Key Features
About Seal End Boxes
Seal end boxes — also called glued-end cartons or tuck-and-seal cartons — have both the top and bottom closures glued shut at the manufacturing facility. The glued closures provide maximum structural integrity and tamper evidence, making seal end boxes the preferred format for pharmaceutical, nutraceutical, and food safety applications where consumer confidence in package integrity is paramount.
Unlike tuck-in closures that can be opened and reclosed without evidence, glued seal end closures must be visibly torn to open — creating clear evidence of package access. The pre-glued bottom means the box is self-supporting when erected from flat, requiring no bottom tuck operation at the filling line.
Seal End Boxes in Pharmaceutical Packaging
Seal end boxes are one of the standard pharmaceutical carton formats because the glued closure provides both structural integrity and tamper evidence that tuck-in closures cannot match. When a pharmacist or consumer opens a seal end pharmaceutical box, the glued closure must be torn — and a torn closure is immediately visible as evidence of prior opening. This tamper evidence is a regulatory and consumer confidence requirement for many pharmaceutical product categories.
Automated Filling with Seal End Boxes
Seal end boxes are compatible with automated cartoning machines configured for glued-end formats. The pre-glued bottom erects automatically when the box sides are spread. The top is filled from above, then the glued top closure is applied and pressed — either manually or by machine. The gluing operation adds machine cost but eliminates the reliability issues associated with tuck-in closures in high-speed automated environments.

Seal End Boxes FAQs
What is the difference between seal end and tuck end boxes?
Tuck end boxes are closed by manually tucking flaps — closures can be opened and reclosed without visible evidence. Seal end boxes are glued shut at the factory — opening requires visibly tearing the glued closure, providing clear tamper evidence.
Are seal end boxes more expensive than tuck end boxes?
Yes. The pre-gluing operation at the manufacturing facility adds modest cost compared to tuck end boxes. For applications requiring tamper evidence or maximum closure integrity, the cost premium is typically justified.
Can seal end boxes be opened from both ends?
Typically, seal end pharmaceutical boxes are designed to open from the top only — the bottom is permanently glued. Some consumer applications use both ends sealed with a perforated opening indicator on one end for controlled access.
What adhesive is used for seal end box gluing?
Hot melt adhesive is the standard for seal end box gluing — it provides a strong, immediate bond compatible with high-speed production. Food-safe hot melt adhesives are available for food product applications.
What is the minimum order for custom seal end boxes?
Custom seal end boxes start at 100 units. The pre-gluing operation is performed in-line during production for efficient unit economics at standard quantities.
