Shellac is a natural resin that has been used for centuries across industries ranging from food and pharmaceuticals to wood finishing and electronics. Derived from the secretions of the tiny insect Kerria lacca, shellac is one of nature’s most versatile materials, prized for its biodegradable, non-toxic, and film-forming properties. Despite its long history, many still misunderstand what shellac is and how valuable it can be in today’s eco-conscious world.
The production of shellac begins with Sticklac, which is the raw form of the resin found encrusting the branches of host trees in countries like India and Thailand. After being harvested, Sticklac is crushed, washed, filtered, and dried to become Seedlac. From Seedlac, various forms of processed shellac are created, including Dewaxed Shellac, Hand Made Shellac, Machine Made Shellac, and Bleached Shellac. Each type has unique characteristics, color profiles, and impurity levels suited to different applications.
Shellac is particularly well-regarded for its ability to form a natural, glossy, and protective coating. In the food industry, it’s used as a glazing agent for fruits and candies. In pharmaceuticals, shellac is used to coat tablets, offering moisture protection and enteric-release capabilities. Meanwhile, in wood finishing, shellac enhances the natural grain and color of wood, providing a traditional finish that’s both durable and beautiful.
What sets shellac apart from synthetic alternatives is its environmental profile. Shellac is biodegradable, renewable, and harvested without harming the host trees or surrounding ecosystem. As more industries move toward sustainable materials, shellac is seeing a resurgence in demand globally.
Whether you’re a manufacturer looking for a clean-label coating, an artisan seeking a natural finish, or a business exploring eco-friendly solutions, shellac remains a trusted, multi-use material that bridges the gap between tradition and modern innovation.
