TRANSCRIPT
Our Microsacs have many advantages, the most important one is their perfectly distributed gas exchange. This makes them the most advanced breathing bags on the market.

The Polypropylene (PP) Microsacs
The autoclavable PP Microsacs are equipped with a revolutionary depth filtration system that allows air flow, but blocks contamination. The core of every filter is a double row of tiny filter plugs. The number of filter strips and therefore the level of gas exchange depends on the application: mother spawn, spawn, substrate, etc. As opposed to conventional spawn and substrate bags that use ‘surface’ or ‘membrane’ filtration (based on microperforation), Microsac filters are much like a small-scale HEPA filter system: they are composedof hydrophobic, randomly arranged fibers which trap microorganisms. This allows a fluent gas exchange without creating a dry-out zone below the filters, while still forming a firm barrier against contaminants.

The Microsac's double filter system:
Autoclavable: the bags are guaranteed to endure temperatures up to 123°C – 253°F, making them autoclave proof.
No dry-out zones: contact between filter and substrate is limited, minimizing substrate dehydration under the filter zone.
Flexibility: the length of the bags and the distribution of the filters are adapted to the application and desired gas exchange rate.
Physical strength: the Microsacs are subjected to rigorous tests to ensure that the bags remain strong after heat treatment and physical handling.
Development: the Microsacs are constantly tested and improved in cooperation with our sister company Mycelia, ensuring that our products meet large production demand and automation standards.
Transparency: the characteristics of the plastic film, in combination with the narrow filter strips ensure optimal visual quality control of the bag’s content.
No patches: the filter strips cover the whole length of the bag, optimizing gas exchange and gas distribution.

Advantages of the Polyethylene Microsac
Polyethylene (PE) Microsacs are gamma-irradiated and are not autoclavable. Mostly used in bulk systems, they are in many ways similar to other PE bags but with the advantage of reduced substrate dehydration in the zone below the filters. This is the key to their success and a technological advancement.
We keep the contact surface between the filter and the substrate as small as possible by putting an microperforated plastic film barrier between substrate and filter, without limiting the gas exchange or filtration capacities. We offer Tyvek® filters, multi-component filters and hydrophobic non woven filters.
