Description
Eco-friendly packaging uses biodegradable polymers and natural fibers to extend shelf life while reducing environmental impact.
Technical
Polylactic acid films provide a moisture‑vapor barrier of 1.5 × 10⁻⁹ g m⁻² s⁻¹ Pa⁻¹ at 25 °C/60 % RH, while vacuum sealing reduces internal O₂ to <1 % and preserves leafy greens for up to 14 days at 4 °C. Bio‑based polyethylene blends maintain tensile strength >30 MPa at 20 °C and lower carbon footprint by 18 %.
