Abstract: A plastic film is provided having one or more longitudinal bands with a thickness of 3 μm-50 μm thicker than the main portion of the film. Each thicker band is formed integral with the main portion of the film. Each band is in the form of a single ply. A method for producing the film includes that a molten polymer or polymer composition is extruded in a single ply and cooled, so that a film is formed. The polymer ply is cooled in one or more narrow areas before the main portion of the film is cooled. The narrow cooled areas correspond to the width and position of the thicker longitudinal band or bands. Some typical uses of the film include wrapping pallets and packaging agricultural produce.

Abstract translation: 提供具有一个或多个厚度比膜的主要部分厚3μm至50μm的纵向带的塑料膜。 每个较厚的带与膜的主要部分成一体。 每个乐队都是单层的形式。 制造薄膜的方法包括熔融聚合物或聚合物组合物在单层中挤出并冷却，从而形成薄膜。 在薄膜的主要部分冷却之前，将聚合物层冷却在一个或多个窄区域中。 窄的冷却区域对应于较厚的纵向带或带的宽度和位置。 薄膜的一些典型用途包括包装托盘和包装农产品。
