You can store both dry and wet soil samples without them tearing or loosing the contents. They’re primary use is for drying out and storing rock or soil and sediment samples or pulp from mineral exploration or mining projects or to hold for assay results.


A 125 x 250 mm kraft geochemical sample bag is the largest that we can supply. It is suitable for medium to large quantities of material or size specimens and can be sealed safely. Such as soil samples, milled RC chips or seeds. Each envelope opening has a wire closure, which can be folded down and secured.


Kraft paper is porous with high elasticity and high tear resistance, designed for packaging products with high demands for strength and durability. Hence why the paper has long since been used for geological sampling on drilling and mineral exploration projects. As the paper can hold up to sharp and pointed particles. In addition, the paper can be written on easily, using any pen, pencil or marker.


We can also provide custom printed envelopes. In black ink only, detailing sample numbers or layouts for easy data notations. Please contact us for further inquiries.
