FAQ
Q: What makes the sleeve-tray design better than a standard tuck-top carton?
A: The sleeve-tray design creates a premium two-step reveal — slide off the outer sleeve to present the product on the inner tray. It’s widely used for luxury confectionery because it elevates the perceived value and provides display functionality at retail.
Q: Can the window be customized to a shape matching my logo or product?
A: Yes. We can die-cut windows in any shape — logo silhouettes, product outlines, hearts, stars, or custom shapes. Complex shapes may require a minimum order of 3000 units to amortize die costs.
Q: Is the PET window recyclable?
A: Standard PET windows are technically recyclable but should be separated from the paperboard. For fully compostable packaging, we offer PLA (polylactic acid) windows derived from corn starch that meet EN 13432 composting standards.
Q: How does the sleeve stay in place during shipping?
A: The sleeve-tray fit is precision-engineered with controlled friction. For shipping we recommend a shrink-wrap overwrap or a small clear adhesive dot seal, both of which we can apply in-line.
