Examinationmethods



Heavy metals / metals
Elements according to the Packaging Directive 94/62 / EC (lead, cadmium, total chromium, mercury), EDQM Publication: Metals and alloys in food contact materials or metals in accordance with Annex II to Regulation (EU) No 10/2011





Damage analysis/examination of complaints
In many cases, it is not immediately obvious which kind of tests are necessary and reasonable for clarification. Furthermore, test results which are available in short time are often helpful for further decisions. Our “diagnostic concept” provides the agreement of a limited budget (normally 700,- up to 1.000,- Euro) for the screening and evaluation of information already available as well as the realisation and assessment of first tests according to an agreed schedule. The result is a more detailed view of the damage, possible solutions and indications for additional and reasonable investigations and researches are given. You will receive first reliable test results and an appropriate documentation of the current situation at short notice and at a fixed price. Information on the frequency of damage, time of detection, technical information such as material structure or test results already known are helpful for a successful processing as experience has shown. If available, please send us reference samples, data sheets, specifications.





tensile test films and laminates (temperature range -40 to +120 °C)
Determination of: secant modulus, tensile strength, elongation at break (accredited test method)





Film construction/material characterisation - Analysis package at a fixed price
Qualitative characterisation of plastic films, laminates and plastic products concerning layer construction and basic materials, excepting adhesives, tie layers, inorganic coatings, e.g. metallisations. Methods: DSC screening (- 20 up to 300 °C/2 heating runs) of the material as received, microtome cut to determine and display visible layers and layer thicknesses, determination of the material class of the individual layers with FTIR spectroscopy; Beilstein test for presence of chlorine. Additional tests available by arrangement.





Haze/transparency
Method for quantification of the optical properties of transparent or translucent materials (not coulored opaque or metallized). The test method describes the hazing of a film caused by light scattering. A low haze value characterizes a low turbidity equivalent to a good visibility of details of filling goods or labels lying behind or under the film. By increasing the haze value, the "frosted glass effect" increases, i.e. details such as labels are ultimately only recognisable when in direct contact with the film surface. ASTM D 1003 = calibration without compensation port, DIN ISO 13468 = calibration with compensation port. The measured values differ slightly, but the measurements are basically carried out according to the same principle.





Oxygen transmission rate (OTR) of plastic films, laminates, coated papers, Alufoils, etc.
Coulombmetric (oxygen specific) carrier gas method Method (Ametek/ Mocon). Usually deviating from the standard as a double determination
