Easy-Seal Poly Tape for Agar Plate Work · Super Elastic · Scissor-Free
Simplify your agar workflow with Microppose Laboratory Poly Film—a stretchy, scissor-free alternative to Parafilm for sealing petri dishes. Designed for maximum elasticity and ease of use, this tape pulls cleanly off the roll, stretches around the plate, and tears by hand without any tools.
With 1.25" width and 280 ft per roll, you get a cost-effective sealing solution that locks plates against drying and contamination—without bonding dishes together or cracking under daily lab use.
Key Features
280 ft Per Roll
A 1.25" wide, 280-foot roll covers hundreds of plates per roll for serious agar work.
Super Elastic
Stretches around the rim of the dish for a snug seal that flexes instead of cracking.
No Scissors Needed
Tears cleanly by hand — one less tool in the flow hood, one less contamination vector.
Won’t Bond Plates
Unlike traditional sealing films, this tape doesn’t stick dishes together when stacked.
Crystal Clear
Transparent film 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.

Microppose Poly Film vs. Parafilm
Most growers know Parafilm as the standard for sealing plates. Microppose Poly Film is the workflow upgrade many labs are switching to. Here’s how they compare in day-to-day use:
Microppose Poly Film
- Tears cleanly by hand — no scissors
- Doesn’t bond plates when stacked
- Highly elastic, stretches easily over the rim
- Stays crack-resistant with daily use
- Lower cost per foot for high-volume work
Traditional Parafilm
- Typically requires scissors to cut
- Can bond plates together if stacked too tightly
- Less elastic; more prone to tearing during application
- Can crack or split with handling
- Higher per-foot cost in long rolls
Where Mycologists Use It
Common applications in agar and culture work
- Sealing inoculated plates after transfer to prevent contamination during incubation.
- Long-term plate storage in the refrigerator without drying out the agar surface.
- Stock culture preservation — sealing master plates that get pulled out repeatedly for transfers.
- Sealing colonized plates for shipment or transport between work areas.
- Wrapping jar lids or other small culture vessels where a flexible secondary seal helps.
One roll typically lasts months even for active hobbyists, and weeks for working production labs.

Let customers speak for us
I was getting alot of contam with northspore boomr bag strait garbage company. Contamination central at northspore almost everything contams. I tried a couple other companies then tried this blackcow. Its black gold Texas T the biggest dummy in the world will get massive flushes with this. The grain bags are awesome too and sterilized right. I went 14/14 on the grain bags. Midwest know what they are doing and even the packaging is next lvl everything double bagged. I only buy from midwest it's worth every cent
It's been several days since the Ecosphere arrived and I set it up, and I'm still amazed at all I got for the price: heater, fan, humidifier, two plug-in timers, two foil trays, and, of course, the five-tier tent with shelves and the plastic cover. Oh, and the LED light strip and the round air filters. It's everything I need right now, and I've started the growing process. It's a crazy good deal for the price. I'm new to mushroom growing, and I'm thrilled that I bought this setup as a start. Just plain wonderful.
Fast and easy colonization! These grain jars showed growth after just 10 days. My previous efforts with the all-in-one bags are taking MUCH longer but also working. Thank you Midwest Grow Kits 🙏
I love the people and the products. The people at MWGK clearly care about the integrity of the community they serve.
The monotub works amazing only had it a couple of weeks and about to have second harvest I used AIO grow bag for first flush and move to tub for second and its great not having to watch 24/7. Thanks Midwest
Four days after mixing grain, Select substrate, and the Midwest horse manure booster - the results speak for themselves.
It has everything you need for a fast, large flush success with fewer moving parts than a standard monotub. It is a surprisingly versatile option for more advanced students. Pic is 5 grain jar at 8 days. GT LM This is where I shop, now.
Rich, perfectly field-wet, sterile and it is perfect for those many varieties that won’t thrive quite as well in Bulk Substrate and Casing Mix, which I’ve seen as best for psilocybes/cyanescens. I’m using it for the first time with Lions Mane and King Trumpets. So far so good, 7 days and primordial and pins are starting to flourish. It drains better and is lighter than MGK’s Bulk Casing and Substrate. Great product.
Love the heater and how even and exact it heats. I set mine to 76 degrees and my room fluctuates from 64-75 and it holds solid at 75 degrees. I used a probe thermometer to double check the substrate level temp and its exactly 1 degree less than the heater setting. Another tip, I only needed to use the round monotub thermometer to check my humidity levels every so often. I would leave a filter disk on that hole instead of the thermometer. The only time it came in handy was after my first flush when humidity started to drop. I was able to use that gauge and check whether I needed to mist. Overall great kit and worth the money!
Ive bought mutiple jars before i came up with my own recipe, every jar produced healthy cultures, even if ones damaged in shipping they replace immediately, highly recommend
Very small chance that you get a contaminate you already had it and you’re either culture spores etc. their stuff is 100% sterile every time 100% of the time everything is viable never had a problem been shopping with them for sometime
It’s very good product and I highly recommend it to everyone.👏👏👏
I love my magnetic stir plate it works great for Liquid culture jars.
My bag had a slow start, but excellent finish. Oak Ridge.
Great product for my cannabis best deal around arrived fast thank you Midwest grow kits definitely will be purchasing again
