Varnish
A transparent finishing layer available in gloss, satin, or matte effects. It enhances the printed surface and adds an extra layer of visual appeal and light protection.
An ecommerce mailer box with its closure matched to how often this product line actually comes back. Orders start from 100 units.
Not every online order gets returned, and the closure that suits sending a parcel out isn’t always the one that suits taking it back.
A self-seal strip closes with a single peel-and-stick action, quick to pack and firm for a one-way trip, but it’s designed to be opened once rather than resealed cleanly for a second journey. Tuck-top and tab-lock closures fold or tab shut without that kind of single-use strip. The same box a customer receives can then be resealed and sent straight back for a return or exchange, with no extra tape and no separate returns box. Picking between them comes down to the product itself, not which closure looks more finished. A low-return line, a single small accessory, a food item, rarely needs the reseal, and self-seal is the simpler, faster pick for it. A high-return line, clothing sized by fit, anything ordered in more than one option, gets real value back in fewer replacement boxes and an easier return for the customer, and that’s where a resealable closure earns its place.
The board, the print and the standard commitments across the wider mailer range don’t change with the closure chosen. Matching the closure to the return rate is a decision made at the quote stage, not a different product line.

The wider range of colours, materials and specialist formats starts at Custom Mailer Boxes.

Real feedback from customers who trust us with their custom packaging.
Clear answers about ordering, artwork, production, materials and delivery.
Orders start from 100 units. Standard production takes 6 to 8 business days after approval.
Look at how many orders in a typical run actually come back, not just whether returns happen at all. A handful in every few hundred rarely justifies it. A steady share coming back most weeks, common with sized or multi-option items, usually does, since a replacement box costs more over time than choosing the resealable closure from the start.
No. The same fold-and-tab or fold-and-tuck close also suits an exchange or a warranty send-back, anywhere the customer needs to put the box back together without new tape.
It's a closure choice rather than a different production process, so it's raised at the quote stage alongside the standard order details, not treated as a separate product line.
An unlaminated paperboard construction may be easier to process through suitable paper-recycling streams than a heavily laminated alternative. Final recyclability depends on the full material and finishing specification and the facilities available locally.
