Abstract

Disclosed is a packaging system capable of protecting the freshness and structural integrity of fully-baked pastry shells during shipping and storage. According to the disclosure: individual pastry shells, held in conforming baking pans, are placed in paperboard cartons; at least one stack of cartons is then enclosed by a bag comprised of high polymer film; shock absorbing material is positioned to totally surround the cartons; and a corrugated shipping container is employed to enclose the absorbing material, the bag, and the cartons.

Claims

1. A packaging system for protecting the freshness and structural integrity of a plurality of fully-baked pastry shells during shipping and storage, the system comprising:

at least one stack of paperboard cartons, each carton being an individual point of sale package, each carton containing a fully-baked, unfilled pastry shell, having a moisture content of less than about 4%, having a substantially continuous surface, and containing from about 2% to about 5% glycerol, positioned within a pan such that the combination of the shell and the pan contacts each of the internal walls of the carton to substantially limit the movement of the shell within the carton;

a bag comprised of a high polymer film surrounding the stack of paperboard cartons;

at least one layer of shock absorbing material surrounding the bag; and

a corrugated shipping container enclosing the shock absorbing material.

2. A packaging system according to claim 1 which comprises at least two stacks of paperboard cartons, each stack containing from 4 to 8 cartons.

3. A packaging system according to claim 1 wherein each pan comprises aluminum foil sized such that the pan containing the pastry shell contacts each of the internal walls of the carton to substantially limit movement of the shells within the cartons.

4. A packaging system according to claim 1 wherein the cushioning material comprises a plurality of layers of cellulose wadding.

5. A packaging system according to claim 4 wherein the cushioning material is comprised of two flat sheets folded over the bag;

one sheet extending over the bottom and two side walls of the interior of the shipping container; and

the other sheet extending over the bottom, the other two side walls, and the top of the interior of the shipping container.

6. A packaging system according to claim 1 wherein the bag comprises high density polyethylene.

7. A packaging system according to claim 6 wherein the bag is heat sealed to form a continuous airtight closure.
