elixir quality control

The control over the quality of the elixir resin is ensured via rigorous testing and analysis.

elixir PET resin is tested both during manufacture and by secondary post production testing and evaluation at a specialised laboratory.

The elixir laboratory is a certified and registered ISO 9001 facility specialising in PET characterisation.

There are many specific tests which are undertaken to assess the quality of the product. Below we have listed a few of these and the accompanying schematic gives a visual interpretation of the procedure


testing methods

	intinsic viscosity: the IV value is crucial in determining the mechanical properties of the final pre-form or bottle. Click here to view an animation of the testing process
	melting point determination : accurate thermal analysis allows us an insight into the purity and construction of the PET. Click here to view an animation of the testing process
	acetaldehyde (AA) analysis - controlling this harmless organic compound is vital in determining the taste of the packaged beverage. Click here to view an animation of the testing process
	colour measurement - useful in determining whether a polymer has been degraded during manufacture. Click here to view an animation of the testing process
	moisture content - excessive moisture can cause defects in the pre-form and bottle such as haziness, voids and streaks. Click here to view an animation of the testing process
