There are scores of packaging materials to choose from, but here are the general categories.
Plastic
One of the biggest misconceptions about plastic packaging is that there is only one kind. Microwaveable containers are made of heat-resistant polypropylene, while CPET containers can withstand extreme cold. Other popular plastics are PET (e.g. drinkable liquids) and polystyrene (e.g. clear take out trays).
Metal
Aluminum and steel are the most common metals used in packaging. Metal gives a good level of protection to food
