Custom Seal End Cartons & 1-2-3 Auto-Bottom Retail Boxes
Precision-engineered seal end boxes designed for automated high-speed production lines, tamper-evident retail closures, and heavy consumer goods. Featuring overlapping adhesive-ready dust flaps and optional 1-2-3 snap-lock bottoms that support dense, heavy retail items with zero bottom blowout.
1. Automated Packaging Line & High-Volume Compatibility
Seal end cartons are the undisputed industrial standard for high-volume retail goods. Engineered with precision die-cut scoring and calibrated flap grain direction, these boxes run flawlessly through automated cartoning machinery or can be glued manually with cold/hot melt adhesives. Overlapping end flaps guarantee tamper evidence: the box cannot be opened without visibly tearing the paper fiber.
2. 1-2-3 Snap Lock Bottom Bottom Strength
For manual assembly lines, our 1-2-3 auto-bottom configuration offers unbeatable weight support. Three interlocking base flaps snap together securely in three steps without tape or glue, bearing up to 15 lbs of concentrated product weight—making them ideal for glass jars, dry grocery, supplements, and heavy hardware.
3. Structural Paperboard Caliper (16pt – 26pt SBS & CCNB)
Tailored to high-speed sealing and structural stacking demands:
- Solid Bleached Sulfate (SBS): Premium bright white virgin cardstock for cosmetics, pharmaceuticals, and high-end consumer packaged goods.
- Clay Coated Newsback (CCNB): High-density recycled paperboard with a clay-coated white exterior and grey kraft interior, providing superior cost-efficiency for dry food and household retail.
- Natural Kraft Cardstock: Eco-conscious biodegradable packaging with high tear resistance.
