Indeed, one does not become a packaging technician overnight. You must learn all the different materials of packaging, the difference between corn-based and artificial peanuts and how they are to be aligned, the difference between air-spaced and cemented bubble wrap, how to Zydeco-test the cardboard, and perhaps the most difficult part of the job, how to read the postage chart. Once you've learned all that, THEN you can begin your 5-year apprenticeship.
