All our foods are individually packaged in heavy duty strength cardboard boxes insulated with a specially designed insulating liner. We also use bubble-wrap and air-filled pillows to keep the goods secure, and ice packs to ensure the goods stay in refrigerated temperatures during transit. We have been doing this successfully for many years now.
Please note, the ice packs (which are literally just frozen filtered water) will thaw gradually during transit - this is how they keep the product cool. Please do not be concerned if you find that some or all of the ice has melted when your parcel arrives.
