Materials

As experienced cardboard box suppliers, we use premium-grade boards that combine structure, flexibility, and printability:

• Corrugated Cardboard – Designed for strength and impact resistance, ideal for shipping, eCommerce, and storage.
• Folding Carton (Paperboard) – Thin, sleek, and perfect for product packaging in retail and display settings.

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.
