This bag includes an injection port (photo to the right).  It is identical to bag Type 4-B and bag Type 4-A except that it has a Type T filter.  It is often used in the production of grain spawn and holds about a kilogram of spawn.

This side-gusseted breathable bag gives a sturdy stand-up bag after filling and a strong bottom seal. We manufacture it with equipment we designed and with proprietary additives, Unicorn Bags are pliable at any temperature as well as after sterilization. The bag opening is designed for easy sealing and the bag’s bottom seal can withstand agitation.

Bags are sold in lots of 1,000.
