The Jwell PE breathable film production line represents a breakthrough in the extrusion casting industry, delivering high-efficiency solutions for producing air-permeable polyethylene films. Designed with precision engineering, this line utilizes PE air-permeable plastic granules as raw materials. Through a controlled extrusion casting process, these granules—modified with inorganic fillers—are melted and stretched to form a micro-porous film structure. The resulting film combines strength, flexibility, and breathability, making it ideal for applications in hygiene, medical protection, packaging, and industrial filtration. As high quality plastic film extrusion machine exporter, this blog post will share the performance of Jwell pe breathable film production line, its applications, etc.
Science Behind PE Breathable Film Extrusion
At the core of the PE breathable film production process lies the principle of controlled stretching. During production, molten PE-modified air-permeable plastic granules are extruded through a flat die and rapidly cooled on a chill roller. Subsequent high-speed stretching causes the inorganic filler particles to separate the polymer matrix, forming nano- to sub-micron pores that allow vapor transmission but block liquid penetration.
This unique micro-porous structure is the reason breathable films can provide both water resistance and air permeability. Jwell’s advanced process technology ensures uniform pore distribution and film thickness, leading to superior mechanical properties and consistent product quality.
Extrusion Casting Technology in Jwell Breathable Film Line
The Jwell PE breathable film extrusion line employs a high-precision extrusion casting system, featuring a single or twin-screw extruder, T-die, casting roller, and stretching section.
Key features include:
-
Stable extrusion control: The system maintains precise temperature and pressure stability, ensuring consistent polymer melting and film formation.
-
Advanced die design: The flat die is engineered for uniform flow distribution and smooth surface quality.
-
High-speed stretching system: Mechanical stretching at controlled ratios promotes optimal pore formation and film uniformity.
-
Automatic thickness control: Integrated measurement sensors continuously adjust film thickness across the width, guaranteeing product stability.
Together, these technologies make Jwell’s line a benchmark in PE breathable film extrusion for both hygiene and industrial sectors.
Material Characteristics and Processing Parameters
In the Jwell PE breathable film production line, polyethylene (PE) acts as the matrix material, modified with inorganic fillers such as calcium carbonate (CaCO₃). The filler content typically ranges from 30% to 50%, directly influencing film porosity and mechanical properties.
Critical processing parameters include:
-
Extrusion temperature: 200–250°C, ensuring proper melting and dispersion of fillers.
-
Stretching ratio: 2–4 times, determining pore size and air permeability.
-
Cooling rate: Rapid cooling enhances crystallization, stabilizing the film structure.
These parameters must be finely tuned to balance film strength, elasticity, and permeability. Jwell’s intelligent control system automates parameter adjustment, ensuring repeatable, high-quality output.
