摘要:
A mulch barrier film having, for example, a methyl bromide permeability of less than about 15 g/m 2 -hr and machine direction Elmendorf tear strength of at least about 75 gf. The mulch barrier film is an extruded, cast, and preferably embossed, multilayer film having at least one polyolefin layer and at least one polyamide layer. The combination of the film structure and the casting process achieves a barrier film that has low permeability to volatile soil treatment chemicals, such as methyl bromide, and superior tear strength properties.
摘要(中):
具有例如小于约15g / m 2·小时的甲基溴渗透率和至少约75gf的机器方向埃尔门多夫撕裂强度的覆盖膜阻隔膜。 覆盖屏障膜是具有至少一个聚烯烃层和至少一个聚酰胺层的挤压,浇注和优选压花多层膜。 膜结构和铸造工艺的组合实现了对挥发性土壤处理化学品(例如甲基溴)具有低渗透性和优异的撕裂强度性能的阻挡膜。
