无塑涂布纸杯纸涂料的性能实验

Performance Experiment of Non-plastic Coated Cup Base Paper

禁塑令颁布实施在即,必然会对淋膜法生产一次性纸杯产生影响,故积极开发无塑涂布纸杯纸很有必要。本文进行了两种进口无塑纸杯原纸涂料的性能对比实验。结果表明:进口涂料生产的纸杯纸在抗热水渗透性、抗油性、抗酒精渗透性及热封合效果等方面仍存在一些问题。尤其是热封合时因加热造成涂层发黏的情况,是纸杯纸开发过程中必须解决的问题。

It is necessary to develop non-plastic coated paper cups after the implementation of the plastic ban order,which may have an impact on the production of PE coated cups.In this paper,two kinds of imported non-plastic paint for base paper were compared,and their applicability was introduced in detail.The results show that the cup paper using imported coatings still has some problems in hot water permeability,oil resistance,alcohol permeability,and heat sealing effect.The coating is easy to become sticky after heating during heat sealing,which can be a problem that must be solved during the development of paper cups.
