1) AA (Acetaldehyde) is a chemical component which naturally exists in the PET raw-material with the maximum proportion of 1% and this proportion increase throughout the processing process. If a lot of AA is formed in the structure of PET package, a bad smell occurs and disturbs the user; this occasion is a problem which is frequently observed in the use of natural mineral water. They are special additives which are appropriate for food and they are employed to keep the levels of AA amounts at a definite amount in PET packages through preventing this occasion with AA Blockers.
2) In order to help to the protection of the materials with UV sensitivity in pet packages, the UV blockers are employed for this purpose and it was aimed to minimize the UV based decaying of the materials to be put in the packages and their interaction.
3) In order to save energy during the process of heating employed for the production of bottles from preform, preforms with special additives are produced and energy conservation up to 20% is obtained in the heating energy.
