Shrink Sleeve Seaming is an independent technical resource for the shrink sleeve converting industry.
This site is not affiliated with any solvent manufacturer, film supplier, or equipment maker. No product is recommended by brand, no supplier is endorsed, and no content is sponsored.
Why This Site Exists
The shrink sleeve converting industry lacks a neutral, technically rigorous resource for seam diagnostics. Solvent suppliers publish data sheets but do not explain when a competitor’s product is the better choice. Equipment manufacturers document their machines but not the process chemistry. Film suppliers specify shrink properties but not seaming compatibility across solvent classes. The result is that converters troubleshoot seam failures by trial and error, changing solvents and settings until something works — or until they call a supplier who recommends their own product.
This site fills that gap with a structured, vendor-neutral framework.
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.
