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 Arson Evidence Bags, preventing the loss of flammables and hydrocarbons. These bags 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. For long term "stackable" storage, our bags can be placed in metal evidence containers or cardboard boxes.
