Do you need clear autoclavable bags for mushroom cultivation and spawn production?

If so . . .

  • You want a breatheable bag that will not harden or have pin holes, coming out of an autoclave.
  • You want a mycobag that does not wrinkle or loose its shape when heated.
  • You want a polypropylene (PP) bag that is designed for mushroom cultivation

You want Unicorn bags!

Unicorn Mushroom and Spawn Bags

  • Our autoclaveable bags stay soft and easy to seal after heat treatment in an autoclave for six hours at 262°F(125°C).
  • Our mycobags can be any size and length, with as many filters as you want, where you need them.
  • Our breatheable bags provide gas exchange, but exclude water vapor, so your spawn does not dehydrate.
  • Our mushroom bags provide a perfect environment for fungi growth. Because we produce our own filters, gas transmission rates can be adjusted to suit your needs.
  • Our bags can be used for fungi as well as nematode production for bio-control of insects.

Customized Breatheable Bags

UNICORN provides free development to create a microvented bag for your application. We give our clients the best service and products of consistent, excellent quality with an unmatched price.
