Question

Edible packaging has comparable water vapor transmission rates.

(a) True

(b) False

This question was posed to me in an internship interview.

This intriguing question originated from Edible, Biobased and Biodegradable Food Packaging Materials topic in portion Edible, Biobased and Biodegradable Food Packaging Materials of Food Packaging Technology

Answer 1

Right option is (a) True

Easiest explanation: Biobased polymers are generally hydrophilic in nature. So are many traditional polymers like nylon, ethylvinyl alcohol, etc. Permeability may increase when humidity increases in both cases. Hence, we can say that edible packaging has comparable water vapor transmission rates.
