— A Precision Solution for Better Lamination

In the manufacturing of RFID-integrated certificate labels, a common structure involves encapsulating the RFID chip between PET film layers, then laminating paper layers on both sides. However, due to the non-porous and smooth nature of PET, traditional lamination methods often suffer from poor adhesion, leading to delamination, warping, or edge lifting over time.

To address this challenge, we introduce a highly effective process:
laser elliptical hole perforation on the PET layer. This method enables adhesive glue to penetrate directly through the PET film, creating a stronger bond between the PET and paper layers, thus enhancing the overall durability and appearance of the final product.

Key Advantages of Laser Elliptical Hole Perforation:

✅ Precision-Engineered Micro Holes

Our advanced laser systems create uniform elliptical holes with customizable size, spacing, and pattern. The perforation ensures effective glue penetration without affecting the visual appearance or electronic function of the RFID label.

✅ Safe for RFID Chips and Antennas

Laser elliptical hole perforation is applied only in non-sensitive areas, avoiding the RFID chip and antenna zones. This ensures no interference with signal transmission or component safety.

✅ Clean, Burr-Free Finish

Unlike mechanical punching, laser elliptical hole perforation produces clean, burr-free holes with minimal thermal impact. The process maintains the integrity and cleanliness of both PET and paper surfaces.

✅ Reduced Defect Rate

By improving adhesive contact between layers, this process minimizes common defects such as bubbling, delamination, and poor edge sealing. The result is higher product quality and increased yield.

Broad Applications, Proven Results

Laser elliptical hole perforation is ideal for a wide range of products including:

• RFID-enabled certificates

• Smart tickets

• Tamper-evident documents

• High-security printed labels

This technology has been successfully implemented by leading RFID label manufacturers and has delivered consistent bonding performance and high end-user satisfaction.
