    Abstract: The invention relates to a plastic packaging container (10) and to a method for producing a plastic packaging container (10). A plastic packing container (10) is formed by injection molding, deep drawing, and/or blow molding, and the plastic packing container (10) is coated and/or can be coated with a barrier layer (40) and is produced with a cavity (12) for receiving a packaging content, in particular a food product, and with a sealing zone (20). Furthermore, in order to improve the sealability to a sealing material, the surface, preferably at least 50% of the surface, of the sealing zone (20) is produced with a higher average surface roughness R
    a according to DIN EN ISO 4288:1998 than the average surface roughness R
    a according to DIN EN ISO 4288:1998 of the inner surface (14), preferably at least 50% of the inner surface, of the cavity (12) and/or than the average surface roughness of the outer surface, preferably at least 50% of the outer surface, in particular the lateral surface, of the plastic packaging container, and the sealing zone (20) is produced with an average surface roughness R
    a according to DIN EN ISO 4288:1998 of at least 200 nm.

    Abstract translation: 本发明涉及塑料包装容器(10)和用于生产塑料包装容器(10)的方法。 塑料包装容器(10)通过注射成型,深拉伸和/或吹塑成型而形成,并且塑料包装容器(10)被涂覆和/或可以涂覆有阻隔层(40)并且用 (12),用于接收包装内容物,特别是食品,并具有密封区域(20)。 此外,为了改善对密封材料的密封性,根据DIN EN ISO 4288:1998,密封区域(20)的表面,优选至少50%的表面具有较高的平均表面粗糙度R a (12)的内表面(14)的根据DIN EN ISO 4288:1998的平均表面粗糙度R a,优选地至少为内表面的50%和/或外表面的平均表面粗糙度 表面,优选塑料包装容器的外表面的至少50%,尤其是侧面,并且密封区域(20)根据DIN EN ISO 4288:1998的平均表面粗糙度Ra 至少200nm。
