Foods packaging

When sourcing food packaging, the most critical factor is ensuring the materials are food-grade and free from contaminants. You must verify that the supplier complies with FDA (U.S. Food and Drug Administration) regulations for the North American market or EC 1935/2004 and EU 10/2011 for the European market. Additionally, look for ISO 22000 or BRCGS (British Retail Consortium Global Standard) certifications, which guarantee a robust food safety management system throughout the manufacturing process.

Material selection depends on the barrier properties required. For products sensitive to oxygen and moisture (like coffee or snacks), prioritize high-barrier films such as AL (Aluminum) or VMPET (Metallized Polyester). For microwaveable meals, ensure the material is PP (Polypropylene), which has a high melting point. If sustainability is a brand priority, consider PLA (Polylactic Acid) or recyclable PE (Polyethylene) structures, but always verify their oxygen transmission rate (OTR) to ensure they don't compromise food freshness.

If you use automated filling machines, you must specify the coefficient of friction (COF) to ensure the film slides smoothly through the machine. Confirm the heat-seal strength and sealing temperature range to prevent leaks. For roll stock, provide the supplier with the exact roll direction, core diameter, and maximum outer diameter to ensure compatibility with your specific machinery.

Ensure the supplier uses non-toxic, food-grade inks (such as soy-based or water-based inks) that comply with the Swiss Ordinance or Nestlé Guidance Note on packaging inks. Request a migration test report to ensure that ink components do not leach through the substrate into the food. For branding, ask for Pantone color matching and a digital or physical proof to verify print registration and color accuracy before mass production.

Always conduct a Pre-Shipment Inspection (PSI) through a third-party agency like SGS or Intertek. Specifically, request a smell test (to detect residual solvents) and a leakage test (such as a vacuum chamber test). Using Made-in-China.com's Secured Trading Service can also protect your payment until the quality is verified against your initial specifications.

Focus on Total Cost of Ownership (TCO) rather than just the unit price. Negotiate for plate-making fee waivers on large recurring orders and ask for a tiered pricing structure based on volume (e.g., 50k, 100k, and 500k units). Ensure the contract includes a quality guarantee period (typically 12 months) as packaging materials can degrade if stored in improper humidity or temperature conditions.

Food packaging is often lightweight but high-volume, making sea freight the most economical choice. Ensure the supplier uses heavy-duty corrugated outer cartons and plastic pallets with shrink wrap to prevent moisture ingress and dust contamination during transit. For long-distance shipping, request desiccants inside the containers to manage 'container rain' caused by temperature fluctuations.

Stay informed about anti-dumping duties on specific materials like aluminum foil or certain plastic films from specific regions. Additionally, many countries are implementing Single-Use Plastic (SUP) bans or Plastic Taxes. Work with your supplier to ensure the HS Code (typically Chapter 39 for plastics or 48 for paper) is correctly declared to avoid customs delays and ensure you are paying the correct tariff rates.
