A groundbreaking water-soluble wrapping film is transforming the packaging of fibers used in concrete reinforcement, leveraging its exceptional adhesion and rapid dissolvability to drive the construction industry toward a greener, more efficient future. Made from polyvinyl alcohol (PVA) and other biodegradable materials, this film is specifically designed for wrapping concrete-enhancing fibers such as polypropylene, steel, and glass fibers. Its standout feature is its optimal adhesive property, which tightly wraps fiber bundles, forming a secure and stable package that effectively prevents loosening or moisture damage during transportation and storage, ensuring material integrity. Equally impressive is its water-soluble nature, allowing the film to dissolve quickly upon contact with water, breaking down into harmless substances. This eliminates the need for unpacking, as the fiber, still wrapped, can be directly added to a concrete mixer, where it dissolves and disperses uniformly, significantly boosting construction efficiency. Unlike traditional plastic packaging, this film requires no recycling, eliminating packaging waste, reducing on-site dust, and enhancing worker safety. Its adhesion and dissolution speed can be tailored to specific fiber types and construction needs, ensuring versatility. Widely used in ready-mix concrete production, on-site construction, and high-performance projects like tunnels and bridges, this film enhances concrete’s crack resistance and durability, delivering eco-friendly, high-efficiency solutions for modern construction.
