At 105, we offer a full range of packaging flute types, balancing protection, cost, and sustainability.

Measuring Cardboard Thickness

Cardboard thickness is measured by GSM, points (PT), flute type, and wall type. Flute types vary in thickness and are suited for different uses:

At 105, our expertise ensures your packaging provides optimal protection while minimizing costs.

Types of Cardboard Flutes and Thicknesses

Flute types define a box’s strength and performance. Here’s a quick overview:

• E-flute (1.5 mm): Sleek, ideal for retail, pizza boxes, and small packages.
• B-flute (3 mm): Durable, used for custom mailers and shipping boxes.
• C-flute (4 mm): Sturdy, for general-purpose or heavy items.

At 105, we customize flute types for your exact needs, ensuring robust and cost-effective solutions.

Why Cardboard Thickness Matters

Proper cardboard thickness enhances:

• Product Protection: Prevents damage during shipping.
• Structural Integrity: Ensures durability in transit/storage.
• Printing Quality: Supports better branding visuals.
• Cost Efficiency: Balances material and shipping costs.
• Sustainability: Reduces waste and environmental impact.

We optimize thickness to protect products and save on shipping, tailored to your specific requirements.

Choosing the Right Thickness

Factors to consider when selecting cardboard thickness:

• Product weight and fragility: Heavier, fragile items need thicker cardboard.
• Shipping method and distance: Long distances may require sturdier options.
• Stacking needs: Ensure boxes maintain shape during storage or transit.
• Printing and branding: Match thickness to design needs.
• Cost: Balance durability with material expense.

At 105, we help you find the perfect solution, from sleek E-flute pizza boxes to robust B-flute mailers.

Cardboard Packaging Material Types

Cardboard packaging isn't just about thickness—it also involves material composition and construction. Here are the common types:

• Corrugated Cardboard: A combination of flat liners and fluted layers. Commonly used for shipping due to its strength and cushioning.
• Single-Face Board: Consists of one flat liner glued to one fluted layer. Lightweight and flexible, it’s ideal for protective wrapping and inserts rather than full boxes.
• Single-Wall Board: Features one fluted layer sandwiched between two flat liners. It’s versatile and commonly used for retail packaging, mailers, and shipping boxes.

• Double-Wall Board: Two fluted layers and three flat liners provide extra strength and durability. Perfect for heavy or fragile items requiring robust shipping solutions.
• Solid Board: A single, thick sheet, often used for smaller boxes or luxury packaging. Great for high-quality printing and premium aesthetics.
• Recycled Cardboard: Eco-friendly, made from post-consumer materials. Combines sustainability benefits with adequate strength.
• Kraft Cardboard: Unbleached with a natural brown appearance. Strong and ideal for eco-conscious branding.
• White Cardboard: Bleached for a clean, premium look. Often used for retail and presentation packaging.
