Printing on polycarbonate films can be done using different methods such as screen printing and flexo printing. For screen printing, you can place down the polycarbonate sheet or film you want to print and put a square piece of cardboard below it. Set the screen over the polycarbonate material and pour small quantity of the chosen ink throughout the screen top horizontally. For flexo printing, you apply ink on an anilox roller, which works with the doctor blade. This controls the process of producing an even layer of ink.
Polycarbonate films can be cut, die-cut, embossed, or thermoformed using various methods and equipment. Some of the common ways are:
- Cutting: Polycarbonate films can be cut using a sharp knife, scissors, or a guillotine. However, for more precise and accurate cutting, CNC routers are preferred. CNC routers use computer-controlled cutting tools to trim the excess material from the formed part. CNC routers can cut parts of any size and shape with high precision and repeatability.
- Die-cutting: Polycarbonate films can be die-cut using a custom die that is created for a specific shape or pattern. Die-cutting involves using specially positioned blades mounted on a strong backing and constructed into a pre-determined form, to cut patterns and shapes into the material. The mounted steel blades are pressed onto the material in order to cut the required shapes. Die-cutting is generally used for thinner gauge materials with less complicated trim specifications.
- Embossing: Polycarbonate films can be embossed using a heated metal die that has a raised design on its surface. Embossing involves pressing the heated die onto the film to create a raised or indented impression of the design. Embossing can add texture, depth, and visual appeal to the film.
- Thermoforming: Polycarbonate films can be thermoformed using heat and pressure to mold them into a desired shape. Thermoforming involves heating a sheet of polycarbonate film to its forming temperature and then pulling it over or pushing it into a mold with either vacuum or pressure. The formed part is then cooled, removed from the mold, and trimmed. Thermoforming can create complex shapes and contours with polycarbonate films.
Polycarbonate films can be bonded or laminated using various methods and materials. Some of the common ways are:
- Adhesive bonding: Polycarbonate films can be bonded using different types of adhesives, such as solvent-based, water-based, hot melt, pressure-sensitive, or UV-curable. Adhesive bonding involves applying a thin layer of adhesive to one or both surfaces of the films and then pressing them together. Adhesive bonding can provide a strong and durable bond that can resist heat, moisture, and chemicals.
- Heat sealing: Polycarbonate films can be bonded using heat and pressure to melt and fuse the films together. Heat sealing involves placing the films between two heated plates or rollers and applying pressure to create a seal. Heat sealing can provide a fast and easy bond that can withstand high temperatures and pressures.
- Ultrasonic welding: Polycarbonate films can be bonded using high-frequency sound waves to create friction and heat that melt and join the films together. Ultrasonic welding involves placing the films between two metal horns that vibrate at ultrasonic frequencies and apply pressure to create a weld. Ultrasonic welding can provide a clean and precise bond that can resist water, air, and dust.
- Lamination: Polycarbonate films can be laminated using different types of materials, such as glass, metal, paper, or other plastics. Lamination involves bonding a layer of material to one or both sides of the film to enhance its properties or appearance. Lamination can provide a protective and decorative coating that can improve the strength, stiffness, transparency, or functionality of the film. Lamination can be done using different techniques, such as roll lamination, flame lamination, or adhesive-free lamination.
Polycarbonate films can be cleaned and maintained using simple and gentle methods and materials. Some of the common ways are:
- Remove dust and dirt: Use a soft brush, a microfiber cloth, or a hair dryer to gently blow off any dust and dirt from the surface of the film. Avoid rubbing or wiping the film with a dry cloth, as this may scratch the film. You can also use compressed air to remove dust from hard-to-reach areas.
- Wash with lukewarm water and mild soap: Mix together your water and soap in a bucket and wash the film using a soft sponge or microfiber cloth to avoid scratching the material. Make sure your soap has no harsh chemicals that could damage the film, such as alcohol, ammonia, or aromatics. Rinse the film thoroughly with clean water and let it air dry or use a soft cloth to pat it dry.
- Use a special cleaner: If the film is very dirty or stained, you can use a special cleaner designed for polycarbonate, such as Novus #1 or Brillianize. Spray the cleaner onto the film and wipe it gently with a soft cloth. Do not use abrasive cleaners, solvents, or window cleaners, as they may damage the film.
- Polish with a soft cloth: If the film has minor scratches or scuffs, you can polish it with a soft cloth to restore its shine. You can also use a special polish for polycarbonate, such as Novus #2 or Brillianize Polish. Apply a small amount of polish to the cloth and rub it gently on the scratched area in a circular motion. Wipe off any excess polish with a clean cloth.
- Protect from UV rays: Polycarbonate films have natural UV protection, but they may still degrade over time if exposed to direct sunlight for long periods. To prevent this, you can apply a UV-resistant coating or film to the surface of the polycarbonate. This will extend its lifespan and prevent yellowing or cracking.
Polycarbonate films can be stored and handled using simple and gentle methods and materials. Some of the common ways are:
- Store in a cool, dry, and dark place: Polycarbonate films should be stored away from direct sunlight, heat sources, and moisture. Ideally, they should be stored at a temperature of 10°C to 21°C and a relative humidity of 30% to 50%. They should also be protected from dust, dirt, and pollutants.
- Use protective enclosures: Polycarbonate films should be stored in suitable containers that provide physical support, light blocking, and dust prevention. They can be stored in cardboard boxes, metal cans, plastic cases, or archival envelopes. They can also be stored in PVC-free plastic sleeves or pages that can fit into binders or folders.
- Handle with care: Polycarbonate films should be handled with clean hands or gloves to avoid fingerprints, oils, or acids. They should also be handled by the edges and not by the surface to avoid scratches or abrasions. They should not be bent, folded, creased, or cut unless necessary.
- Avoid chemical exposure: Polycarbonate films should not be exposed to any chemicals that may damage them, such as alcohol, ammonia, aromatics, solvents, or acids. They should also not be cleaned with any harsh cleaners or abrasive materials. If cleaning is needed, use a mild soap and water solution and a soft cloth.
To choose the right thickness and size of polycarbonate films for your project, you need to consider several factors, such as:
- The purpose and function of the film: Different applications may require different levels of strength, stiffness, flexibility, transparency, or durability. For example, if you need a film for a label or a graphic overlay, you may choose a thinner film with good printability and formability. If you need a film for a light fixture or a lens, you may choose a thicker film with good light management and optical properties. If you need a film for a security card or a bulletproof glass, you may choose a very thick film with high impact resistance and tamper evidence.
- The environmental conditions and exposure: Different environments may affect the performance and lifespan of the film. For example, if you need a film for an outdoor application, you may choose a film with good UV protection and weather resistance. If you need a film for a high-temperature application, you may choose a film with good heat resistance and thermal stability. If you need a film for a chemical application, you may choose a film with good chemical resistance and flame retardance.
- The processing and fabrication methods: Different methods may require different specifications of the film. For example, if you need to cut, die-cut, emboss, or thermoform the film, you may choose a film with good workability and dimensional stability. If you need to print, bond, or laminate the film, you may choose a film with good ink adhesion and surface finish.
