The Comparison and Matching of Low Density Polyethylene Plastic Bags by Infrared Spectroscopy
Low density polyethylene (LDPE) is by far the most common polymer film material. Bags and pouches made from LDPE are readily available and are being used as packaging by peddlers of illegal drugs and by other criminals. It is therefore important that an investigator have ways of comparing LDPE bags used in the commission of a crime with bags belonging to a suspect.
