Raschel bags

When selecting Raschel bags, the most critical factor is the mesh density and tensile strength. For heavy produce like potatoes or onions, ensure the bag has a reinforced base and mouth to prevent tearing during automated filling. You should specify the weight per bag (grams) rather than just dimensions, as this indicates the density of the polyethylene (PE) or polypropylene (PP) threads. Additionally, verify that the bags include a high-quality drawstring (usually made of PP) that is securely integrated into the weave to facilitate easy tying.

Since Raschel bags are primarily used for food packaging, they must be BPA-free and made from 100% virgin food-grade materials. Request FDA (USA) or EC 1935/2004 (EU) compliance certificates from the supplier. It is also vital to confirm that the dyes and colorants used in the mesh are non-toxic and lead-free, especially if the bags will be in direct contact with edible produce.

Raschel bags are often exposed to sunlight during transport and outdoor storage. Without UV stabilizers (typically 1% to 3% UV additive), the plastic mesh will become brittle and break within weeks. For cross-border buyers, always specify the UV resistance rating (e.g., 200-300 KLY) to ensure the bags maintain their structural integrity throughout the entire supply chain and shelf life.

Yes, for B2B buyers, customization is key. You can request printed central labels (bands) made of PE film that are sewn onto the mesh for branding and barcodes. If you use automatic packing machines, you must specify that the bags be delivered 'on rolls' (continuous) rather than 'in bundles' (individual) to ensure compatibility with high-speed filling equipment.

The primary risk is material substitution, where suppliers mix recycled plastic with virgin resin to lower costs, resulting in bags that break under pressure. To mitigate this, use Made-in-China.com's Secured Trading services and insist on a pre-shipment load test. Another risk is quantity discrepancies; since these are lightweight items, always verify the net weight of the total shipment against the theoretical weight per unit to ensure you aren't being short-changed.

Pricing for Raschel bags is highly sensitive to global polymer resin prices. It is wise to negotiate a formula-based pricing model linked to market indices if you are placing recurring large orders. For MOQs, while standard containers (20GP/40HQ) offer the best freight-per-unit cost, many top-tier suppliers on Made-in-China.com will accept smaller trial orders if you choose standard colors (like red, orange, or yellow) that are already in production.

Raschel bags are highly compressible. Ensure the supplier uses high-pressure hydraulic baling presses to maximize the number of units per container. This can reduce your landed cost by up to 20%. When shipping to regions with strict customs, ensure the Country of Origin (COO) is clearly marked on every bale to avoid clearance delays and potential fines.

Prioritize suppliers who are 'Audited Suppliers' on Made-in-China.com, as their production facilities and business licenses have been verified by third-party agencies like SGS or Intertek. Request a video audit of their weaving workshop to confirm they have the capacity to handle your volume and check for ISO 9001 certification to ensure consistent quality management.
