Kraft Sample Bags
Kraft sample bags & envelopes are ideal for geochemical sampling. Due to using the 'Kraft' method of pulping, which removes lignin from the wood used, the end paper is substantially stronger than regular paper or board. This means that our range of Kraft sample bags can be used to store geological samples such as rocks, fossils, mineral specimens and soil samples, even when damp. Each bag has a top tie to prevent sample leakage & contamination.
