Where to get Long Sellotape Cutting Blade...?

You could use two or three cutting edges from boxes of aluminium kitchen foil.

A 5 pack of cheap carbon steel hacksaw blades? 12" long with little holes in the end to screw them on with? About £3?

Genius...! Why didn't I think of that...!

Make a guillotine out of two sides of thin plywood, the blade can be a piece of aluminium sharpened on a bench grinder.

The aluminium slides down between the plywood sides and chops the bubble wrap.

A short length of bandsaw blade, or a cheap sawblade for a bow saw should work well.

Thanks - could try that too

You hit the nail on the head... A hand,compound mitre saw blade

Angle grinder

Unfortunately, I've found that these bend too easily, and almost make their intended purpose worthwhile. More force, and thicker stuff (bubblewrap) and it'll lead to tears before bedtime.

On (some) boxes of cling-film/aluminium wrap.

Bandsaw blade.

Band saw blade - cut to length, sharpen with angle grinder, fix to batten or something. I'll send you an old one (3\4") if you email me etc

Cellulose Sellotape is a different type of material to polythene bubble wrap. Poly stretches, and its far thicker, and I dont think would be as well suited to a serrated cutting strip. I might try a nice sharp knife blade mounted so it slides along slicing it, some type of guillotine. OTOH maybe someone else has actually done it and really knows.

A 1m hot wire might work well too, with some kind of lightweight clamping mecha.

We had one where I used to work, it was for the film you use with the hot expanding foam system type thingie. The teeth were pretty big and nice and sharp. :-(

If the bandsaw blades are no good I'd try a pack of trade handsaws from Screwfix and break the handles off and then sandwich them before two bits of wood. :-)

gardener's bush-saw blade?

If all these fail, you could train in the ways of the Samurai to the level Master and then use a samurai sword.

Hope that helps :)

These are my thoughts as well. I'd just use a board as guide for the semi-open scissors to slide against. Get the opening right with scissors and you don't need to operate them they just slide through stuff from paper to cloth to poly sheet...

You're right, the blade idea doesn't work.

The bubble wrap is just too stretchy and doesn't break off cleanly like sellotape does...
