Extrusion Asia Edition 1-2019

在2019年欧洲ICE（国际纸 品胶片薄膜加工印刷技术设备及 材料博览会）期间，德国夫琅和 费研究院应用高分子研究所 （IAP）、界面工程和生物技术研 究所（IGB)以及有机电子学、电 子束和等离子技术研究所(FEP)推 出了用于食品包装的可持续的创 新技术。这些研究所中的每一个 都在加工、工艺开发和控制、特 种高分子薄膜的开发以及包装工 业超薄层沉积等方面有着丰富的 经验。 At ICE europe 2019, the German Fraunhofer Institutes for Applied Polymer Research IAP, for Interfacial Engineering and Biotechnology IGB and for Organic Electronics, Electron Beam and Plas- ma Technology FEP presented inno- vative technologies for sustainable food packaging. They each have ex- tensive expertise in processing, process develop- ment and control, the development of special 产品和食品包装的课题比以往任何时候都更为受到关切 和更为现实。 当购买和挑选塑料包装的肉类和蔬菜时，几乎 每个人的脑海中都会浮现出海洋中巨大无比的塑料漩涡。 最 后，当食品存放到家中时，外包装的数量就变得清晰了。总 的来看，来自联邦环境局的数据表明，每年每个德国人会产 生大约220千克包装废弃物。 然而，全部停止使用包装薄膜是不现实的。这是因为细 菌、病毒和霉菌无处不在，很容易使食物变质，导致严重的 疾病。从卫生标准、运输方式以及让最终消费者能够用可承 受的价格购买到新鲜食品等方面来考虑，都要求采用卫生、 实用和安全的包装。 含有抗菌精油的纳米管 开始于2017年的欧盟联合计划项目“纳米包装”,重点正是 应对这些挑战，目标是采用天然纳米材料，开发出当代最先 24 正在研发中的包装薄膜 Extrusion Asia Edition 1/2019 食品更安全，同时减少浪费 Packaging Films – From the Research: Safer Food – Less Waste 1.25米宽的薄膜基材放置在atmoFlex 1250辊到辊涂覆生产线上 (© Fraunhofer FEP) 1.25 meter wide film substrate on the roll-to-roll coating line atmoFlex 1250 (© Fraunhofer FEP) T he topic of product and food packaging is more relevant and more present than ever. Almost everyone already has the image of the immeasurably large plastic vortex in the oceans in mind when shopping and selecting plastic-packed meat or vegetables. At the latest when food is stowed at home, the amount of outer packaging becomes clear. The figures from the Federal Environment Agency speak for themselves – in total, every German produces around 220 kilograms of packag- ing waste annually. A complete avoidance of packaging film, however, is hardly feasible. Hygiene standards, transport routes and ultimately the purchasing behavior of customers with regard to fresh food at affordable prices require hygienic, functional and safe packag- ing, because bacteria, viruses and moulds can easily spoil food everywhere and can also cause serious illnesses. polymer films and the deposition of ultra-thin layers for the packaging industry.
