What is a Roll End Tuck Top Box?

A Roll End Tuck Top (RETT) Corrugated Box is a type of shipping container that provides a high level of protection for products during transportation. These boxes are often used to improve the customer experience with ecommerce products. RETT boxes feature a unique tuck top closure, which creates a secure and tight seal that keeps items in place, preventing them from shifting or getting damaged during shipping. 

RETT boxes are commonly used for packaging and transporting delicate and fragile items such as glassware, electronics, cosmetics, and food products. They are also a popular choice for retail packaging, especially for products that require extra protection and support during display and transportation.

Overall, RETT boxes are a reliable and cost-effective packaging solution that offers superior protection and ensures that your products are safe and secure during transit.

Print Options

Flexography (also known as flexo) is a printing process that uses flexible relief plates made of rubber or photopolymer to transfer ink onto various substrates, such as corrugated, plastic films, and paper. It is a high-speed, cost-effective printing method that is suitable for printing on rough, porous, and irregular surfaces.

Digital print refers to a printing method that uses digital files such as PDFs, JPEGs, or TIFFs as a source for printing images or text. Digital print technology has revolutionized the printing industry by offering faster turnaround times, lower production costs, and the ability to produce high-quality prints

Lithography is a printing technique that uses a flat printing plate, a special kind of ink, and oil-based or water-based liquids to transfer an image onto a substrate. It produces high-quality, sharp and clear prints that are suitable for printing high-resolution graphics and text.

Graphic Design

Graphic design must reflect the brand identity and effectively communicate the brand’s message to customers.

Maximize product visibility by apply graphics with contrasting colors, bold text, and high-quality images.

The text used in the graphic design must be legible, both from a distance and close up. The font size, color, and style must be carefully selected to ensure that the text is easily readable

Have your graphics effectively utilize the space available on the display, including the sides and back, to maximize impact and exposure to the product.

Display relevant product information, such as product name, benefits, and features. This information should be presented in a clear and concise manner.

Create a design consistent with the brand’s overall design and marketing materials, ensuring a cohesive look and feel across all channels.

Flexible designing, allowing for the display to be easily updated as needed, without requiring a complete redesign.

View your product with a realistic 3-D rendering that is easily sharable. Renderings are ideal for reviewing display prototypes and enabling quick and cost effective edits and changes.


A gloss finish is a shiny and reflective surface that is achieved by applying a gloss varnish over the printed surface. This finish enhances the vibrancy and saturation of the colors and makes the printed graphics appear more eye-catching.

A matte finish is a non-glossy surface that has a flat and velvety texture. This finish provides a subtle and sophisticated look and reduces glare, making it ideal for printing products that require a professional look.

Spot UV is a printing technique that involves printing a clear UV varnish in specific areas of the printed surface to create a glossy texture on specific parts of the design. This finish adds depth and texture to the printed graphics and enhances the overall appearance of the product.

Embossing is a printing technique that involves creating a raised or recessed design on the printed surface by pressing a metal or plastic plate onto the surface. This finish creates a tactile experience for the consumer and adds dimension to the printed graphics.

Foil stamping is a printing technique that involves applying a thin layer of metallic or colored foil onto the printed surface. This finish adds a metallic shine to the printed graphics and creates a luxurious and eye-catching effect.

Litho lamination is a finishing process that involves bonding a printed piece to a thick layer of paper, plastic or film. This finish provides extra protection to the printed surface, makes the product more durable, and enhances the overall quality of the product.

There are many other finishes we can apply to your custom display such as a varnish, die-cutting, perforation, scoring, film lamination, creasing, hot foil stamping, blind embossing and others.

Strength & Thickness

Single wall corrugated material is the thinnest option, typically ranging from 200 to 500 microns in thickness. This option is suitable for lightweight products and provides a cost-effective solution for boxes.

Double wall corrugated material is thicker than single wall and typically ranges from 600 to 1000 microns in thickness. This option provides additional strength and stability to the box and is suitable for heavier products.

The most common ECT (Edge Crush Test) rating for custom corrugated boxes is typically between 32 and 44. ECT is a measure of a box’s strength and its ability to resist crushing under pressure, which is an important factor in determining the durability and protection of the packaged product during shipping and handling.

Burst ratings for corrugated boxes range from 200 to 400, with higher numbers indicating greater strength and durability. A burst rating of 200 is suitable for lightweight products, while a burst rating of 400 is recommended for heavier products.

RETT Box Structural Design

Structural design is a crucial aspect of corrugated boxes, as it affects the stability, strength, and overall appearance of the display. The following are key considerations for structural design in corrugated boxes:

Strength and Durability

A strong and durable corrugated box is vital for protecting products during handling and transportation. This requires careful consideration of factors such as material quality, size, flap and joint design, and the ability to withstand stacking and compression forces.


Size and Shape

The size and shape of a corrugated box are crucial for its strength, durability, and performance. It must be designed to support the product weight, resist compression forces, and allow for easy handling and transportation while ensuring material and production efficiency.


Cushioning and Protection

The cushioning material inside the corrugated box is a critical factor in its structural design as it must absorb shock and prevent product movement during transportation. The type, thickness, and placement of cushioning material are important considerations in ensuring optimal product protection.

Production Efficiency

Custom corrugated box design should optimize for efficient production, including ease of assembly, minimal waste, and reduced production time. Factors such as the use of efficient production techniques and the design of the flaps and joints can enhance the production efficiency of the design.


Sustainability is becoming an increasingly important factor in corrugated box structural design. Eco-friendly materials and designs are considered, with the use of recycled materials, eco-friendly coatings, and efficient production techniques being vital in reducing the environmental impact of the design.

Special Features

Custom corrugated boxes can be designed with special features, like handles or specialized openings, to meet the specific needs of certain products. These features are essential for protecting fragile or heavy items and ensuring easy access to the product.

Cherry Locks & Dust Flaps

Roll End Tuck Top (RETT) Corrugated Boxes can be customized with special security features such as cherry locks and dust flaps. These options provide added protection for your products during shipping and transportation, ensuring that your items arrive safely and securely at their destination.

Cherry Locks

Cherry locks are a special feature added to some packaging products, such as RETT boxes, to provide additional security during shipping and transportation. They consist of two interlocking tabs that are pressed together to create a tight seal, which prevents the box from accidentally opening and protects against tampering or theft.

Dust Flaps

Dust flaps are a protective feature that can be found in certain types of packaging, such as RETT boxes. They are an extra layer of corrugated that fold over the top opening of the box, creating a barrier to keep dust and debris out, and protecting the contents of the box during shipping and storage.
