Film Facestock Characteristics
Flex. Modulus . . . . . . . . The measure of a film’s conformability
Tensile Strength . . . . . . . The force required to break a film
Elongation . . . . . . . . . . . How much a film will stretch before it breaks
Dimensional Stability . . The ability of a film to resist growth or shrinkage when exposed to various environments
Chemical Resistance . . . The ability of a film to withstand exposure to various solvents
Surface Energy . . . . . . . The characteristic of a film which indicates how easily an ink or coating will adhere and wet-out
Opacity . . . . . . . . . . . . . . The measure of the amount of light that cannot pass through a film
Stiffness . . . . . . . . . . . . . Measurement of a film’s rigidity
Tear Strength . . . . . . . . . The measurement of a film’s toughness or resistance to tearing or splitting

Film Surface Treatments
> Corona Treatment Altering the surface characteristics by exposing the surface to a high voltage
discharge (corona) resulting in an increase in surface energy (dyne level).
» Usually requires 38-42 Dynes to print and achieve good ink anchorage
» Will dissipate with age and timing varies with film
» Do not over treat as this will cause the print to washout or result in poor ink anchorage
issues
> Topcoating A chemical coating applied to the surface to improve ink and toner anchorage.
» Various types available for different uses
» The right one is needed to meet application needs and insure that the product
converts well
> Print Treatment A proprietary chemical coating applied by the manufacturer during the film
making process.
» Unique to polyesters

PS 101 – Preparing for Your Success Confidential—For Internal Use Only
Film versus Paper
Paper
• Wider variety of facesheet options
• Easier to manufacture a custom
product
• Less expensive
• More friendly to various printing
technologies
• May wrinkle
• No water resistance
• Decrease durability (solution is to
add an overlaminate
Film • Offers water and moisture
resistance
• Offers durability to UV, heat,
chemical, abrasion, and autoclave
exposures
• Long lasting
• Offers tear resistant or tamper
evident properties
• Flexible/Conformable - good for
squeeze applications
• Can be used as a resealable closure
system for flexible packages
• Offers “no label look” on clear
containers
• Typically more expensive
