简介:各有关单位及专家:近年来,随着国民经济的快速发展,以高阻隔性塑料包装材料为代表的各种功能塑料技术日新月异,如抗菌塑料、抗静电塑料、易开封薄膜、收缩薄膜、弹性薄膜等方面的技术均有了长足的进步,但至今,塑料功能性包装材料技术创新仍是我国塑料包装的主要短板之一,如何缩小与国外先进技术的差距,提升行业经济效益和竞争力,是我国塑料包装行业发展由大到强的重要手段之一。基于业界的迫切需求,为促进技术交流与创新,了解新产品信息与行业未来发展趋势,整合资源,共谋发展,我会决定在2017第二届包装世界(上海)博览会期间,在上海举办“2017功能性塑料包装创新峰会暨中包联塑料委专家委员会年会”。现将相关事项通知如下:
