Abstract
A biocontainer film enhanced with an abrasion resistant or “cut-proof” substrate. Such substrates can be combined with current biocontainer materials, via various techniques of embedding, coextrusion or laminating, to maintain the cleanliness and low extractables already validated for biotech manufacturing. The substrate of choice may be constructed from materials known to be more resistant to abrasion and sharp razor type cuts or from materials oriented in such a way to prevent puncture to occur. The new substrate must also be flexible to allow for typical folding as demonstrated by current packaging practices. The new substrate may be constructed from materials other than polymers such as metal, glass or carbon or in combination with polymers. A non-constrained pressure test is also disclosed.
