Definitions

  • the present invention relates to improvements in packaging. More specifically the present invention relates to improvements in insulated tamper-proof packaging, and in particular for biodegradable materials.
  • Comestible products are often required to be transported over great distances and for significant length of time where the freshness, viability and security of the product from bacterial and the like deterioration and subsequent safety of the end consumer are of extreme importance and of great value.
  • Freezing of the product for long term storage and transportation at very low temperatures is possible and is used for some products, notably comestibles such as beef and lamb for example.
  • comestibles such as beef and lamb for example.
  • this often results in the destruction of the cellular membranes and is not suitable for such product particularly where the value is primarily in the sale of fresh product which may command higher market value.
  • EPS box or container provides a secure strong and impact resistant container that is thermally insulating. Further, EPS is non-toxic, chemically inert, and non-irritant and rot proof. Fungi and bacteria cannot grow on EPS, it is insoluble in water and is non-hygroscopic.
  • EPS contain the ambient atmosphere in which the product is packaged which may contain aerobic bacteria and substantial level of atmospheric oxygen which may spoil the product, the boxes are also easily opened, for example the product may be examined or interfered with or compromised without traceability during transportation or storage phase. Further the product contained within the EPS box may leak out of the box owing to the poor sealing of the EPS lid.
  • EPS material is gas and water resistant but is not 100% water proof, and will not hold gases; given enough time it will leak.
