Description

包含石墨烯的蒸煮食品包装用膜
技术领域
本申请涉及包含石墨烯的蒸煮食品包装用膜及上述蒸煮食品包装用膜的制造方法。
背景技术
将未延伸的聚丙烯(polypropylene；以下称为PP)称为流延聚丙烯膜(castingpolypropylene film；CPP film)，即其无延伸膜被称为流延聚丙烯膜。上述流延聚丙烯膜具有优秀的透明性、表面光泽，并且具有优秀的热粘结强度、尺寸稳定性，因而主要用作食品包装材料或药剂包装材料。
食品包装材料需具备可抵抗外部冲击的适当的强度，需对水分、温度、氧或光线等的影响化学或微生物变化的原因具备适当的阻隔性。由于无法仅通过使用聚丙烯膜或流延聚丙烯膜来全部满足所需的上述物性，为了对其进行加强，主要使用含有铝箔或铝蒸镀层的包装材料。但是，当前市面上的含有铝的包装材料存在如下的问题，即，因芯层过厚而导致整个包装材料变厚，铝的使用量很大。

根据本申请实例的包括芯层的蒸煮食品包装用膜通过使密封剂层、第一粘结剂层、第二粘结剂层以及表面层中的一个以上的层包含石墨烯来达到即使上述芯层的厚度薄也能够用作蒸煮食品包装材料的效果。具体地，在将上述蒸煮食品包装用膜用于食品包装材料的情况下，以使耐燃性及耐冲击性得到增加的方式使机械强度增加，使水分、氧等的阻隔性增加，以及使耐化学性增加，有可减少铝使用量的优点。并且，即使在仅使上述密封剂层、上述第一粘结剂层、上述第二粘结剂层以及上述表面层中的一个包含石墨烯的情况下也可起到以上所要实现的效果，即使两个层包含石墨烯或所有层包含石墨烯，也可起到以上所要实现的效果。

以下，参照附图详细说明本申请的实例及实施例。但是，本申请并不限定于这种实例、实施例以及附图。
本申请的第一实施方式提供一种蒸煮食品包装用膜，包括：密封剂层；第一粘结剂层，形成于上述密封剂层上；芯层，形成于上述第一粘结剂层上；第二粘结剂层，形成于上述芯层上；以及表面层，形成于上述第二粘结剂层上，其中，上述密封剂层、上述第一粘结剂层、上述第二粘结剂层以及上述表面层中的一个以上的层包含石墨烯。
具体地，在本申请一实例的蒸煮食品包装用膜中，通过使上述密封剂层、上述第一粘结剂层、上述第二粘结剂层以及上述表面层中的一个以上的层包含石墨烯来达到即使上述芯层的厚度薄也能够用作蒸煮食品包装材料的效果。更具体地，在将上述蒸煮食品包装用膜用于食品包装材料的情况下，以使耐燃性及耐冲击性得到增加的方式使机械强度增加，使水分、氧等的阻隔性增加，以及使耐化学性增加，有可减少铝使用量的优点。
根据本申请的一实例，上述芯层的厚度可达到约5μm至约60μm。具体地，上述芯层的厚度可达到约5μm至约60μm、约12μm至约60μm、约12μm至约55μm、约12μm至约50μm、约12μm至约45μm、约12μm至约40μm、约12μm至约35μm、约12μm至约30μm、约15μm至约60μm、约20μm至约60μm、约25μm至约60μm、约30μm至约60μm、约20μm至约50μm、约25μm至约50μm、约30μm至约50μm、约35μm至约45μm或约40μm至约45μm，但并不限定于此。现有技术的蒸煮食品包装用膜使芯层的厚度至少达到50μm，只有这样才能够具有用作食品包装材料的耐久性，但本申请一实例的蒸煮食品包装用膜即使使芯层的厚度达到小于50μm也具有可用作食品包装材料的耐久性的效果，即使最大达到5μm也具有可用作食品包装材料的耐久性的效果。
根据本申请的一实例，上述密封剂层的厚度可达到约30μm至约100μm。具体地，上述密封剂层的厚度可达到约30μm至约100μm、约40μm至约100μm、约40μm至约90μm、约40μm至约80μm、约40μm至约70μm、约40μm至约60μm、约50μm至约100μm、约60μm至约100μm、约70μm至约100μm、约80μm至约100μm、约50μm至约90μm、约50μm至约80μm或约60μm至约80μm，但并不限定于此。
根据本申请的一实例，上述第一粘结剂层或上述第二粘结剂层的厚度可达到约1μm至约10μm。具体地，上述第一粘结剂层或上述第二粘结剂层可达到约1μm至约10μm、约1μm至约8μm、约1μm至约6μm、约1μm至约4μm、约3μm至约10μm、约5μm至约10μm、约7μm至约10μm、约3μm至约7μm、约4μm至约6μm或约1μm至约3μm，但并不限定于此。
根据本申请的一实例，上述表面层的厚度可达到约10μm至约30μm。具体地，上述表面层的厚度可达到约10μm至约30μm、约15μm至约30μm、约20μm至约30μm、约25μm至约30μm、约15μm至约25μm、约15μm至约20μm或约20μm至约25μm，但并不限定于此。
参照图1，本申请一实例的蒸煮食品包装用膜可包括厚度达到约40μm至约100μm的上述密封剂层10、厚度达到约12μm至约60μm的上述芯层20、厚度达到约1μm至约10μm的上述第一粘结剂层401或上述第二粘结剂层402、厚度达到约15μm至约30μm的上述表面层30。现有技术即使在形成厚度达到40μm的芯层的情况下，也出现了龟裂或破裂的问题，相反，本申请的一实例具有如下的优点，即使上述芯层形成12μm的最小厚度，也可实现没有任何问题的食品包装材料。并且，在一实施例中，在将共挤出流延聚丙烯膜用作上述密封剂层的情况下，可使上述密封剂层的厚度达到40μm至100μm，在将流延聚丙烯膜用作上述密封剂层的情况下，可使上述密封剂层的厚度达到60μm至100μm。
在图1中，由密封剂层10、芯层20、表面层30以及粘结剂层40构成蒸煮食品包装用膜，上述粘结剂层40包括第一粘结剂层401以及第二粘结剂层402，但这仅属于例示，追加包括可用于蒸煮食品包装材料的膜或减少可用于蒸煮食品包装材料的膜的情况只要不脱离本申请的技术思想的范围，也包括在本申请的一实例。作为一例，上述蒸煮食品包装用膜还能够以追加包括可用于食品包装材料的膜的方式形成5层、7层、9层或11层的结构，还能够以减少可用于食品包装材料的膜的方式形成2层结构。
根据本申请的一实例，上述石墨烯可增加上述蒸煮食品包装用膜的整体耐久性，减少透气性及透湿性。

