Verification of Supply Chain Certificate Validity and Scope Schedules
Verify certificate status against public scope schedules to ensure product group codes, grammages, and converting sites explicitly cover every delivered batch.
MOSH MOAH Screening
Chemical Assessment
Analytical evaluation of mineral oil hydrocarbon content identifies saturated and aromatic compounds within packaging materials to ensure migration levels remain beneath established safety thresholds for dry or fatty foods. The mosh moah screening process employs liquid chromatography coupled with gas chromatography and flame ionization detection to isolate substances based on their molecular mass and polar properties. Labs conduct this procedure when raw paper fibres undergo recycling, as recovered pulp frequently carries residues from printing inks, adhesives, or machinery lubricants.
High concentrations of these specific hydrocarbons present a risk to human health through leaching into packaged items. Accurate quantification requires solvent extraction techniques adapted for diverse substrate densities, including recycled corrugated board or paperboard. Rigorous calibration of the detector response ensures that results remain consistent across different laboratory environments.
Migration Boundary
Production lines demand precise thresholds for hydrocarbon content to prevent cross contamination in secondary packaging. The analysis determines if the paper stock meets regulatory safety criteria for direct contact or indicates a requirement for a functional barrier layer to mitigate transfer. Converting facilities utilize this data to select coatings or film laminates that block the diffusion of mineral residues into the food matrix.
Any substrate exhibiting values above the designated limit prevents use in sensitive supply chains, necessitating either a shift in sourcing or the inclusion of mineral oil saturated hydrocarbon absorbents within the structural design. Technical teams monitor the consistency of the pulp furnish, as variations in the feedstock composition alter the baseline concentration of these hydrocarbons before any protective layer reaches the surface. Constant surveillance of the input material regulates the quality of the final converted paper goods.
Performance Threshold
Quality management relies on these measurements to validate the integrity of supply chains using secondary fibres. Laboratories perform testing on specific surface areas to calculate the total mass of contaminants per unit of material, establishing a clear link between material composition and consumer exposure risks. Stringent protocols define the operational limits for the testing equipment to minimize signal noise while isolating specific hydrocarbon chain lengths.
Standardizing these analytical steps allows producers to verify if the packaging conforms to industry safety requirements regarding long term stability. Proper screening provides the proof of compliance necessary for market access in regions where hydrocarbon migration represents a primary food safety concern.
