55-gallon drum liners are useful for transporting debris and loose-fill insulation in an attic. They may be collapsed as needed to pass through an opening, yet are self-supporting at a thickness of thirty mils.
There are many uses including painting or plaster prep, where major debris is collected on a sheet, and the loaded sheet is easily shaken out in the drum liner.
I buy them from:
77 Industrial Park Rd.
Plymouth, MA 02360
They are 30 mil thickness, Product Code 5530/34.25-G4.
I made a first purchase as a case of ten, with cost and weight breakdown thus:
Containers weighing 39.3 lb, plus box, 45 lb gross.
Charged $118.70 plus $92.91 FedEx freight, $211.61 total.
Use a drum liner too, in compressing and dragging batts through tight spaces in an attic.
