GPA Announces New High-Temp Lightbox Material

GPA proudly announces the latest addition to their product line: Ultra Film® High-Temp Lightbox Material, which offers the affordability, sustainability and durability that make it the ideal choice for printing outdoor illuminated signage. 

Ultra Film® High-Temp Lightbox Material is an economical alternative to Polycarbonate and offers tremendous durability over Styrene. Created to meet the specific challenges of outdoor lightboxes, this material offers a high heat deflection rating and durability, so corners will not crack when folded and inserted into slots. From the coldest Minnesota winters to the hottest Arizona summers, GPA’s High-Temp Lightbox Material can withstand the harshest elements without cracking, warping or yellowing in the sun. It is perfect for applications such as point-of-sale (POS) signage, menu boards, and all other types of outdoor illuminated signage. 

This polypropylene-based polyolefin also qualifies as a #5 recyclable plastic and offers the added advantage of being curbside recyclable, provided the finished piece carries the #5 recycling symbol and the local municipality picks up #5 plastics. This new product makes it easier than ever for customers to make sustainable business choices. 

Ultra Film® High-Temp Lightbox Material is stocked in 28” x 40” sheets for offset and UV printing, with custom sizes available up to 48” x 90”. 

GPA is the premier source for specialty substrates and solutions for offset anddigital printing. Products include coated and uncoated papers, pressure sensitive and specialty papers, synthetic films and substrates exclusively engineered for HP Indigo presses.
