T-shirt (vest) bag

The t-shirt or vest bag is the world's most manufactured bag: an HDPE tube with die-cut shoulder handles whose silhouette names it. Engineering-wise it is remarkable — a 12–25 µm film carrying several kilograms, because vest handles load the film in pure tension.

Supplied blocked (on a header for checkout racks) or loose, plain, tinted or printed. Specification points: dimensions including gusset, gauge, handle reinforcement, block format, print. Recycled HDPE runs well in vest film. Regulatory context matters at retail: the UK single-use carrier bag charge applies, so buyers position either thin charged bags or heavier reusable "bags for life". Classified HS 3923.21. In this corridor, Turkish film plants supply the full retail matrix with recycled-content options and batch declarations.
