Compostable vs Plastic Pouches: True Cost & Shelf Life
Green claims must survive real shelf-life testing.
Direct answer
Compostable pouches cost more, have lower moisture and oxygen barrier, and usually offer shorter shelf life than conventional plastic laminates. They are right for dry products with short shelf life and strong sustainability positioning; high-barrier needs and long shelf life still favor conventional films or recyclable mono-material structures.

FAQ
Are compostable pouches actually better for the environment?
They reduce plastic waste when composted correctly, but require industrial composting infrastructure. Confirm your market's disposal routes before switching.
Why is my shelf life shorter with compostable film?
Compostable films typically have lower barrier than metallized plastic, allowing more moisture and oxygen through over time.
Can compostable pouches hold coffee?
Some can, but shelf life will be shorter than with high-barrier plastic. A shelf-life test is strongly recommended first.
Are compostable pouches more expensive?
Yes, material and converting costs are higher, so unit price is typically above conventional laminates.
