Information is presented on the guideline for the forensic scientist in the examination and comparison of pressure-sensitive tapes.
Abstract
Pressure-sensitive tape consists of a flexible backing and pressure-sensitive adhesive (PSA), which when applied to surface bonds immediately at room temperature with slight pressure. The analysis and comparison of tape evidence in the forensic science laboratory can provide valuable information. The forensic examination of pressure-sensitive tape encompasses the determination of physical construction and chemical composition of tape products. This guideline provides an overview of techniques applied to the analysis to tape components. The guideline describes the areas of tape construction and classes, sample handling, and methods. This report is intended as an introductory guide for the forensic scientist when examining and comparing pressure-sensitive tapes. The methods and practices described have been peer-reviewed and are generally accepted within the forensic community. References
