Meaning
Mineral oil saturated hydrocarbons and mineral oil aromatic hydrocarbons represent complex mixtures of chemical compounds often found as contaminants in food contact plastics. These compounds originate from the migration of printing inks, lubricants, or recycled paperboard into polymer structures during the manufacturing cycle. Quantitative analysis identifies the presence of these substances through gas chromatography and flame ionization detection methods.
Resin Contamination
Secondary raw material sources often introduce such hydrocarbons into the supply chain through inadequate purification of post-consumer plastics. Virgin resins maintain lower levels of mosh moah due to the controlled nature of petrochemical synthesis compared to collected waste streams. Processors mitigate these risks by sourcing high-purity pellets or implementing functional barriers that block migration pathways within the film structure.
Barrier Performance
Functional layer thickness determines the capability of a structure to block hydrocarbon transmission from external packaging components. Dense polymers like polyethylene terephthalate or specialized barrier resins prevent mosh moah from reaching the edible product housed inside the container. Thin gauges require precise extrusion control because any localized thinning compromises the integrity of the total barrier shield.
Analytical Threshold
Regulatory standards define the limit of these mixtures in migration testing to ensure consumer safety and compliance with international food packaging directives. Laboratories report the sum of carbon chain fractions to establish whether the material passes safety assessments for specific types of food contact. High migration values indicate a failure in material selection or a defect in the sealing process that requires immediate revision of the production strategy.
