Corrugated Boxes

Corrugated boxes are essential in packaging, known for their durability, strength, and versatility. Here's a breakdown of the key aspects of corrugated boxes:

Corrugated boxes are made from corrugated fiberboard, which consists of a fluted corrugated sheet sandwiched between flat linerboards. This structure provides cushioning and strength, making it ideal for shipping and protecting products.

• Flutes: The wavy middle layer that gives the box its strength and shock absorption.
• Linerboards: The flat outer layers that enclose the fluted layer. These can be made from kraft paper or recycled materials.

Flutes come in various sizes, affecting the box's strength and cushioning properties:

• A-Flute: Thick and strong, good for cushioning and stacking.
• B-Flute: Thin and stiff, offers good printing surface and puncture resistance.
• C-Flute: Most common, a balance of strength and cushioning.
• E-Flute: Very thin, ideal for small, lightweight packaging.
• F-Flute: Extra thin, used for high-quality printing and small packages.

• Single-Wall: One layer of fluting between two linerboards. Common for everyday shipping.
• Double-Wall: Two layers of fluting and three linerboards, used for heavier items or long-distance shipping.
• Triple-Wall: Three layers of fluting, offering the highest strength for extremely heavy or fragile items.

• Edge Crush Test (ECT): Measures the box's stacking strength (how much weight it can withstand before crushing).
• Bursting Test (Mullen Test): Measures resistance to puncturing and pressure.

• Regular Slotted Container (RSC): The most common style, with flaps of the same length that meet at the center when closed.
• Full Overlap (FOL): Flaps overlap fully, providing extra strength.
• Half-Slotted Container (HSC): Has a bottom flap and an open top, often used for removable lids.

Corrugated boxes are eco-friendly, being 100% recyclable and often made from recycled materials. They are also biodegradable.

Used in shipping, retail packaging, storage, and even marketing displays. Corrugated boxes can be customized in size, shape, and print design to suit various needs.

• Protection: Excellent cushioning and impact resistance.
• Cost-Effective: Affordable and efficient for mass production.
• Sustainable: Made from renewable resources and widely recyclable.
• Versatile: Suitable for a wide range of products, from electronics to food.
