How do you package powdered foods before shipping it to a fulfillment center in the U.S? the manufacturer is shipping in drums and does not package in custom printed 100g-500g Matte aluminum foil zip lock bags that I would like. The best things i can think of is me having to package it all and then sending it to the fulfillment center (paying for shipment again) or sending from manufacturer in China to a packaging company in China and then sending to U.S fulfillment center. Is there a better way to do this? how do the big companies do this?
