Industry Leading DurabilityOur Laminated Vinyl labels are made of 4 mils thick, conformable vinyl. These vinyl labels have a 5-year outdoor warranty, but most labels last longer. Our labels are laminated for enhanced performance against moisture, chemicals, solvents, abrasion and fading. You can easily wipe off dust, dirt or grease and your graphics are protected. Unlike many other labels, our Warning - Doberman On Duty labels use industry-leading inks and not off-brand or other low-durability inkjet pigments that fade in a year or two.USA’s Oldest Label & Sign ManufacturerFamily owned since 1918, we take immense pride in our signage.
