Non-Reinforced Asphaltic Kraft Paper Laminate (30/30/30)

Note: Federal Specification PPP-B-1055B (22 April 1989) is inactive for new design and maintained only for replacement purposes. Royco supplies this material specifically for customers who require legacy compliance or replacement stock. PPP-B-1055 Waterproof Paper is a non-reinforced asphaltic kraft laminate engineered for demanding applications where water resistance, durability, and chemical protection are essential. Constructed from two plies of 30 lb. kraft laminated with an asphalt core, this heavy-duty material—commonly known as 30/30/30—is widely used in construction, crate manufacturing, export packaging, and industrial surface protection. Its sealed asphalt core prevents penetration from water, overspray, and many cleaning agents, making it ideal for concrete curing, overseas crate waterproofing, crate lining, and hard-surface restoration where stone, tile, or polished surfaces require protection against harsh chemical cleaners.
