应用说明

用于饮料工业贴标应用的聚烯烃类压敏热熔胶在大规模生产、品牌、冲动性消费、以及便捷性等客观因素影响下,正确选择标签粘合剂是成功的重要因素。良好的外观是对标签与粘合剂的最基本要求,不脱落,不被冲洗掉以及不能随意折叠影响标签信息传播是其它比较重要的方面。一款理想的标签用粘合剂不仅要使标签粘接牢固,可以灵活的、干净的粘接在饮料瓶上,同时手持过程中要使标签具有良好的触感。PET基材与可回收处理的薄层饮料瓶需要具有高柔性的抗冲击标签,以吸引客户的目光。

聚合物可以用于提供内在强度,胶层的内聚力。现今,根据客户需求订制的聚烯烃类聚合物作为原材料的一种,非常适用于制造标签类粘合剂,主要原因在于平衡的内聚特性给予粘合剂的高强度与优异的柔韧性。全新的胶王Jowat-Toptherm® 热熔胶提供了更高的初始强度,其在粘接包膜与分拆纸标签时是首选用胶,使得每小时饮料瓶的产量可以达到48,000个。

生产部门可以从聚烯烃类热熔胶的低工艺成本当中获益。在封箱的应用领域 ,此类热熔胶的各种优势已被客户所熟知,而如今聚烯烃类热熔胶在标签粘接领域得到广泛应用。以聚烯烃为基材,使得之前使用EVA和橡胶基热熔胶时的一些缺点如燃烧,裂
解和开胶等问题得到解决。在施胶过程中,减少拉丝现象,以及优异的耐热性能,减少了清洗环节,延长了设备维护的时间间隔。新的原材料具有稳定的粘度,在应用过程中,提供了良好的流动性与转移性。
