Rainbow® 310

Rainbow® 310 is our newest addition to the Rainbow® family of sustainable materials. Like all Rainbow® uncoated paper, Rainbow® 310 is made responsibly with an FSC-certified, recyclable, and archival dyed-through kraft substrate. With its extra sturdy 310gsm board weight and eco-friendly construction, this paperboard is a pro choice for knocking out folding cartons, boxes, hang tags, etc., making Rainbow® 310 the new heavyweight champion of the luxury retail packaging industry. Other creative applications may include photo matte, stationery, or arts and crafts. Choose from four standard stock colors or call to discuss custom color options. Sheet sizes are custom cut per order according to your specification.
