R. H. Plastics Limited—incorporated in 1976 and now a wholly-owned subsidiary of Poly Products Group—operates from the Kakuri Industrial Estate in Kaduna where the company specialises in plastic packaging, including PET preforms and bottles for beverage and edible-oil producers as well as jerrycans for lubricants; the group’s locations page lists the Kakuri factory address with two current mobile lines and the corporate email, while multiple directories corroborate the historic Kakuri address and additional contact numbers for customer service and sales.
