About Solarae
Solarae Foshan: Sustainable Plastic Caps for Food, Cosmetics, & Household Products
Since 2010, Solarae has operated from Foshan, China — a manufacturing hub known for efficiency and innovation. We specialize in recyclable plastic caps for diverse industries, combining local supply chain advantages with a commitment to sustainability. Our products, from food-grade closures to chemical-resistant fuel caps, prioritize functionality and environmental responsibility.
From Local Roots to Global Reach
Founded as a small workshop serving Foshan’s detergent brands, Solarae initially focused on basic HDPE caps. By 2015, investments in semi-automated molding machines allowed us to expand into cosmetics and skincare packaging. A pivotal moment came in 2018 when we secured our first EU client — a German organic skincare brand — which drove upgrades in material standards (e.g., FDA-compliant rPET for food caps) and recycling processes. Today, 70% of our raw materials are sourced from Foshan-based recycled plastic suppliers, supporting clients in 20+ countries.
