Película agrícola certificado EN 17033

Blow Film


INZEA® has developed a range of biopolymers specifically designed for blown film extrusion. Our products can be processed on conventional PE and PP extrusion lines and can be adapted to any blown film manufacturing technology, whether for single or multilayer films.

Thanks to their compostability and biobased content, INZEA biopolymers are the ideal material for grocery bags, fruit and vegetable section bags, food packaging and also for agricultural mulch.

Blown film extrusion with INZEA biopolymers

Blown film extrusion is a continuous operation of melting one or more polymers through a circular die to form a hollow tube. The tube expands with air, collapses and finally coils up.

ForINZEA blown extrusion grades, a blowing ratio (BUR) of 1.8-3.0 and a cooling air temperature of less than 20°C is recommended. Single air cooling or internal bubble cooling (IBC) systems can be used.
