Laser-Ablative Dry Film
Delivery Form: Rolls or sheets
Operating Environment: day‑light working environment, no darkroom required
Dry process: no developer required
Shanghai Mac Corporation is a leading Laser-Ablative Dry Film manufacturer and supplier.
Laser-Ablative Dry Film (LADF) is a high-performance dry film designed for direct imaging on infrared laser systems, including digital flexo and letterpress imagesetters. The film consists of a polyester base coated with an ablative black layer and a protective cover sheet that is removed prior to use. This product is primarily used in computer to plate (CTP) workflows for flexographic, letterpress, and offset plate making, as well as for image quality control. In practical production, LADF eliminates the need for wet chemical processing and darkroom handling, directly addressing the industry's demand for faster turnaround, reduced process steps, and lower environmental impact. The film delivers high contrast, high optical density, and excellent dimensional stability, ensuring precise pattern transfer even at fine line widths and small dot sizes. Its ablative coating responds cleanly to infrared laser exposure, producing sharp, residue-free images that are ready for UV exposure of printing plates. The film offers good handling properties and resists curling or stretching during lamination and transport.

Packaging of Laser-Ablative Dry Film
Standard Packaging
Each roll of Laser‑Ablative Dry Film is wound on a sturdy plastic core and wrapped with moisture‑proof PE film. The roll is then placed in a reinforced export carton with edge protectors and desiccant packs to control humidity. Cartons are stacked on fumigated wooden pallets and secured with strapping bands for international shipping.
Shipping
We support FCL and LCL sea freight, air freight, and express delivery depending on order quantity and destination. Common trade terms include EXW, FOB, and CIF; other terms may be available upon request. Shipping costs are calculated based on cargo volume, gross weight, destination, and selected transportation method.
Lead Time
Sample: 3–7 working days
Standard orders: 20–30 working days
Customized orders: 25–40 working days
Q: What laser systems are compatible with this dry film?
A: The film is designed for infrared laser systems, including 1064 nm (YAG) and 830 nm (diode) CTP devices. It works with most commercial flexo and letterpress imagesetters, as well as offset CTP equipment that uses IR ablation. We recommend testing the specific energy setting on your machine before production.
Q: What is the difference between 7 mil and 5 mil thickness?
A: The 7 mil (175 μm) version offers greater dimensional stability and is preferred for applications requiring tight registration or when handling large-format plates. The 5 mil (125 μm) film is thinner and more flexible, making it suitable for standard flexo plates and applications where lower material consumption is desired. Both versions provide the same ablation performance and optical density.
Q: How should I store the film before use?
A: Store the film in its original packaging, laid flat, at a temperature below 28 °C and humidity below 70% RH. Avoid direct sunlight, high temperature, and humid environments. The shelf life is 18 months under recommended storage conditions. After removing the protective cover sheet, handle the film with care—use rubber gloves to prevent fingerprints and surface scratches.
Q: What information do you need for a custom quotation?
A: Please provide the required film thickness (7 mil or 5 mil), roll width and length, target laser wavelength, order quantity, and destination country. If you have specific packaging or shipping requirements, please also include those details. We will reply with a formal quotation within 24 hours.
Q: Is this film suitable for corrugated board flexo printing?
A: Yes. The film is particularly suitable for corrugated board flexo plate making and other paper-based substrate applications. Its high contrast and resolution (1–99% @ 175 lpi) ensure sharp dot reproduction, which is critical for corrugated post‑print and high‑quality flexo jobs.
Q: What quality standards does the product meet?
A: The film is manufactured under ISO 9001 quality management systems. Each batch is tested for optical density, ablation sensitivity, and dimensional stability. Certificates of analysis (COA) are available upon request.
