Description

薄膜及其加工方法
技术领域
本发明涉及到一种薄膜及其加工方法。 
背景技术
日常生活中，塑料薄膜及其制品有着越来越多的用途，特别是食品行业中应用较多，因为在食品生产过程中必须用到塑料薄膜制品(围裙、帽子、包装袋、手套等)，但是在使用塑料薄膜制品的时候，或多或少会发生脱落，例如摩擦或被其它金属或器材碰到时，有少量薄膜屑或碎片掉落，如果薄膜屑或碎片掉落到食品中，那么势必会污染食品，一旦忽视，被误食，对人体的健康会产生影响，在实际生产的时候，很少有企业对食品的加工进行严格的把关，而且也没有特定的器械对食品进行检测。 
发明内容
本发明所要解决的技术问题是：提供一种可被金属探测器检查出的薄膜及其加工方法。 
为解决上述技术问题，本发明采用的技术方案为：一种薄膜，包括占总重量85％～90％的聚乙烯，占总重量2％～5％的金属粉末，占总重量4％～5％的开口剂，占总重量4％～5％的干燥剂。 
所述金属粉末呈直径小于0.1mm的颗粒状。 
所述金属粉末为铁、钨、钼、铜、钴、镍、铝、锡、铅中的一种或多种。 
薄膜的加工方法，所述将占总重量85％～90％的聚乙烯，占总重量2％～5％的金属粉末，占总重量4％～5％的开口剂，占总重量4％～5％的干燥剂加入到搅拌机内搅拌，搅拌均匀后，将搅拌均匀的物料放入流延机上的料桶内，然后经流延机中的螺杆和模具挤出后通过压纹辊和硅胶辊压制而成。 
所述，其中螺杆工作温度为180℃～240℃，模具的工作温度为180℃～240℃， 利用压纹辊和硅胶辊的冷却作用，将薄膜冷却至5℃～30℃。 
本发明的有益效果是：在PE薄膜中加入金属粉末后，一旦薄膜屑或碎片掉入到食品或者例如化妆品溶液等对人体健康安全要求很高的产品中时，可以利用金属探测器探测出产品中是否含有薄膜屑或碎片，如果有，侧作相应处理，如无，则可以直接通过，进行后续工作。 
具体实施方式
下面详细描述本发明的具体实施方案。 
薄膜，一种薄膜，包括占总重量85％～90％的聚乙烯，占总重量2％～5％的金属粉末，占总重量4％～5％的开口剂，占总重量4％～5％的干燥剂。 
所述金属粉末呈直径小于0.1mm的颗粒状，这样便于将薄膜做成厚度小于0.1mm。 
所述金属粉末为铁、钨、钼、铜、钴、镍、铝、锡、铅中的一种或多种。 
薄膜的加工方法，所述将占总重量85％～90％的聚乙烯，占总重量2％～5％的金属粉末，占总重量4％～5％的开口剂，占总重量4％～5％的干燥剂加入到搅拌机内搅拌，搅拌均匀后，将搅拌均匀的物料通过送料机送入流延机上的料桶内，然后经流延机中的螺杆和模具挤出后通过压纹辊和硅胶辊压制而成。 
所述，其中螺杆工作温度为180℃～240℃，模具的工作温度为180℃～240℃，利用压纹辊和硅胶辊的冷却作用，将薄膜冷却至5℃～30℃，这样能保证金属粉末和PE很好的结合在一起。在PE薄膜中加入金属粉末后，一旦薄膜屑或碎片掉入到食品或者例如化妆品溶液等对人体健康安全要求很高的产品中时，可以利用金属探测器探测出产品中是否含有薄膜屑或碎片，如果有，则作相应处理，如无，则可以直接通过，进行后续工作。当然薄膜可以制成多种产品，用于多种场合，只要是对于需要检测产品中是否含有薄膜屑或碎片的都可以用。
