Cover tapes for lateral flow and diagnostic applications
For more than 25 years, Kenosha has supported diagnostic manufacturers with high-quality adhesive materials, including precision-engineered cover tapes designed for consistent and reliable lateral flow performance.
Our cover tapes protect the test and control lines while allowing controlled air exchange and stable sample flow.
What are cover tapes in lateral flow tests?
Cover tapes serve as the protective top layer of a lateral flow assay, sealing the functional zones while non-interfering with capillary flow and reagent preventing evaporation.
Kenosha offers custom-printed cover tapes, enabling branding, labeling, or functional markings such as test line indicators, batch codes, or assembly alignment guides.
Printing can be individually adjusted per roll, providing unmatched flexibility for OEMs managing multiple product lines or assay variants.
Material options
Kenosha specializes in custom-printable films and laminates engineered for use as cover layers in lateral flow and diagnostic applications.
Our portfolio includes:
- Polymerfilms coated with medical-grade pressure-sensitive adhesives (PSA)
- Custom colors, finishes, and print designs, adjustable per roll for multi-SKU production
- High registration accuracy for fine alignment of printed features
Adhesive and lamination options
Kenosha’s adhesive systems are formulated for compatibility with membranes, conjugate pads, and backing cards, supporting stable assay performance.
Our lamination process ensures:
- Even adhesive distribution and uniform coating thickness
- Smooth, bubble-free bonding for consistent layer integrity
- Excellent chemical resistance and dimensional stability
All production steps follow a documented ISO 9001:2025 Quality Management System, ensuring traceability and medical-grade consistency.
Custom sizes and roll formats
Every diagnostic project has unique design and labeling needs. Kenosha supplies cover tapes:
- In custom widths, thicknesses, and roll diameters
- With variable printing per roll, enabling product differentiation, branding, or lot identification
- Cut to fit both automated and manual assembly lines
- Available in prototype and production quantities
This flexibility supports R&D development, validation, and large-scale manufacturing—all with consistent performance and reliable quality.
Quality & Certification
Kenosha operates under an ISO 9001:2025–certified Quality Management System, ensuring consistent quality, documentation, and process control across all manufacturing steps.
Each batch is fully traceable and tested for thickness, adhesion, and visual integrity, meeting the stringent quality expectations of the diagnostic and medical materials industry.
