Examinationmethods

specific migration (SML)/ NIAS- Screening/ Single substance analyses/ GC- MS- analysis

SML (specific migration limit) analysis of individual substances for compliance evaluation
Quantitative analysis of substances with limits (SML, SML(T), QM, QMA etc.) or non-evaluated substances by gas chromatography (e.g. HS-GC, GC/MS), liquid chromatography (e.g. HPLC/MS), mass spectrometry with inductively coupled plasma (ICP-MS) in food simulants or foodstuffs after migration or (residual) content determination in the material or article

Overall migration acc. Reg. (EU) No 10/2011 standard test conditions (OM 0 - OM 7)
Regulation (EU) No. 10/2011 (PIM)/DIN EN 1186 classical food simulants for all filling goods (no alternative tests like Isooctane testing): A = Ethanol 10 % (v/v), B = Acetic acid 3 % (w/v), C= Ethanol 20 % (v/v), D1 = Ethanol 50 % (v/v), D2 = Vegetable oil, E = poly(2,6-diphenyl-p-phenylene oxide) (Tenax ®)

Damage resp. complaint analyses/ special test methods

Damage analysis/ analysis of complaints
In many cases, it is not immediately obvious which kind of tests are necessary and reasonable for the 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 realization 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 the anomalies ,point in time of recognition, technical information such as material structure, yet present test results are known to be helpful for successfully examination. If available, please send us reference samples, data sheets, specifications.

Mechanical/ technological properties

Dimensions and repeating patterns on pouches, bags etc.

storage test/ accelerated aging in lab drying oven or refrigerator (controlled temperature)
Storage tests with or without filling good for estimating the long-term stability of materials and packages. The storage tests, depending on the requirements, could be carried out in lab drying oven (convection), refrigerator, explosion-protected heating chamber (e.g. solvent-based media,T1- T3 max 105 °C;T 4 max. 70 °C), climate chamber (humidity and temperature controlled, temperature and humidity cycles possible). Please select the appropriate method to avoid unnecessary costs. Tests by this method are common for accelerated assessment of material aging for long-term applications, also in terms of resistance against chemicals, foodstuffs or other filling goods. The assesment looks purely on technical aspects, for the assessment of compliance with food legislation is referred to relevant legal requuirements. Nevbermind, we strongly recommend parallel tests under real storage conditions to validate the meaningfulness of accelerated aging tests. To prepare an offer we need the following information: What type of packaging should be tested (size, filling volume)? How many packages should be stored? Are the packages empty or do they have to be emptied before testing? Which contents are involved (CAS no./ safety data sheet)? How long should the packages be stored? Under what ambient conditions should the packages be stored (temperature, controlled relative humidity)?

Tensile test paper, sealing strength of paper samples
Paper DIN EN ISO 1924-2 determination of tensile strength, stretch at break,TEA (accredited test method) DIN EN 868-4 Annexe C, measuring the seal strength of machine-made bags or sealed samples made of paper

curling or flatness
The curl of sheet materials depends generally on temperature and conditioning state. So multilayer materials produced by usage of materials having different coefficients of thermal expansion or unequal expansion/ shrinkage due to differing hygroscopic tendency may tend to curl caused by a kind of bi-metall effect. In addition to that excessive mechanical stress in the processing of rolls can cause curl.

Compression test on cups, buckets and basins (temperature range - 40 up to + 120 °C)
DIN EN ISO 12048 analogue; on unfilled cups, bowls etc.; (filled packages with extra charge); determination of Fmax with v= 10 mm/min at first buckling of the specimen. Smaller packages (approx max 100 * 100 * 100 mm³) can be testet a temperature range from - 40 to +120° C also (additional charge!).

Unpacking barness of cups (hollow bodies)
Unpacking barness test of cups by examination of the resistance against stacking together at constant load Fmax; determination of the number of cups stacking together.

Material analysis

Microtome section/ cross-sectional image
Cross section of films, moulded forms, sealed seams etc., thickness determination of visible layers included,with reflected or transmitted light microscope (accredited test method).

14Mar2021 Wer kommt eigentlich zum Inno-Talk?

Ein wesentlicher Baustein unser neuen Inno-Talks ist das Networking. Derzeit nutzen wir dafür das Tool Airmeet, arbeiten aber auch mit Hochdruck an eigenen Entwicklungen und Optimierungen, um Anmeldehürden zu vermeiden. Das Feedback der Teilnehmer ist schon nach dem ersten Inno-Talk begeisternd....
