Examinationmethods

Compliance work

Conformity Status
The conformity status is a summing up and evaluation of the available information concerning food regulatory assessment of the specified article. It identifies, where required, open issues of compliance work.

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

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 (OML), Sensory analysis, colour fastness, microbiology

overall migration acc. Reg. (EU) No 10/2011 standardized testing conditions (OM1- OM7)
Regulation (EU) No. 10/ 2011 (PIM)/ DIN EN 1186 classical food simulants (not 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), D 2= 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

Determination of thickness of plastic films, aluminium foils, plane multilayer-materials and sheets
determination by mechanical scanning (accredited test method)

Dimensions and repeating patterns of pouches, sacks etc.
Dimensions like width, length, side gusset depth, bags, reels, packages with calibrated metal measuring stick, n=5

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)?

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.

penetrability of fat/ fat- proof test
Testing of paper, coated paper or plastic films with pigmented palm kernel fat. The sample is covered on the test surface with the test fat and then the glass pane and, if necessary, additional weights are placed on top.At the end of the exposure time, the grease spots up to 1 mm in size, visible to the naked eye on the display paper within the defined test area, are evaluated. If only grease spots up to 1,0 mm are observed, the test is considered to have been passed; in the case of grease spots larger than 1,0 mm, the test has to be performed with a more moderate test condition (a "poorer" grease permeability group).

weathering test/ light fastness- exposure to laboratory light sources or artificial weathering/UV- test
DIN EN ISO 4892-2; with filtered xenon arc lamp, sample area max. 240 x 400 mm²); with water sprinkling (water spray) or dry. Also possible is the determination of light fastness, e.g. from printink inks or coloured materials, acc. DIN ISO 12040 bluescale (wool standard)/ fastness level 1-8.

Blocking test/ blocking strength
Test of the blocking tendency of plane packaging materials, in dependence of temperature T [°C], pressure p [MPa] and time t [h]. The evaluation is carried out either by manual test or by determination of blocking force Fmax [N] by shear test with tensile tester. If the sample should by tested under several test conditions separately, please create multiple tests for each test parameter setting.

Material analysis

Microtome section
cross section of films, moulded forms, sealed seams, etc. incl. thickness determination of visible layers with reflected or transmitted light microscope (accredited test method)

optical tests

gloss
Reflectometer value for the determination of the gloss unit. The measuring angle depends on the surface of the sample (measuring angle: high glossy: 20°, medium glossy 60°, matte:85°).

permeation

Oxygen transmission rate (OTR) of plastic films, laminates, coated papers, Alufoils, etc.
ISO 15105-2, ASTM D3985, ASTM F1927, DIN 53380-3;coulombmetric method (Mocon)
