New Boxes

When Only New Will Do

We are passionate advocates for used packaging — but we also understand that certain applications demand virgin corrugated. Food-grade compliance, brand-printed exteriors, and exact-specification engineering all require new boxes. We supply them at competitive prices with fast turnaround.

When to Choose New Boxes

Food-Grade Requirements

Direct food contact demands virgin corrugated board that has never held other products. Our new food-grade boxes meet FDA and USDA requirements for primary and secondary food packaging.

Custom Branding

Your box is the first thing your customer sees. Custom-printed new boxes with your logo, colors, and messaging create a premium unboxing experience that used boxes cannot replicate.

Exact Specifications

When your product requires a precise internal dimension, specific flute profile, or engineered crush strength, a custom-manufactured new box ensures perfect fit and performance.

Regulatory Compliance

Certain industries — pharmaceuticals, medical devices, hazardous materials — mandate new, untouched packaging with documented chain-of-custody. We supply compliant options.

ECT Ratings Explained

The Edge Crush Test (ECT) measures how much top-to-bottom compressive force a box can withstand before buckling. A higher ECT number means stronger stacking performance. ECT has largely replaced the older Mullen Burst Test as the industry-standard metric for box strength.

Box Style Guide

Corrugated boxes come in many styles beyond the standard RSC. Each design serves specific functional and aesthetic purposes. Here is a comprehensive guide.

RSC (Regular Slotted Container)

The most common box style. All four flaps are the same length and meet at the center. Simple, economical, and versatile. Works for 80% of shipping applications. Available in every ECT rating and size.

Best for: General shipping, storage, e-commerce

Min order: 25 units (standard), 100 units (custom size)

HSC (Half Slotted Container)

Bottom flaps only — open top. Used with a separate lid for easy access or left open for display and pick-and-pack operations. Popular in warehousing and retail.

Best for: Warehouse bins, display packaging, easy-access storage

Min order: 50 units (standard), 250 units (custom size)

FOL (Full Overlap)

All flaps extend the full width of the box and overlap completely when closed. Creates a double-thick top and bottom for extreme stacking strength and moisture resistance. Heavier and more expensive than RSC.

Best for: Heavy items, long-distance freight, extreme stacking

Min order: 100 units (custom only)

Die-Cut Mailer

One-piece design that folds into a self-locking tuck-top box. Opens like a book for a premium unboxing experience. No tape required. Available with full-color printing for brand impact.

Best for: E-commerce DTC, subscription boxes, premium retail

Min order: 250 units (simple), 500 units (printed)

Telescoping Box

Two-piece design with a separate lid that slides over the base. Provides adjustable height and superior protection for flat or thin items. Excellent stacking performance.

Best for: Framed art, mirrors, flat electronics, documents

Min order: 100 units

Auto-Bottom Tray

Pre-glued bottom that pops open and locks into place without tape. Dramatically speeds up packing operations in high-volume environments. Top flaps fold closed normally.

Best for: High-speed fulfillment, food packaging, produce trays

Min order: 500 units

Five-Panel Wrap

A flat sheet that wraps around the product and tucks closed. Adjustable to different product thicknesses. Used for flat items like books, frames, and panels.

Best for: Books, picture frames, flat panels, mirrors

Min order: 100 units

Partition / Cell Box

An RSC or HSC with built-in corrugated dividers that create individual cells. Protects multiple items from contact damage. Die-cut partitions lock into the box walls for stability.

Best for: Bottles, jars, glassware, electronics components

Min order: 250 units (box + partition set)

Retail-Ready / Shelf-Ready

Shipping box that converts to a display with perforated tear-away lid and graphics. Goes from truck to shelf without repackaging. Reduces retailer labor costs and speeds up restocking.

Best for: Retail distribution, grocery, convenience stores

Min order: 1,000 units (printed)

Our engineers select the optimal board grade, flute profile, ECT rating, and box style for your product weight, fragility, and shipping conditions. We use TOPS (Total Optimized Packaging Solutions) software to model stacking performance and transit hazards before cutting a single die.

Graphic Design & Prepress

We create print-ready artwork from your brand guidelines, or design from scratch if needed. Our prepress team ensures color accuracy, proper bleed and registration, and corrugated-specific adjustments like dot gain compensation for flexographic printing.

Prototyping & Testing

Physical prototypes are produced on our sample-making table — typically within 2-3 business days. You receive actual-size samples to test fit, evaluate print quality, and run shipping trials. ISTA drop and compression testing available for validated designs.

Dieline Templates

We provide precise dieline templates (in AI, PDF, or DXF format) so your design team can create artwork that aligns perfectly with score lines, fold points, and print boundaries. Templates are free with any new box order.

Volume Discounts

The per-unit cost of new boxes drops significantly at higher quantities because setup and tooling costs are amortized across more units. Here is a general pricing framework — exact quotes depend on size, ECT, and printing.

Frequently Asked Questions

What ECT rating do I need for my product?

As a rule of thumb: 32 ECT for items under 20 lbs, 44 ECT for 20-50 lbs, 48 ECT for 50-80 lbs, and 51+ ECT for anything heavier. However, box size, stacking height, and shipping distance also matter. Tell us your product weight and how high you stack, and we will recommend the optimal rating.

Can you match my brand colors exactly?

Yes. We print using PMS (Pantone Matching System) spot colors, which ensures consistent, repeatable color across every production run. For litho-laminate printing, we use ICC color profiles calibrated to our presses. We provide press proofs for approval before full production.

What file formats do you accept for artwork?

We accept Adobe Illustrator (.ai), PDF, and EPS files with text converted to outlines and images at 300+ dpi. We provide dieline templates in your preferred format so your designer can place artwork precisely. If you do not have a designer, our in-house team can create artwork from your brand guidelines.

Do you offer food-safe / FDA-compliant boxes?

Yes. Our food-grade boxes are manufactured from virgin kraft fiber in SQF-certified facilities. They meet 21 CFR 176.170 (FDA indirect food contact) and USDA requirements for direct food packaging. Certificates of compliance are available with every order.

What is the difference between flexo printing and litho-laminate?

Flexographic printing applies ink directly to the corrugated board using rubber plates. It is cost-effective but limited to 1-4 spot colors at 85-133 lpi resolution. Litho-laminate prints on a smooth paper sheet first (at 175+ lpi) and then laminates it to the corrugated, producing photographic-quality full-color graphics.

Can I order a small quantity to test before committing to a large run?

Absolutely. We encourage test orders. For standard sizes, you can order as few as 25 units. For custom die-cuts and printed boxes, we produce sample quantities (typically 25-50 units) at a slight premium to cover tooling, so you can test fit, ship trial units, and get customer feedback before scaling up.

Do you keep dies on file for reorders?

Yes. We store all dies and printing plates for at least 2 years after the last order. Reorders skip the tooling phase entirely, reducing lead time by 3-5 days and eliminating setup costs. We recommend reordering before your stock runs out to avoid gaps.

Before You Order New — Consider Used

We stock thousands of used corrugated boxes in all standard sizes, graded and inspected. For the vast majority of shipping, storage, and internal-use applications, a Grade A used box is functionally identical to a new one — at 40-60% of the cost and with a dramatically smaller environmental footprint.

Reusing a box avoids the ~0.7 kg of CO2, ~80 liters of water, and the tree fiber required to manufacture a new one. If your application does not strictly require virgin board, choosing used is the smarter financial and environmental decision.
