摘要
目前,国内包装行业多数采用恒温油浴和烘箱来进行薄膜收缩率的检测,而较少测试收缩力值。介绍了常用的收缩率测试标准,并重点介绍了ISO 14616与DIN 53369收缩力值的测试方法;采用ISO 14616的方法通过试验对低密度聚乙烯LDPE、非结晶型共聚酯PETG、单向拉伸聚苯乙烯OPS、多层共挤聚烯烃POF和双向拉伸聚丙烯BOPP等5种材料进行了测试。结果表明,该方法不仅可以检验聚乙烯、乙烯共聚物及其混合物的收缩性能,也可检验其他热收缩膜的收缩性能。
Currently,heatings by oil-bath and oven are major methods used in domestic for packaging industry to test the shrinkage ratio of plastic films,but the shrinking force and contracting force is less measured.The common shrinkage testing standards were introduced with focuses on the testing methods of shrinking force and contracting force in ISO 14616 and DIN 53369.LDPE,PETG,OPS,POF and BOPP were tested using method of ISO 14616.The results showed that ISO 14616 is available for the measurement of shrinkage properties of polyethylene,ethylene copolymers,and their mixtures as well as other heat-shrinkable films.
