Shrink Bags
High barrier Shrink packaging represents the high-tech trends of packaging. Shrink bag is made from shrink film. When heat is applied, it shrinks tightly over whatever it is covering. The whole package is put in water after vacuumed. Then heating to 85-90 °C ,the film edge is tightly wrapped around the product. The excellent elasticity makes sure of perfect packing and keeps pressure away.
1.Ideal packaging for fridge and frozen storage.
2.Excellent shrinkage rate help to save courier cost.
3.PVDC layer contributes to keep food fresh extend shelf life.
4.Customized bag type ,thickness and printing to meet different requirements.
