PVC wood-plastic inner co-extrusion door pocket

The utility model provides a PVC wood-plastic inner co-extrusion door pocket, and relates to the technical field of building materials. The cable comprises an outer co-extrusion layer and an inner core co-extrusion layer which are formed by fusion co-extrusion, wherein the toughness of the inner core co-extrusion layer is larger than that of the outer co-extrusion layer; clamping grooves are formed in the two sides of the outer-layer co-extrusion layer respectively, and the outer-layer co-extrusion layer is fixedly connected with the adjacent door pocket line through the clamping grooves; the inner core co-extrusion layer is located in the outer layer co-extrusion layer and is at least arranged on the side, close to the lock hole edge or the hinge edge, of the outer layer co-extrusion layer. The toughness and strength of the lock hole edge and the hinge edge of the whole door pocket are improved, later repeated opening and closing vibration is resisted, the overall nail-holding power is enhanced, and then con
