Varnish

A self-sealing poly mailer printed with content that changes bag to bag, a name, a message or an order reference, rather than one design repeated across the run. Orders start from 100 units.
“Personalised” and “custom printed” get used interchangeably, and for a poly mailer they are genuinely different jobs. Worth being clear which one you actually need before anything else on this page.
A custom-printed mailer carries one design, printed the same way on every bag in the run: your logo, your colours, done once and repeated. A personalised mailer carries content that changes from bag to bag within the same run, most often a recipient’s name, an order number, or a short individual message. That second job needs the actual data alongside the artwork: a name list, an order file, whatever is meant to vary. It is quoted differently from a single repeating design, because the press has to vary the printed content unit by unit rather than run one plate across the whole batch. Wanting your logo on every bag the same way is the simpler custom-branding route, not personalisation. Say so at the quote stage, and you won’t pay for a job you don’t actually need.
A poly mailer is a lightweight polyethylene film bag with a self-sealing adhesive strip, built to protect contents from moisture and knocks in transit without the bulk of a box. It suits soft goods, apparel and anything that doesn’t need rigid protection. Offset, digital or screen printing all apply. Pantone references and CMYK values can be used to manage colour consistency, subject to normal variation caused by the chosen board, ink, coating and production method. That matters more here than usual, since colour needs to hold steady across many individually varied prints rather than one repeated plate.
Orders start from 100 units. That figure applies per design. A run of many individually varied names or messages still counts as one design. Standard production takes 6 to 8 business days after approval. UK delivery is free. There are no setup fees. Design support is free. It’s worth using specifically to set up the variable-data template correctly before the run starts. A digital 3D mock-up is free.
Where every bag can carry the identical design and nothing needs to vary unit to unit, the simpler and cheaper route is Custom Poly Mailers With Logo. For clothing and soft goods specifically, Clothing Poly Mailers and Apparel Shipping Bags are built for that use. A frosted, semi-opaque finish rather than a fully printed one sits under Custom Frosted Poly Bags. The wider range is under Poly Mailers.

Real feedback from customers who trust us with their custom packaging.
Clear answers about ordering, artwork, production, materials and delivery.
Both. The artwork sets the fixed design elements, and a data file (names, order references, or whatever is meant to vary) supplies the part that changes bag to bag. Send both together and we'll confirm the format that works.
It's a different production process, since the press varies content across the run rather than repeating one plate, so yes, it typically costs more than a single fixed design at the same quantity. If every bag can carry the same design, standard custom branding is the cheaper route.
An unlaminated paperboard construction may be easier to process through suitable paper-recycling streams than a heavily laminated alternative. That comparison is about board, though, and a poly mailer is nothing of the kind: it's a flexible film. Most standard kerbside schemes won't take it despite it being technically recyclable, because soft plastic runs through a different collection route entirely, usually a supermarket or high-street drop-off point rather than the bin at home. Mixing one into ordinary kerbside recycling by mistake is a common way to contaminate a batch. Final recyclability depends on the full material and finishing specification and the facilities available locally.
Orders start from 100 units. A run of varied individual names still counts as one design against that figure. Standard production takes 6 to 8 business days after approval.
