Abstract
A film for manufacturing a pouch includes a contact layer including (A) a copolymer of ethylene and α-olefin having a density in the range of 0.870 g/cm3 to 0.910 g/cm3, alone or in mixture with (B) a polyolefin having a density in the range of 0.910 g/cm3 to 0.940 g/cm3, the contact layer including less than 0.10 wt %, preferably less than 0.07 wt %, of additives able to release a degradation compound further to gamma irradiation in the range of 25 kGy-50 kGy that can slow down or delay cellular growth. The process for manufacturing such a film, as well as the single-use pouch manufactured from that film are also described.
Claims20
A film for manufacturing a pouch, said film comprising:
- a contact layer comprising (A) a copolymer of ethylene and α-olefin having a density in the range of 0.870 g/cm3 to 0.905 g/cm3, in mixture with (B) a homopolymer of ethylene having a density in the range of 0.910 g/cm3 to 0.940 g/cm3, said contact layer comprising less than 0.10 wt % of additives able to release a degradation compound further to gamma irradiation in the range of 25 kGy-50 kGy, that can slow down or delay cellular growth,
- wherein the film is a sterilized film and is configured to be manufactured as the pouch,
- wherein an amount of anti-block in the contact layer is less than or equal to 2 wt %,
- wherein the contact layer is sealable on itself, and
- wherein the contact layer is configured to contact with a biopharmaceutical product without causing degradation of the biopharmaceutical product.
