I’ve noticed quite a bit of people are interested in the use of cold packs. For non-food items I suggest foam brick cold packs. The PolarPack products I have used so far have the following advantages:
· They retain their shape so shipments don’t shift around when the package starts to thaw.
· They performed quite well in a study that was done to compare methods of shipment.
· They do not leak or dampen the materials that are being shipped.
· They are available in a selection of sizes to fit whatever you plan on shipping.
