QUALITY ASSURANCE

Every Batch Tested For:

  • Purity and composition
  • Physical properties (density, moisture, melting point)
  • Strength and flexibility
  • Safety (heavy metals, toxicity, food safety)
  • Biodegradation verification

CERTIFICATIONS

Our Materials Meet:

  • ASTM D6400 (International Composability)
  • EN 13432 (European Standard)
  • FDA Food Contact Safe
  • BPA-Free & Non-Toxic

TECHNICAL SPECIFICATIONS

ENVIRONMENTAL RESPONSIBILITY

Our Raw Materials Are:

  • 100% plant-based (no petroleum)
  • Certified compostable
  • Non-toxic and BPA-free
  • Food-safe
  • 80%+ locally sourced in Bangladesh
  • Zero microplastics (complete biodegradation)

Impact:

  • 40% lower CO₂ than plastic production
  • Renewable resources only
  • Returns to the soil as nutrients

STORAGE & HANDLING

Proper Storage:

  • Cool, dry place (15-25°C)
  • Humidity <60%
  • Away from direct sunlight
  • Shelf life: 18-24 months

No degradation during storage—only biodegrades when disposed of properly.
