Materials in contact with food products

Food contact internal coatings

In recent years, a special attention has been paid to the materials and chemicals used to produce food contact materials (FCMs).

Research is constantly underway to improve the practicality and safety of internal coatings and food contact materials to protect consumers. The Article 3 of the European Regulation 1935/2004 states that “any material or article intended to come into direct or indirect contact with food shall […] not transfer its constituents into food in quantities which might endanger human health”. This regulation applies to all substances that can migrate from FCMs – starting substances used to manufacture FCMs, as well as so-called non-intentionally added substances (NIAS).

Although EU legislation permits the presence of NIAS in FCMs, a risk assessment involving the identification and characterization of molecules migrating from the material, as well as an assessment of exposure levels, is required. This year, the European Commission re-evaluated current EU legislation on FCMs and concluded that there are “[…] potential weaknesses in the current approach to regulating FCMs”. One of the issues outlined has to do with the identification of NIAS. The problem with NIAS is that even though awareness of the topic has increased, and some studies have been done, not many molecules have yet been identified, making it impossible to accurately assess the risk, if any.

LEREM’s expertise

LEREM supports its adherents and metal packaging manufacturers who want to be proactive and ensure the safety of their materials, and offers to conduct NIAS studies (identification, semi-/quantification) using high-resolution mass spectrometry techniques. Thanks to the collaboration with LABERCA, the PhD in analytical chemistry engaged at LEREM has access to the LABERCA analytical platform, consisting of 18 different instruments. The identification of unknown substances in food contact materials carried out by LEREM will allow manufacturers to anticipate the compliance of the materials used in the packaging they will provide with future regulatory changes.

General information on impedancemetry

IMPEDANCEMETRY IS A SCIENCE

A brief history of impedancemetry

The first tests relating to impedancemetry date back to Georg Simon OHM (1788-1854), a famous physicist, who established the fundamental relationships between current, voltage and electrical resistance. This science has become popular in recent years, particularly in the medical or paramedical fields. However, it should be noted that this science has been implemented in packaging studies since the 80’s. LEREM, for its part, has been practicing these studies since early 90’s.

Imagine that you can materialize a set of elements through a mathematical model and that these elements can give you physical quantities that you can study in absolute way but also in a relative way. For example, how they evolve over time…

This is what happens with modern person scales, which can read your muscle mass index in addition to your fat mass index, or even from one measurement to another can read how your diet changes your muscle mass…

It is one of many examples of impedance measurement applications. The popularized results of these measurements have gone through mathematical modelling. The mathematical models were calibrated based on the results of measurements of very weak and very precise electrical signals at different frequencies. These results were then used to represent your body in an equivalent electrical model of an RLC circuit (resistive, inductive, capacitive).

Very weak electric power, without any danger, cross your body through the feet and hands or through the measuring points which are connected to your body. You now know the basic principle of impedance measurements works.

USAGE IN OUR FIELD

How can we now apply this science to metal packaging?

It will be done the same way as the bathroom scale, by applying weak electrical signals of great precision at different frequencies to the packaging.

We will seek, depending on the results, to create an equivalent RLC model. We will not try to find the packaging muscle mass but try to find a combination of things. That combination is made of internal coating, substrate and filled formula that present a mathematical model showing a high resistance and a very low capacity. What’s more, the measurements will be repeated at regular intervals so it can confirm, or not the stability of the results over time.

For example, it will thus be possible over a period of 4 weeks to reliably confirm that a combination of varnish, coated on a metallic substrate with a formulation is not stable and therefore possible to anticipate bad storage test results (or compatibility)

These measurements can only be applied if the packaged formula is sufficiently conductive. Certain formulas are not conductive enough and therefore do not allow studies by impedancemetry.

Evaluating the conductivity of formulas can be done easily by using a conductivity meter. Weak signal generators called potentiostat are also intended to go into safety mode if the formula is not compatible with the means of measurement. Note that these studies cannot replace storage compatibility studies. This is a reliable method of knowing more quickly what will not be compatible at the end. This is not a substitute for storage compatibility testing. 

