Onion packing bags manufacturers

Onions require high breathability to prevent rot and mold. You should prioritize Lenomesh (L-mesh) bags or Raschel mesh bags made from High-Density Polyethylene (HDPE) or Polypropylene (PP). These materials offer the necessary tensile strength to hold heavy loads (typically 5kg to 50kg) while ensuring maximum airflow. For premium retail packaging, tubular mesh rolls are preferred for automated packing machines.

Focus on the GSM (Grams per Square Meter), which determines the bag's thickness and durability; a higher GSM is essential for 25kg+ capacities. Ensure the UV stabilization treatment is included if the bags will be stored in sunlight, as untreated plastic degrades quickly. Additionally, check the breaking strength of the drawstring and the seam reinforcement (overlock stitching) to prevent bottom bursts during transport.

Since onions are food items, the bags must be food-grade and free from toxic dyes or heavy metals. Request SGS or Intertek test reports confirming compliance with FDA (US) or EC 1935/2004 (EU) regulations. If you are targeting eco-conscious markets, look for suppliers providing reusable or recyclable certifications and ensure the inks used for branded labels are non-toxic and lead-free.

The most effective way to reduce costs is through volume-based scaling; ordering in Full Container Loads (FCL) can reduce unit prices by 20-30% compared to LCL. Negotiate based on raw material index pricing (PP/PE market rates). Additionally, choosing standard sizes (e.g., 50x80cm for 25kg) is cheaper than custom dimensions due to mass production efficiencies at the factory level.

The primary risk is weight deviation, where the delivered GSM is lower than the sample, leading to bag breakage. To mitigate this, specify the exact weight per bag in the contract and hire a third-party inspection service to perform a 'drop test' and 'weighing test' before the balance payment is made.

When using Made-in-China.com, look for Audited Suppliers with high 'Trust Points.' Negotiate by requesting a tiered pricing structure and ask for free pre-production samples. Emphasize long-term cooperation to secure better payment terms, such as a 30% deposit and 70% against the Bill of Lading (B/L) copy.

Mesh bags are lightweight but bulky. Ensure the supplier uses high-pressure hydraulic baling presses to compress the bags into tight bales; this maximizes container utilization and lowers the freight cost per unit. Always clarify the Incoterms (FOB is recommended for better control over shipping) and ensure the packaging is wrapped in waterproof PE film to prevent moisture damage during sea transit.

Always conduct transactions through secure payment channels and avoid direct transfers to private accounts. Utilize the Secured Trading Service on platforms like Made-in-China.com to protect your funds until the shipping documents are verified. Ensure all specifications, including color tolerance and size margins (±1-2cm), are clearly documented in the Proforma Invoice (PI).
