ISO 18263-1:2015建立了一个系统，可作为聚丙烯（PP）和聚乙烯（PE）回收物混合物规范的基础。 它涵盖了聚丙烯（PP）和聚乙烯（PE）的混合物，回收物来源于PP和PE，用于模塑和挤压的柔性和刚性消费品包装。不得使用用于运输、搬运或储存危险品的包装回收物。 它不适用于回收物和原始树脂的混合物。 不适用于含有特殊类型PE或PP的混合物，例如PE-UHMW、TPO等。 PP和PE回收物混合物的类型通过基于指定性质的适当级别的分类系统相互区分。 a） 构图 b） 熔体质量流量 c） 密度 d） 颜色 这并不意味着具有相同名称的材料必然具有相同的性能。ISO 18263-1:2015未提供工程数据、性能数据或加工条件数据，这些数据可能需要用于指定特定应用和/或加工方法的材料。如果需要额外的性能，应根据ISO 18263-2规定的试验方法（如适用）进行测定。

ISO 18263-1:2015 establishes a system which can be used as the basis for specifications for mixtures of polypropylene (PP) and polyethylene (PE) recyclate. It covers mixtures of polypropylene (PP) and polyethylene (PE) recyclate derived from PP and PE used for flexible and rigid consumer packaging for moulding and extrusion. Recyclate from packaging used for the transport, handling, or storage of hazardous goods shall not be used. It does not apply to mixtures of recyclates and virgin resin. It does not apply to the mixtures containing special type of PE or PP, for example, PE-UHMW, TPO, etc. The types of mixtures of PP and PE recyclate are differentiated from each other by a classification system based on appropriate levels of the designatory properties. a) Composition b) Melt mass-flow rate c) Density d) Colour It is not intended to imply that materials having the same designation give necessarily the same performance. ISO 18263-1:2015 does not provide engineering data, performance data, or data on processing conditions which may be required to specify a material for a particular application and/or method of processing. If additional properties are required, they shall be determined in accordance with the test methods specified in ISO 18263-2, if applicable.
