Custom Seal End Boxes

What is a seal end box?

A seal end box is a folding carton with flaps at the top and bottom that are closed with glue instead of tucked in. The result is a clean, square box with a closure that shows if it has been opened. It is the familiar shape of a cereal or cracker box, and it can be filled by hand or on packing machines.

When to choose a seal end box

• You sell dry food such as cereal, snacks, pasta, tea or baking mixes.
• You want a closure that shows tampering at a glance.
• Your packing is done on a line, or in high volume by hand with glue.
• You need a tall, flat front panel for strong shelf graphics.

If customers will open and reclose the box many times, a tuck end box may suit better, or you can add a tear strip or perforated opening.

Materials and finishes

Seal end boxes are usually made from paperboard. SBS gives a bright white surface for vivid color, while kraft gives an unbleached, natural look. Recycled paperboard is another common choice for dry goods. Options include:

• Full-color print on all panels
• Matte or gloss coatings and aqueous coating
• Tear strips, perforated openings or pour spouts
• Window cutouts with clear film

If the product touches the board directly, use an inner bag or liner and check the food-contact requirements that apply to your product.

Design tips

• Plan where the nutrition panel, barcode and ingredient list will sit before you design the front.
• Keep artwork clear of glue areas shown on the dieline, since glue does not bond well over some coatings.
• Use the top panel: boxes are often seen from above on low shelves.
• Ask for opening instructions to be printed if you add a tear strip.
