奶白聚乙烯热封膜是一种专门为低温热封工艺设计的符合包装材料,主体成为为聚乙烯(PE),通过添加乳白色母料实现遮光性与美观度。

拓普斯的奶白聚乙烯热封膜采用最新的树脂、添加剂和挤出技术,具有多种优异的性能特性。
*除非另有说明,所有性能测试均在标准实验室条件下进行:温度 23 ± 2 ºC;相对湿度 50 ± 5%。在相关情况下,测试基于国际测试标准。
兼具功能性、美观性的包装材料
可在含粉尘/油渍(≤5%)环境下正常热封。
材料兼容性强,可匹配各种材质印刷基膜。
适用立式(VFFS)/卧式(HFFS)自动包装线。
相比CPP热封膜具有一定的成本优势。
符合食品接触材料标准,无溶剂残留。
Film enters the MDO stretching unit and is evenly preheated to a required temperature.
Film is nipped between a series of rollers revolving at various speeds for stretching.
Film is stabilized, and its altered properties are locked and retained.
Film is cooled to near room temperature.

Common PE films perform high strength, high stiffness, heat resistance, easy tearing at MD and high transparency. It is suitable for the printing layer of mono PE packaging replacing PET.
High barrier MDOPE has coating barrier layer or extrusion barrier layer, achieving excellent oxygen barrier and aroma preservation.
Thickness:20-40um
Width:500-2200mm


Extremely high barrier MDOPE film performs excellent water vapor barrier property. Special formula films enhance both oxygen barrier and aroma preservation. It is available for product packaging with higher requirement on shelf life.
Thickness:21-40um
Width:500-2200mm
