In high-quality B2B Offset packaging manufacturing, the durability of corrugated cardboard sheets (cardboard blanks) relies entirely on raw paperboard origin and physical metrics. Any inconsistency from upstream mills leads to creases tearing, flutes flattening, or low burst test results. To assure client packaging performance, Chau Thai Son Printing and Packaging Joint Stock Company has established direct partnerships with global paperboard leaders, including Oji Paper (Japan), Vina Kraft (Thailand), and Hansol Paper (South Korea).
1. Premium Kraft Paperboard from Oji and Vina Kraft
Kraft liners forming the outer and inner walls of corrugated boxes determine puncture limits and Edge Crush Test (ECT) ratings:
-
Oji Kraft Liners (Japan): World-renowned for long-fiber strength, smooth surface finish, and low moisture absorption—optimal for protecting electronic components in 3-ply and 5-ply boxes.
-
Vina Kraft (Thailand): The leading supplier of heavy-duty corrugating medium. Utilizing Vina Kraft reels on BHS and Hsieh Hsu lines at 400m/min yields tightly bonded flutes with high stack capacity.
2. High-Aesthetic Duplex and Couche Boards from Hansol
For laminated boxes requiring detailed Offset printing and high aesthetics, Chau Thai Son uses Hansol (South Korea) boards:
-
Optimal Brightness and Ink Adhesion: Hansol duplex boards allow our Roland R706 6-color Offset press to reproduce Pantone hues, small fonts, and sharp logos to match 3D drawings.
-
Mechanical Thickness Consistency: Boards resist curling and warping under GSZ-1020 film laminators, outputting flat sheets for precise die-cutting on our 6 automatic presses.
3. 3D Design Consulting and Free Physical Mockups
Sourcing certified raw materials allows Chau Thai Son to deliver packaging solutions that reduce customer costs by 15% - 20%:
-
Complimentary Mockups: We prepare physical Mockup samples using genuine paperboard free of charge for clients to run bursting and ECT compression testing in our laboratory.
-
Export Palletization: Finished items are stacked on Pine or Acacia wood pallets, reinforced with thick paper V-board corner protectors, and stretch-wrapped for logistics dispatch.
