Tamper-Evident Glue Flaps. Automated Packing Performance.
Glued-shut ends that cannot be opened without visible damage. Tamper-evident for food and pharma.
The industrial workhorse of retail folding cartons. Seal end boxes feature overlapping top and bottom glue flaps designed to be machine or hand sealed, delivering tamper-evident security and maximum stacking strength.
Custom seal end boxes (also known as glue flap cartons or auto-seal cartons) are the industry standard for high-speed automated packaging lines. Engineered with overlapping top and bottom flaps that are glued shut using hot-melt or cold adhesive, these boxes provide exceptional tamper evidence and structural compression strength.
Unlike tuck top boxes which can be reopened without damage, seal end cartons must be torn open, guaranteeing product freshness and integrity for dry foods, pharmaceuticals, consumer electronics, and retail goods.
Cubit offers custom paperboard calipers (18pt to 24pt SBS/Kraft), E-flute/F-flute corrugated options, full-color offset printing, moisture-resistant coatings, fast 5-7 day production, and a low 100-unit MOQ.
