Claim 0:
1. A method for bundling a group of heat-sensitive products, comprising:
providing a heating oven with a convective heat source and a radiant electromagnetic energy source therein and the group of heat-sensitive products, wherein the group of heat-sensitive products comprises a front side, a back side, a top, a base, a right side, and a left side, and wherein each heat-sensitive product of the group of heat-sensitive products comprises a wall with a thickness;
wrapping the group of heat-sensitive products with a shrink film that comprises an activation temperature and an electromagnetic energy absorbance level forming a wrapped group of heat-sensitive products;
placing the wrapped group of heat-sensitive products inside the heating oven for a predetermined duration of residence time;
exposing the wrapped group of heat-sensitive products to radiant electromagnetic energy for a predetermined duration of exposure time; wherein the electromagnetic energy is localized to an area outside of heat-sensitive areas of the group of heat-sensitive products, wherein the heat-sensitive areas comprise first areas of the heat-sensitive products that are more easily distorted or otherwise damaged or generate more undesirable effects than the rest of the product; and
removing the wrapped group of heat-sensitive products from the heating oven resulting in the wrapped group of heat-sensitive products wherein the wrapped group of heat-sensitive products is robustly bundled according to the Bundle Rigidity Test, described herein, without substantial damage to the heat-sensitive products of the wrapped group of heat-sensitive products.
