Custom Seal End Boxes | Tamper-Evident Glued Closure Pharmaceutical Packaging

Seal end boxes feature fully glued top and bottom closures — both ends are sealed with adhesive during the manufacturing process, creating airtight, tamper-evident closures that require the glued seal to be visibly broken for product access. Unlike tuck end boxes where the closure flaps fold without adhesive, seal end boxes have their end panels bonded with hot-melt or cold-glue adhesive before delivery, arriving at the filling station pre-sealed at one end and requiring only product insertion before the second end is sealed at the filling line.

Tamper Evidence Function

The seal end box's primary distinguishing characteristic is its tamper evidence — a glued seal that must be physically broken to access the product creates a visible tamper indicator that consumers, retailers, and regulatory bodies can verify. For pharmaceutical products, this tamper evidence is a regulatory requirement. For premium food products, it communicates product integrity. For consumer goods requiring authentication, the broken seal signals whether a package has been previously opened.

Seal End Production Process

Seal end boxes are produced with one end pre-glued at the carton manufacturing facility, arriving at the filling station as flat cartons with one end permanently closed. The carton is erected, product is inserted through the open end, and the second end is sealed by the filling line's gluing mechanism — typically hot-melt adhesive applied to the closing flaps before pressing. This two-stage sealing process requires the filling line to have a gluing station, distinguishing seal end production from tuck-end filling that requires no adhesive application equipment.

Seal End Boxes and Pharmaceutical Compliance

Seal end boxes are standard in pharmaceutical packaging because the glued closure provides tamper evidence that tuck end boxes fundamentally cannot — a tuck end can be opened and reclosed without visible evidence of access, while a glued seal end must be physically broken to open, leaving visible evidence of access that cannot be restored to its original sealed state. FDA regulations for OTC pharmaceutical products require tamper-evident packaging, and the glued seal end is one of the primary tamper-evident structures used to meet this requirement. Pharmaceutical seal end cartons must also accommodate serialization: a matte varnish zone on a specified panel where the DSCSA 2D datamatrix code is applied at the filling line.

Hot-Melt vs. Cold-Glue Sealing at the Filling Line

Seal end boxes filled at production lines use either hot-melt adhesive (applied hot as a molten bead, cooling rapidly to create a strong bond in seconds) or cold-glue adhesive (applied at room temperature, requiring clamp time to cure) for the filling-line end seal. Hot-melt is the dominant pharmaceutical and food filling line standard because its rapid set time enables high-line speeds without extended clamping. Cold-glue is used for applications where heat from hot-melt application could damage product or where filling equipment limitations preclude hot-melt. The appropriate sealing system is specified based on the customer's filling line equipment.

Seal End Boxes in Loveland — FAQs

What is a seal end box?

A seal end box has fully glued top and bottom end closures — both ends are sealed with adhesive, either at the carton manufacturing facility (for pre-glued configurations) or at the filling line. The glued closure must be physically broken to access the product, creating visible tamper evidence that tuck end boxes cannot provide.

Why are seal end boxes required for pharmaceutical products?

FDA regulations under 21 CFR Part 211.132 require tamper-evident packaging for OTC drug products. The glued seal end is one of the primary tamper-evident packaging structures because the adhesive bond must be physically broken to access the product, leaving visible evidence of tampering that cannot be concealed without specialized equipment.

Do I need special filling equipment for seal end boxes?

Yes. Seal end boxes require a gluing station on the filling line — typically a hot-melt glue applicator that applies adhesive to the closing flaps before pressing them closed. This is standard equipment on pharmaceutical, supplement, and food filling lines. Operations without gluing capability should specify tuck end, auto-lock, or snap lock bottom configurations instead.

Can seal end boxes include child-resistant closures?

Yes. Child-resistant seal end configurations use scored panel mechanisms that require simultaneous pressing at specific points before the seal can be broken — a design that passes CPSC 16 CFR 1700.20 child resistance testing while maintaining the tamper-evident sealed appearance. CR seal end cartons are standard for prescription drug packaging.

What is the minimum order for custom seal end boxes?

Our minimum order is 100 units for custom seal end boxes. Pharmaceutical seal end cartons require GMP manufacturing documentation and serialization surface specification — these are addressed during the order setup process before production.
