How do you calculate packaging damage risk?

Multiply the severity, occurrence, and detection scores. With severity 6, occurrence 4, and detection 3 the risk priority number is roughly 4.6 on the tool's normalized scale, letting you rank it against other packaging failure modes.

What is a good packaging damage risk score?

Lower is better, and there is no universal threshold - it depends on your scoring scale. Teams usually set an action line (for example, address anything above a chosen RPN) and always act on any failure mode with a top severity regardless of the product.

Why does detection matter so much for barrier films?

A barrier breach like a micro-pinhole often causes no immediate visible defect but ruins shelf life or sterility later. If detection is poor (a high detection score), even a moderate-severity failure jumps up the priority list.

Severity vs occurrence vs detection - which should I fix first?

Reducing occurrence removes the failure at the source and is usually the best lever. Improving detection only catches problems already made. Severity is often fixed by design and hardest to change, so target occurrence, then detection.

Is this the same as an FMEA RPN?

Yes. It is the classic risk priority number applied to packaging: severity times occurrence times detection. The value here is normalized so you compare packaging damage modes consistently on one scale.

How often should packaging damage risk be re-scored?

Re-score after any corrective action, a new complaint, a film or seal-recipe change, or a new distribution lane. Abrasion and seal risks in particular shift when transit packaging or pallet patterns change.

Specialty Films, Membranes & Barrier Materials calculator

Packaging Damage Risk Calculator

Packaging damage risk is an FMEA-style risk priority number for the ways a specialty film, membrane, or barrier pouch can fail in handling, sealing, or transit. You multiply how bad the failure is (severity), how often it happens (occurrence), and how likely you are to catch it before it ships (detection). Quality engineers and packaging developers on barrier lines use it to rank failure modes - pinholes, seal skips, delamination, abrasion through the top web - so scarce corrective-action effort goes to the risks that actually threaten shelf life or sterility. Because a barrier breach can silently spoil product weeks later, a high detection score (hard to catch) is often what pushes a risk to the top of the list.

What this calculator does

Estimate packaging damage risk for specialty films, membranes and barrier materials using production-ready inputs so teams can rank risks and decide which issue needs containment, controls, or escalation first.
Use it when packaging damage risk in specialty films, membranes and barrier materials needs a defensible ranking against other specialty films, membranes and barrier materials risks for the next review.
It multiplies severity, occurrence, and detection scores into a single risk priority number so packaging failure modes can be ranked against each other.

Formula used

Packaging damage risk score = packaging damage risk severity score × packaging damage risk occurrence score × packaging damage risk detection score
Use the same scoring scale across comparable packaging damage risk risks.

Inputs explained

Damage severity if a barrier breach reaches the customer:
Likelihood of packaging damage occurring:
Ability to detect damage before shipment:

How to use the result

Use it during packaging FMEA, PPAP, or a customer complaint review to decide which barrier or seal failure mode to address first.
It is a relative ranking, not a probability - a 4.6 has no physical meaning on its own and is only useful when all failure modes are scored on the same scale.

Current U.S. benchmarks

The producer price index for plastic resins and materials stands at 319.371 (BLS, May 2026), up 19.5% from a year earlier. Quotes priced off last quarter's material cost miss this move.
Global copper trades at $13,484 per tonne (IMF via FRED, May 2026), up 41.5% in a year, and U.S. industrial electricity averages 8.66 cents per kWh. Both feed electrified-hardware unit economics.
