Lock products inside a fully enclosed protective box insert. Our Custom Two End Tab Closure Box Insert Dieline Generator creates accurate, print-ready inserts that form a complete box closed at both ends with tab closures. Place your product inside this inner box first, then load the finished insert into the primary packaging for an extra layer of protection.
Configure insert dimensions, tab style, and board thickness so the inner box fits your product snugly and sits securely inside the outer carton. This online tool automates end tab geometry and layout, reducing manual CAD work, sampling time, and material waste. Use it for fragile, elongated, or high-value products that need a full closed insert box for safer shipping, better handling, and a more premium unboxing experience.
