Flexible packaging and its successful application in the dairy industry

Adequacy of flexible packaging to the challenges of the dairy industry

The global progress of the packaging industry is driven more specifically by the evolution of flexible packaging, and the drivers are largely e-commerce, innovation and sustainability trends.

Collaboration and supply chain initiatives are already underway as the need for action increases. Flexible packaging presents a unique opportunity for dairy industry members who face similar challenges and expectations for sustainability.

The role of flexible packaging in reducing food waste and extending shelf life

Food waste is a global issue from the perspective of consumers and retailers. In fact, it is estimated that around 21% of the waste that goes to landfill is food; dairy products make up around 17% of this. As a result, food waste contributes to global methane and greenhouse gas emissions, as well as to global food insecurity.

Shelf-life extension is one tangible method to reduce food waste. If retailers can keep food on the shelves or consumers can store it for longer, they will throw away less food and reduce the negative impact on the environment. Flexible packaging technologies such as modified atmosphere packaging, vacuum packaging and active packaging allow shelf-life to be extended. For example, cheese stored in flexible packaging is edible for up to 280 days, compared to cheese packaged using traditional packaging methods, which is only edible for up to 190 days.

Integration with smart technologies

Advances in technology are not bypassing innovations in packaging. A typical example is the use of print technology to communicate with end users through packaging - via product information, shelf life, etc. Colour indicators on packaging can change according to safe consumption periods and warn consumers. In addition, smart packaging could provide information on reliable recycling options and locations in a region.

Optimisation for e-commerce

E-commerce options for home delivery of food products should invariably satisfy consumer expectations without compromising food quality.
The barrier properties of flexible packaging can provide additional protection and insulation tailored to the requirements of each product and most product contact points compared to good, old-fashioned shopping. Multi-layer structures ensure better adhesion and prevent spillage; protect against oxidation, cross-contamination, etc. Overall, flexible packaging can be a key component in deliveries with a reduced environmental footprint due to its lightweight and compactness.

Ensuring a bright future for flexible packaging is a complex objective that will depend on consideration of the needs of consumers and key players in the supply chain. Although we cannot predict the future, we can say with great confidence that the trends described above will continue to influence the dairy industry.
