Tenax Migration Testing Parameters for Recycled Packaging Hydrocarbon Verification
Modified solid simulant Tenax TA testing under EN 14338 verifies gas-phase MOSH and MOAH migration from recycled paperboard without false-positive wax interference.
Particle Size 60 80 Mesh
Sieve Specification
Standard laboratory wire cloth defines a specific fraction of granular material when the particle size 60 80 mesh designation governs the distribution. Particles pass through a sieve with 60 openings per linear inch but remain trapped on a sieve with 80 openings per linear inch. This range identifies grains smaller than 250 microns but larger than 180 microns.
Granular Distribution
Manufacturers utilize this specific grading to control the flow rate of coating powders applied to paper substrates. Operators verify the consistency of the dry media by passing a sample through the corresponding stacked sieves under standardized vibration. Material that avoids clumping ensures a uniform finish during high speed production.
Discrepancies in the grain distribution lead to uneven coating thickness or blockages in the applicator nozzles. A tight tolerance within this band prevents defects in the final surface texture of the print stock.
Process Impact
Automated filling systems and high precision coating heads require strict adherence to particle size 60 80 mesh dimensions to maintain mechanical output. Variations outside these boundaries disrupt the mechanical seal on packaging units or compromise the opacity of specialized security coatings. Consistent adherence to this measurement ensures the reliable operation of heavy machinery throughout long production cycles.
