What It Covers

  • The five-class solvent framework — a classification that sorts every seaming solvent by solvency strength and evaporation rate, matched to substrate and line speed.
  • Seam defect diagnosis — a step-by-step sequence that starts with the most common root causes and works toward the least common, before changing the solvent.
  • Film-by-film qualification — how each polymer substrate responds to solvent welding, and which classes apply.
  • Mechanical setup — the non-chemistry variables that affect seam quality.

Who It Is For

Converters, plant engineers, quality managers, and procurement professionals working with shrink sleeve seaming — whether running PVC, PETG, PET, or polyolefin, at any line speed.
