Food packaging is quite different from cosmetics, industrial or perfume packaging since food packaging involves food and there is always a health concern due to contamination. Food packaging means selecting a packing material for storing food products, ensuring that there is no additional smell or odor from the packaging material and also ensuring that the content is kept safe and free from any kind of contamination.
After considering the above factors, manufacturers need to think about their budget constraints while remembering that customers will definitely look for something which is attractive. Looking good, attractive with proper images and convenient handling is also of prime importance when packaging products. Moreover, any food packaging material has to be lightweight since the content inside will have a weight of its own and additional weight of the package is certainly not welcome.
