Why combine a sealed top with an auto bottom

A seal end auto bottom box pairs two practical features. The auto bottom, also called a crash-lock bottom, is pre-glued so the base snaps into place as soon as the flat carton is opened. The top uses seal end flaps that are glued closed after filling, which makes the box tamper-evident and stable on shelves. The result suits products that are heavier, packed in volume, or need a closure that shows if it has been opened.

SBS paperboard is the common choice for bright retail graphics, and kraft paperboard suits natural product lines. For dense goods such as powders, jars or hardware, a thicker board or E-flute corrugated adds support. A tear strip or perforated opening on the top lets customers open the sealed end easily. Because sealing is often done on packing lines, share how you plan to fill and close the boxes.

Treat the front as the shelf face, with clear product naming and brand mark, and use the side and back panels for usage notes, barcodes and any category details your product needs. If the box carries food or health products, labeling requirements vary, so check the current rules. Our team places your artwork on the dieline and sends a digital proof for approval.

FAQ

Custom Seal End Auto Bottom Boxes: questions answered

Still unsure? Ask a packaging specialist.

What is a seal end auto bottom box?

It is a folding carton with a pre-glued auto-lock base and a top that is glued or sealed closed after filling. The base locks open in one step, and the sealed top shows if the box has been opened.

What is the difference between seal end and tuck end boxes?

Seal end boxes are glued shut after filling, which makes them tamper-evident and stable for heavier contents. Tuck end boxes close with flaps that tuck in and can be reopened without damage. The right choice depends on the product and how it is sold.

Can seal end boxes have an easy-open feature?

Yes. A tear strip, perforated panel or zipper opening can be built into the top so customers open the sealed end cleanly. These are shown on the dieline and digital proof. An easy-open feature is helpful for products that customers use straight from the carton.

Are seal end auto bottom boxes good for heavy products?

The auto-lock bottom supports more weight than a tucked bottom, and the sealed top keeps the carton rigid. For very dense products, a specialist may suggest thicker board or E-flute corrugated. Share the weight and fill method so the board is chosen correctly.

How do I get a quote for seal end auto bottom boxes?

Send your product dimensions, weight, quantity, artwork and how you plan to fill the boxes through the quote form. A Vorex specialist replies with pricing and sends a digital proof before production. Mention whether you need a tear strip or window on the top.
