Start in Just a Few Steps
Best Uses for Seal End Boxes
Seal end boxes are designed for secure, tamper-resistant packaging. The ends are sealed during assembly, creating a stronger, more protective structure than tuck-end styles. Because the box must be opened by breaking the seal, it is a great choice for products that require safety, hygiene, or clear evidence of first opening.
Seal End Boxes for Tamper Evident Packaging
This style is widely used for chocolate and confectionery, tea and coffee products, nutraceuticals, pharmaceuticals, and personal care items. The sealed ends protect contents from dust and handling while giving consumers confidence that the product has not been opened.
Seal End Boxes for Shipping Strength
With sealed panels, the box is more resistant to crushing and shifting in transit. It works well for heavier items or for retail products shipped individually through e-commerce channels.
Seal End Box Gluing and Assembly Tips
Most seal end boxes are finished with varnish or lamination. Before production, please confirm that your packing facility is using an adhesive that bonds well to varnished or laminated surfaces. If needed, we can leave the glue flaps unvarnished and unprinted to ensure a stronger seal. Just let us know in advance so we can set this up correctly during manufacturing.

What Our Customers Say
Real stories from customers who worked with us to create custom packaging they’re proud of.
I couldn’t be happier with my experience working with QinPrinting. From start to finish, their team was responsive, professional, and truly invested in helping me bring my vision to life. I printed my first edition of a 58-card deck (complete with a custom magnetic box) and the results were stunning.
The color accuracy, matte finish, and premium cardstock all exceeded my expectations. Every detail shows real craftsmanship. The communication was outstanding too; they provided clear updates, design templates, and guidance at every stage.
What impressed me most was how personal the process felt. Even though they’re a large-scale printer, they treated my small-batch creative project with care and respect.
If you’re looking for a reliable, high-quality printer for custom card decks, packaging, or creative projects, I can’t recommend QinPrinting enough. I’ll absolutely be printing with them again for my next production run!
Susan!!!! These books are SOOOOOOO beautiful! I don't think we could have dreamed how joyful it would be to open the box and find such care for and beautifully printed books. This was a special day -- we hope to have many more like it.
Thank you for fielding so many questions. Your patience with us (well, me) was so kind. You and your team have gone above and beyond for us.
Gratefully,
MAC
Most of all, we are so grateful for Nelson’s support throughout the entire process. He was consistently helpful, communicative, and detail-oriented — truly a pleasure to work with. Every step was made easier thanks to his guidance and care. We couldn’t have asked for a better experience!
Highly recommend both the product and working with Nelson. We’ll definitely be back for future projects.
A special thanks to Nelson, who went above and beyond by sending us videos of the printed books and samples before shipping to ensure everything was perfect. His attention to detail and dedication gave us great peace of mind.
We had a children’s book printed and the final product was absolutely beautiful. The print quality, vibrant colors, sturdy binding, and professional packaging exceeded our expectations. Delivery was timely and the pricing was very competitive, especially for the high level of quality and service we received.
We were so impressed that we didn’t hesitate to place a second order with them and once again, everything was flawless.
If you're looking for a reliable, high quality, and customer focused printing company, QinPrinting is the one to go with. Highly recommended!
