Sterilization pouches are bought in cases, not boxes. In Canada the practical routes are a dental distributor, a medical products wholesaler that holds Canadian stock, and an importer selling case quantities directly to clinics. The figure that decides the deal is not the case price: it is the case price divided by the number of pouches inside, and that figure moves more than most clinics expect between a 200-pack and a 1,200-pack of the same size.
This guide covers where to buy, how to work out the real cost per pouch, which sizes a clinic actually consumes, and what to write on the purchase order so the next case matches the last one. For the pouch itself, the reference line is the Class 4 dual-indicator sterilization pouch, 10 x 15 in (25 x 38 cm), 200 per pack.
Where can a Canadian clinic buy sterilization pouches?
Three routes cover almost every purchase, and they differ mainly in how much of the price is logistics rather than paper and film.
- Dental distributor. Fast, sells in boxes as well as cases, and usually carries the same brand your team already uses. The convenience premium is real, and it is paid per pouch.
- Medical products wholesaler with Canadian stock. Case and half-case quantities, one invoice across several product lines, and delivery in days rather than weeks. This is the common route for clinics that order pouches together with gloves, tape and indicators.
- Importer or manufacturer selling direct. The unit price is usually the lowest, but the commitment is a full case of one size, and lead time depends on whether the stock is already in Canada or arrives with the next container.
Ask each route the same two questions before comparing anything: is the stock held in Canada, and what pouch count is in the case. A supplier who cannot answer both from the product page is telling you how the order will go.
How do you work out the price per pouch?
Divide, then correct for what you throw away. The arithmetic is simple; the mistake is comparing case prices between different pouch counts.
| What you compare | How to calculate | Why it matters |
|---|---|---|
| Cost per pouch | Case price ÷ pouches per case | A 200-pack and a 1,200-pack are not comparable as case prices |
| Cost per instrument set | Cost per pouch × pouches used per set | A set that needs two pouches doubles the real cost |
| Cost per usable pouch | Cost per pouch ÷ (1 − reject rate) | A 5% seal failure adds about 5% to the true unit cost |
| Landed cost | Case price + freight + duty ÷ pouches | Freight per case is fixed, so small cases carry a heavier share |
Worked example: a case of 200 pouches invoiced at $24.00 is 12 cents per pouch; the same size at 1,200 pouches for $108.00 is 9 cents per pouch before freight. If your team rejects one pouch in twenty at the sealer, the 9-cent pouch is really 9.5 cents of usable packaging.
Which pouch size fits which instrument set?
Most clinics try to run two sizes and end up with four. The table below is the usual mapping; a set that will not sit flat inside the pouch is the wrong size regardless of what the label says.
| Pouch size | Typical contents | Practical note |
|---|---|---|
| 2.25 x 4 in | Single probe, scaler tip, small bur block | Overfilled quickly; useful for high-volume small items |
| 3.5 x 5.25 in | Hand instruments, forceps, small scissors | The workhorse size in most dental and urgent care trays |
| 5.25 x 10 in | Procedure tray, several handpieces, curettes | Leave the fold clear; do not let the tray press the seam |
| 7 x 13 in | Large tray, bowl, multiple sets in one pack | Heavier load; check that the pouch does not touch the chamber wall |
| 10 x 15 in (25 x 38 cm) | Standard instrument set, mixed small items | Metric sizing; confirm units when comparing quotes |
How many pouches does a two-chair clinic use in a month?
Count the instrument sets per day, not the patients. A two-chair practice running 20 appointments a day with roughly one instrument set per appointment uses about 400 pouches a month on a five-day week, before rejects and before the odd oversized set that needs a larger size. Add the reject rate, then add a buffer of two weeks of stock so a delayed order does not stop the sterilizer, and a clinic that thought it needed one case a month usually finds it needs one and a half.
That is the par level. Put it on the purchase order as a recurring quantity, and re-check it when the appointment book changes rather than when the shelf is empty.
What should the purchase order specify?
- Pouch size in one unit system only, and the pack count per case.
- Indicator class the pouch carries, so the packing team is not guessing.
- Seal validation data the supplier can produce on request, not only at the first order.
- Lot number on the shipping documents, so the case can be traced if the supplier recalls a run.
- Whether substitutes are permitted. A quiet substitution to a different film is a common surprise in a standing order.
How do you check a new supplier before switching?
Order one case, run the sealer validation on the new film, and log the lot. Pouch paper and film change seal behaviour slightly, so the temperature or dwell time that worked on the previous brand may not hold. Two other checks are worth doing on the first case: confirm the indicator reacts evenly across the sheet, and confirm the pouch does not delaminate when peeled after a full cycle. If either fails, the case is a sample that cost you money, not a supply contract.
Keep a second approved supplier on file. A single-source pouch line is a single point of failure for every instrument in the building.

Frequently Asked Questions
Are sterilization pouches sold by the case in Canada?
Yes. Most Canadian suppliers sell pouches in cases of 200 or more, and some will split a case into boxes for a first order. The case count is the number you need in order to compare unit price.
How do I calculate the cost per pouch?
Divide the case price by the number of pouches in the case. Then add freight and duty and divide again for landed cost, and divide once more by the share of pouches that pass the seal check.
Which pouch sizes should a dental clinic stock?
Two sizes usually cover most work: 3.5 x 5.25 in for hand instruments and a larger size such as 5.25 x 10 in or 7 x 13 in for trays. Ordering four sizes fragments the par level and raises the risk of a stockout on the size you use most.
Can sterilization pouches be reused?
No. The paper layer loses porosity and the seal channel weakens after one cycle, so a reused pouch cannot be relied on to let steam in and keep organisms out. Treat every pouch as single use.
