Why Choose Corrugated
Custom Corrugated Packaging | Fluted Board for Shipping, Retail Display, and E-Commerce
Corrugated board consists of three layers -- an outer liner, a fluted medium, and an inner liner -- bonded together to create a rigid, lightweight structure with extraordinary compression resistance relative to its weight. The fluted medium's wave geometry distributes compressive forces across the flute arches rather than concentrating them at single points. This structural efficiency makes corrugated the dominant packaging material for product shipping and heavy retail display applications globally.
Flute Profiles and Applications
Corrugated is produced in multiple flute profiles. A-flute (4.7mm) provides maximum vertical compression resistance and cushioning for fragile and heavy product shipping. B-flute (3.2mm) provides balanced compression resistance and printability -- the most common specification for consumer product shipping. C-flute (3.6mm) is standard for most RSC shipping box applications and food service packaging. E-flute (1.2mm) has a fine, smooth profile approaching folding carton smoothness -- used for retail-quality print applications where both structure and high-quality printing are required.
ECT and Box Strength
Corrugated board strength is measured by the Edge Crush Test (ECT). Standard single-wall specifications: 32 ECT for parcel carrier shipping under 65 lbs, 44 ECT for heavier loads up to 100 lbs, and double-wall for industrial applications above 100 lbs.
Flute Selection for Application Performance
Corrugated flute selection is the most important structural specification decision. A-flute provides maximum cushioning for fragile products and heavy stacking loads. B-flute provides balanced compression resistance and printability -- the standard for consumer product and e-commerce shipping. C-flute is intermediate -- used for food service and larger-format shipping. E-flute provides a smooth printing surface approaching folding carton quality while maintaining corrugated structure -- used for retail-display and premium packaging where print quality is a priority alongside structural performance.
Single-Wall, Double-Wall, and Triple-Wall Construction
Single-wall corrugated covers standard shipping from 32 ECT to 44 ECT. Double-wall corrugated (7-8mm total) provides compression resistance exceeding 200 lbs for industrial freight, heavy product shipping, and high-stack warehouse storage. Triple-wall serves as a pallet alternative for very heavy industrial applications. The choice between construction types should be based on product weight, stacking configuration, and distribution channel requirements.

Corrugated Packaging in San Diego — FAQs
What is the difference between B-flute and E-flute corrugated?
B-flute (3.2mm) provides higher compression resistance and cushioning but more surface texture limiting print quality. E-flute (1.2mm) has a smoother surface enabling significantly better print quality but with lower compression resistance. E-flute is preferred when print quality is the priority; B-flute when maximum protection is needed.
What ECT rating do I need?
32 ECT single-wall is standard for parcel carrier shipping under 65 lbs. 44 ECT handles heavier products up to 100 lbs. Double-wall BC-flute is appropriate for products over 100 lbs or maximum stacking compression resistance.
Can corrugated be printed in full color?
Yes. Options include flexographic printing (up to 6 colors for high-volume programs), lithographic lamination (offset-printed litho sheet laminated to corrugated for near-folding-carton quality), and digital corrugated printing (CMYK at 100-unit minimums without plate costs).
Is corrugated packaging recyclable?
Yes. Corrugated is one of the most widely recycled packaging materials -- accepted in virtually all curbside and commercial recycling programs. Standard corrugated without excessive tape or plastic coating is universally accepted.
What is the minimum order for custom corrugated packaging?
Our minimum order is 100 units for custom corrugated packaging. Digital corrugated printing makes short-run branded corrugated economical at 100 units without flexographic plate costs.
