Filters and perforations

UNICORN manufactures its own filters.

The customer can choose between various types of filters for their bags, according to their needs of gas exchange, type of substrate formulation, the use to which the bag will be destined, etc. These parameters will define the filter requirements.

  • The main function of the Filter is to maintain an adequate and clean atmosphere inside the bag.
  • The second function of the Filter is to provide an adequate gas exchange, which is determined by the percentage of pores per given surface and the size of the pores.

UNICORN manufactures filters that are not affected by the heat of sterilization, keeping the pore size intact.

The filters are thermally fixed to the bags, no adhesives are used.

TYPES OF FILTER: Filter A, Filter B, Filter T, Filter TV
