In Mexico, JWELL supplied a PET sheet extrusion line. The line is rated for a stated capacity of 1,000 kg/h and is configured for a finished product width of 1,200 mm, producing PET sheets (amorphous PET thermoforming sheet). The project highlights a high single-line output of 1,000 kg/h. The complete scope covers the extrusion section, the three-roll polishing and cooling calender and the corresponding downstream handling equipment. Final installation, commissioning and acceptance data will be published after confirmation with the customer.

This project required a production solution for PET sheet in Mexico. The customer operates in Latin America and commissioned the line in 2026 to supply PET sheets (amorphous PET thermoforming sheet) for food and beverage packaging trays and related applications.
Compared with standard-width flat extrusion, a line at 1,200 mm finished width with a stated output of 1,000 kg/h places higher demands on melt distribution, thickness control, cooling, web handling and the coordination of the complete production line.

JWELL supplied a PET sheet extrusion line solution based on its JWELL PET sheet extrusion platform. The line combines the extrusion system with a flat die, three-roll polishing and cooling calender, cooling and haul-off equipment and the downstream finishing section. The individual sections operate as one coordinated system to support consistent product formation and stable production.
The line was proposed at a stated output of 1,000 kg/h for a finished width of 1,200 mm. The final screw configuration, die size and downstream layout are defined during project review according to the raw material formulation, product specification and factory conditions.

Note: The table above is a reference configuration for the corresponding JWELL extrusion platform. Final equipment list and model numbers depend on raw material formulation, product specification, target capacity and site conditions.
rPET/virgin PET feeding → Pre-crystallization， Dehumidifying & Drying → Tiwn-scrw extrusion → T-die distribution → J-type Three-roll calender → Silicone oil coating →Oven→ Haul-off → Accumulator →3 station automatic winder
PET must be crystallized before drying: amorphous pellets soften and stick together when heated, which would block the drying hopper and the extruder throat. The pre-crystallizer first converts the pellets into a stable crystalline form, then the dehumidifying dryer reduces the moisture content to a very low level, because residual moisture hydrolyzes the PET chain and causes IV loss, haze and brittleness in the finished sheet.
After plasticizing in a parallel twin-screw extruder, the melt is filtered to remove gels and contaminants (particularly important when rPET flakes are used) and delivered at constant pressure by a melt pump for uniform gauge. The melt passes through a flat die onto a three-roll polishing stack that determines the sheet's optical clarity and surface quality. Inline thickness gauging with closed-loop die adjustment, edge trimming and a stable haul-off and winding/cutting section complete the line, keeping the finished PET sheet within tight thickness and clarity tolerances for thermoforming applications.
Note: The final line configuration can be adjusted according to the raw material formulation, product thickness, surface structure, roll width, production capacity and the level of automation required.
The installation and commissioning scope for this project covers the main extrusion system, die and forming section, cooling and haul-off equipment and the downstream finishing or winding unit.
During trial production the technical team checks the coordination of the complete line, including extrusion stability, melt distribution across the working width, cooling, haul-off synchronization and finished-roll or cut-sheet quality.
Installation duration: 7 days
Commissioning duration: 5 days
Technical support: [On-site / Remote / Both]
Acceptance method: [FAT / SAT / Customer production test]
Operator training: [Operation / Maintenance / Process adjustment]
Following installation and parameter adjustment, the production line undergoes trial production and project verification. The verification process focuses on production capacity, product width, thickness control, continuous operating stability and finished-product quality.
| Verification Item | Project Target | Verified Result |
| Production Capacity | 1,000 kg/h | 1,000 kg/h |
| Finished Product Width | 1,200 mm | 1,200 mm |
| Product Thickness | According to customer specification | 0.2-2mm |
| Continuous Test Run | Stable continuous production | 72 hours |
| Final Acceptance | Customer project requirements | [Passed FAT/SAT] |
Depending on the raw material formulation and the finished product specification, the output of this line can be used for:
- food and beverage packaging trays
- blister and clamshell packaging
- thermoformed containers
- display and visual packaging

Q: What is the capacity of the Mexico PET sheet project?
A: The stated production capacity of this project is 1,000 kg/h.
Q: What is the finished product width of the Mexico PET sheet line?
A: The line is configured for a finished product width of 1,200 mm.
Q: Why is moisture control important for PET sheet extrusion?
A: PET is moisture sensitive. Intrinsic viscosity and sheet quality are protected through proper raw-material drying and moisture control before and during extrusion. The final drying configuration is defined at project review.
Q: What information is needed to configure a similar extrusion line?
A: Buyers should provide the required product width, thickness range, raw material formulation, layer structure, surface type, target capacity, roll dimensions, electrical standard and workshop limitations. JWELL can then evaluate the extruder and downstream equipment configuration.
Q: What is the delivery and installation time for a similar project?
A: [To be confirmed - delivery time depends on line configuration, customization scope and the production schedule at the time of order.]
