Abstract
A transparent packaging laminate (10) for use in a container (15) for protecting medical products (18) from oxidation and deterioration as a result of exposure to ultraviolet light. The laminate includes a first transparent film (11) of a polyethylene material laminated with a polyester adhesive (13) to a second transparent film (12) of a polyester material. The transparent polyethylene material has a water vapor transmission rate of less than 20 grams/m.sup.2 /24 hours. The transparent polyester material absorbs ultraviolet light having a wavelength in a range of from 285 to 358 nanometers and has a water vapor transmission rate greater than 20 grams/m.sup.2 /24 hours, whereby the resulting laminate is unexpectedly wrinkle-free after ethylene oxide sterilization. The container comprises the ultraviolet light absorbing laminate and a sheet of spun-bonded olefin material attached to the laminate, which is opaque to ultraviolet light and forms a cavity (17) therebetween with the laminate for containing a medical product therein.
