Packaging milk is challenging because the product is destroy easily by light, microbes and air. Producing top quality, safe liquid dairy products requires the right combination. Dry decontaminated PET bottles have helped dairy overcome this problems in an environmentally-friendly way. Unlike wet aseptic technology, the dry preform decontamination technology does not require chemicals or hot water to rinse the bottle.
PET bottles are already used by many dairy companies around the world because of its excellent barrier material properties which have extended shelf life. PET ensures milk-based beverages retain their fresh taste, vitamin content, texture and colour from production to distribution by preventing microorganism growth and alternations caused by the effects of light, oxygen and temperature.
Transparent PET is used for fresh and flavored milk distributed via cold chain as well as UHT flavored liquid dairy products, while opaque PET is used for UHT milk at ambient temperatures. PET is also lighter weight compared to HDPE volume equivalent bottles, offering low carbon footprint, as well as being 100% recyclable with the ability to incorporate recycled PET content..
The main requirements of dairy PET bottles are:
- Light barrier
- Oxygen barrier
- Long shelf life
- Light weight
- High tolerance to acidity
