3.7 Illustration of the Inventory Phase by an Example 139

PET Bottle

For a deduction of representative packaging specifications, contrary to
cartons, no reference to market data for an average calculation was possible
as access to the necessary data was missing. The multiplicity of preform
and bottle manufacturers makes an estimate of the total market even more
difficult. The selection of PET one-way bottles examined here therefore relates
to bottle types which were used in the year 2005 in Germany and their market
share was regarded as representative in the respective range of application.
Bottle weights and packaging specifications listed in Table 3.8 are based
on information of beverage manufacturers as well as on market knowledge
of companies represented in the project advisory board. The validity of the
selected calculations was verified additionally by test purchases.

were examined. Typically one plastic layer with higher barrier characteristics
