The Science Behind Compostable Bags: What Are They Made Of?
Introduction
Compostable bags look like plastic but are powered by the latest in green chemistry. Let’s decode what makes them both durable and earth-friendly.
The Core Materials
- PLA (Polylactic Acid): It is derived from corn starch; it is strong and clear.
- PBAT (Polybutylene Adipate Terephthalate) provides flexibility and compostability.
- Corn Starch & Plant Oils: Provide the biodegradable base.
These materials break down through microbial activity under composting conditions into CO₂, water, and organic matter without leaving toxins.
Eco-Certified Durability
Every product at Biometa Polypack undergoes CPCB-approved lab testing to ensure:
- Compostable within 180 days
- Non-toxicity
- Mechanical strength and usability
Conclusion
Science and sustainability go hand in glove. Compostable bags stand for innovation rooted in nature, proof that technology need not harm but heal.
