Introducing UV-LED systems into packaging and printing to overcome challenges in the heat shrink film label industry

Our partners are packaging and printing companies that specialize in high-speed printing of high-end heat shrink film labels such as PETG, PVC, and OPS.

Industry Pain Points

• Extremely Heat-Sensitive Material:

  Heat-shrink film is highly susceptible to premature shrinkage and wrinkling at 50℃-60℃. The significant infrared heat radiation from traditional mercury lamps can easily cause pattern distortion and misregistration.

• Limited Production Capacity and Yield:

  To avoid burning through the film, traditional processes necessitate reducing printing press speed, resulting in high scrap rates during startup and setup, severely limiting overall production line capacity.

Addressing the stringent requirements of "second-level drying and low-temperature maintenance" for heat-shrinkable film, Shenzhen Super-curing Opto-Electronic CO., Ltd. has tailored an intelligent low-temperature UV-LED curing system:

Intelligent Low-Temperature UV-LED Curing System Features

• Narrow-band cold light source:

  Locked to a precise wavelength of 365nm/395nm, eliminating infrared heat radiation. Combined with microchannel water cooling, the surface temperature of the film during curing is kept firmly below 35°C, preventing premature material shrinkage.

• High-uniformity optical system:

  Utilizing independently developed microlens optical technology, significantly improving the energy density and uniformity of the UV spot, achieving second-level deep and thorough curing on a high-speed rotary printing line of 200 meters per minute.

• Intelligent PLC linkage:

  The light source system and the printing host are fully automatically linked, supporting instant on/off operation and intelligent power tracking to prevent localized overexposure during shutdowns or deceleration.

Key Benefits

• Leap in Product Yield:

  Film deformation and edge warping caused by thermal stress are completely eliminated. The first-time setup pass rate has climbed to over 99.8%, and no cracking has occurred during subsequent high-magnification heat shrinking.

• Double Production Efficiency:

  Overall equipment efficiency (OEE) has increased by over 35%, completely unleashing the potential of high-speed printing presses.

• Sharply Reduced Overall Energy Consumption:

  Thanks to the high luminous efficacy and instant-on characteristics of UV-LEDs, overall power consumption in customer factories has been reduced by approximately 82% compared to traditional mercury lamps.

• Environmental and Safety Compliance:

  Zero VOC emissions and zero ozone generation during the curing process. Finished products are completely odorless and easily pass extremely stringent food-grade packaging safety certifications.

• Extended Light Source Lifespan:

  The industrial-grade UV-LED light source has a lifespan exceeding 20,000 hours, more than 20 times longer than traditional mercury lamps, requiring no maintenance for many years and significantly reducing subsequent maintenance and consumable costs.
