Traditional stickers and decals are typically made from PVC (polyvinyl chloride), a petrochemical plastic that harms the environment and human health. Its production contributes to pollution and health risks, it emits toxic gases during use, and it's difficult to recycle—often ending up in landfills or oceans.
The Invention
This patent introduces a sustainable, PVC-free alternative: a thin film made from natural biopolymers like agar (from red algae) and gelatine (from collagen), optionally combined with glycerine for flexibility. The resulting film can be used for stickers, decals, signage, and protective or decorative surfaces—just like PVC, but without the environmental damage.
What’s New
The unique breakthrough lies in developing a method to produce these biodegradable films at scale while achieving the same smooth finish, durability, and compatibility with existing sticker-making machines used for PVC. This includes plotters, printers, and cutters. The films can even stick to surfaces like glass using only moisture—no glue required.
Benefits
- Eco-friendly: Made from renewable, non-toxic, and compostable materials.
- Recyclable: Old decals can be dissolved in water, re-melted, and reused.
- Safe: No harmful emissions or residues, making it ideal for indoor and artistic use.
- Practical: Compatible with existing cutting and printing equipment.
- Versatile: Works for branding, signage, decoration, and more—just like PVC decals.
Broader Impact
This invention helps reduce plastic waste and reliance on petroleum. It offers a viable green alternative for industries like retail, architecture, and art. As environmental regulations tighten and sustainability becomes a brand priority, this material could play a key role in transforming how visuals are displayed in commercial and public spaces—without compromising performance or aesthetics.
