Starbucks Korea Pilots Sugarcane Straws, Innonature Packaging Solutions Develops Cork Sleeve for Bottles, and Akorn Technology Launches Edible Coating for Cucumbers

Innonature Packaging Solutions offers cork-based bottle sleeve as a reusable and recyclable alternative

Innonature Packaging Solutions, based in Europe, has developed a reusable and recyclable sleeve for wine and spirits bottles made from cork, launched in collaboration with Dubai Duty Free. The sleeve is created from sustainably sourced cork derived from cork oak trees (Quercus suber), which are known for their ability to regenerate bark without requiring the tree to be felled. The cork used is harvested every 7–9 years, with each tree able to provide up to 17 harvests over its lifetime. This harvesting method is considered to offer environmental benefits, with harvested trees reportedly absorbing three to five times more CO₂ than unharvested ones. The cork material is sourced from FSC-certified forests in Portugal, and the manufacturing partner holds ISO 45001 and SA 8000 certifications, with production supported by renewable energy sources such as solar and cork dust biomass. The Suber Sleeve is lightweight, moisture-resistant, and can be flat-packed to improve transport efficiency and reduce emissions. In addition, it features a QR code linking to information about the sleeve’s sourcing, environmental impact, and reuse options. The design is customisable to meet brand-specific requirements and is targeted at organic wineries, spirit brands, and retailers seeking sustainable packaging. The product aligns with EU packaging legislation requiring recyclability or reusability by 2030. 

The coating is intended to meet the growing interest in the US, Europe, and elsewhere for sustainable, compostable alternatives to plastic, which contributes to pollution and can accelerate spoilage. ThePackHub

Akorn Technology replaces plastic wrap for cucumbers with edible plant-based coating 

Berkeley, California-based startup Akorn Technology has launched a natural, edible coating designed to replace single-use plastic wraps on cucumbers while maintaining freshness and extending shelf life. Branded as Akorn Natural Advantage, the coating forms an invisible barrier on the surface of cucumbers and bell peppers, emulating the protective role of plastic without the associated environmental impact. Produced from upcycled, non-GMO plant materials, the patented formulation is applied directly to the vegetables and is safe for consumption. According to Akorn, cucumbers treated with the coating retain a vibrant green color, glossy finish, and firm texture, addressing issues such as ethylene build-up in plastic-wrapped cucumbers that can lead to yellowing and loss of crispness. The coating is intended to meet the growing interest in the US, Europe, and elsewhere for sustainable, compostable alternatives to plastic, which contributes to pollution and can accelerate spoilage. Akorn highlights that the solution can be integrated into existing packing lines with only minor adjustments, making it a practical option for retailers and producers. The company also points to studies showing that loose produce or breathable, compostable packaging helps reduce both food waste and plastic usage, aligning with environmental and consumer preferences for sustainable packaging in the fresh produce sector.
