Developing new polymer films for packaging, agriculture, or medical applications requires precise control over the blowing process. The quality of your final film—its clarity, strength, and barrier properties—is directly tied to the performance of your film blowing extruder. For R&D, having a reliable and controllable lab-scale film blowing line is essential for understanding how formulation and

In the world of plastic film production, two dominant manufacturing processes stand out: blown film extrusion and cast film extrusion. These methods are essential for creating flexible plastic films used in countless industries. But what exactly are the differences, and how do these technologies contribute to a more efficient and sustainable world? Let’s dive into

I. Comparison of blown film characteristics of three biodegradable materials Material Melt strength Thermal stability Difficulty PLA Low Poor (easily hydrolyzed and thermally degraded) The membrane bubble is prone to shaking, has large lateral shrinkage, and the membrane is brittle. PBAT medium better Highly adhesive, prone to sticking, and difficult to roll up. PBS Low/medium

When developing polymer films, blown film machine lines are used. Laboratory blown film machines are divided into single-layer and multi-layer types. The R&D team needs to select the technology according to its own needs. Single-layer vs. multi-layer co-extrusion blown film experimental lines: How to choose according to R&D needs?
