Corrugated Box Manufacturers

Engineered for Protection. Designed for Impact.

Our corrugated boxes aren’t just strong — they’re smartly designed. Whether you’re shipping fragile items or packing retail products, we ensure each box is built for its intended purpose with the right strength, size, and finish.

Materials

We manufacture corrugated boxes using premium fluted cardboard that balances strength with flexibility:

• Single-Wall Corrugated – Ideal for lightweight to medium-weight products and eCommerce orders
• Double-Wall Corrugated – Extra strength for heavier or more delicate items
• Triple-Wall Corrugated – Used for industrial or bulk shipping where maximum protection is required
• Kraft or White Liner – Choose a natural, eco-friendly brown look or a white surface for vivid printing

All our materials are recyclable, crush-resistant, and food-safe.

Sizes

No matter your product shape or weight, we create corrugated boxes that fit perfectly. Custom sizing ensures that your packaging minimizes empty space, lowers shipping costs, and prevents product movement. We offer solutions for compact retail boxes, subscription mailers, oversized cartons, and everything in between.

Printing

Our corrugated boxes are print-ready and fully customizable inside and out:

• CMYK and Pantone (PMS) printing for brand consistency
• Digital, offset, or flexographic printing based on volume
• Exterior and interior prints to create immersive unboxing experiences
• Optional finishes: Matte, gloss, or soft-touch coating

Include branding, handling instructions, barcodes, or promotional graphics in a way that stands out.

Add-ons

Add form, function, or flair with the right enhancements:

• Custom inserts, partitions, or foam padding for secure transit
• Easy-tear strips, locking flaps, or auto-bottoms for usability
• Embossing, debossing, or foil stamping for branding impact
• Die-cut windows, handles, or display cutouts for convenience or presentation
• Spot UV to highlight specific design areas

These upgrades give your packaging a professional edge while boosting user experience.

When measuring a custom box, there are a few technical specifications that must be considered to ensure proper design, manufacturing, and fit for the product. Here are the major technical things to measure a custom box:

Inside Dimensions (Critical for Product Fit)

• Length (L): The longest side of the box measured inside from one corner to the opposite corner.
• Width (W): The shorter side of the box measured inside perpendicular to the length.
• Depth/Height (D or H): Measured inside from the bottom to the top opening of the box. Always specify that dimensions are given in Length × Width × Height.

Outside Dimensions (Important for Shipping & Storage)

• Measure the outer surfaces of the box including material thickness.
• Outside measurements are used for pallet stacking, warehouse spacing, and shipping compliance.

Material Thickness (Board Caliper)

• The thickness of the packaging material (e.g., corrugated board, rigid stock, cardstock).
• Impacts both the internal usable space and external dimensions.

Flap Measurements

• For boxes with flaps (e.g., mailer or shipping boxes), measure:
• Inner flaps: Ensure they meet in the middle without overlapping too much.
• Outer flaps: Allow proper sealing without gaps.

Tolerances

• Account for manufacturing tolerances (usually ±1/16" or ±2mm depending on material).
• Ensure the product fits without being too tight or loose.

Volume Capacity

• Calculate internal cubic capacity (L × W × H).
• Helps in determining how much space the product will occupy and shipping efficiency.

Product Orientation

• Decide how the product sits inside the box and measure accordingly.
• Orientation affects whether length or width is the primary dimension.

Die-Cut Openings or Windows

• Measure exact placement, height, and width for any cutouts.
• Ensure structural integrity when adding windows.

Printing Bleed & Safe Zones

• Include measurements for:
• Bleed area: Extra space beyond the cut line for printing.
• Safe zone: Inner area where critical text or logos should be placed.

Closure Type & Locking Tabs

• Measure slots, tabs, or locks for boxes with custom closures.
• Precision is required to avoid misalignment during assembly.

Packaging Style

• Folds, creases, and scores must be measured for accurate dieline creation.
• Different styles (e.g., RSC, tuck-end, mailer, sleeve) require specific panel measurements.
