Description
技术领域
本发明涉及具有优异的热收缩性、并且能够抑制印刷等后续工序中发生污染的热收缩性膜。
背景技术
近年来,PET瓶、金属罐等的容器上大多装有对由热塑性树脂构成的热收缩性膜实施了印刷等的热收缩性标签。
对于热收缩性膜而言,除了要求低温收缩性之外,还要求耐热性、耐溶剂性、针孔线撕裂性等的各种性能。
另一方面,这样的热收缩性膜在进行印刷或标签加工等的后续工序时,由于热收缩性膜与金属制的引导辊等接触,出现膜的表面被切削、金属制的引导辊等被膜的切削屑等污染的问题。
对此,专利文献1中公开了通过限定膜的表面粗糙度来提高膜行进时的耐磨损特性的技术。

本发明的目的在于提供一种具有优异的热收缩性、并且能够抑制印刷等后续工序中发生污染的热收缩性膜。
用于解决课题的方法
本发明是至少具有含有55~99.99重量%的环状烯烃系树脂和0.01~0.3重量%的有机系微粒的正面背面层的热收缩性膜。
以下,对本发明进行详细说明。
本发明的发明人发现,具有以规定的比例含有环状烯烃系树脂和有机系微粒的正面背面层的热收缩性膜具有优异的热收缩性,并且能够抑制印刷等后续工序中发生污染,从而完成了本发明。
本发明的热收缩性膜至少具有含有55~99.99重量%的环状烯烃系树脂和0.01~0.3重量%的有机系微粒的正面背面层。
在本说明书中,正面背面层是指正面层和背面层两者。但是,在本发明的热收缩性膜为1层结构时,是指该膜本身。
上述正面背面层含有环状烯烃系树脂。
通过含有上述环状烯烃系树脂,能够使结晶性降低,热收缩率提高,并且膜制时的拉伸性也提高。
作为上述环状烯烃系树脂,可以列举:(a)乙烯或丙烯与环状烯烃(例如,降冰片烯及其衍生物或四环十二碳烯及其衍生物等)的共聚物、(b)该环状烯烃的开环聚合物或与α-烯烃的共聚物、(c)上述(b)的聚合物的氢化物、(d)利用不饱和羧酸及其衍生物等得到的上述(a)~(c)的接枝改性物等。
另外,作为上述环状烯烃系树脂的市售品,可以列举ZEONOR(日本ZEON公司制)、APEL(三井化学株式会社制)、TOPAS(POLYPLASTICS CO.,LTD.制)等。

另外,优选上述环状烯烃系树脂的比重为1.00~1.06。
上述环状烯烃系树脂的玻璃化转变温度优选为20~130℃,更优选为50~100℃。上述玻璃化转变温度低于20℃时,膜表面的耐热性降低,存在在安装线上容易发生容器彼此粘连的现象的趋势,还存在自然收缩率变得过大的趋势。在超过130℃时,存在横向的热收缩率变得过小的趋势。
上述正面背面层中的上述环状烯烃系树脂的含量的下限为55重量%,上限为99.99重量%。如果在上述范围外,热收缩性膜的操作性和透明性变差。

另外,上述有机系微粒之中,作为市售品,例如,可以列举Techpolymer(积水化成品工业株式会社制)、FINE SPHERE(Nippon Paint Co.,Ltd.制)、GANZPEARL(Aica KogyoCompany,Ltd.制)、Art Pearl(根上工业株式会社制)等。

本发明的热收缩性膜优选通过上述正面背面层、和含有51~99重量%的乙烯系树脂或丙烯系树脂和1~49重量%的环状烯烃系树脂的中间层叠层而成。由此,形成能够获得优异的完成度的热收缩性膜。
上述中间层含有51~99重量%的乙烯系树脂或丙烯系树脂和1~49重量%的环状烯烃系树脂。

