Running an e-commerce business means choosing packaging that protects your products while creating memorable brand experiences. With over 70% of D2C brands using corrugated boxes with custom branding, selecting the right mailer style has become crucial for business success.
A Roll End Tuck Front (RETF) mailer box is a specialized packaging solution featuring a self-locking closure system where the front panel tucks into the main body without requiring tape or glue. Also known as Roll End Front Tuck (REFT) boxes, these mailers include “Cherry Locks” – self-locking tabs that secure the front closure and dust flaps for additional protection, making them the #1 choice for subscription box packaging and e-commerce shipping.
Let’s explore why RETF boxes are revolutionizing packaging across industries and how they can transform your shipping strategy.
How Does a Roll End Tuck Front Box Work?
Understanding the assembly mechanism helps you appreciate why RETF boxes have become so popular among packaging professionals.
RETF boxes operate through a simple three-step assembly process that takes approximately 1 minute for most users, with experienced assemblers completing it in just 30 seconds. The design eliminates the need for additional adhesives or fasteners while providing secure product protection.
The assembly process involves three key stages. First, you fold the front and back panels upward, then fold the flaps on either end inward toward the center. Next, fold the side panels up and over the front and back flaps, tucking the tabs into the bottom slots to lock them in place. Finally, fold the lid down over the box, with two “ears” on either side of the front flap folding inward before the front flap tucks downward into the sides.
The Cherry Locks system creates the secure closure that prevents accidental opening during transit. These self-locking tabs maintain the box’s integrity throughout shipping while ensuring a smooth unboxing experience for customers.
The rounded flaps are engineered to smoothly tuck into the front of the main body, creating what industry professionals call a “treasure chest-like” opening experience. This design feature significantly enhances customer satisfaction and brand perception.
