Know what the specification says
The published Kobags specifications identify non-woven PP and a GSM value. PP means polypropylene. GSM describes mass per square metre; it does not by itself establish load capacity or finished-bag durability.
Ask separately about recycled content
Polypropylene can be described by its material type without implying any recycled percentage. Ask for a product-specific composition declaration if recycled content is important to your purchase.
Check local recycling acceptance
The destination, collection system and finished bag all matter. Do not assume a bag will be accepted locally because its material can be recycled in some settings. Review printing and other components as part of the question.
