超高阻隔单向拉伸聚乙烯膜 （MDOPE-S）是一款新型的超高阻隔环保材料，通过使用镀铝MDOPE提高单一材质复合膜的阻隔性能，实现替代铝箔 。
拓普斯的MDOPE-S具有超高的阻隔性能，可实现氧气透过率低于0.1，水蒸气透过率低于0.4，可有效延长包装内容物的保质期.
*Unless otherwise stated, all performance is tested under standard laboratory condition: 23 ± 2 º C; 50 ± 5% RH.In relevant cases, testing is base on international testing standards.
产品应用
超高阻隔性能，替代铝箔、镀铝PET
具有高拉伸强度、挺度，MD方向直线易撕等优异性能。
单向拉伸膜表面平整光滑，为镀铝提供了良好的基底，能获得均匀、致密、光亮的铝层。
具有超高的阻隔性能，可实现氧气透过率低于0.1，水蒸气透过率低于0.4，能有效延长包装内容物的保质期.
可用于常温及冷冻保存包装。
相比铝箔或更厚的复合结构，镀铝单向拉伸聚乙烯膜能以更薄的厚度提供良好的阻隔性和强度，有助于减轻包装重量，降低运输成本和材料消耗。
MDOPE-T Film(Common) is a rigid film that provides excellent package stability with a straight and easy tear in machine direction.
A high modulus and use of high-quality resins ensure MDOPE-E Film (High Barrier) grade’s machinability on any printing and converting line
High stiffness, heat resistance, easy tearing at MD and high transparency. It is suitable for the printing layer of mono PE packaging replacing PET
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