根据本申请的一实例，上述石墨烯可选自由石墨烯、氧化石墨烯(GO)、还原氧化石墨烯(rGO)、石墨烯纳米微片及它们的组合组成的组。具体地，上述氧化石墨烯包含多个氧化石墨烯片，上述还原氧化石墨烯可包含多个还原氧化石墨烯片，上述多个石墨烯片及上述多个还原氧化石墨烯片分别包括含氧官能团和/或针孔。例如，上述还原氧化石墨烯可通过如下的方式制备，即，通过使石墨(graphite)过氧化来获取氧化石墨烯，通过使所获取的上述氧化石墨烯来获取还原氧化石墨烯，但并不限定于此。在使上述石墨过氧化的过程中，在石墨烯的边缘及石墨烯内部生成含氧官能团，通过产生缺陷来生成针孔，从而使最终获取的上述还原氧化石墨烯片分别包含含氧官能团和/或针孔。
根据本申请的一实例，上述含氧官能团可包含选自由羟基(hydroxyl group)、环氧基(epoxy group)、羧基(carboxyl group)、酮基(ketone group)以及它们的组合组成的组，但并不限定于此。

根据本申请的一实例，上述密封剂层可包含聚丙烯(PP)、流延聚丙烯(castingpolypropylene，CPP)或共挤出流延聚丙烯(Coextruded Cast Polypropylene，CPR)。具体地，上述密封剂层为对蒸煮食品用包装材料赋予热封性的部分，可使多个上述密封剂层相向并对边角部分进行热封来制造成蒸煮食品用包装材料。为了体现具有高机械强度的膜，可使用聚丙烯、流延聚丙烯或共挤出流延聚丙烯。尤其，共挤出流延聚丙烯柔韧性优秀、粘结能力出色，拉伸强度、延伸率、扯裂强度等方面与玻璃纸相似或气体透过性更低，从而适合用作蒸煮食品包装用成分。并且，上述流延聚丙烯无色、无味、无毒性，因而卫生，由于比重在塑料中最低而具有价格便宜的优点，由于耐气体透过性良好，因而适合用作蒸煮食品包装用成分。
根据本申请的一实例，上述芯层可包含铝箔或铝蒸镀层，但并不限定于此。
根据本申请的一实例，上述第一粘结剂层及第二粘结剂层可包含聚氨酯类粘结剂、丙烯酸类粘结剂、环氧类粘结剂、聚烯烃类粘结剂、弹性体类粘结剂或氟类粘结剂，但并不限定于此。

