BOPET Film Extrusion Production Line

USEON BOPET Film Extrusion Line

High-Efficiency and Versatile BOPET Film Production Line

The USEON BOPET Film Extrusion Line is an advanced extrusion system designed for the production of BOPET (Biaxially Oriented PET) films. It is especially suitable for manufacturing high-quality PET-based packaging films and, thanks to USEON’s twin-screw extruder technology, delivers better dispersion, higher output, and lower energy consumption compared to conventional single-screw extruders.

What Is BOPET Film Extrusion?

A BOPET film extrusion line is a continuous production system in which PET resin is homogeneously mixed with functional additives (such as anti-slip, anti-static, and anti-oxidant additives) and converted into film form. The film structure is typically designed in a multi-layer A/B/C configuration, and high-performance film products are obtained through a co-extrusion process.

Basic Formulation

In BOPET film production, PET resin is compounded with the following additives:

• Anti-slip
• Anti-static
• Anti-oxidant additives

These additives enhance both film performance and process stability.

BOPET Film Application Areas

BOPET films offer a wide range of applications, including:

• High-quality packaging films
• Food and consumer goods packaging
• Electronic and technical films
• Industrial film solutions

The multi-layer film structure provides excellent mechanical strength, superior surface quality, and high transparency.

Technological Features and Advantages

The USEON BOPET Film Extrusion Line offers the following advanced process advantages:

• No pre-drying required: Eliminates conventional drying, simplifying the process and saving energy
• High-efficiency vacuum system: Minimizes PET intrinsic viscosity (IV) drop
• Optimized screw design: Prevents yellowing and thermal degradation
• Intelligent closed-loop control system: Improves process stability and product quality
• Reduced polymer degradation: Short residence time preserves film quality
• Enhanced dispersion performance: Ensures more uniform additive distribution and may reduce additive dosage
