The utility model discloses a paper damp-proof packaging
barrel and belongs to the technical field of packaging containers. Comprising a
barrel body and a
barrel cover, a barrel body anti-deformation hoop is combined on the outer wall of the upper end of the barrel body around the periphery of the barrel body, and the lower surface of the barrel cover makes contact with the upper surface of the barrel body anti-deformation hoop; a barrel body bottom plate supporting and positioning folded edge is arranged at the bottom of the barrel body in the direction of a barrel
body cavity in a folding and unfolding mode, a barrel body bottom plate is supported and positioned on the barrel body bottom plate supporting and positioning folded edge, and a barrel body bottom plate
moisture-proof film is combined on the surface of the side, back to the barrel
body cavity, of the barrel body bottom plate. The periphery of the barrel body bottom plate damp-proof film extends to the side, back to the barrel
body cavity, of the barrel body bottom plate supporting and positioning folded edge. The upper edge of the barrel cover is folded and unfolded to form a barrel cover folding edge, the
peripheral edge part of the barrel cover plate is fixed with the downward side of the barrel cover folding edge, the upward side surface of the barrel cover plate is combined with a barrel cover plate
moisture-proof film, and the periphery of the barrel cover plate
moisture-proof film extends to the upward side surface of the barrel cover folding edge. The stacking requirement of the required layer number is met; moisture invasion is avoided, and raw materials in the barrel body cavity are protected.
