Water-resistant adhesives and barrier coatings for paper straw production. Achieve 3+ hour water resistance and zero sogginess in cold beverages.
Guide A practical regulatory explainer for packaging teams: what FDA 175.105 covers, when 176.170 matters, where FCNs fit, and how to avoid treating one route as blanket approval for every food-contact application.
Guide A practical comparison for beverage brands: drink-life, sensory feel, line complexity, direct-contact compliance, sustainability tradeoffs, and where paper still needs stronger adhesive engineering to compete with plastic.
Guide A paper straw that survives service is built through tension control, winding speed, solids management, and the right water-resistant adhesive chemistry. This guide walks through the full process.
Case study A spiral-wound straw converter reduced immersion seam failures in pilot and production by qualifying a water-resistant adhesive route tuned to line speed, paper grade, and dry-tunnel conditions—without relying on excess coat weight.
