  • Transparent high surface gloss for high printability and streak.
  • Withstand higher temperatures than 1000 0C, however, the sealing (body) of pp packaging (140 0c) – High compared to PE – can cause fire like damage to the external structural film, so often use pp. as the innermost layer.

PVC contains vinylchoride, commonly known as VCM, has the ability to cause cancer (discovered 1970)


PVC packaging has the following disadvantages:
  • Density: 1.4g / cm2 is higher than PE and PP, so it takes a large amount of pVC to get a film area of the same thickness compared to PP or PE.
  • More waterproof, less water than PE, PP resins
  • Brittle, not as flexible as PE, PP, to make flexible PVC used for packaging, it is necessary to add additives.
  • The PVC that has been plasticized by the additive will be denatured and brittle after a period of time.
  • Although the VCM residue has been controlled less than 1ppm, which is a safe level, but in Europe, PVC is still not used for food packaging despite its cheaper price than many other plastics.


  • Use as a shrink film label for bottles, plastic bottles or shrink films for short-circulating foods such as raw meats, fresh vegetables and fruits.
  • In addition, PVC is used to make many household items like products of other industries.
