Tomato paste bags

Tomato paste is highly acidic and sensitive to oxidation, so you must prioritize multi-layer laminate structures. The most common configuration is PET/AL/NY/PE or PET/VMPET/PE. The Aluminum foil (AL) layer is critical as it provides a 100% barrier against light, oxygen, and moisture, which is essential for maintaining the paste's color and shelf life. For aseptic filling, ensure the bags are compatible with gamma irradiation sterilization.

Suppliers must provide FDA (U.S. Food and Drug Administration) or EU Food Contact (EC No 1935/2004) certification. Additionally, look for ISO 22000 or BRC (British Retail Consortium) global standards for food safety. Ensure the manufacturer provides a Declaration of Compliance (DoC) stating that the migration levels of chemicals from the plastic into the tomato paste are within legal limits.

The choice depends on the end-use scenario. For industrial B2B processing, choose Aseptic BIB (typically 5L to 220L) with high-barrier valves to prevent contamination during dispensing. For B2C retail, Stand-up Pouches (Doypacks) with spouts are preferred for consumer convenience. Ensure the spout and cap design features a tamper-evident seal to guarantee product integrity during transit.

To prevent 'flex cracking' or bursting, the bags must have high puncture resistance and strong heat-seal strength. Request burst pressure test reports and drop test data. For large volume bags (like 220L), the outer liner should be reinforced to withstand the hydraulic pressure of the paste during sea freight vibrations.

Always request a pre-shipment sample and conduct a third-party lab test (such as SGS or Intertek) to verify food-grade safety. On Made-in-China.com, prioritize Audited Suppliers whose production facilities have been physically verified. Use secured payment terms that allow for inspection before the final balance is released.

Focus on Total Cost of Ownership (TCO) rather than just the unit price. Negotiate based on volume tiers; for example, increasing an order from 10,000 to 50,000 units can often reduce the price by 15-25%. Ask the supplier to include 1-2% extra units free of charge to cover potential damage during the filling process at your facility.

Empty bags are lightweight but bulky. Use vacuum packaging for the empty bags themselves to reduce shipping volume and costs. Ensure the pallets are plastic-wrapped and corner-protected to prevent moisture ingress or dust contamination during sea freight. Confirm the HS Code (usually 392321 or 392329) with your customs broker to avoid tariff misclassification.

Utilize the Trade Resources and Audit Reports available on Made-in-China.com to check the supplier's business license and export history. Avoid direct wire transfers to private accounts; always use corporate bank accounts verified by the platform. For large contracts, specify a quality claim period of at least 90 days after the goods arrive at your port.
