Most rigid plastic jars are made by molding plastic resin pellets. At a high level, resin is prepared, dried when the material requires it, melted, pushed into a mold, cooled, ejected, trimmed if needed, inspected, and packed. Caps, liners, and sealing discs are made or selected separately by neck size and finish. Taral's catalog and line drawings confirm materials, sizes, neck finishes, and dimensions, but the exact production process for each SKU should be confirmed with Taral if it matters to the order.
