                            真空袋包装越来越多样化

                            为了使包装更加美观、耐腐蚀,食品真空包装袋的使用要注意四点。塑料袋薄膜呈乳白色,半透明状(几层叠起来观察尤其明显),摸起来较润滑,好像表面上涂有蜡层,用力抖动,声音发脆,遇火易燃,火焰黄色,燃烧时有粘液滴落,并有蜡烛燃烧时的气味。牛皮纸食品包装袋具有环保、简约、美观等优点,被各大食品厂商以及广大消费者深深喜爱着,所以牛皮纸逐渐被运用得更广范围。食品包装袋外壳可以使食物与氧气、水蒸气、污渍等隔开,防渗漏亦是包装设计的必要因素。一些包装涵括了干燥剂或脱氧剂用以延长保质期。真空包装或抽去包装袋中的空气也是主要的食品包装方法。保存食物在保质期内的干净,新鲜和安全是包装袋的首要功能。尽量选择无涂层、无涂层的食品真空包装袋。在现代包装设计中。广泛使用涂层数据。这不仅给产品报废后数据的回收和再利用带来了困难,而且大部分涂料本身也是有毒的。如果人们吃包装在这些食物袋里的食物,将会对人们的健康造成很大的危害。此外,镀膜、电镀工艺也给环境带来了很大的污染。如油漆挥发性有毒溶剂气、电镀含铬等重金属废液、废渣污染等。因此,我们应该尽量选择没有涂层和涂层的食品真空包装袋。
