Aldi uses thermochromic label to indicate optimal wine serving temperature

Aldi, headquartered in Essen, Germany, has introduced a packaging feature for its Specially Selected Rouge Clair wine that incorporates a thermochromic label designed to indicate when the product has reached its optimal serving temperature. This smart packaging element uses temperature-sensitive ink technology that changes color in response to specific thermal conditions, providing a visual cue to consumers without requiring additional devices or tools. The label is integrated directly onto the bottle, maintaining compatibility with existing glass packaging formats while adding a functional layer of communication. By signalling when the wine is suitably chilled, the packaging aims to improve the consumption experience, particularly for red wines that benefit from being served slightly below room temperature. From a technical perspective, thermochromic inks are formulated to respond within defined temperature ranges, enabling precise calibration to the desired serving conditions of the product. The application of such inks does not significantly alter the recyclability of the primary packaging, although it introduces an additional material component that must be considered within labeling and ink systems.

The sachet’s geometry has also been modified to a narrower and more flexible format, improving ergonomics by allowing it to fit more comfortably into sports apparel, hydration belts, and pockets.ThePackHub

Z2 Performance's easy-tear sachet design improves usability for sports nutrition packaging

Z2 Performance, a sports nutrition company based in Brazil, has redesigned its energy gel packaging with a focus on improving usability and functionality for endurance athletes. The updated sachet, developed in partnership with flexible packaging manufacturer Gualapack, addresses key challenges associated with on-the-go consumption during high-intensity activities such as running, cycling, and triathlon. A central feature of the redesign is the introduction of an assisted easy-tear system incorporating side micro-perforations, enabling one-handed opening without the need for excessive force or the use of teeth. This is particularly relevant in conditions where users may have reduced dexterity, such as sweating or movement at speed. The sachet’s geometry has also been modified to a narrower and more flexible format, improving ergonomics by allowing it to fit more comfortably into sports apparel, hydration belts, and pockets, while reducing friction during movement. In addition, the packaging integrates an “eco-leash” feature, which prevents the torn tip from detaching, thereby reducing litter generation during use. From a material perspective, the structure includes a multi-layer laminate of aluminum and PET, designed to maintain barrier properties that preserve the stability, viscosity, and freshness of the gel formulation under varying temperature conditions.
