It sounds like a minor detail.
It isn't.
The choice between tape and hot melt adhesive for sealing your cases has real consequences for your line speed, your maintenance schedule, your sustainability targets, and the integrity of your packaging under different conditions.
Here's how to think through it.
Tape is the simpler option to get started with. It's easy to source, straightforward to change, and leaves a visible seal that's easy to inspect. It works well in environments where temperature fluctuates, because tape doesn't re-melt under heat or become brittle in the cold the way adhesive can. It's also the preferred option where tamper-evidence is important — the seal is visually obvious if broken.
Hot melt adhesive delivers a cleaner, faster seal. At high-speed lines it's generally the better choice — the application is precise, the bond forms quickly, and there's no tape roll to change. It also produces a neater finished case, which matters in retail or consumer-facing packaging.
There's no universal right answer. The right choice depends on your line speed, your environment, your SKU range, and what your downstream equipment can handle.
