A container for a food product includes a wrapper which surrounds a frame. The container can be any polygonal shape which is defined by the shape of the frame. The wrapper forms a top of the container which has an access opening. A sealing cover is adhesively sealed to the top around the opening. The sealing cover is operable to expose the access opening and reclosable against the top to seal the access opening. The sealing cover, adhesive and top surface are optimized to provide sealing characteristics of sufficiently resealing frequency, relatively low noise level during unsealing and desirable peel forces to separate the seal between the sealing cover and the top.
