​Clamshell rigid boxes – Premium packaging solution by Khang Thanh

A clamshell box is a high-end, rigid box with a book-style opening designed for protection and elegance. It consists of an outer cover and an interior base for easy opening and closing. This structure makes it perfect for premium products like gifts, books, cosmetics, jewelry, and electronics. At Khang Thanh Packaging, we craft rigid clamshell boxes that are available in custom sizes and shapes to match your brand’s identity.

Premium paper materials for clamshell boxes

At Khang Thanh, we use high-quality paperboard to create durable, refined rigid boxes. Specifically, the core is made from 1mm to 5mm (0.04 to 0.2 inch) greyboard (chipboard), ensuring strength and longevity. 

The outer surface can be wrapped in kraft, coated, special art, or metallic paper, providing various textures and finishes to enhance the luxurious feel. We also offer recycled and biodegradable paper options with FSC and other industry-standard certifications to support sustainability. 
 

Customization and printing options

We offer offset printing with CMYK, PMS and spot color printing to ensure vibrant and precise designs. Compared to other printing methods, offset printing delivers sharp details, consistent colors, and cost efficiency for bulk orders, making it the best choice for large-scale production.

We provide premium finishing options such as gloss or matte lamination, spot UV or varnish, embossing, debossing, and hot foil stamping to enhance your packaging further. Additionally, die-cutting and gluing ensure that each box is produced precisely to meet your needs.
