This 4 mil, 3-year outdoor durable white film with silver back acrylic adhesive for block out is ideal for flat-surface applications where blockout vinyl is required. The upgraded 90# double PE coated silicon liner is thicker and resists moisture better than other liners. Excellent for use in short-term promotional advertising, point of purchase, tradeshow displays and
outdoor signage. The 4 mil thickness is ideal for hand applications, really the strength of this product.
