Target
Target is to develop plastic containers for all types of coffee products, such as coffee beans, roasted coffee powder and soluble coffee powder. Each kind of coffee needs specific properties in terms of barrier and aesthetic. Goal of this packaging development is the conversion from other packaging as metal can, multilayer package, glass, other plastics.Development & challenges
To develop a special family of containers for each kind of coffee is a challenge because each one of them needs special features. Soluble coffee (commercialized for the first time by Nescafé on 1938) needs protection from humidity, so the wall thickness of the final packaging is very important. Beans need protection from all elements in the environment: light, oxygen, CO2 release, linked to requested shelf-life; scavenger, passive barrier and colorant must be added to PET.Results & packaging features
