Aseptic brick pack

A standard aseptic brick pack typically consists of six layers including polyethylene (PE), paperboard, and aluminum foil. The aluminum foil layer is critical as it provides a barrier against light and oxygen, while the high-grade paperboard provides mechanical strength and stability. When sourcing, ensure the PE layers are food-grade and the total structure supports a shelf life of 6 to 12 months without refrigeration.

Suppliers must adhere to strict food safety regulations. Key certifications include FDA (U.S. Food and Drug Administration) or EC 1935/2004 (EU) for food contact materials. Additionally, look for FSC (Forest Stewardship Council) certification to ensure the paperboard is sustainably sourced, and ISO 22000 or FSSC 22000 for food safety management systems.

Aseptic bricks are often designed for specific filling lines (e.g., TBA/19 or TBA/22 types). You must verify the creasing lines, hole punching (for straws/caps), and roll dimensions with the supplier. Request a technical drawing to confirm the eye-mark positioning for sensor detection during the high-speed filling process to prevent machine downtime.

For high-acid products like fruit juices, the inner PE layer must be resistant to fruit acids. For dairy products, the barrier against UV light must be absolute to prevent vitamin degradation and off-flavors. Ensure the supplier uses non-solvent inks for printing to avoid migration of chemicals into the liquid content.

The biggest risks are moisture damage during sea transit and core deformation. If the paper rolls absorb humidity, they will swell and become unusable in automated filling lines. Ensure the supplier uses heavy-duty palletizing, vacuum shrink-wrapping, and desiccant bags inside the container.

Custom printing usually requires a Minimum Order Quantity (MOQ) of at least 100,000 to 300,000 packs due to the complex rotogravure printing setup. Negotiate for plate fee waivers on repeat orders and ask for a tiered pricing structure where the unit price drops significantly as volume increases. For long-term contracts, link pricing to global paper pulp and aluminum price indices.

Aseptic packaging is heavy and sensitive to pressure. Specify 'Do Not Double Stack' for pallets to prevent crushing the bottom rolls. For shipping to distant markets, choose FOB (Free On Board) terms if you have a reliable freight forwarder who understands container selection (ensuring no holes or leaks that could lead to moisture ingress).

Request a factory audit report or a live video inspection of their clean-room production environment. High-quality suppliers on Made-in-China.com often have Audited Supplier status. Ask for COA (Certificate of Analysis) for every batch and perform a bursting strength test and layer adhesion test on samples before authorizing mass production.
