Corrugated Materials, Flutes & Finishes
Deep technical specifications on board weights, fluting calipers, burst testing, and sustainable water-based coatings.
Corrugated Flute Comparison: E-Flute vs. B-Flute
#flutesFluting profile governs both the printing resolution of your outer artwork and the compression defense of your shipped products.
E-Flute (1/16" / 1.6mm)
Featuring 90 flutes per linear foot, E-Flute delivers the smoothest possible print canvas with virtually no washboarding pattern. It is the gold standard for high-end direct-to-consumer presentation, cosmetics, jewelry, and retail packaging.
B-Flute (1/8" / 3.2mm)
Featuring 47 flutes per linear foot, B-Flute provides double the cushioning and vertical stacking strength. Recommended for fragile items, glass bottles, hardware, footwear, and payloads exceeding 10–15 lbs.
Paper Board Substrates: Natural Kraft vs. Bleached White
#boardsThe base substrate controls background contrast, organic texture, and environmental messaging.
100% Recycled Natural Kraft
Raw, organic brown paperboard highlighting natural wood fibers and sustainability. Perfect for minimalist black typography, single-color flexo prints, and eco-conscious lifestyle brands.
Bleached White Top Liner
Bright white coated face sheet that delivers true-to-life Pantone color reproduction, brilliant photography, and maximum contrast for full-coverage CMYK artwork.
Printing Capabilities: Flexographic & High-Definition Digital
#printingDepending on your production volume, artwork intricacy, and brand color standards, we deploy precision high-speed flexo presses and G7-certified digital inkjet lines.
Flexographic Printing (Rotary Plates)
Industrial rotary polymer plates apply water-based eco inks at rapid line speeds. Ideal for high-volume wholesale runs (1,000+ units) featuring bold brand logos, spot PMS colors, and exterior carton graphics with low per-unit ink costs.
High-Definition Digital CMYK (Plate-Free)
Direct-to-corrugated inkjet printing eliminates physical print plate tooling fees. Enables multi-version graphic variations, photographic gradients, and full double-sided interior flood coats at 500-unit minimums.
Surface Varnishes & Premium Finishes
#coatingsMatte Soft-Touch
Smooth, velvety non-glare surface that feels luxurious in the customer's hands and resists fingerprints.
Gloss Aqueous (AQ)
Protective water-based seal that makes colors pop while defending against scuffs and postal conveyor abrasion.
Spot UV & Foil Stamping
High-gloss raised accents on logos and headings paired with metallic gold or silver foil stamping for retail luxury.
Board Strength & Compression Ratings: ECT-32 vs. ECT-44
#strengthCorrugated strength is rated through TAPPI standards: Edge Crush Test (ECT) for pallet stacking compression, and Mullen Burst Test (lbs/sq in) for puncture defense.
ECT-32 Single Wall Rating
Standard for parcel shipping under 10 lbs. Provides 32 lbs per linear inch of edge crush resistance, ideal for standard e-commerce deliveries, subscription boxes, and lightweight goods.
ECT-44 Heavy-Duty Single Wall
Engineered for heavier parcel shipments (15 to 40 lbs) and master cartons. Delivers roughly 38% greater stacking compression to prevent bottom-tier box collapse on palletized freight.
