The short answer
Compostable bags can cost more because the job is stricter. The material, testing, certification, packaging and supply chain all have to line up.

And then the bag still has to behave in a kitchen. Nobody wants a principled puddle.

The claim has to be proved, not just printed.
What adds work
A compostable claim needs conditions. Home composting, commercial composting, soil and water are not the same setting. Good labels do not pretend they are.

Testing and certification cost money, but they also stop copywriters from wandering into fairy-tale territory.

Packaging matters too. If a product is trying to reduce plastic waste, wrapping it in more avoidable plastic would be a weird little plot twist.

How to judge value
Do not compare only on price per roll. Compare fit, strength, tie handles, certification scope and whether the bag suits your disposal route.
