Custom Regular Slotted Container

Built for Durability and Simplicity

RSCs are the backbone of modern packaging because of their simple design and maximum protection. With flaps that meet in the middle and a clean-cut layout, these boxes are easy to seal and protect contents during shipment.

Materials

We offer a wide range of material options to match the weight and fragility of your products:

• Single-wall corrugated: Lightweight and durable
• Double-wall corrugated: Extra strength for heavy items
• Kraft board: Eco-friendly and recyclable
• White corrugated: Clean surface for branding

Sizes

We tailor sizes to fit any product without wasting space:

• Small RSCs for electronics, tools, or cosmetics
• Medium RSCs for apparel, kitchenware, or hardware
• Large RSCs for industrial, bulk, or wholesale use
• Custom-fit boxes to minimize filler material

Prints

Highlight your brand with full-color printing and visual detailing:

• CMYK and Pantone color models
• Inside and outside printing
• Custom brand logos, barcodes, and product info
• Matte or gloss surface finishes

Add-ons

Upgrade your boxes with features for both function and presentation:

• Die-cut handles for easy carrying
• Tear strips for fast opening
• Internal dividers or inserts for organized packing
• Printed handling icons and shipping labels

Types of Boxes

While the regular slotted container is the standard, we offer variations that match different applications:

• Standard RSC with four flaps
• Full overlap RSC for extra cushioning
• Half-slotted containers for easy top loading
• Reinforced RSCs with glued seams

3Ps Approach

We ensure every RSC meets the core 3Ps of Packaging—Presentation, Preservation, and Protection—so your products arrive safely and professionally.

Presentation

Get a polished look with branded prints, neat finishes, and structural precision that reflects your product’s quality.

Preservation

Our boxes are built to withstand climate changes, moisture, and storage wear, helping to extend product shelf life and presentation.

Protection

Sturdy corrugated layers shield your products from compression, impact, and environmental damage during shipping or stacking.

Upgrade to Premium Packaging

Even basic RSCs can be elevated with premium finishes to match high-end or client-facing shipments:

• Foil stamping or embossed branding
• Inside-printed panels or instructions
• Custom tape, labels, or seals
• Soft-touch coatings or varnishes

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.