In addition, equipment’s and systems for processing measurements have evolved. Regarding this point, LEREM will be equipped with brand new state of the art equipment from December 2021. It will be covered in a future article.

With more than thirty years’ experience in this field and equipped with state-of-the-art equipment, LEREM remains at your disposal to carry out compatibility studies containing content using impedancemetry.

Studies on aerosol dispensers

Aerosol dispensers

Working with the primary goal of preventing technical problems with new and existing products to ensure the safety of the aerosol dispensers industry.

Aerosol dispensers are the most technical packaging available.  

All the technical details that need to be controlled, in a very large industrial supply chain, must be realised so that, in the end, users can simply press the actuator of an aerosol can and the product is stored and dispensed correctly. 

First, it is necessary to ensure that the aerosol dispenser as a form of packaging is perfectly safe and remains stable over time. Stability of the packaged formula and stability of the integrity of the packaging. For cosmetic products, we often talk about guaranteeing a product for a period of 3 years.

Second, all of this must be guaranteed on a mass production scale. It is estimated that in 2019, 15.5 billion aerosol dispensers were produced worldwide, of which 5.5 billion were produced in Europe. 

Composition of an aerosol dispenser

To make an aerosol dispenser, you need to master a formula, a propellant gas, a can, a valve, an actuator.

It is also necessary to master the filling process, the sealing parameters, i.e. the valve-Can assembly, the valve gasket compression and the Clinching specification, not forgetting all the filling parameters.

All of this works thanks to defined specifications, norms and standards, but also thanks to specifications safety margins that this industry has set for itself for decades.

There are not many places of expertise able to synthesise all these constraints. LEREM tries to do this as well as possible, thanks to the means at its disposal.

These various means are :

  • Testing or stressing 
  • Filling 
  • Accelerated ageing tests by impedance measurement
  • Storage chambers from 0 to 50°C
  • Standard or customised flammability testing facilities for comparison purposes.
  • Virtually all the precision measurement equipment required for aerosol dispensers’ assessments : 
    • Weight +/- 0.003g
    • Pressure +/- 0.01 bar
    • Temperature +/- 1°C
    • Dimensional +/- 0,01 mm
    • All the adapted cutting equipment
    • The possibility to carry out resin studies 
    • Software for measuring crimping dimensions
    • Vision system to observe details of valve-housing assemblies.
    • Spray pattern measurement
    • Clogging tests
    • Laser particle size measurement of spray particles – Malvern Spraytech 2000. 
  • By the fact that LEREM has a recognised level of expertise and years of experience in this field. 
  • Its knowledge of aerosol dispensers’ industry supply chain and its network within this industry.
  • Its close relationship with CFA: French Aerosol Association and their agreement established in 2021 for the next few years. 
  • By the fact that it is an association of public utility, which guarantees its discretion, objectivity, and independence. 

More details about this subject on the dedicated page.

LEREM represents the industry and participates to fundamental studies 

  • The ECORBIO project, which aims to study the corrosion behaviour of piping with heat transfer fluids for the biorefinery circuits of the future using impedance measurement. In conjunction with INERIS, UTC, CETIM, UPJV.
  • MPE (Metal packaging Europe) working group and the compatibility studies contained in the passivation processes for tinplate, which by 2027 should make it possible to use only chromium VI-free passivated tinplate. In the field of aerosol dispensers, this concerns tinplate can and valve mounting cups.
  • The GDA (Gesamtverband der Aluminiumindustrie) supply chain meeting and the many questions raised by the use of alternative coatings to phenolic epoxy coatings. In the field of aerosol dispensers, this concerns aluminium aerosol cans. 
  • Various in-depth studies on existing aerosol dispensers’ flammability results, some of them linked to INERIS, which tend towards new gases development. 
  • The OLIGO project – a very recent ANR study on the NIAS for new internal coating generation in conjunction with LABERCA and INRAE.
  • Standards at national level at AFNOR (Commission de Normalisation AFNOR/H08F CN8 Emballages), at European level CEN (TC261/SC5 emballage métallique), at international level ISO TC52 (light gauge metal containers).
  • Accreditation of LEREM by the Ministry of Ecological Transition (DGPR) with regard to transport of hazardous materials.
