Abstract

L'invention concerne une feuille de polystyrène comprenant une structure cellulaire présentant au moins deux cellules interconnectées en communication fluidique mutuelle, la feuille de polystyrène se présentant sous la forme d'une barquette. Une ou plusieurs perforations sont pratiquées dans la surface extérieure de la barquette et s'étendent jusque dans la structure cellulaire de la feuille de polystyrène pour communiquer de façon fluide avec les cellules interconnectées. Cet agencement est suffisant pour permettre au gaz de s'échapper de la structure cellulaire afin d'empêcher sensiblement la détérioration de la barquette lors de son exposition à une réduction de la pression ambiante. L'invention concerne également un procédé de production des barquettes et un procédé d'emballage utilisant lesdites barquettes.
