    Abstract: A plastic film (1) has one or more longitudinal bands (3) with a thickness of 3µm - 50µm thicker than the main portion of the film (1). Each thicker band is formed integral with the main portion of the film (1). Each band is in the form of a single ply.
    A method for producing the film (1) includes that a molten polymer or polymer composition is extruded in a single ply (7) and cooled, so that a film (1) is formed. The polymer ply (7) is cooled in one or more narrow areas before the main portion of the film (1) 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 (1) include wrapping pallets and packaging agricultural produce.

    Abstract translation: 塑料薄膜（1）具有比膜（1）的主要部分厚3μm〜50μm厚的一个或多个纵带（3）。 每个较厚的带与膜（1）的主要部分形成一体。 每个乐队都是单层的形式。 制造薄膜（1）的方法包括将熔融聚合物或聚合物组合物挤出在单层（7）中并冷却，从而形成薄膜（1）。 聚合物层（7）在薄膜（1）的主要部分被冷却之前在一个或多个窄区域中冷却。 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（1）的一些典型用途包括包装托盘和包装农产品。
