A paperboard carton with improved tear resistance and blanks therefor for packaging a product such as bacon, said carton having an inspection flap for viewing the contents and scoring lines which provide easy opening of the carton. The tear resistance of said carbon is improved by the positioning of the scoring lines which are located such that lines of force initially created by lifting the inspection flap do not intersect a ply-separation area located within the edge section of the top panel.

Carton with inspection flap and easy opening features and blanks therefor

A process for packaging units of food in which the food units are placed on a bottom film and slits made in the film. The film with the food units thereon is passed into an open chamber, the chamber closed, and a vacuum drawn on it followed by back-filling with a substantially oxygen-free gas. The film with the food units thereon and a top film over the units is then subjected to vacuum and the top and the bottom films sealed. Alternately the package may be back-filled with oxygen-free gas prior to being sealed about the food unit. The disclosure includes also the steps of partially sealing food units between top and bottom films in a first chamber, back-filling with a substantially oxygen-free gas, then vacuumizing in a second chamber, and fully sealing the packages in a second chamber, or alternately back-filling with the oxygen-free gas before fully sealing.
