Description
Description
Microppose Laboratory Poly Film is a stretchy, scissor-free alternative to Parafilm for sealing petri dishes: it pulls cleanly off the roll, stretches around the plate and tears by hand with no tools.
Each roll is 1.25" wide and 280 feet long, enough for hundreds of plates. The film locks plates against drying and contamination without bonding dishes together when stacked, and it flexes instead of cracking under daily lab use. It's a cost-effective way to seal everything from fresh transfers to long-term stock cultures.

Why growers switch to Microppose poly film
- No scissors needed – Tears cleanly by hand, which means one less tool and one less contamination vector in the flow hood.
- Super elastic – Stretches around the rim of the dish for a snug seal that flexes instead of cracking.
- Won't bond plates – Sealed dishes don't stick together when stacked.
- Crystal clear – Keeps the full surface of the plate visible for inspection.
- Crack-resistant – Holds up to repeated handling, refrigeration and stacking without splitting at the seam.
What's included
- One roll of Microppose Laboratory Poly Film, 1.25" (32 mm) x 280 ft
How to seal a plate
- Pull a length. Draw film off the roll — a little more than the plate's circumference.
- Tear by hand. Snap it off cleanly; no scissors required.
- Stretch and wrap. Stretch the film around the seam between the lid and base.
- Press to seal. Overlap the end and press it down so the seal holds.
- Stack and store. Stack sealed plates for incubation or refrigerated storage — they won't bond together.
How long does a roll last? One roll typically lasts months for active hobbyists and weeks for working production labs.
Microppose Poly Film vs. Parafilm
Most growers know Parafilm as the standard for sealing plates. Here's how Microppose Poly Film compares in day-to-day use:
| Feature | Microppose Poly Film | Traditional Parafilm |
|---|---|---|
| Cutting | Tears cleanly by hand — no scissors | Typically requires scissors to cut |
| Stacking | Doesn't bond plates when stacked | Can bond plates together if stacked too tightly |
| Elasticity | Highly elastic; stretches easily over the rim | Less elastic; more prone to tearing during application |
| Durability | Stays crack-resistant with daily use | Can crack or split with handling |
| Cost | Lower cost per foot for high-volume work | Higher per-foot cost in long rolls |
Where mycologists use it
- Sealing inoculated plates after transfer to prevent contamination during incubation.
- Long-term plate storage in the refrigerator without the agar drying out.
- Stock culture preservation — sealing master plates that get pulled out repeatedly for transfers.
- Transport — sealing colonized plates for shipment or moving between work areas.
- Small vessels — wrapping jar lids or other culture vessels where a flexible secondary seal helps.

FAQ
Is this a Parafilm alternative?
Yes. It seals petri dishes like Parafilm but tears by hand, stretches more easily and doesn't bond plates together when stacked.
Do I need scissors?
No. The film tears cleanly by hand.
How big is the roll?
Each roll is 1.25 inches (32 mm) wide and 280 feet long, enough for hundreds of plates.
How long will a roll last?
One roll typically lasts months for active hobbyists and weeks for working production labs.
Can I refrigerate sealed plates?
Yes. The film holds up to refrigeration, stacking and repeated handling without splitting, and helps keep agar from drying out in long-term storage.
