Dear Members,

Our company want to produce one article "Watering Can" - the process will be made by the blow mold equipment, we have the HDPE (prime granules special for 10 L water can) + green masterbatch granules to make the green color.

The problem that we encounter is that the surface of the water can need to be shining (shining green) - what we will need to add for the HDPE to make the shining surface?

Thank you