作为上述拉伸的方法,例如,可以使用辊拉伸法、拉幅机拉伸法或它们的组合。拉伸温度可以根据构成膜的树脂的软化温度、热收缩性多层膜所要求的收缩特性等变更,优选的下限为65℃,优选的上限为120℃,更优选的下限为70℃,更优选的上限为115℃。主收缩方向的拉伸倍率可以根据构成膜的树脂、拉伸方法、拉伸温度等变更,优选为3倍以上,更优选为4倍以上,优选为7倍以下,更优选为6倍以下。通过为这样的拉伸温度和拉伸倍率,能够实现优异的厚度精度。
本发明的热收缩性膜的用途没有特别限定,本发明的热收缩性膜的针孔线撕裂性优异,耐落下冲击性优异,并且透明性也优异,因此,适合作为例如装于PET瓶、金属罐等的容器的热收缩性标签的基膜使用。

(比较例3)
作为正面层、背面层的原料,将作为环状烯烃系树脂的APL8008T(乙烯-四环十二碳烯共聚物,玻璃化转变温度:70℃,三井化学株式会社制)85重量%、作为乙烯系树脂的直链状低密度聚乙烯SP2320(普瑞曼聚合物株式会社制)15重量%混合。
除了使用该混合物以外,与实施例3同样操作,得到正面层/中间层/背面层为8μm/24μm/8μm的厚度、总厚度为40μm的膜。
(比较例4)
作为环状烯烃系树脂,使用APL8008T(乙烯-四环十二碳烯共聚物,玻璃化转变温度:70℃,三井化学株式会社制,99.5重量%),在其中添加混合作为有机系微粒的交联苯乙烯微粒(SX,平均粒径3.5μm,综研化学株式会社制)0.5重量%。
使用单螺杆挤出机以料筒温度210℃将它们的混合物熔融,从T模挤出,利用冷却至30℃的辊冷却固化,制作未拉伸片。将所得到的未拉伸片用温度90℃的拉幅式拉伸机在TD方向拉伸5倍,形成总厚度45μm的膜。
(评价)
对实施例和比较例中所得到的热收缩性膜进行以下的评价。在表1中表示结果。
(1)膜污染
对所得到的膜,使用蓝色和白色两色的印刷墨水,用凹版印刷机(富士机械株式会社制)在单面实施双色印刷。印刷图案为用蓝色印刷边长5mm的四方的格子图案,用白色印刷膜的整个面。印刷速度为120m/min。
对于印刷后的膜卷,用2次切条机(secondary slitter)(片冈机械制作所制)以150m/min卷回。此时,从膜卷的卷出部用最初的辊在印刷面与辊接触的辊上对膜的非印刷面用布头擦拭。布头用一个食指按压,以膜卷1500m/分钟擦拭。
将实施1500m/分钟的擦拭后按压布头的部分变黑的样品评价为“×”,将几乎不变黑的样品评价为“○”。
(2)动摩擦系数
对所得到的膜,使用表面性测定机(HEIDON 14FW,新东科学株式会社制)测定动摩擦系数。此时,使膜的正面层彼此接触,以荷重200g、移动速度100mm/min进行测定。
(3)热收缩率
将所得到的膜切割为MD100mm×TD100mm大小的样品,在80℃的温水中浸渍10秒之后,取出热收缩性膜,根据下式求出MD和TD的收缩率。其中,收缩率使用n=3的平均值。
收缩率(%)={(100-L)/100}×100
(4)透明性
对所得到的膜,使用NDH5000(日本电色工业株式会社制),按照根据JIS K 7136的方法测定雾度值。
[表1]
对实施例和比较例1、2进行比较,虽然动摩擦系数没有大的差异,但是比较例1、2中膜被污染而变黑。可以认为这是由于将有机系微粒变更为无机系微粒,而发生了引导辊的切削的缘故。
另外,在不含微粒的比较例3中,由于动摩擦系数变大,可知膜的表面润滑性劣化,但是不发生膜污染。因此,可知膜的表面润滑性与膜污染之间没有相关关系。
工业上的可利用性
根据本发明,能够提供一种具有优异的热收缩性、并且能够抑制印刷等后续工序中发生污染的热收缩性膜。
