Sterilizable flexible peel-seal pouch package |
摘要 |
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 DEG 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.
