• 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 abrasions and rough handling.
