HANGU is a manufacturer of customizable hydrocolloid roll materials for OEM and ODM patch production. Our hydrocolloid rolls are designed for further processing into acne patches, blister plasters, hydrocolloid wound dressings, and a wide range of skin protection products.

The material combines a waterproof and breathable polyurethane (PU) film backing with a hydrocolloid adhesive layer containing sodium carboxymethylcellulose (CMC-Na) and medical hot-melt pressure-sensitive adhesive.

The hydrocolloid layer absorbs fluid and forms a soft gel upon contact with moisture. Its flexible construction also allows the material to be converted into different sizes and shapes for various applications.

HANGU supplies plain hydrocolloid master rolls, colored and printed roll materials, and die-cut hydrocolloid patches in roll form.

With customizable formulations, surface designs, roll dimensions, and converting options, our hydrocolloid materials help B2B customers develop products for different markets and application requirements.

Our hydrocolloid roll material features a three-layer construction:

Layer 1 — Waterproof & Breathable PU Film Backing

The polyurethane backing provides a flexible outer layer with waterproof and breathable properties, making it suitable for the development of different hydrocolloid patch products.

Layer 2 — Hydrocolloid Adhesive Layer

The functional layer contains CMC-Na and medical hot-melt pressure-sensitive adhesive. The hydrocolloid component absorbs moisture and forms a gel upon contact with fluid.

The formulation, thickness, and adhesive characteristics can be customized according to the intended product application.

Layer 3 — Release Liner

Silicone-coated release paper or PET release film protects the adhesive surface during storage, handling, and converting. Release liner materials can be selected according to customer manufacturing requirements.

• Fluid Absorption: Hydrocolloid components absorb fluid and form a gel.

• Waterproof & Breathable Backing: PU film provides a flexible protective outer layer.

• Flexible Construction: Suitable for converting into various patch sizes and shapes.

• Custom Formulations: Hydrocolloid composition and adhesive characteristics can be adjusted for different product development needs.

• Multiple Surface Options: Plain, colored, printed, glitter-effect, and holographic-effect designs are available according to customization requirements.

• Flexible Converting: Available as continuous roll material, printed rolls, or die-cut patch rolls.
