 12'. Therefore, the first portion and the second portion are not limited to being located on the same paper object, and the first portion and the second portion are not located on two different paper objects.
二、第一部位以80℃~200℃預熱S1:對該第一部位以介於80℃至200℃之間的溫度進行預熱,使第一部位的表面溫度約為70℃~200℃,較佳者,係以非接觸式加熱方式對該第一部位進行預熱。 Second, the first part is preheated at 80 ° C ~ 200 ° C S1: the first part is preheated at a temperature between 80 ° C and 200 ° C, so that the surface temperature of the first part is about 70 ° C ~ 200 ° C Preferably, the first portion is preheated by non-contact heating.
三、第二部位以260℃~400℃熔貼壓合至第一部位S2:將該第二部位貼合於該第一部位上並以260℃至400℃之間的溫度進行熔貼壓合,使該塑料淋膜層熔化而將該第一部位與該第二部位彼此緊密黏合。舉例來說,如圖2及圖2A所示,該第一部位11與該第二部位12藉由熔融之塑料淋膜層111彼此緊密黏合,而可進一步供製造成紙容器成品;於圖3至圖5中,該第一部位11'亦與該第二部位12'藉該塑料淋膜層111'彼此黏合,而能進一步供製成紙容器成品。於本發明之主要實施例中,係以接觸式加熱的方式將該第二部位貼壓於該第一部位上,較佳者,係利用高週波或超音波之加熱方式予以加熱熔貼。 3. The second portion is press-bonded to the first portion S2 at 260 ° C to 400 ° C: the second portion is attached to the first portion and is melt-bonded at a temperature between 260 ° C and 400 ° C. The plastic coating layer is melted to tightly bond the first portion and the second portion to each other. For example, as shown in FIG. 2 and FIG. 2A, the first portion 11 and the second portion 12 are closely adhered to each other by the molten plastic coating layer 111, and can be further processed into a finished paper container; As shown in FIG. 5, the first portion 11' is also bonded to the second portion 12' by the plastic coating layer 111', and can be further prepared into a finished paper container. In a main embodiment of the present invention, the second portion is pressed against the first portion by contact heating, preferably by heating with a high frequency or ultrasonic wave.
四、製成紙容器S3:將熔貼壓合完畢之原紙材製成一紙容器,如圖2中的杯具紙容器20與圖3至圖4中之餐盒紙容器20'。 4. Forming the paper container S3: The raw paper material after the fusion bonding is completed into a paper container, such as the cup paper container 20 in FIG. 2 and the lunch box paper container 20' in FIGS. 3 to 4.
藉由上述方法,可避免紙張受到高溫影響而變形、避免假性黏著、防止塑料淋膜層因高溫而熱分解進而失去黏性、並能減少加熱時間與成本,所製成之紙容器外觀平整、良率較高,且接合處黏合穩固不易脫離、亦不易因紙張變形造成縫隙而引起滲漏之現象,極具進步之效。 By the above method, the paper can be prevented from being deformed by the influence of high temperature, avoiding false adhesion, preventing the plastic coating layer from being thermally decomposed due to high temperature and losing viscosity, and reducing heating time and cost, and the appearance of the paper container is smooth. The yield is high, and the bonding at the joint is stable and not easy to be separated, and it is not easy to cause leakage due to the gap caused by the deformation of the paper, which is highly effective.
