How do you explain material structure to a non-technical customer?

Show some samples for same product as the customer, and explain the advantage.
For example, for milk powder product, I will send a milk powder roll's picture, and say"it aluminum foil laminated structure, with the best barrier performance, very nice choice for high level milk powder with long shelf life."
