GREENWICH (CHINA) TECHNOLOGY DEVELOPMENT LIMITED

BOTEC (Blue Ocean Algae Membrane) pioneers nature-derived, plastic-free packaging films using seaweed. A subsidiary of Green Fresh Group (HK: 1084), we transform marine biomass into crystal-clear films designed to deliver packaging functionality—and return safely to nature. Built on Green Fresh Group’s 30-year heritage in hydrocolloid manufacturing, BOTEC brings deep material science into practical packaging innovation. Our proprietary fromSeaweed technology enables fully bio-based film solutions developed for real converting workflows, including envelope and box window films, paper-integrated packaging windows, overwrap applications, and project-based label/sticker material options.
