Types of PET Sheet Extrusion Line

Four configurations for different applications

Virgin PET Sheet Production Line

Virgin PET Sheet Production Line

Designed for producing high-transparency PET sheets with excellent appearance and mechanical properties. Widely used in food packaging, medical packaging, and high-end thermoforming products.


Recycled PET Sheet Extrusion Line

Recycled PET Sheet Extrusion Line

Processes recycled PET flakes into quality sheets with integrated melting, filtration, and degassing.


PET Thermoforming Sheet Production Line

PET Thermoforming Sheet Production Line

Optimized for applications requiring excellent forming performance, including disposable containers, trays, cups, and packaging products.

PETG Sheet Production Line

PETG Sheet Production Line

The same twin screw extrusion line processes PETG (PET modified with glycol) — an amorphous co-polyester with superior impact resistance, exceptional clarity, and easier thermoforming vs. standard PET. PETG sheets serve medical device packaging, cosmetic packaging, point-of-sale displays, and high-end consumer goods, and home decoration (cabinet panels, wardrobe doors, wall panels, kitchen backsplashes). JWELL's multi-zone temperature control ensures stable processing within PETG's narrow thermal window (230-260 C).

What's the Difference: PET vs APET vs CPET vs RPET?

Not all PET materials are the same. Understanding the differences between PETG, APET, CPET, and RPET is essential when choosing the right sheet extrusion solution for your application. Below is a comparison across key technical parameters: IV (Intrinsic Viscosity), melt temperature, mechanical strength, and processing characteristics.

IV (Intrinsic Viscosity)

IV (Intrinsic Viscosity)

— Measures polymer molecular weight. Higher IV = higher molecular weight = better mechanical properties but harder to process.

Tg (Glass Transition Temperature)

Tg (Glass Transition Temperature)

Temperature at which the material transitions from rigid to rubbery state.

Tm (Melting Point)

Tm (Melting Point)

Temperature at which crystalline regions melt. Amorphous materials (APET, PETG) have no distinct Tm.

Summary for Sheet Extrusion Buyers

• Choose PETG if you need maximum clarity + impact resistance + easy thermoforming (medical, cosmetic, display, home decoration)

• Choose APET if you need food-grade clarity at lower cost for standard packaging (trays, blisters, clamshells)

• Choose CPET if your sheets must withstand microwave/oven temperatures (meal trays, airline catering)

• Choose RPET if sustainability and cost are priorities, with acceptable clarity/toughness trade-offs

JWELL Advantage: All four material types can be produced on JWELL twin screw extrusion lines with appropriate configuration. The same base platform handles PETG and APET with simple parameter changes. CPET requires an optional crystallization station, and RPET benefits from enhanced filtration and degassing modules. Contact salcs@jwell.cn to discuss your specific material and application requirements.

PET Material Classification — Detailed Characteristics Overview

APET (Amorphous PET)

APET (Amorphous PET)

Features — Transparent, good gloss, easy to process. Relatively weak heat resistance and impact resistance compared to CPET.


Applications — Mainly used for food packaging — beverage bottles, food boxes, blister products (blister shells, trays, clamshell containers). Ideal for applications requiring crystal-clear visibility of the packaged product.


RPET (Recycled PET)

RPET (Recycled PET)


Features — Made from recycled PET bottle flakes/flakes. Environmentally friendly, reduces demand for virgin PET. Lower carbon footprint, supports circular economy goals. Mechanical properties slightly lower than virgin PET but sufficient for most packaging applications.


Applications — New bottles (bottle-to-bottle recycling), containers, packaging materials, textile fibers, strapping, sheet extrusion for thermoformed packaging.


PETG (PET Glycol-modified)

PETG (PET Glycol-modified)

Features — Glycol modification gives PETG superior toughness and impact resistance. Better heat resistance than APET, excellent thermoforming properties, crystal-clear transparency. No crystallization issues — easier to process, no drying required. Can be bonded, die-cut, and printed easily.


Applications — Medical device packaging (sterile trays), electronic product packaging, POS display racks, cosmetic packaging, home decoration panels (cabinet doors, wall panels), labels and signage, high-end folding cartons.


CPET (Crystalline PET)

CPET (Crystalline PET)

Features —  Achieved through nucleation and controlled crystallization. High heat resistance — withstands microwave and conventional oven temperatures (up to 220 C). Opaque appearance (typically white or black). Excellent dimensional stability at elevated temperatures. Higher mechanical strength than amorphous variants.


Applications —  Dual-ovenable meal trays (microwave + oven), airline meal containers, frozen food packaging, ready-meal trays. The go-to material when heat resistance is non-negotiable.

Twin screw eliminates pre-drying equipment, provides better mixing and degassing, reduces viscosity loss, and achieves higher output.

?
Can this line process RPET and PETG?

Yes. Multi-component metering feeder handles blends of virgin PET, RPET flakes, and PETG. Vacuum venting removes contaminants from recycled materials.

?
What thickness can be produced?

PET: 0.15-1.5 mm. PETG: 0.2-2.0 mm. Width is customizable.

?
What are the production capacities?

Single layer ~600 kg/h | Multi-layer 600-800 kg/h | High efficiency 1000-1200 kg/h

?
