Can I print on both the sleeve and the box?
Absolutely. You can fully print both surfaces with distinct designs, allowing layered storytelling. However, it may increase the cost, especially if you are on a budget. For an optimized budget, get in touch with our sales team to discuss the best possible solutions.
Do sleeve mailers increase shipping costs?
They can add marginal dimensional weight. Optimization of size and minimizing void space helps keep shipping cost efficient.
Are sleeve mailer boxes strong enough for shipping?
Yes, when engineered with appropriate flute types and board grades. B-flute or double wall are recommended for heavier products.
What is the typical production lead time for mailer boxes with sleeves?
Production generally takes 10–14 business days after artwork and dieline approvals, depending on complexity.
