Polycarbonates
are transparent thermoformable materials noted for their superior impact
resistance. This quality of the material makes them the ideal materials
for protection against vandalism or outside forces of nature.
Remarkably, polycarbonate sheet is also highly malleable.
Polycarbonate films are films based on polycarbonate and can be
processed without losing their original shape or durability. They are
transparent with two glossy surfaces and offer excellent thermal
stability. They offer excellent dielectric properties and good printing
performance. They act as an easy substrate to print, giving excellent
ink adhesion without pre-treatment.
They are available in wide variety of finishes, textures and gauges.
They offer high transmittance, excellent surface uniformity and ease of
processing. They offer superior mechanical, electrical and optical
properties for applications requiring high clarity, improved heat
resistance or reduced glare. They are hard and resistant to chemicals
and abrasion.
Surface Finishes
Polycarbonate films fall into three broad categories:
- Polished Grade Polycarbonate Film - They
offer light transmission through all gauges. These films are
available in custom colors and the surface can be embossed or
selectively textured by a screen printing for aesthetic purposes.
- Textured Grade Polycarbonate Film - They are
anti-reflective and control light diffusion. They are easy to
process and can also be embossed. They help to conceal scratches.
- High Performance Grade Polycarbonate Film- They
offer exceptional resistance to attack by chemicals and to abrasion,
making them suitable for a wide range of applications. They feature
a proprietary UV stable coating, which brings long lasting outdoor
performance to a wide range of graphics applications.
Applications: Polycarbonate films and packaging
Typical applications include instrument panel overlays, thermoformed
medical packaging, mousepads, automotive dials, automotive control
panels, keypads, chip packaging, menu boards, and film insert molding.
They are ideal for screen or offset printing, bringing important
benefits to a wide range of graphics applications. They are ideal for
display windows. Polycarbonate films can be thermoformed into packages
of any desired shape and sizes. These films provide excellent physical
properties and good clarity required for medical product packaging. The
superior clarity of this type of film is that it allows surgeons and
other medical professional to easily identify and verify package
contents, thereby providing an additional degree of quality control.
Polycarbonate films are good for packaging, especially medical packaging
because of the following reasons:
- Polycarbonate film excels in optical clarity.
- These films have excellent printability.
- They have high strength and dimensional stability.
- They offer high temperature resistance.
- They have superb workability for secondary processes like
die-cutting, embossing and thermoforming. They come in a variety of
surface finishes like gloss, matte, velvet, and even suede.
- Special properties that can be imbibed into polycarbonate films
are like colors, enhanced weather resistance, chemical resistance
and flame retardance.
