Custom Four Corner Buffer Insert Panel Dieline Generator

Add targeted protection where boxes need it most. Our Custom Insert Panel with Four Corner Buffer Dieline Generator helps packaging designers, brands, and printers create accurate, print-ready inserts that cradle products with integrated corner cushioning. Configure insert dimensions, buffer size, and board thickness to lift items off the corners, keep them centered, and reduce damage from drops, shocks, and corner impacts.

This online tool automates complex corner buffer geometry, cutting manual CAD work, sampling time, and material waste. Use it for fragile, premium, or high-value products where corner crush and product shifting are a concern. Export clean dieline files to share with your packaging supplier, speed up approvals, and ensure consistent, professional insert panels with four corner buffers for e-commerce, retail, and subscription packaging.
