- b) adhering by using a water resistant starch the corrugated “B” flute medium to a kraft liner side of a first lamination comprised of a kraft liner laminated to a metallized polyester plastic film serving as a radiant barrier layer,
- c) corrugating a “C” flute medium,
- d) adhering by using a water resistant starch the corrugated “C” flute medium to a kraft liner on one side of a laminated sandwich of a metallized polyester plastic film serving as a radiant barrier layer laminated to and between two kraft liners, the kraft liners being on opposite sides thereof,
- e) adhering by using a water resistant starch the “B” flute medium to the kraft liner on the other side of the laminated sandwich,
- f) simultaneously with step e), adhering by using a water resistant starch the “C” flute medium to a kraft liner side of a second lamination comprised of a kraft liner laminated to a metallized polyester plastic film serving as a radiant barrier layer, and
- g) forming into a regular slotted container with an outside glue flap to maintain the truest inside container dimensions;
- h) packing the container with gel packs to maintain a low temperature for packed contents;
- and
