Abstract
Abstract A cardboard container with anti-slip property is disclosed. It has a synthetic resin layer formed of thermoplastic synthetic resin fine hollow particles of 5 to 50 microns in diameter containing one or more of an inert gas, an active gas, a nonvolatile liquid and a volatile liquid coupled by a synthetic resin component exhibiting an action of a binder. The synthetic resin layer is formed on the outer surface of at least one of bottom and upper walls of the container on the entire surface or a portion of the surface as a spot, a lattice or a stripe. Thus, particular means are not necessary to handle the cardboard container such as packing with a film or binding with bands after stacking a plurality of containers. The anti-slipping effect remains even after the stacked containers are sorted and transferred.
