Revolutionizing Shelf-Stable Liquid Dairy Packaging with Husky’s Sustainable Multi-Layer Solutions


In today's beverage packaging landscape, sustainability is a dominant trend driving the evolution of the industry. Consumers are increasingly demanding eco-friendly solutions that are recyclable, have a reduced carbon footprint, and comply with circular economy principles and regulations.

One example is the new Circular Economy Law that Mexico approved at the end of 2021, which impacts the manufacturing, processing, production, and import of packaging containers. The law requires companies to gradually increase the percentage of recycled content in their packaging, with the goal of achieving 100% recycled content by 2030.

Among the products in this context are shelf-stable liquid dairy beverages (the reference to shelf-stable liquid dairy beverages includes plant-based dairy alternatives throughout this article), which require protection from light to maintain their quality and flavor.

Sensitivity of Liquid Dairy to Light

The rising demand for shelf-stable liquid dairy beverages, especially among health-conscious consumers, has led to a need for packaging that safeguards these products from light-induced deterioration. Both dairy and plant-based beverages are susceptible to the creation of off-flavors when exposed to light. To address this challenge and comply with new regulations, shelf-stable liquid dairy manufacturers are investing in innovative packaging solutions.

Packaging Options for Shelf-Stable Liquid Dairy

Traditional packaging materials like paperboard cartons and HDPE bottles that contain titanium dioxide have been used to block light. However, these options have limitations, such as difficulties in recycling and high material costs. On the other hand, PET materials offer a more sustainable choice due to the high recyclability, but they require opacifying additives or light-blocking sleeves, which may increase costs and complicate recycling.

Introducing Light-Blocking Co-injected PET Bottles

Husky's sustainable multi-layer PET bottles offer an innovative solution to address the challenges of light protection and sustainability. Co-injected PET bottles have a functional core layer that entirely blocks light transmission, reducing the need for expensive white colorants.

Moreover, the use of post-consumer recycled PET (rPET) in the core layer provides a sustainable solution for opaque rPET that would otherwise go to waste.
