- not biodegradable
- Paperboard
- biodegradable
- lightweight
- recyclable

- Plastic
- Modified Atmospheric Packaging (MAP)
- extends shelf life of fresh foods
- food is sealed in plastic packaging with oxygen, carbon dioxide and mitrogen
- extends shelf life
- once opened, the food has a normal shelf life
- Vacuum packaging
- used for dry foods, and meat and fish
- sealed in oxygen-free conditions
- extends shelf life
- Nano technology
- nanoparticles can make packaging stronger, lighter and more heat resistant
- can extend shelf lfie
- nanoparticles kill harmful bacteria
- nanoparticles make plastic better at keeping out moisture
- 'smart packaging'
- nanoparticles can change the packaging's properties depending on the conditions
- e.g. milk cartons change colour when the milk goes off
- nanoparticles can change the packaging's properties depending on the conditions
- Purposes
