Description
Our toughest solvent recycling bag. Super heavy duty 4 mil solvent recycling bags sized for the Kresco / ISTpure SR240 and SR240V solvent recyclers and other 64-gallon batch stills. That’s 33% more film than our 3 mil heavy duty bag — built for the shops that are hardest on a liner: heavy pigment and paint solids, flexo and gravure ink sludge, dried coatings, and long high-temperature and vacuum distillation cycles where a thinner bag can soften, stretch, or tear before the cycle ends.
Line the boiler, run your cycle, and lift the residue out in one piece. A bag that holds together means no solids baked onto the boiler wall, no scraping, less downtime between batches, and a still that keeps transferring heat the way it should.
Why go to 4 mil?
- Heavy solids loads — high-pigment paints, primers, inks and adhesives that leave a thick cake behind
- Vacuum stills — the SR240V pulls hard on the liner; extra gauge resists stretching and puncture
- Long cycles and sharp residue — dried coatings and flakes that punch through lighter film
- Fewer failed bags — one torn bag costs more in cleanup time than the difference in bag price
