PVC Backing Card for Lateral Flow Test Strips is a rigid white PVC sheet used as a backing/substrate during rapid test (lateral-flow) strip assembly.

This type of backing card is commonly used in colloidal-gold and other lateral-flow formats to support membranes and pads, helping improve handling and keeping strip dimensions consistent. The sheet includes knife-scored guide lines to support repeatable cutting workflows.
