With over 23 years of experience in mold making and plastic injection, Goldwin goes beyond manufacturing excellence to offer advanced secondary processes, including UV printing—a powerful way to add branding, decoration, and value to your plastic products.

Plastics Are Everywhere—And Many Are Decorated

Take a quick look around. Whether you’re at your desk, in your car, or sipping coffee, you’re surrounded by plastic items—many of which feature colorful graphics or branding. This decoration is often achieved using UV printing, which allows manufacturers to apply vibrant, high-resolution imagery directly onto plastic surfaces.

From consumer goods and drinkware to automotive parts and promotional items, UV printing on plastic enhances both aesthetics and functionality, creating long-lasting, visually impactful designs.

What is UV Printing on Plastic?

UV printing is a cutting-edge digital printing technology that uses ultraviolet light to instantly cure specially formulated inks as they are printed. This allows for full-color graphics with exceptional durability—even on curved, cylindrical, or irregular plastic surfaces.

UV printing is compatible with a variety of plastics, including:

• Polypropylene (PP)
• Polyethylene (PE)
• Polycarbonate
• Acrylic
• Tritan
• ABS, and more

Whether it’s flat or cylindrical, UV printing delivers crisp, permanent images with excellent adhesion—a crucial factor in achieving lasting print performance.

Achieving Optimal Adhesion with Pre-Treatment

Plastic surfaces often require pre-treatment to ensure ink properly adheres. At Goldwin, we tailor the process based on your product’s material and intended use.

• Primer Wipes: Used as a base for UV adhesion on many plastics.
• Flame, Corona, or Plasma Treatment: Advanced surface treatments that increase bonding strength.
• Material-Specific Primers: Such as PP Primer for polypropylene and PL Primer for various engineered plastics.

Products like drinkware demand a high level of adhesion to endure frequent dishwashing, while promotional items may only require basic pre-treatment for short-term use.

UV Printing on Tritan and Specialty Plastics

Tritan plastic, known for being BPA-free and food-safe, is growing in popularity for drinkware and child-safe products. However, Tritan is notoriously difficult for ink to adhere to.

With specialized UV inks such as T2, Goldwin can print on Tritan without pre-treatment while still achieving vibrant, abrasion-resistant finishes in full CMYK and white.

Machine Technology: Flatbed, Cylindrical, and High-Speed Printing

Goldwin utilizes advanced UV printing equipment capable of decorating various shapes and volumes:

• Flatbed UV Printers: Ideal for flat or semi-flat surfaces like panels and nameplates.
• Cylindrical Printers: Perfect for bottles, cups, and tubes.
• Automated High-Speed Printers: Great for mass production of promotional cups, such as stadium cups—common in events, sports venues, and theme parks.

With features like automatic load/unload and in-line pre-treatment, our systems enable fast, high-volume UV printing with consistent quality.

Goldwin offers UV ink solutions designed for optimal performance across various plastics:

• T2 UV Ink – For Tritan plastic, no pre-treatment required
• S1 UV Inkjet – For hard plastics and durable graphics
• XFlexx & BB Ultra – For flexible plastic items

Each ink provides unique benefits in color vibrancy, flexibility, and abrasion resistance, depending on the product’s application.
