Insulating tape damaged

My Insulating tape is damage, where can I get new one, or what can I use?

I am looking forward to getting a solution.

Best regards,

Which tape do you talking about? I do not use tape for printing...

3M makes a high temperature tape rated to 300C.  I bought mine in the US at a local Orchard Supply Hardware.  If you damaged your insulating sheet, you can can use a fire retardant pad plumbers use to sweat copper pipes, and prevent burning surrounding material.  You can find a 1 foot square in the plumbing department.  I cut mine to size and peeled it in half since it was too thick.

I haven't tried it, but have considered just cutting a soda can to the same dimensions and crimping the ends closed.  That might work better than tape.
