Packaging for pharma and healthcare

Qualified, not just tested

Most industries test a pack, pass, and ship. Regulated healthcare expects a documented rationale: what the pack must achieve, how that was verified, what the acceptance criteria were, and what happens when something changes. A test report is an input to that file, not a substitute for it.

The practical consequence is that change control governs the specification. A board grade substitution that would be routine elsewhere - the mill is out of that liner, here is an equivalent - is a change that may require assessment and possibly re-qualification. Suppliers who do not understand this cause more damage through a well-meant substitution than through any transit failure.

Temperature-controlled transport

Where product is temperature-sensitive, thermal performance must be validated in its own right. ISTA 7E exists for exactly this: it is a thermal transport test standard used to evaluate how a packaging system holds temperature against a defined ambient profile. It is not a substitute for the mechanical profiles - a shipper can hold temperature beautifully and still fail a drop - so thermal and transit validation run alongside each other, not instead.

Cold chain also compounds the moisture problem. Condensation on a shipper moving between environments loads the corrugated with water, which reduces compression strength and can affect label adhesion and print legibility at exactly the moment the pack most needs to be readable.

Tamper evidence and serialization

Tamper evidence must be visible and irreversible: a closure that can be opened and re-closed without trace is not tamper evidence, whatever it is called. Where serialization and track-and-trace requirements apply, the pack has to present codes reliably to scanners - which makes print surface and panel flatness a compliance issue rather than a cosmetic one, and is a common reason to move to a flatter B or E flute at the secondary level.

Fiber choices are constrained here

Recycled content is desirable everywhere and is constrained in parts of this category - by contact requirements, by contamination risk, and by the qualification burden of changing furnish. Fiber-first remains the right default, but in healthcare each substitution has to earn its way through the same evidence process as any other change. We would rather tell you a substitution is not worth the qualification cost than sell you one that is.

The documentation you should expect

• The specification: board grade, flute, construction, coating, tolerances, flute direction.
• Test reports against the profiles chosen for your lane, with the conditioning climate stated.
• The ISO 2859 sampling plan and agreed defect classes for lot acceptance.
• A change-notification commitment, so no substitution reaches you silently.

Ask any supplier for these before the first order rather than after the first deviation. A supplier who cannot produce a sampling plan and a conditioning statement is not equipped for this category.

What we need from you

• The temperature profile and excursion limits, if the product is thermally sensitive.
• Destination markets and the regulatory regime you are qualifying against.
• Serialization, labelling and tamper-evidence requirements.
• Your change-control expectations and who must approve a specification change.
• The lane, dwell time and the humidity at each stage.
