食品包装材料需要具备几种特性,包括:密封性好,低萃取,以及可延长食品保质期等。消费者对包装内容物的知情诉求以及对琳琅满目商品的视觉疲惫,直接促使现在大多数食品包装都需要通过透明和颜色鲜艳的材料来吸引消费者的注意力,也为热塑性弹性体产品应用于食品行业提供了很好的机会。
1用热塑性弹性体做食品包装,有几大好处:
第一,它能够与不同的塑料结合在一起,外观和手感都很好;
第二,具有良好的耐化学性以及在不同环境中的稳定性,比如耐紫外线,即在长时间光照下不容易变色;
第三,几乎没有气味和味道;
另外,热塑性弹性体还有一个最大的优势,就是它便于回收。

注意事项Matters need attention |
||||||||
清洗料管 Purge compound |
需使用PP或 PE清洗干净机台螺杆,且把机台射嘴彻底清除干净Please make sure you that you have cleaned the machine screw with PP or PE, and put the machine nozzle thoroughly clean. |
|||||||
着色 Coloring
|
请选择以PE或EVA为基材之色母,切勿使用以PVC为基材者。另外加工时请采用较高的螺杆转速和较高的背压,才能让着色剂达到较好的分散效果Please select color master batch on PE or EVA material with the exception of PVC.Higher screw speed and backpressure are needed for better colorant dispersion. |

回收 Recycling |
二次料(水口料)回收比率建议最多10%. Consistent regrind usage of up to 10% is permissible. |
