• Label affixed to cover is made of indoor/outdoor grade overlaminated polyester (B-302).
• B-302 is particularly suited for outdoor applications, and in harsh environments where excellent abrasion and chemical resistance is required
• Flexible material conforms to most surfaces while protected graphics hold up to harsh environments, abrasion, and repeated spills and cleanings
• Permanent, pressure sensitive adhesive forms a long-lasting bond to even the most difficult surfaces and shapes
