Compared with other films, BOPA metallized film has higher strength and excellent gas barrier properties, and is non-toxic and harmless. It is an ideal material for food preservation and aroma preservation. The composite film materials combining VMBOPA with CPP or PE are widely used in food packaging, chemical and pharmaceutical product packaging, and decorative balloons, etc.
