Microdot Roller

A microdot roller is a specialized roller used to apply very precise, controlled amounts of adhesive, coating, or ink using a micro-pattern of raised dots. These rollers are designed for precision coating or bonding, particularly where uniform distribution and material savings are important.

Common Applications

Adhesive Applications

  • Industries: Packaging, automotive, hygiene products, textiles.

  • Purpose: To apply hot melt or pressure-sensitive adhesives in controlled dot patterns instead of a continuous film.

  • Benefits: Saves adhesive, improves bonding performance, and allows breathability (important in hygiene products like diapers).

Hygiene Product Manufacturing

  • Industries: Diapers, sanitary napkins, adult incontinence products.

  • Purpose: Applies adhesive in microdot form to nonwoven fabrics for bonding layers.

  • Advantage: Ensures soft feel, flexible bonding, and efficient material use.

Lamination and Bonding Process

  • Used for: Laminating film to paper, fabric to foam, or other multi-layer constructions.

  • Purpose: Uniform adhesive distribution ensures consistent bond strength without over-saturation.

Label and Tape Manufacturing

  • Used for: Coating the back of label stock or double-sided tape.

  • Purpose: Precise adhesive placement with minimal waste.

Medical & Technical Textile

  • Used for: Bandages, breathable medical adhesives, wearable sensors.

  • Purpose: Applies adhesive or functional coating while maintaining breathability and flexibility.

Key Features

Surface is engraved with tiny, regularly spaced dot structures.

Allows for metered application of viscous materials.

Often used in hot melt adhesive systems.
