Detail of PTFE Tape For Heat Sealer
PTFE Tape for Heat Sealer is a kind of self-adhesive tape, basic material is PTFE coated fabric which provides good release property on the surface. Before applying silicone adhesive on it, we need to etch one side with a special process, then adhesive will be tightly bonded to the basic material. PTFE heat sealing tape is normally cut into narrow width like 1/2″, 3/4″, 1-1/2″, 2″ in order to fit the heating wire of sealers.
The Advantage of PTFE Heat Sealing Tape
Temperature Rating up to 500° F / 260° C
Widely used for packaging, heat molding, laminating, sealing and electrical industries
Ideal for heat sealing, the jumbo roll is good for roller wrap
Excellent dimensional stability, tensile strength and durability
High heat resistant
Superior chemical inert
Outstanding hydrophobic and dielectric properties