以下，参照实施例来更详细地说明本申请，但本申请并不限定于此。
[实施例]
1.实施例
1-1.形成密封剂层及表面层
准备聚丙烯和尼龙树脂来在240℃的温度下使其熔融，以800kg/h的挤出量进行挤出并向T型模头供给。之后，以不延伸的方式对聚丙烯熔融物进行加工，从而形成平均厚度达到40μm至50μm的密封剂层，以不延伸的方式对尼龙树脂熔融物进行加工，从而形成平均厚度达到15μm至30μm的密封剂层。
1-2.形成芯层
准备铝原料(带)并在再结晶温度下使其经过旋转的2个辊之间来以板形态加工铝，从而形成平均厚度达到35μm至40μm的芯层。
1-3.形成蒸煮食品包装用膜
将密封剂层、芯层、表面层按顺序配置在层压用辊，通过驱动辊来引出并形成以上述密封剂层、上述芯层及上述表面层的顺序层压的平均厚度达到90μm至185μm的蒸煮食品包装材料。在上述层压中使用的粘结剂为丙烯酸类粘结剂，使用了相对于100重量份的总粘结剂包含0.01重量份的石墨烯的粘结剂。
2.比较例1
使芯层的厚度达到50μm，使粘结剂的成分不包含石墨烯，除此之外，以与上述实施例相同的条件合成了食品包装材料。
3.比较例2
使芯层的厚度达到40μm，使粘结剂的成分不包含石墨烯，除此之外，以与上述实施例相同的条件合成了食品包装材料。
实验例1：包含石墨烯的蒸煮食品包装材料与现有技术的耐久性比较
在对所制备的上述实施例、比较例1及比较例2中的蒸煮食品包装材料确认的结果，在使芯层的厚度达到50μm的比较例1及使芯层的厚度达到35μm至40μm的实施例中，确认到了水分、氧等的阻隔性，在使芯层的厚度达到40μm的比较例2中，确认到了在表面出现龟裂，并且，呈现出的水分、氧等的阻隔性降低。因此，在包含石墨烯的实施例1中，确认到具有如下的效果，即，即使芯层的厚度薄，也是耐久性及阻隔性增加，以可完整地体现蒸煮食品包装材料，确认到具有可明显减少铝使用量的优点。
实验例2：通过测定包含石墨烯的蒸煮食品包装材料与现有技术的成型破裂深度来比较耐久性
以与上述实施例相同的方法制备了蒸煮食品包装材料，并确认了基于上述石墨烯的含量的效果上的差异。具体地，对于上述粘结剂层而言，相对于100重量份的总粘结剂，添加0.0005重量份、0.001重量份、0.005重量份、0.01重量份、0.05重量份、0.1重量份、1.0重量份、1.5重量份、2.0重量份、2.5重量份、3.0重量份、3.5重量份、4.0重量份、4.5重量份、5.0重量份的石墨烯，从而制备了蒸煮食品包装材料。而且，基于石墨烯含量的效果可通过测定蒸煮食品包装材料开始破裂的成型破裂深度来得到确认。成型破裂深度意味着当薄片在被施加压力时承受并不破裂的深度。以市面上的现有技术为基准来比较判断了上述成型破裂的深度，市面上的薄片的成型破裂深度为8.6mm。表1及图2示出了结果。
[表1]
Figure BDA0002736995160000141
通过确认成型破裂结果，确认到了如下结构，在上述石墨烯的含量达到0.0005重量份及0.001重量份时，蒸煮食品包装材料的成型破裂深度达到8.6mm，与现有技术的破裂深度相同，在小于0.001重量份时，呈现出与现有产品等同的性能。并且，当上述石墨烯的含量达到3.5重量份至5重量份时，蒸煮食品包装材料的成型破裂深度达到8.5mm以下，当含量达到3.5重量份以上时，呈现出的性能比现有产品的标准低。与之相反，在上述石墨烯的含量达到0.005至3.0重量份的情况下，呈现出大于8.6mm的成型破裂深度，测定到最高9.4mm(1重量份)的深度，确认到随着添加石墨烯来呈现出比现有产品更优秀的耐久性提高效果。
并且，在上述实验例1及实验例2中仅确认了使粘结剂包含石墨烯的情况，这种结果在使上述密封剂层或上述表面层包含上述石墨烯的情况也同样出现。
如上所述的本申请的说明属于例示，本申请所属技术领域的普通技术人员可以理解，可在不改变本申请的技术思想或必要特征的情况下，能够以其他具体实施方式轻松进行变形。因此，以上记述的实施例在所有层面都是例示性的，而不应理解成限定性的。例如，以单一型说明的各个结构要素可分散实施，同样，还能够以结合的形态实施以分散的方式说明的结构要素。
本申请的范围由所附的发明要求保护范围来表示，而不是上述详细说明，应解释成从发明要求保护范围的含义、范围及其等同概念导出的所有变更或变形的实施方式属于本申请的范围。
