Abstract
A polymer film for packaging at least one microorganism culture medium includes at least one layer of polyethylene terephthalate and at least one heat-sealing layer, such as polyethylene. The polymer film has an average water vapour permeability of between 10.0 g/m2×24 hours and 80.0 g/m2×24 hours.
Claims20
A polymer film for packaging at least one microorganism culture medium, said film comprising at least one layer of polyethylene terephthalate and at least one heat-sealing layer, wherein:
- said film has an average water vapour permeability of between 10.0 g/m2×24 hours and 80.0 g/m2×24 hours;
- and
- said film does not have a coating layer including polyvinyl chloride (PVC) and/or polyvinylidene chloride (PVDC) and is obtained directly by extrusion or complexing.
A polymer film for packaging at least one microorganism culture medium, said film comprising at least one layer of polyethylene terephthalate and at least one heat-sealing layer, wherein:
- said film has an average water vapour permeability of between 10.0 g/m2×24 hours and 30.0 g/m2×24 hours;
- and
- said film does not have a coating layer including polyvinyl chloride (PVC) and/or polyvinylidene chloride (PVDC).
A polymer film for packaging at least one microorganism culture medium, said film comprising at least one layer of polyethylene terephthalate and at least one heat-sealing layer, wherein:
- said film has an average water vapour permeability of between 10.0 g/m2×24 hours and 80.0 g/m2×24 hours;
- and
- said film is obtained directly by extrusion or complexing to reduce variability of the water vapour permeability during batch manufacturing.
