Which plastic
is suitable for your bottle?

PET Power never stops working on new packaging solutions with new plastics. Even though standard PET is used mainly for bottles and containers, there are more and more other applications with specific materials such as Pharmacopoeia PET for Pharma applications, the use of PCR (Post Consumer Recycle PET) or BioPET for a more sustainable choice of material.

Good protection

A precondition for plastics is, of course, a good protection of the product during its shelf life. In addition, chemical resistance and compatibility of the product with the material is important. At PET Power, all materials have Food Grade certification. We make sure that the materials used can always be traced back to their origin. PET Power closely follows developments in this area. Below are the main feedstocks.

PET

PET stands for Polyethylene Terephthalate. This plastic is received at PET Power in the form of granules. What are the advantages of PET for consumers, producers and the processing industry?

  • It is clear and transparent.
  • It is shiny.
  • It is unbreakable.
  • It has good barrier properties.
  • It provides a stable quality, even with subsequent uses.
  • It is 100% recyclable.
  • It is suitable for various forms of decoration, including printing, labelling and sleeving.
  • It can be easily produced in wide range of colours.
  • Many end shapes are possible because of the high degree of stretching.

PET barrier
properties

PET is a material with good barrier properties for many food, medical and cosmetic products. In most cases, it offers sufficient protection during the required shelf life. A number of products require extra protection against, for example, UV light or oxygen. For this, PET Power offers different solutions.

Barrier additives

Barrier additives are liquids or gases that can be added to a product without affecting the product.

Gas barriers

All plastics have a certain degree of gas permeability. An additive with the effect of an oxygen barrier can be added to products that are sensitive to the effects of oxygen. This will extend the shelf life of the product.
Another possibility is a water vapour barrier. The water vapour barrier can be increased by applying a coating on the inside (e.g. an SiOx Coating). There are also ongoing developments with nano additives.

UV protection

A third possibility is to provide a PET bottle or container with extra UV protection. There are types that capture different wavelengths in the UV range. For example, UV protection is added to herbs and spices to protect the colour of the product.
