Tetra pak paper

When sourcing aseptic packaging material, you must verify the multi-layer structure, typically consisting of 75% paperboard, 20% polyethylene (PE), and 5% aluminum foil. Ensure the paperboard provides mechanical strength, the aluminum foil acts as a barrier against light and oxygen, and the PE layers ensure liquid-tight sealing. For high-speed filling lines, specify the GSM (grams per square meter) and stiffness to prevent machine jamming.

Since this product is in direct contact with food, it must comply with FDA (U.S. Food and Drug Administration) or EU Regulation No 10/2011 regarding plastic materials intended to come into contact with food. Additionally, look for FSC (Forest Stewardship Council) certification to ensure the wood pulp is sourced from sustainably managed forests, which is a critical requirement for most global retailers today.

Request the Oxygen Transmission Rate (OTR) and Water Vapor Transmission Rate (WVTR) test reports. High-quality aseptic paper should enable a shelf life of 6 to 12 months without refrigeration. You should also confirm the integrity of the longitudinal and transverse seals through burst tests to ensure the packaging remains sterile during long-distance logistics.

Top-tier suppliers on Made-in-China.com should offer Flexographic or Gravure printing with up to 8 colors using food-grade water-based inks. Ensure the supplier can provide different opening solutions, such as perforated V-cuts, straw holes, or plastic screw caps (HeliCap), and can match the specific creasing patterns required by your filling machine model (e.g., TBA/19, A3/Flex).

Incompatibility is a major risk. Always request a trial roll (sample) to run on your specific filling equipment before placing a bulk order. Verify the inner core diameter and outer roll diameter specifications. Professional suppliers on Made-in-China.com often provide technical engineers to consult on machine parameters to ensure the material's heat-sealing temperature matches your line speed.

Aseptic paper is sensitive to moisture and physical impact. Ensure the contract specifies seaworthy packaging, including heavy-duty pallets, moisture-proof plastic wrapping, and edge protectors. During transit, use reefer containers or dry containers with desiccants if crossing high-humidity zones. Upon arrival, store the rolls in a climate-controlled warehouse with a temperature of 15-25°C and humidity of 40-60%.

Given that paper pulp and aluminum prices fluctuate, consider a formula-based pricing model linked to global commodity indices. For transaction security, use Escrow services or Letter of Credit (L/C) for the first few shipments. On Made-in-China.com, prioritize Audited Suppliers who offer Trade Assurance to protect your payment until the goods are verified by a third-party inspector like SGS or Intertek.

Be aware of Anti-Dumping Duties (ADD) that some regions (like the EU or India) may impose on specific coated paper products from certain origins. Always check the HS Code (typically 4811.90) against your country's latest tariff schedule. Ensure the supplier provides a Certificate of Origin (CO) to benefit from any existing Free Trade Agreements (FTAs) that could reduce your import duties.
