Blue Ocean Closures

Blue Ocean Closures is a Swedish technology start-up founded in 2021 that specializes in the development and production of fiber-based packaging closures. The company utilizes a proprietary vacuum press forming technology to create rigid, durable, and recyclable structures from cellulose fibers sourced from sustainably managed forests. Unlike traditional plastic alternatives, these fiber-based closures are designed to be biodegradable and avoid microplastic formation, offering brands a sustainable, biobased solution that can be integrated into existing filling and packaging systems.

Headquartered in Karlstad with production facilities in Säffle, the company partners with major global brands and industrial leaders—including Coca-Cola, L'Oréal, and Absolut—to replace plastic or metal caps across beverage, nutraceutical, and consumer product segments. Supported by investment from industry partners like ALPLA Group, Elopak, and Nissha, Blue Ocean Closures focuses on scalability and cost-efficiency to help manufacturers reduce their carbon footprint and address plastic waste. Their products, such as the NutraCap line, have received industry recognition for sustainable packaging innovation and are actively being adopted by retailers and brands to meet circular economy goals.
