The PET film cutting process involves converting
PET film,
a raw material used in the production
of biosensors, from
a roll state into a sheet form
suitable for processing equipment.

The annealing process is for contracting
cut films.
It contracts PET films before printing
and forming
to prevent further contraction in
later processes.

The Press Punching process involves injecting
the
structure and sensor samples for assembly of
each
layer into heat-treated film or PSA, forming
an airflow
channel to control the speed, and machining
the
shape that determines the sensor printing position.
