A steam sterilizable pouch is disclosed. The pouch includes a non-woven steam-permeable bottom web. A multi-layer intermediate web is bonded to the bottom web. The multi-layer web is substantially steam impermeable, except for a perforated steam-permeable region. The intermediate web includes top and bottom layers. A steam-impermeable top web is bonded by a first line heat seal to the top layer of the intermediate web. A cavity having a heat sealable access opening is located between the top web and the top layer. At least a portion of the first line heat seal is peelable after steam sterilization of the pouch at 270. degree. F. , the peel strength being from 3/4 to 5 pounds per inch. The bonding of the intermediate web to the bottom web is by a second line heat seal that is located peripherally outside of the perforated steam permeable region of the intermediate web.

A high temperature steam-sterilizable flexible pouch package includes a non-woven barrier web, a perforated plastic intermediate web, and an imperforate plastic upper web. Line heat seals bonding the webs form a cavity into which high temperature sterilizing steam may enter after passing through the barrier and intermediate webs. The line heat seal bonding the upper and intermediate webs is of the delamination failure type. An access opening is provided for insertion of an object to be sterilized into the cavity after which the access opening is sealed, enclosing the object in the cavity. After high temperature steam sterilizing, the package is opened by peeling apart the upper web from the intermediate web which causes a delamination failure of the line heat seal. Preferred materials enable vacuum cycle steam sterilization at a temperature of at least 270. degree. F.

The invention discloses a multiple layer film useful in packaging, and the packages made therefrom. A first layer of the film is a material containing an ester group, a polycarbonate or a polyether block amide copolymer. A second layer of the film is a sealant, preferably polypropylene polymer blended with an elastomeric styrene ethylene butylene styrene copolymer. A third functionally adhesive layer is between the first and second layers. The composition of the third adhesive layer is typically either a polypropylene modified with a carboxy group such as an organic acid or anhydride or a styrene ethylene butylene styrene copolymer.

Novel films are disclosed which contain blends of ethylene-based copolymers or other elastomers with polypropylene and polyethylene. Typical films have two-five layers wherein at least one layer is a blend of high density polyethylene with an ethylene-based copolymer or another elastomer and has additional layers of polypropylene blended with an ethylene-based copolymer or another elastomer.

An access opening is provided for insertion of an object to be sterilized into the cavity after which the access opening is sealed, enclosing the object in the cavity. After sterilizing, the package is opened by peeling apart the upper web from the intermediate web which causes a delamination failure of the line heat seal. Preferred materials enable steam sterilization at temperature of 270. degree. F.
