Ecoflex - Processing
Ecoflex can be processed by conventional LDPE equipment for inflation molding or T-die molding. Printing and heat sealing can also be done using LDPE processors.
Molding Equipment Ecoflex can be molded using standard LDPE and HDPE extrusion equipment. The die gap of the spiral die should be about 0.8 - 2.5 mm (ideally about 1 -1.5 mm).
The flow rate should be 1:2 or more and 1:3.5 for wrap film.
Use equipment suitable for a film with soft edge trimming and that is highly elastic.
MoldingEcoflex - Processing

Purge sufficiently with MFR4-5 for LDPE prior to molding.
Perform purging at 140 -160°C which is the processing temperature for Ecoflex.
Set the chill-roll temperature at 20°C or less.
When slitting the film, use a titanium coated blade as far as possible.
Set the tension winder for the film at the lowest level.
Repelletizing is possible using a uniaxial or biaxial underwater cut extruder
PrintingUse an alcohol-based ink.
The film should be subjected to Corona processing prior to printing.
Set the drying temperature below that for LDPE.
Heat SealingSealing can be done using a LDPE heat sealing line.
Set sealing-temperature slightly lower than that for LDPE.
The sealing conditions greatly affect seal pressure and seal strength.
Because Ecoflex is a polar polymer, ultrasonic wave welding and high frequency wave welding can be done.
