Ecommerce packaging is a vital brand touchpoint.
Unlike retail boxes, an ecommerce mailer is the first physical interaction a customer has after placing an order. The mailer must protect the product, survive distribution, communicate quality, and create a positive unboxing experience. SFL achieves this.
Single face lamination, commonly called SFL, can help brands create ecommerce mailers that combine structural performance with a more refined printed appearance. By laminating a printed paperboard sheet to corrugated material, SFL can provide the strength needed for shipping while supporting the graphics and finishes associated with premium retail packaging.
For brands that want to elevate their direct-to-consumer presentation without relying on a separate shipping carton and retail box, an SFL mailer can offer an effective middle ground.
"When outer transit protection and inner unboxing visuals are engineered together, SFL mailers eliminate unnecessary secondary boxes."
Strength Meets Premium Presentation
A standard corrugated mailer is durable but industrial. SFL provides the compression strength and cushioning benefits of corrugated material while creating a smoother exterior surface for printed graphics. This allows the package to function as both a shipping structure and a branded presentation piece.
Extension of the experience to the interior is highly effective. The inside of an SFL mailer can include welcome messages, usage instructions, or QR codes that guide unboxing. This creates a cohesive presentation compared to a plain brown box.
Premium SFL mailer layout features:
- Branded Exteriors: Clean brand colors, logo alignments, campaign art.
- Branded Interiors: Patterns, instructions, social media prompts.
- Fluting Protection: E-flute or F-flute microcorrugated cushion barriers.
- Integrated Retention: Platforms and custom partitions holding parts in place.
- Closing & Opening: Pull tabs, tear strips, reclosable adhesive tapes.
