This Nylon Heat Seal Fire and Explosion Evidence Collection tubular rollstock offers superior fire evidence collection and retention. This 12” wide tubular rollstock is made of nylon and is hydrocarbon free. Since it can be cut to any length, it allows for evidence of many different sizes to be collected and sealed for laboratory testing, as well as long-term storage while awaiting trial. This Nylon Heat Seal Fire and Explosion Evidence Collection Rollstock material is proven to be a preferred method of fire scene evidence collection. Nylon has long been the preferred material for collection and storage of evidence which may contain solvents found in accelerants. Unlike plastic bags, solvents will not break down the nylon material of our Nylon Fire and Explosion Evidence Collection rollstock, preventing the loss of flammables and hydrocarbons. This evidence rollstock virtually eliminates the potential for cross-contamination from propellant fumes. Safeguard arson evidence during lengthy storage periods. This rollstock can be closed in the field using cable ties or permanently sealed back in the laboratory using a heat sealer. The clear material allows the evidence to be seen without opening the bag and can be easily marked using standard marking pens or our Arson/Fire Debris Evidence Labels. For long term”stack-able” storage, our bags can be placed in metal evidence containers or cardboard boxes. 12” x 100', 1.6 mil thickness
