Stable & Consistent Production
CAI PET cup printing machines use a precision ink control system and proportional ink ducts to maintain consistent ink supply and color performance during high-volume production. For challenging surface materials such as PET and rPET, corona discharge power and ink curing power can be precisely adjusted to improve ink adhesion and curing performance. Meanwhile, the water-cooling system keeps the printing rollers running smoothly and stably. Together, these technologies help ensure consistent print quality throughout long, high-speed production runs.


White Base Printing Technology
PET’s transparency and light refraction can affect the appearance and color accuracy of printed graphics, while rPET’s more complex material composition may cause issues such as yellowish tones and inconsistent surface curing. To address these challenges, CAI has developed white underprinting technology, which applies a layer of white ink within the same printing process before the color layers. This helps minimize the visual impact of the cup material, allowing printed graphics to appear more vibrant, accurate, and closer to the original artwork, while meeting the strict color requirements of major brands.

Global PET Brand Printing Cases

In accordance with the requirements of high-capacity production of coffee cups made of PET, our 8-color printing machine S608 by CAI boasts both speed and stability when printing the Luckin Coffee cups. This machine can produce up to 600 cups in a minute, thus being designed for mass production, during which high color accuracy and print quality are guaranteed in long-run production processes.n.

CAI offers a high-capacity printing service for KFC K-Coffee PET cups, ensuring the stability of the production process and print quality in delivering large volumes of orders. The printing machine is made to deliver high-speed production, while maintaining stable color registration and print quality throughout. In applications related to food packaging, the necessary components of the machine are lubricated using Klüber lubricant which supports high demands of food safety and hygiene.
Customer from Worldwide
CAI uses Klüber food-grade lubricants on key gears and printing components to help minimize contamination risks. In addition, CAI Group has its own brand specializing in the production and supply of food-grade printing inks. With products tested by authoritative third-party institutions, CAI provides PET cup printing solutions designed to meet food packaging safety requirements.
The main consumables are printing plates, inks, and a small number of wear parts. Beyond these, the machine mainly requires electricity and limited labor, with minimal material waste during production. Printed cups can also be recycled within the same material stream, helping reduce waste and carbon emissions. This makes CAI direct printing a cost-effective and environmentally friendly solution for PET cup production.
No. CAI’s white base printing technology is integrated into the same printing machine. After the white base layer is printed and cured, the color graphics can be printed directly without additional processing steps. For white base printing applications, the current maximum printing speed is around 300 cups/min, depending on the cup and printing requirements.
CAI’s self-developed vision inspection system is specially optimized for PET cup printing. Based on years of experience with curved-surface printing, it provides more accurate and reliable defect detection, helping customers reduce defective products, improve quality control, and minimize customer complaints.
