PTFE adhesive - serves as
the lower barrier for our hand impulse sealers. Choose the correct
size for your sealer seal length.
Important: You must replace the
PTFE adhesive anytime you change the heating element. The adhesive
serves as a barrier between the heating element and the sealer. When
the heating element has burned through the bottom adhesive and arc'ed on
the sealer's body, the element will prematurely break. This can also
cause damage to the timer. When you replace the adhesive, make sure the
adhesive is 1/4" - 1/2" past the machine on both ends to prevent the
heating element from coming in contact with the sealer's body.
