Buns Liners
Soft-touch liners that prevent sticking and soaking.

Buns aren’t just delivered in boxes — they’re served, handed out, eaten on the go. Bosger’s buns liners are designed to cover all those scenarios. Whether used as a base in a delivery box, as a serving square on a plate, or folded like a napkin for takeaway, these liners offer clean, food-safe contact between the bun and hands, surfaces, or packaging.
Made from grease-resistant, soft-touch paper-like mineral film, our PFAS-free liners keep oil and crumbs contained without staining or sticking. Perfect for brioche, sandwich buns, burger rolls, and more, they preserve texture while enhancing presentation. Cafés, bakeries, and fast-food chains use Bosger liners to upgrade their product look, improve hygiene, and add a thoughtful layer to the experience.
Available in rolls or ready-cut sheets, our liners are eco friendly, printable, and compatible with automated or manual packaging. Add your logo or pattern for a branded touch that reaches customers in every bite. From counter service to delivery bags — Bosger helps buns travel well and arrive beautifully.
