Features • Prolonged exposure to sunlight or hot caustics will cause backing to become
brittle and lose tensile strength.
• Thin, high strength polyester film helps reduce failures due to breakage while
meeting low caliper requirements.
• Chemical and solvent resistance to help reduce rejects produced from chemical
and solvent attack.
• Abrasion resistant to help protect surface from abrasion and rough handling.
