ABSTRACT:
A plastic trash sack having series of vertical air slots made up of fine perforations on upper portions of both sack walls that break open from stress of compression to allow excess air inside sack to discharge to outside atmosphere. The discharge of air facilitates sack to compact upon its self and flexible trash contents within, further minimizing sack volume and continually maximizing receptacle holding capacity for the duration which compression is generated by weight of other sacks or applied by persons.
