Bags for taking, storing and transporting geological samples. Bags are made of different fabrics (according to customer requirements): calico and bleached, tarpaulin, tent canvas, double thread, diagonal, twill. The bags are sewed without a seam at the bottom to withstand the weight of geological samples. Side seams are made using the "double eversible seam" technology.
The neck of the bag is worked with a basting seam. The bags are necessarily provided with ties on one or both sides, with an indentation from the neck; ordinary or in a wader. The sizes of bags are from 100×150 mm to 400×500 mm. Core bags are produced in the size of 90×200 cm.
