Cardboard Box Manufacturers

Packaging that Does More Than Just Contain

Our boxes are engineered to carry your product safely, represent your brand clearly, and create a smooth unboxing experience. As experienced cardboard box manufacturers, we understand how packaging impacts both logistics and customer satisfaction — and we optimize both.

Materials

We manufacture using premium-grade cardboard suited for both shipping and retail presentation:

• Corrugated Cardboard – Durable, impact-resistant, and perfect for heavy-duty transit. Available in single-wall, double-wall, or triple-wall depending on your product’s weight and fragility.
• Folding Carton (Paperboard) – Lightweight and ideal for custom retail packaging like cosmetics, supplements, or food products.
• Kraft Board – Eco-friendly and biodegradable with a rustic appeal, great for organic or sustainable brands.

Every board is food-safe, print-ready, and customizable with a variety of finishes and coatings.

Sizes

Every box we manufacture is custom-sized to fit your product:

• Compact boxes for jewelry or electronics
• Medium cartons for apparel or beauty kits
• Large shipping boxes for bulk orders

We design the perfect size to reduce waste, optimize space, and ensure product security during handling.

Printing

Cardboard doesn’t have to be plain. We offer premium printing to help you showcase your brand:

• Full-color CMYK and Pantone (PMS) options for high-impact visuals
• Digital, offset, or flexographic printing based on order volume
• Matte, gloss, or soft-touch coatings for the finish you want
• Inside and outside print options available for immersive unboxing
• Branding, product info, barcodes, or promotional graphics

Add-ons

Make your box more functional or visually impressive with smart upgrades:

• Die-cut windows for product previews
• Custom inserts, dividers, and trays for organized packaging
• Embossing, debossing, or foil stamping to highlight key elements
• Spot UV for shine and contrast
• Perforations, tear strips, or locking flaps for ease of use

These add-ons don’t just elevate the packaging — they elevate your entire customer 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.
