Looking for a biodegradable carrier bags wholesale supplier in China? The quick answer: head to major wholesale markets in Yiwu or Guangzhou, where stalls offer material samples, bulk pricing, and spot-check options. For example, at Soudangkou, you can directly compare PLA and PBAT blends under natural light.
Key Factors When Choosing a Supplier
Material: PLA vs. PBAT vs. Starch Blends
Biodegradable carrier bags typically use PLA (polylactic acid), PBAT, or starch-based blends. PLA feels stiffer and works best for lightweight loads; PBAT offers more flexibility. Always ask for a material data sheet and test a sample under warm water to check degradation claims.
Thickness & Durability
Common thicknesses range from 20 to 50 microns. Thicker bags (40-50 microns) handle heavier items but degrade slower. Check the stitching on handles – double-stitched seams indicate better quality in bulk orders.
Wholesale Market Stall Tips
In physical markets, touch the bags. Run your hand across the surface – a smooth, uniform texture signals good extrusion quality. Inspect the bottom seal: it should be flat and bubble-free. Ask the stall owner for a “spot lot” (少量现货) to verify color consistency across batches.
Most stalls offer tiered pricing: orders of 500-1,000 pieces yield a 10-15% discount compared to single-piece retail. Negotiate on shipping and ask if they can mix bag sizes in one container.
