Abstract
Sealed packages of foodstuffs which are biological materials, particularly fruit, are vented by a temperature-sensitive control unit. The control unit covers an aperture in a wall of the package. The control unit includes a barrier member which is secured over the aperture by a layer of temperature sensitive adhesive, and a force member which lifts the barrier member away from the aperture when an increase in temperature weakens the adhesive. The force member is preferably elastically deformed.
