Advanced yet Easy-to-Use Blown Film Extrusion Technology – Key to Eco-friendly Packaging

Whether monolayer extruders or co-extrusion machines, POLYSTAR blown film machines have gained the fame of stable operation among our customers in more than 110 countries. We witness our customers producing films for their specific product requirements smoothly due to the precision in the screw and die head designs; carefully testing parameters like temperature, heating/cooling rates, film width, thickness, and tension. This operation stability not only saves from defective scraps but also saves energy and labor hours.

PE derivatives are often used in blown film extrusion. These materials are highly recyclable and producers often blend PE, HDPE, LDPE, and LLDPE with each other as well as with the bioplastics, CaCO3, recycled plastics, and color or filler masterbatches.

POLYSTAR designs its screws for excellent blending and melting performance for these various tasks of film producers. As a result, the producers will be more flexible to optimize the materials desired and use more recycled plastics, while they will be less dependent on virgin polymers.

Before deciding to purchase a blown film machine, it can be advantageous for you to contact our sales specialists, to get suggestions on what types of machines are more feasible for your production. Because POLYSTAR focuses on highly customizable blown film extruders to save you energy, space, and material.

For instance, twin-head blown film extruders produce two different widths & thicknesses of film rolls at the same time on different winders, while using only one extruder. The optimal width interval of the machine allows it to cover most of the plastic bag applications in the market including t-shirt bags, garbage bags, flat shopping bags, bags on rolls, etc.
