100% Corn Starch-Based Compostable Poly Bags — Approved by the Central Environmental Authority of Sri Lanka
The packaging industry is one of the largest contributors to plastic pollution globally — and Sri Lanka's businesses, retailers and manufacturers are increasingly being held accountable by international buyers, local regulators and environmentally conscious consumers for the packaging choices they make. PolyCreations' biodegradable bags offer a credible, certified and commercially viable answer to that pressure.
Manufactured from 100% corn starch-based polymers containing zero polyethylene or non-biodegradable substances, our biodegradable bags completely decompose into the soil without leaving harmful residues, microplastics or toxic by-products. They are approved by the Central Environmental Authority of Sri Lanka, meet international compostability standards and are available for both local and international markets across the textile, food, construction and any industry with packaging needs — making PolyCreations one of the very few manufacturers in Sri Lanka capable of supplying a genuinely certified compostable packaging solution at commercial scale.
Product Overview
PolyCreations' biodegradable bags are manufactured from polylactic acid (PLA) derived from corn starch — a renewable, plant-based resource that produces a polymer material with physical and functional properties comparable to conventional polyethylene, but with a fundamentally different end-of-life outcome.
Key Features
100% Corn Starch-Based Construction
Manufactured from polylactic acid derived from corn starch — a fully renewable plant-based resource. Contains zero polyethylene, zero petroleum-based polymers and zero non-biodegradable substances of any kind.
Complete Decomposition — No Microplastics
Unlike oxo-degradable bags that fragment into microplastics, our corn starch-based bags decompose completely into water, carbon dioxide and organic biomass through biological activity — leaving no harmful residue in the soil or water systems.
CEA Approved
Approved by the Central Environmental Authority of Sri Lanka — providing regulatory credibility for businesses operating under local environmental compliance requirements and supplying to international buyers with sustainability mandates.
Lower Carbon Footprint
Corn starch-based PLA production emits significantly less carbon dioxide than conventional petroleum-based plastic manufacturing — supporting the carbon reduction commitments of brands, retailers and supply chains with ESG reporting obligations.
Fully Recyclable and Reusable
The bags can be used multiple times before composting — and are fully recyclable, supporting circular economy principles and reducing the total volume of packaging material required.
Commercially Functional Performance
Despite their natural composition, our biodegradable bags deliver comparable tensile strength, moisture resistance and handling performance to conventional poly bags — maintaining the practical requirements of retail, food service, garment and industrial packaging applications.
Who It's For
