Physical evidence obtained at crime scene is important basic evidence in forensic science. In such
examination along with classical methods, instrumental analysis plays a major role. Very few studies
have been performed for cardboard comparison as physical evidence with reference to forensic examination. Examination and
comparison of cardboard found in murder case was successfully performed using thermal methods of analysis. The results
were also matched with control samples. The analysis is found to be helpful in identication and linking of physical evidences
at crime scene. The results obtained from the simultaneous thermal analysis of cardboard seized at crime scene and company
ofce showed that all the three layers in cardboard show similar thermal properties and differences found in the thermal
properties were due to their treatment in making originating from binder in cardboard making. The adhesive material used in
preparation of corrugated card board box results in exothermic degradation peak while endothermic peak was observed for
corrugated card board box without adhesive material. The differences in results are found out with help of control sample as
well as simulated study.
