Material selection for packaging

October 3, 2022

A wide variety of materials are used for packaging, which have different suitabilities and strengths/weaknesses. Here is an excerpt of the advantages/disadvantages and properties of various packaging materials:


LD-PE: Low density polyethylene

  • Very flexible for foils and bottles
  • Well formable with low hardness
  • Good chemical resistance
  • Poor resistance to organic solvents
  • Recyclable

HD-PE: Polyethylene with higher density

  • Better resistance to chemicals than LD-PE
  • Well malleable
  • Use up to approx. 100 degrees -large areas of application for food, cosmetics, chemicals and technical blow-moulded parts
  • Recyclable

PET and rPETPolyethylene terephthalate (without/with recycled content)

  • Transparent
  • Dimensionally stable, good strength
  • Used mainly for food, but also cosmetics etc.
  • Good resistance to aqueous and acidic fillers
  • At high temperatures "HOTFILL" options
  • Recyclable

PP: Polypropylene

  • High chemical resistance
  • High strength and rigidity with low weight
  • Well formable, ideal for injection moulding processes
  • Heat resistant and therefore well suited for packaging to be used in microwaves
  • Resistant to UV radiation and therefore often used in outdoor applications
  • Often used for food packaging, medical devices, textile fibres and automotive components
  • Recyclable, but recycling rate often lower than other plastics due to the variety of additives used in different PP products.

Natural substance based materials


  • 100% recyclable
  • Solid and unbreakable
  • Stainless
  • Diffusion-proof
  • Good conductivity for cold and heat
  • Good availability
  • 3x lighter than steel
  • 4x lighter than glass
  • Well malleable


  • Transparency
  • Natural raw materials
  • Tasteless and gas-tight
  • Tolerates high temperatures
  • Can be combined with many other materials without interactions
  • Dimensionally stable
  • High recycling rate


  • Starting material high purity alumina with high aluminium oxide content
  • Waterproof even without glaze
  • High temperature resistance
  • Resistance to acids, aqueous alkalis and salt
  • Use also as a building material
