Default Bags for bagging

Does anyone have a source for very large bags that can be used for bagging? Or has anyone tried making their own? I need to bag an 80 inch mold. Putting stretchlon over the opening of the mold and pulling a vacuum did not work well...to many leaks since the mold was not designed from the start to be vacuumed.
thanks
Glenn

I've used 1 mil Visqueen from Home Depot. Fold it in half then use some Rope Caulking to seal the edges together. It worked on some smaller molds. Should work on a large one.

Similar to me. 3 mill and the cheapest caulk I can buy. Works great.

I roll plumber's putty into a string and use it to seal edges. Works great and allows bag reuse. Not messy at all

I'll Third the use of 1 to 3 mil plastic and chalk. The only other process I use with these is I wipe down the areas where the chalking is placed (i.e. around the outer edges) with grease and silicone remover. Like what an auto painter would use. I seem to get fewer small air leaks when I remember to wipe the plastic down.

Good luck

Try the plastic "heat shrink shroud " that is used for industrial pallet covering. See pics.
It is a contineous plastic sleeve (tube) on a roll and you cut off the correct length and pull it over the pallet, then heat shrink it. They come in various thicknesses from 20 - 150 micron.

You probably want to go for the thinner gauge i.e.30 micron or so. Insert your piece, seal off both ends and Bob's your uncle......
