Description
Water quench blown film extrusion allows producing films with
unique mechanical as well as exceptional optical characteristics.
It is especially in the sector of thermoforming and heat-seal
applications that the wet extrusion process offers advantages over
systems using air cooling.
Seven-layer coextrusion water quench blown film line is to run high
barrier film which gets following advantages.
◆ No forming structure
and it is applicable for MDO treatment.
◆ Even better
transparency and gloss than cast film
◆ Better mechanical
property including stiffness, puncture resistance and impact.
◆ The film is soft and
it has well processing performance for thermal forming.
◆ It controls film
edge curve direction when running barrier film in unsymmetrical
structure
◆ It applies modular
concept
â—†Layer ratio control save
resin cost while ensuring the barrier function
◆ The centralized
computer control system controls the temperature, rotating speed,
pressure, blower speed, haul-off, tension, line speed with digital
communication network, displaying and monitoring temperature,
pressure, current, voltage, speed, film meters and other
parameters. The system has the function of automatic alarms and
self-diagnosis
