A six-chair Ontario dental practice cut its pouch spend and its expired-stock write-offs after an overstock audit showed that the three formats on the shelf did not match the instruments the practice sterilizes. Small pouches filled the cupboard but were rarely opened; the largest format ran out mid-week. The fix was a re-derived size ratio, not a new supplier.
Quick facts
- Illustrative, anonymized example based on commonly documented audit findings.
- Formats stocked: 90 x 230 mm, 133 x 254 mm and 190 x 330 mm.
- Small pouches were 58% of shelf stock but 22% of consumption.
How pouch stock drifts out of balance
Pouch mix rarely drifts because someone ordered carelessly. Small formats ship in higher counts per box, so the same spend buys more units and looks like better value, while the larger formats that fit a dressing tray are consumed faster than the reorder point assumes.
- Case-pack gravity. The same dollars buy more small units.
- Instrument creep. A new implant kit arrives and the old ratio is never revisited.
- Substitution. With two formats missing, staff use whatever is on the shelf.
What the audit actually measured
Before reordering, the practice counted four numbers per format over one month: units received, units opened, units expired and stock-outs logged at the sterilizer. That is enough to rebuild the ratio without software.
| Pouch format | Share of stock | Share of consumption | Expired in the month | Change adopted |
|---|---|---|---|---|
| 90 x 230 mm | 58% | 22% | 140 | About 30% of stock |
| 133 x 254 mm | 27% | 44% | 12 | Kept as the workhorse |
| 190 x 330 mm | 15% | 34% | 0 | About 45% of stock |
The format occupying most of the shelf was the one the practice needed least, and the two carrying the clinical load were the ones running out. Nothing pointed to a product fault, only a ratio never reconciled against the cassette inventory.

Loading orientation: where the confusion starts

The question behind this phrasing is fair: when a tray of pouches is loaded, does the film face up or the paper? The rule belongs to the pouch manufacturer and the sterilizer instructions for use, not to a universal convention: steam must reach the contents, and condensate must leave during drying.
- Stand pouches on edge in a rack; flat stacks trap air and slow drying.
- Avoid pressing film against paper, because the film side can block the porous side.
The deciding evidence is the cycle result, not orientation trivia: a chemical indicator in the pouch, and a biological indicator run on the schedule your province requires. Visible moisture or a failed indicator means reprocessing.
pouch vs wrap for cassette sterilzation
A cassette is a rigid, perforated container processed as a unit. Normal practice is to wrap it to size or run it in a rigid container rather than force it into a peel pouch. Film can abrade against a cassette edge, the seal is stressed by the weight, and standard pouches rarely fit a full cassette footprint. Peel pouches stay faster to seal, label and open for loose instruments and small trays.
Rebuilding the ratio
The practice rewrote its reorder points: small pouches fell to about 30% of stock, the middle format stayed the workhorse, and the largest rose to 45%. Cut-to-length material absorbed the odd long instrument, so no fourth SKU was needed. A 50 m roll of CliniEco sterilization roll with pre-cut sheets lets the team match a length to the load rather than guess at a pouch size.
Seal quality became the other half of the fix. A constant-heat unit such as the CliniEco 200 °C constant-heat pouch sealer with a 12 mm seal produces a repeatable band that can be checked at a glance. Monitoring runs alongside it: in Ontario, the RCDSO requires a biological indicator for each sterilizer on every day it is used — daily, not weekly. The weekly baseline is the CDC / AAMI ST79 standard in most US states, which is why guidance written for another jurisdiction can mislead.
What the practice kept after the review
- A tally sheet at the sterilizer, completed whenever a box is opened.
- Reorder points written in weeks of supply rather than boxes.
Teams testing monitoring supplies can start with a five-pack biological indicator trial. Two posts are worth reading before the next reorder: sterilization pouches compared: Crosstex, Sure-Check and Medline, and three common autoclave pouch sealing errors and their root causes.

Frequently Asked Questions
How often should pouch stock be re-counted?
Quarterly is enough for a stable practice. Count units opened and expired per format over four weeks; that ratio shows which format carries the clinical load.
Should pouches be loaded with the plastic side up?
There is no universal rule. Follow the pouch manufacturer and sterilizer instructions: stand pouches on edge, avoid pressing film against paper, and let the indicator and drying result confirm the cycle.
Can a cassette be sterilized inside a peel pouch?
It is not recommended. Cassette edges stress the film and seal, and standard pouches rarely fit a full footprint. Wrap to size or use a rigid container.
How do I keep small pouches from expiring on the shelf?
Set reorder points in weeks of supply, reduce the small format to the share of consumption it earns, and use cut-to-length roll material for long instruments.
