Box Style Types
Corrugated boxes come in several standard styles, each designed for specific applications and product types.
- •RSC (Regular Slotted Container): Most common, four flaps meet at center
- •FOL (Full Overlap): Extra flap coverage for heavy items
- •HSC (Half Slotted Container): Open-top boxes for displays or machines
- •Telescope: Two-piece with separate lid, stackable
- •Die-Cut: Custom shapes for unique products
Flute Types Explained
The flute is the wavy middle layer of corrugated board. Different flute sizes provide different properties.
- •A-Flute (5mm): Best cushioning, good stacking strength
- •B-Flute (3mm): Good puncture resistance, smooth printing surface
- •C-Flute (4mm): Most common, balanced properties
- •E-Flute (1.5mm): Thin, excellent print quality, retail packaging
- •F-Flute (0.75mm): Very thin, superior printing, small packaging
Wall Construction
Single, double, and triple wall constructions provide increasing strength and protection levels.
- •Single Wall: One flute layer, standard shipping applications
- •Double Wall: Two flute layers, heavy items up to 80 lbs
- •Triple Wall: Three flute layers, industrial applications to 300+ lbs
- •Wall selection depends on weight and fragility of contents
RSC Boxes (Regular Slotted Container)
The RSC is the most economical and widely used box style. Four flaps on top and bottom fold to meet at center.
- •Economical due to efficient material use
- •Easy to assemble and seal
- •Works for most shipping applications
- •Available in thousands of standard sizes
FOL and Overlap Boxes
Full overlap boxes provide extra bottom protection and stacking strength, ideal for heavy contents.
- •Flaps overlap completely rather than meeting at center
- •Provides double thickness at bottom for strength
- •Better puncture resistance
- •Recommended for items over 50 lbs
Die-Cut and Custom Boxes
Die-cut boxes are custom manufactured for specific product shapes, providing optimal fit and presentation.
- •Custom shapes for unique products
- •Can include built-in inserts and compartments
- •Excellent for retail presentation
- •Higher tooling cost but better product protection
