Centraal Instituut voor Voedingsonderzoek TNO TNO Voeding Publication year 1997 Abstract Absorption aspects of flavours and chemicals are important quality criteria when plastic bottles are reused or recycled. In the present study absorption of methanol and toluene by polyester-based bottles (PET and PEN) was studied at different temperatures in the range 20-40°C for a period of 16 weeks with two different ways of exposure: one-sided and two-sided. Saturation levels were not reached in such a period of storage. However, absorption levels are affected by temperature. An increase in temperature causes an increase in absorption level. Also, the polarity and size of the chemicals, the composition of the plastic (PET and/or PEN) and the crystallinity of the specimens influences absorption. The results did not show whether two-sided exposure is representative of the one-sided situation. © 1997 John Wiley & Sons, Ltd.
