Corrugated Box Flute Types

1. Single Face: Single face corrugated consists of one liner attached to one corrugated medium. It offers minimal protection and is primarily used for wrapping and cushioning fragile items.
2. Single Wall: Single wall corrugated has one liner attached to a corrugated medium, creating a standard cardboard box. It provides moderate strength and is commonly used for packaging various products.
3. Double Wall: Double wall corrugated consists of three layers – two liners and one corrugated medium. This type offers enhanced durability and is ideal for heavy or fragile items requiring extra protection during shipping.
4. Triple Wall: Triple wall corrugated is the strongest option, comprising three liners and two corrugated mediums. It provides maximum strength and is suitable for extremely heavy or large items, often used in industrial applications.
5. Micro Flute: Micro flute corrugated features tiny flutes that are closer together, creating a smooth surface. It is often used for retail packaging due to its printability and lightweight nature.
6. Mini Flute: Mini flute corrugated has smaller flutes than standard corrugated boxes, offering a balance between printability and strength. It is often used for point-of-purchase displays and packaging.
7. Macro Flute: Macro flute corrugated has larger flutes, making it suitable for heavy-duty packaging and palletizing due to its excellent stacking strength.
8. Honeycomb: Honeycomb board consists of a core structure resembling a honeycomb. It is exceptionally strong, lightweight, and eco-friendly, making it ideal for protecting delicate or high-value items during shipping.

Each corrugated box flute type serves specific packaging needs, with varying degrees of strength, durability, and printability, allowing businesses to choose the most suitable option for their products and shipping requirements.
