For dry goods such as canned foods, instant noodles, dried agricultural products, metal parts, or garments, packaging must satisfy requirements for lightweight properties, moisture control, and budget optimization. Tien Thanh Packaging Joint Stock Company (Tien Thanh A&E) delivers the ultimate solution with our high-quality 3-ply corrugated boxes, partnering with B2B manufacturing enterprises.

1. Physical Structure and Moisture Absorption of 3-Ply Carton Boxes

A 3-ply corrugated box consists of 2 flat paper liners and 1 sinusoidal fluted layer in the middle (utilizing B, C, or E flute configurations depending on thickness requirements):

• Elastic Cushioning Structure: The middle flute layer acts as a shock absorber, dispersing light impact energy during transport handle.

• Natural Dehumidification: Paper possesses natural moisture-absorbing properties. The 3-ply boxes from Tien Thanh A&E capture excess airborne humidity inside the box, preserving dried foods or agricultural produce in dry conditions and preventing mold.

• Ultra-Lightweight: The 3-ply construction minimizes packaging weight, reducing long-distance shipping (Logistics) costs for businesses.

2. Technical Features and High-Quality Printability

The 3-ply corrugated boxes at Tien Thanh A&E comply with the strict quality controls of our smart factory:

• Optimal Bursting Strength: A paperboard weight ranging from 300 to 550 gsm guarantees a bursting strength of ≥ 8.0 kgf/cm² and robust edge crush test values, allowing multiple boxes to be stacked on pallets without collapsing.

• Smooth Surface for Printing: Processed through advanced flat-press machinery, the paper liners are optimized for our high-speed 7-color Flexo printing press (300 sheets/min), yielding crisp and uniform logo prints.

• Safe Organic Adhesives: Employs organic starch-based glue to bond the flutes, ensuring safety for indirect food packaging.

3. International Standards and Green Commitments

At our FSC-certified smart factory, Tien Thanh A&E commits to:

• 100% traceable, eco-friendly, and fully recyclable paper materials.

• Highly automated machinery integrated with Poka-Yoke sensors to eliminate dimensional defects, ensuring on-time delivery for global FDI partners.
