For packaging factories and businesses with large-scale internal packing operations, corrugated cardboard sheets (or cardboard blanks) are essential raw materials. The quality of cardboard sheets – including thickness, flatness, board adhesion, and bursting strength – directly decides the structural integrity of the finished corrugated boxes. Chau Thai Son Printing and Packaging Joint Stock Company proudly supplies high-quality corrugated cardboard sheets with diverse A, B, C, and E flutes generated from state-of-the-art high-speed corrugator lines.
1. Understanding Corrugated Flute Types and Applications
Each flute profile has distinct physical dimensions regarding height and number of flutes per meter, offering unique structural capabilities:
A Flute (Flute height ~4.7mm): Offers the best top-to-bottom stack strength. Ideal for manufacturing boxes containing heavy items requiring vertical warehouse stacking.
B Flute (Flute height ~2.5mm): Provides excellent puncture resistance and side-compression strength. Features a flatter surface than A flute, commonly used for fruit, food, and consumer component cartons.
C Flute (Flute height ~3.6mm): A well-rounded combination of A flute's stacking capability and B flute's puncture resistance. This is the most widely used flute type for general industrial shipping cartons.
E Flute (Flute height ~1.5mm): The thinnest flute profile, offering outstanding crush resistance and a very smooth printing surface. Best suited for high-quality litho-laminated offset boxes containing cosmetics, shoes, and retail consumer goods.
2. High-Speed Corrugator Lines - Guaranteeing Consistent Sheet Quality
The premium quality of Chau Thai Son's cardboard blanks is achieved through our synchronized BHS (Germany) and Hsieh Hsu corrugator line combination operating at speeds up to 400m/min:
Perfect Flatness: Automatic heat-controlled systems closely regulate raw paper roll moisture (sourced from Oji, Vina Kraft, and Hansol), preventing cardboard sheets from wrapping, delamination, or blistering.
High-Bonding Moisture-Resistant Adhesives: Specialized cornstarch glue ensures a strong bond between fluting mediums and flat liners, keeping the box structurally rigid even in damp warehouse settings.
Flexible Specifications: Producing 3-ply, 5-ply, and 7-ply cardboard sheets customized to your required dimensions to minimize paper trim waste during post-press processes.
3. Technical Consultations and Free Mockup Services at Chau Thai Son
Alongside raw material quality, professional service is our core commitment:
Free Structural Consulting: Chau Thai Son's engineering team analyzes your packing lines to recommend optimal flute combinations (e.g., BC, AB double-wall boards), protecting goods while reducing paper board costs by 15% - 20%.
