A vacuum packed, frozen, cooked or non-cooked shrimp pack, in which the shrimp-containing plastic pouch has a center thickness less than its outer, surrounding periphery, with more shrimp contained one above the other at the peripheral edges in comparison to a lesser number at the center in the pack

A vacuum packed, frozen, cooked or non-cooked shrimp pack, in which the shrimp-containing plastic pouch has a center thickness less than its outer, surrounding periphery, with more shrimp contained one above the other at the peripheral edges in comparison to a lesser number at the center in the pack. This produces a relatively even heating or cooking of the shrimp when the frozen pack is placed in a micro-wave for defrosting or cooking. Such a pack can be produced by providing an upwardly curved, rigid form underneath the bottom film layer of the pack in the “form, fill and seal”machine during commercial packing of the product in the sealing station and, if so desired, in the forming and fill stations. The rigid form can be provided by a curvi-linear section (FIG. 4) or a hemispherical section (FIGS. 5A & 5B) which presents a convexly curved surface on its upper side, which causes the bottom layer of the flexible film to be bowed up at its center area and flared downwardly at at least two of its opposed peripheral areas. This causes the shrimp or other highly sensitive food produce to be pushed out from the center during the sealing of the tightly fitting plastic pouch.

A method of vacuum packaging highly heat sensitive, separate pieces of relatively movable food products, such as shrimp or other like seafood or other relatively moveable, fungible food products, comprising the following step(s): (a) packaging the shrimp or other relatively moveable, separate pieces of food products one piece above the other in a micro-waveable food package in which the food product is distributed with a greater number of separate pieces in its surrounding, relatively peripheral areas in comparison to it central area, producing a varying density of food product within the package; and (b) tightly sealing the packaging material about the food product holding it in its varying density distribution for ultimate micro-waveing in such density varying distribution.
