• a bottom tray comprising sidewalls and a bottom wall to define a cavity to receive the medical device, a flange extending outward from top edges of the sidewalls, the flange comprising an inner flange portion and an outer flange portion disposed outside of the inner flange portion;
• an inner lid adhesively sealed to the inner flange portion at a first sealed region, the first sealed region forming a microbial-resistant, sterile seal between the inner lid and the inner flange portion, the inner lid comprising a sterilizable material that is permeable to a sterilizing gas to allow the medical device to be sterilized when the inner lid is sealed to the bottom tray, the inner lid and the bottom tray forming a microbial-resistant, sterile enclosure for the medical device;
• and
• an outer lid overlying the inner lid and adhesively sealed to the outer flange portion at a second sealed region, the second sealed region forming a microbial-resistant, sterile seal between the outer lid and the outer flange portion, the outer lid comprising a metal foil layer and an environmental member disposed between the metal foil layer and the inner lid,
• wherein a corner portion of the outer lid extends outward beyond a corner of the flange of the bottom tray, whereby, upon application of a withdrawing force to the corner portion of the outer lid, the inner lid and the outer lid are capable of being peeled together from the bottom tray.
