Buying Guide: Key Purchase Considerations
- Bin size and capacity: Match bag capacity to your bin’s volume to avoid overflows and frequent changes.
- Certifications: Look for BPI, OK compost HOME, and ASTM D6400 certifications to ensure compatibility with home composting or industrial facilities.
- Strength and thickness: Thicker liners (e.g., 0.63–0.71 mil) offer better puncture resistance for wet waste but can be less flexible. Balance durability with ease of use.
- Leak resistance and odor control: Sealing ability and leak-proof bottoms help minimize mess and odors between bag changes.
- Material origin and disposal: Plant-based, compostable materials reduce environmental impact but verify local composting capabilities and guidelines.
- Storage and shelf life: Store in a cool, dry place away from heat to maintain film strength and prevent premature degradation.
- Bag count and value: Consider the cost-per-bag and whether a larger roll or multi-pack best suits your household consumption.
- Compatibility with bin style: Some bags are optimized for specific bin shapes and opening diameters—measure your bin to ensure a proper fit.
- Return and warranty policies: Check for guarantees on compostability claims and packaging integrity.
- Environmental impact: Choose bags designed for home composting where feasible, and avoid bags that require industrial facilities not available locally.
