It is used to temporarily fix the template to the material when doing router processing. It is convenient because it can peel without adequate adhesive strength and glue residue at all. Price is also attractive.
I cut off the policy and paste them together to make a kite (parafoil kite). For ordinary double-sided tape, the bonding is weak and it is peeling off immediately. I bought it because it was that this tape has twice the adhesive strength.
