Shrinkfast 998

The propane heat tool is the one item every structural shrink-wrap job depends on, and the Shrinkfast 998 is the long-standing professional standard for wrapping boats, pallets and scaffolding.

Not for: People shrinking small retail products or bundles, who need an I-bar sealer or an electric heat gun, not a propane torch.

Which one fits you

film, tape and vents from one system

Dr. Shrink (brand)

Dr. Shrink sells the film, matching tape, vents and strapping as one compatible marine and construction wrap system.

Not for: Product packagers who need thin centerfold film.

Check before you buy

Structural vs product shrink wrap. Structural wrap (boats, pallets, buildings) uses thick polyethylene film plus a propane heat tool. Product wrap uses thin polyolefin or PVC film plus a sealer and a heat gun or tunnel. The two systems share almost no supplies, so buying from the wrong one is the most common mistake.
Matched consumables. Use shrink-wrap tape and vents designed to bond to shrink film. Ordinary packing tape does not bond to heated polyethylene and lets go in wind.
Venting. Add vents to any enclosed structural wrap that will stay on for a season. Without vents, trapped moisture causes mildew and corrosion under the wrap.

Questions

Is shrink wrap the same as stretch wrap?

No. Stretch wrap clings cold and needs no heat. Shrink wrap must be heated to tighten.
