Custom Quad Seal Pouch Boxes

Four Seals, Endless Strength and Style

Quad seal pouches are made with two side gussets and four corner seals, allowing for more space and a stable, square shape. Ideal for products like coffee, pet food, protein powders, and grains, these pouches combine structure with style.

Materials

We use high-performance laminates to provide strength and protection without adding bulk.

• PET/PE – Lightweight, flexible, and moisture-resistant
• BOPP/Poly – Great for printed designs and tear resistance
• PET/AL/PE – Foil lining for light and oxygen protection
• Recyclable options – Sustainable materials for eco-minded brands

Sizes

From shelf-ready retail packs to large-format bags, our sizes are tailored to your needs.

• Small for tea, snacks, and trial portions
• Medium for rice, nuts, or dry foods
• Large for pet food, bulk coffee, or protein powder
• Custom widths and gusset depths available

Printing

The four panels offer maximum space for branding and design.

• Full-color digital or rotogravure printing
• High-resolution imagery on all sides
• Matte, gloss, or soft-touch finishes
• Metallic, embossed, or spot UV details

Add-ons

Function meets convenience with every pouch feature.

• Zippers for resealability
• Tear notches and degassing valves
• Transparent windows for product visibility
• Handle punches for easier carrying

The 3Ps Approach

Presentation

With side gussets and four printable panels, quad seal pouches provide a bold, structured look that enhances product visibility and brand recognition.

Preservation

Multi-layer laminates seal out air, light, and moisture—keeping your contents fresher for longer and extending shelf life.

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.
