A bubble tea cup and PET thermoforming packaging manufacturer in Thailand has commissioned a high-specification ABA PET Three-Layer Sheet Co-Extrusion Line from TZ Machinery. The line pairs an 85 mm parallel twin-screw extruder with a 75 mm single-screw extruder, and was selected to raise output of high-clarity PET sheet for beverage cups and food packaging.
Projenin Arka Planı
Our relationship with this valued Thai client began at the Thailand Plastics & Rubber Exhibition last year. As a well-established manufacturer of bubble tea cups and PET thermoforming packaging, they initially approached us to repair the screw of their existing sheet extruder.
Impressed by our technical expertise, quality of service, and the proven efficiency of our multi-layer PET co-extrusion technology, the customer chose to partner with us again this year to expand their production capacity. They ordered a high-specification ABA PET üç katmanlı levha koekstrüzyon hattı featuring an 85 parallel twin-screw plus 75 single-screw configuration.

High-End Configuration & Key Features
To meet the client’s demanding standard for high-clarity, stable PET sheet production for beverage and packaging applications, the line was built with industry-leading components.
| System | Şartname |
|---|---|
| Line type | ABA three-layer co-extrusion |
| Screw configuration | 85 mm parallel twin-screw + 75 mm single-screw |
| Drive & control | Siemens main motors, Siemens servo motors, integrated Siemens PLC |
| Melt flow components | JC Times flow channels, melt metering pump, screen changer, feedblock, extrusion die |
| Sargı | Heavy-duty gantry-type dual-station winder |
| Target product | High-clarity PET sheet for bubble tea cups and thermoforming packaging |
Drive & Control System
The line is equipped with Siemens main motors, Siemens servo motors, and a fully integrated Siemens PLC control system. This combination ensures superior energy efficiency, precise torque management, and reliable automation across the whole line.
Extrusion Tooling & Melt Flow Systems
To guarantee immaculate melt homogeneity, continuous operation, and precise layer thickness control, we integrated premium components from JC Times, including the flow channels, melt metering pump, screen changer, feedblock, and extrusion die. The paralel çift vidalı PET levha ekstrüzyon makinesi section handles the core layer, while the vented single screw PET sheet extrusion line section delivers a stable outer layer.
Winding System
The line incorporates a heavy-duty gantry-type dual-station winder, allowing operators to handle large-diameter rolls effortlessly while maintaining uniform winding tension.

Results & Impact
By upgrading to our ABA PET sheet extrusion technology, the customer substantially reduced raw material costs by using recycled or core-layer materials in the B layer, while maintaining high visual and functional standards on the outer A layers.
The reliable Siemens automation and JC Times extrusion hardware ensure minimal downtime, high output, and consistent sheet quality required for high-speed thermoforming. Edge trim is returned to the line through a soundproof sheet edge scrap online crusher, which keeps the regrind stream clean and further supports the cost target.
This successful project reinforces our commitment to delivering tailored, high-end extrusion solutions to global packaging manufacturers.
SSS
ABA üç katmanlı PET levha koekstrüzyon hattı nedir?
Bu hat, iki adet dış A katmanı ve bir adet iç B katmanının aynı anda ekstrüde edildiği bir üretim hattıdır. A katmanlarında, yüzey kalitesi ve gıda ile temas açısından saf veya birinci sınıf PET kullanılırken, B katmanında geri dönüştürülmüş pul veya öğütülmüş malzeme kullanılır; bu da dış görünümü değiştirmeden hammadde maliyetini düşürür.
Neden 85 çift vidalı ekstrüderi 75 tek vidalı ekstrüderle birleştirmeli?
85 mm’lik paralel çift vidalı ekstrüder, yoğun dolgulu iç katman için güçlü karıştırma, gaz giderme ve üretim kapasitesi sağlarken, 75 mm’lik tek vidalı ekstrüder ise dış katman için istikrarlı ve homojen bir eriyik sunar. Bu iki ekstrüder birlikte üretim hacmi, eriyik kalitesi ve enerji tüketimi arasında denge sağlar.
Siemens kontrol sistemi bu hatta ne gibi bir katkı sağlıyor?
Siemens ana motorları, servo sürücüler ve entegre bir PLC, ekstrüderler, eriyik pompası, süzgeç değiştirici ve sarıcıda hassas tork ve hız yönetimi sağlar. Operatörler, tekrarlanabilir katman oranları, daha hızlı devreye alma ve daha az plansız duruş elde eder.
ABA yapısı hammadde maliyetinde ne kadar tasarruf sağlayabilir?
Tasarruf, katman oranına ve işlenmemiş ile geri dönüştürülmüş PET arasındaki fiyat farkına bağlıdır. B katmanı genellikle levha kalınlığının büyük bir kısmını oluşturduğundan, bu katmanın geri dönüştürülmüş pul veya tesis içi öğütülmüş malzeme ile değiştirilmesi, malzeme maliyetindeki azalmanın büyük bir kısmını sağlar.
PET levha üretim hattında neden eriyik dozaj pompası kullanılır?
The melt pump stabilises pressure and output at the die inlet, so sheet thickness and layer distribution stay constant even when extruder conditions drift. That stability is what makes thin, high-clarity PET sheet repeatable at production speed.
Can the line run recycled PET in the core layer?
Yes. The ABA structure is designed for it: recycled flakes or edge-trim regrind go into the B layer, while the A layers keep the surface clear and food-contact compliant. Vacuum degassing and melt filtration control volatiles and contamination.
