How to choose the material for your Plastic handle knife?

What material for the knife handle.

برای plastic handle kitchen knife,we suggest use new material instead of old material for plastic handle knife.

Maybe someone will ask,I want to lower the price,can I used old PP material to instead of new PP material?Well,it can a little bit cheaper,but they are not a big price different and it is not good for your sales. I do not suggest you used old material.I know old material is about USD0.5-0.6/KG lower than new material,but do you know what,for the same size handle,old material پلاستیک is heavy than new material پلاستیک,and old material’s defective rate is higher.Second:if your kitchen knife’s handle is not black but colorful,if we use old material,the handle’s color is not as bright as new color,and if you want to place reorder next time,it is hard to get the same color as last time.
