Shipping & Mailing
37 products
Dental lab mailers are the part of the workflow a practice actually sees. This shelf carries about 37 listings from Keystone Industries covering mailers and shipping boxes, packaging accessories and the sealer parts that go with them.
A mailer system has three parts: a rigid outer shell that survives the carrier, an inner case box or foam that immobilises the work, and a closure that can be opened and reclosed without tools. Keystone medium mailers are stocked complete in white, gray, light blue and yellow, which is how most labs assign a colour to a practice or to a case type so returning boxes sort themselves on the receiving bench. Smaller red, blue and charcoal components are stocked in bulk counts of 100, 500 and 1,000 for labs that build their own mailer combinations.
Lab mailing boxes are chosen by what is inside. A crown travels in a small rigid box with foam on all six sides; a full arch case or a set of impression mailers carrying models and a bite registration needs both more volume and more crush resistance. Bag sealing for impressions and appliances is covered by impulse sealer supplies, including replacement heating elements.
How to choose
- Pick the mailer size from the largest thing you routinely send, not the average case.
- Use colour as a sorting system: one colour per practice, per shift or per case type saves time on the receiving bench.
- Buy complete mailers when you want a system out of the box; buy components in bulk counts when you assemble your own.
- Check crush resistance for models and impressions, which are heavy relative to their size and unforgiving of a soft box.
- Keep the return trip in mind: a mailer a practice can reclose easily comes back, and one it cannot does not.
- Stock the consumables around the mailer too, including sealer elements and bags, so a shipment never waits on a part.
Frequently asked questions
What is a dental lab mailer?
A purpose-made shipping container for dental work: a rigid outer shell, an inner box or foam that holds the case still, and a reclosable lid. It protects models, impressions and finished restorations in the post between a practice and a laboratory, and most systems are designed to make repeat round trips.
How should impressions be packed for shipping?
Disinfect and drain the impression, let it stabilise, bag it, and support the tray so it cannot flex against the box wall. Ship promptly, since dimensional change in an impression is driven by time and storage conditions, and pack the bite registration and prescription so they cannot press against the impression surface.
Why are mailers sold in different colours?
So a lab can assign one colour per practice, per route or per case type. When boxes come back, colour alone routes them to the right shelf without opening them, and a practice can tell at a glance that the box on the counter belongs to its laboratory.
Can I buy mailer components separately?
Yes. Complete medium mailers are stocked ready to use, and components are stocked in bulk counts of 100, 500 and 1,000 for labs that assemble their own configurations or that replace inner boxes more often than outer shells.
How fast do mailers ship?
In-stock mailers and shipping boxes ordered by 3 PM ET ship the same day from Northern Virginia. Because packaging is light and bulky, ordering a full pack quantity at once is usually cheaper per unit delivered than reordering in small amounts.
