PET Film Designed for Reliable Industrial Printing
Kaixin PET-Z11 Series is a high-adhesion PET printing film developed for industrial printing applications that require stable ink bonding, excellent surface wettability, and consistent processing performance.
Compared with standard untreated PET film, this series is designed to improve ink adhesion and printing reliability through dual-sided PU primer pre-coating technology. It is suitable for applications such as appliance panels, industrial nameplates, control overlays, functional labels, display windows, and precision printed components.
With advanced coating and converting capabilities, Kaixin can also support material selection, protective film lamination, slitting, cutting, and other customized processing services based on customer production requirements.
Why Standard PET Film and Corona-Treated PET Film Are Not Enough
PET film is widely used in identifiers, panels, functional films, and industrial components because of its excellent physical and chemical properties. However, untreated PET film has low surface energy and chemical inertness, which can limit ink wetting and adhesion during printing.
Corona treatment is commonly used to temporarily improve the surface energy of PET film, but it also has several limitations. The treated surface may gradually lose adhesion performance over time, dyne levels may become unstable, and treatment coverage may not always remain consistent during storage or processing.
For demanding applications such as home appliance panels, industrial overlays, and fine graphic printing, stable long-term ink adhesion is more important than short-term dyne value improvement.
Kaixin PET-Z11 Series: Dual-Sided PU Primer Pre-Coated PET Film
Kaixin PET-Z11 Series uses dual-sided PU primer pre-coating technology to create a more stable bonding interface between the PET substrate and printing inks. Instead of relying only on temporary surface energy improvement, the coating forms a more permanent chemical modification layer on both sides of the film.
The polyurethane primer layer improves compatibility with common industrial printing inks, including PU, acrylic, and epoxy-based inks. It helps the ink spread more evenly across the surface and supports stronger adhesion after curing.
This structure also helps reduce curling caused by single-sided treatment and improves dimensional stability during printing, die-cutting, lamination, trimming, and final assembly.
Key Advantages of Kaixin PET Printing Film
Stable Ink Adhesion
Kaixin PET-Z11 Series is designed to provide reliable ink adhesion for industrial printing applications. Its adhesion performance comes from the PU primer pre-coated surface, rather than a temporary increase in dyne level.
Excellent Ink Wettability
The ink-friendly coating helps improve ink spreading and surface wetting. This can reduce common printing defects such as pinholes, ink retraction, uneven coverage, and edge burrs.
Better Dimensional Stability
The dual-sided primer pre-coated structure helps reduce curling and stress-induced deformation. This makes the film more suitable for high-precision die-cutting, trimming, lamination, and assembly processes.
Suitable for Fine Graphics and Multi-Color Printing
With stable surface wettability and adhesion, the film is suitable for fine characters, delicate lines, multi-color registration, and high-resolution printed patterns.
Reliable Performance After Storage
Under proper storage conditions, such as room temperature and a dry environment, the printing adhesion performance remains stable. This makes the film suitable for multi-batch production and advance material preparation.

Printing Performance Comparison
| Film Type | Ink Adhesion | Stability Over Time | Processing Reliability | Suitable Applications |
|---|---|---|---|---|
| Untreated PET Film | Limited adhesion because of low surface energy | Poor printing stability for demanding applications | Limited reliability in precision printing | Basic non-critical applications |
| Corona-Treated PET Film | Improved initial adhesion | Adhesion may decline as dyne level changes over time | Treatment coverage and surface energy may vary | General printing applications with shorter storage cycles |
| Kaixin PET-Z11 Printing Film | Stable ink adhesion through PU primer pre-coating | Reliable performance under proper storage conditions | Improved dimensional stability and reduced curling | Appliance panels, industrial overlays, fine graphics, and precision printing |
Applications in Appliance Panels and Industrial Components
Kaixin PET printing film is suitable for mid-to-high-end appliance panels and industrial printed components where both appearance and long-term durability are required.
In appliance panel applications, the film can be used as a surface decorative material to support metallic brushing effects, gradient colors, printed icons, transparent display windows, and functional interface designs. It can also serve as a functional carrier for printed patterns, touch buttons, transparent areas, and display-related structures.
Typical application areas include:

Value-Added Converting Services
In addition to supplying PET printing film, Kaixin provides value-added converting services to help customers reduce internal processing steps and improve production efficiency.
Available services include protective film selection, lamination, precision slitting, narrow roll cutting, sheet cutting, and customized processing based on different product specifications and production line requirements.
Customers can choose finished or semi-finished delivery formats according to their own printing, die-cutting, lamination, hot pressing, and final assembly processes.

Frequently Asked Questions
Are there any limitations on ink compatibility?
Kaixin PET-Z11 Series offers good compatibility with mainstream industrial printing inks, including PU, acrylic, and epoxy-based inks. Before mass production, we recommend sample testing based on the customer’s specific ink formulation, curing process, and adhesion requirements.
Is additional corona treatment required before printing?
Normally, no additional corona treatment or preheating treatment is required. The film’s strong ink adhesion comes from the permanent chemical modification coating on the film surface, rather than a temporary increase in surface energy.
Will ink adhesion decrease after prolonged storage?
Under proper storage conditions, such as room temperature and a dry environment, the printing adhesion performance shows no significant deterioration. This makes the film suitable for phased production, advance material preparation, and multi-batch manufacturing.
Is this PET film suitable for fine graphics and high-resolution printing?
Yes. The primer-coated surface helps improve ink wetting and spreading, reducing common printing issues such as pinholes, ink retraction, uneven coverage, and edge burrs. It is suitable for fine characters, delicate lines, and multi-color registration.
Does the dual-sided primer coating affect die-cutting or lamination?
No. The dual-sided primer pre-coated structure helps reduce curling and improve dimensional stability. It supports better processing reliability during die-cutting, trimming, lamination, and final assembly.
Does Kaixin support slitting, cutting, and protective film lamination?
Yes. Kaixin provides small-roll slitting, custom-sized cutting, protective film lamination, and other converting services. Customers can choose finished or semi-finished delivery formats according to their production line requirements.
Which materials can Kaixin PET-Z11 replace?
Kaixin PET-Z11 is suitable for replacing untreated PET film or corona-treated PET film in applications where long-term ink adhesion stability, consistent printing performance, and advance material preparation are required.
