Can someone advise with what the Industry norm is for CaCO3 in blow molded items? Say for personal care items or milk jugs or motor oil cans or seats? Do companies add CaCO3 in these items to get a cost saving? How do you achieve this? What I've seen with injection molding is that the overral weight increases and if we are selling by the volume it is a loss compared to selling 100% plastic. Would you reduce thickness while keeping the weight of the item constant? Allow the weight to increase a bit while reducing thickness? How much on average could you load an item before it fails? (I know this depends on the product but what a general rule of thumb?) How about the color? Would you need to add more or less color? Or would this depend on the color and it can go either way?
Thank you for the advise.
