Water Soluble Film for
CONCRETE FIBER Packaging

  • INFHIDRO supplies PVA based water soluble film, also known as PVOH, under the HIDROFIBER® brand, specifically engineered for the packaging of concrete reinforcement fibers. The dissolvable film for concrete fiber packaging allows pre-dosed fiber insertion directly into concrete mixers without manual opening, reducing dust and ensuring uniform dispersion.

Packaging for Macro Synthetic Structural Fibers

  • HIDROFIBER® PVA based film is designed to wrap continuous strand and cut-length macro synthetic fibers used in structural concrete applications. The film provides the mechanical strength and adhesion required during wrapping and cutting. 

  • Once introduced into the concrete mixer, the film dissolves completely under mixing conditions, allowing uniform fiber distribution without manual opening or material waste.

  • The film is available in widths ranging from 5 cm to 20 cm and thicknesses between 20 and 30 microns. Additional widths and customized thicknesses can be supplied upon request to meet specific packaging line requirements.

Water Soluble Film for Concrete Fiber Packaging (HIDROFIBER)

Water Soluble Film for Concrete Fiber Packaging in Action

Technical Specifications of the HIDROFIBER® Water Soluble Film Range

Series Model Application Format / Use Thickness Dissolution Time
Premium (P) PBF Structural synthetic macrofibers Continuous roll film 20 μm 165s (15°C)
Standard (C) CBF Structural synthetic macrofibers Continuous roll film 22 μm 360s (15°C)

The film in roll format (PBF / CBF models) is designed to feed automatic continuous wrapping machines. The equipment wraps the synthetic macrofiber filament and cuts it to the specified length, creating compact bundles for direct addition to concrete.

The main difference lies in their mechanical performance and cost: the Premium PBF series (20 μm) is a high-end option offering greater elasticity and wrapping tack at a higher price point, whereas the Standard CBF series (22 μm) is a more economical alternative ideal for optimizing budgets in projects with standard requirements.

No. Polyvinyl alcohol (PVOH) completely solubilizes in the mixing water without affecting the workability, setting time, or final mechanical strength of the structure.

Yes, full regulatory documentation—including official REACH/SVHC test certificates (SGS), Safety Data Sheets (MSDS), and Technical Data Sheets (TDS)—is supplied upon request.

Packaging for Micro Reinforcement Fibers

  • For micro polypropylene, mineral, metallic and cellulose reinforcement fibers supplied in small formats, INFHIDRO offers pre-dosed packaging solutions using PVA based dissolvable bags or water soluble paper bags for general packaging.

  • Both solutions allow precise dosing and reduced dust exposure while maintaining compatibility with concrete batching processes, ensuring consistent fiber dispersion during mixing.

  • Standard dosing formats are available, with customizable bag dimensions and material thicknesses to match specific batching requirements.

Water Soluble Bags for Concrete Fiber Packaging in Action

Technical Specifications of HIDROFIBER® Water Soluble Bags

Series Model Application Format / Sizes Thickness Dissolution Time
Standard (C) CBH-COLD Microfibers (PP, mineral, cellulose, metallic) Bags (various sizes) 20 μm 260s (15°C)

Microfibers (polypropylene, cellulose, mineral, or metallic) are packaged in exact doses inside the water-soluble bags. The closed bag is thrown directly into the batching mixer or ready-mix concrete truck drum, eliminating the need for manual opening or fiber handling.

Upon contact with water under the mechanical action of mixing, the bag breaks open and begins dispersing in approximately 18 seconds. The time required for full dissolution at the batch plant or job site depends directly on the water content of the mix and the friction generated during mixing.
