Testing

What’s the normal proportion?

The normal proportion is 2% - 4%. But it is not fixed. It depends on the buyer's requirement.

How does the buyer use the masterbatch?

Mix the material and the masterbatch together by the blender mixer according to the appending proportion. If no blender mixer, it can be manual mixed.

Could you give an example for using masterbatch?

For example: Put 100kg PE material and 4kg PE masterbatch into the blender mixer. Continue the film blowing process as normal.

How do the customers customize color?

Customers offer to us the sample of color sheet as the required color. We make our own samples according to customer's sample sent to us.

Is there other way to get the desired color?

We send our sample to customer for test. We produce according to orders after the sample got approved by the customers.

Do we provide free sample of the products?
