Now here comes the 2nd most important function of Packaging - Protect & Preserve.
Yes, protect and preserve functions goes hand in hand, and the companies and managers need to first understand the physical damages and preservation method before selecting the packaging material.
Protect - It means, protection from physical damages such as vibration, shock, temperature and humidity, tamper-proof etc.
Preservation - It means, preventing the product's nature from bio-chemical and analytical changes such as impact of various gases, light, food spoilage, deterioration etc.
The most obvious function of any Packaging is Contain.
Its the first step to be considered for designing a package. We have to first understand the product's type, its form, its usage and its nature/reactivity, so the selected packaging can deliver the desired Contain function.
