How We Create a Custom Solution for You

For 30 years, Unicorn Bags has been manufacturing and supplying breathable polyethylene bags for a wide variety of industries – beginning with fungi growth and the farming industry but now also serving other uses like bioinsecticides, sterilization, artificial meat, and pharmaceuticals.

Our bags create a biological growth environment with an individually controlled environment in each bag that maximizes growth and yield while reducing your costs. With over 30 years in the bag business, our products are time-tested. They can be trusted even for sensitive and sterile applications like biomedical needs.

Unicorn bags can fit custom requirements for your needs. They can aid in many biological applications, including solid-state fermentation, incubation, and power drying. We can manufacture them for you in nearly any volume. Each bag contains a filter mechanism that lets the exchange of carbon dioxide, oxygen, and nitrogen be customized as well. Our bags are built to withstand high temperatures, so they are perfect for applications that need to remain sterile from start to finish.

At Unicorn Bags, we’re engineers at heart. That’s why we can design the perfect bag and exchange filter for any custom application you need, with ease.
