The PET Single Screw Twin Screw Sheet Extrusion Line developed by Jwell is designed for high-efficiency production of PET and PLA sheets used in thermoforming and packaging applications. The system integrates advanced extrusion technology with optimized process control to ensure stable output, high transparency, and consistent sheet quality.

This production line eliminates the need for traditional drying and crystallizing units, significantly simplifying the production process while reducing overall energy consumption. It is widely used in environmentally friendly packaging industries where material stability and production efficiency are critical.

As part of jwell machinery, the system reflects a focus on energy efficiency, process simplification, and industrial-scale reliability.

Advanced extrusion system design for stable performance

The extrusion line adopts a carefully engineered screw structure designed to reduce viscosity loss during processing. This ensures that PET and PLA materials maintain stable molecular characteristics throughout the melting and forming stages.

The segmented screw configuration enhances melting uniformity and improves material flow stability. This results in better sheet transparency, improved mechanical strength, and reduced production defects.

Within jwell extrusion machinery, screw systems are optimized to balance output efficiency and material protection, ensuring consistent performance during long production cycles.

Degassing system and simplified production process

A key feature of this PET sheet extrusion line is the integrated degassing system, which effectively removes moisture and volatile components during processing. This improves sheet clarity and reduces internal defects.

By eliminating the need for separate drying and crystallization units, the production process becomes more compact and efficient. This reduces equipment footprint, lowers energy consumption, and simplifies operational management.

The simplified workflow makes the system particularly suitable for manufacturers seeking efficient and stable PET sheet production with reduced operational complexity.

Multi-layer structure capability and material flexibility

The PET Single Screw Twin Screw Sheet Extrusion Line supports single-layer, multi-layer, and high-capacity configurations. Multi-layer systems can produce 2–5 layer structures, where each layer can be composed of different materials, recycled content, or color masterbatch.

This flexibility allows manufacturers to optimize product performance while controlling material costs. It is especially useful in packaging applications requiring barrier properties, surface quality, or structural reinforcement.

In jwell plastic machinery, multi-layer co-extrusion systems are designed to ensure precise layer bonding and uniform distribution across the sheet structure.

High-efficiency cooling and calendering system

The line is equipped with a high-precision calendering system featuring thin-wall roller design. This structure improves cooling efficiency and enhances sheet surface quality during production.

The improved heat exchange performance ensures stable sheet thickness and reduces internal stress, resulting in better thermoforming performance downstream.

Cooling stability is essential for PET and PLA materials, and this system ensures consistent dimensional control even at high production speeds.

Precise dosing and raw material control system

A multi-component dosing feeder is integrated into the production line, allowing precise control of virgin materials, recycled materials, and masterbatch ratios. This ensures consistent material formulation across production batches.

The system improves production flexibility while supporting sustainable manufacturing strategies by enabling controlled use of recycled PET materials.

This level of precision contributes directly to product consistency and reduces material waste throughout the production process.

Product structure and technical configuration

The PET sheet extrusion line is available in multiple configurations depending on production requirements and output capacity.

These configurations allow manufacturers to select equipment based on output requirements, material structure, and application complexity.

Energy efficiency and operational advantages

The PET sheet extrusion line is designed with energy-saving principles, incorporating optimized drive systems and thermal management technology. Compared with conventional systems, energy consumption is significantly reduced while maintaining high output levels.

The elimination of drying and crystallization steps further contributes to energy efficiency and operational simplicity. This reduces production costs and improves overall manufacturing sustainability.

In jwell extrusion machinery, energy optimization is a key engineering priority, ensuring long-term cost efficiency for industrial users.

Application scope of PET and PLA sheets

Sheets produced by this system are widely used in thermoforming packaging applications. These include food packaging trays, transparent containers, and biodegradable packaging solutions.

The material flexibility of PET and PLA allows manufacturers to meet increasing environmental requirements while maintaining product performance standards.

The extrusion line ensures that sheets maintain excellent transparency, uniform thickness, and stable forming characteristics, making them suitable for high-end packaging applications.

Production stability and quality assurance

The system is designed for continuous industrial operation with stable output performance. Precision control systems ensure consistent sheet thickness and surface quality throughout production cycles.

Online thickness measurement systems and die control technology help maintain strict tolerance levels, improving product consistency and reducing material waste.

As part of jwell machinery, quality assurance is integrated into every stage of production line design, ensuring long-term reliability and performance stability.
