What Is TPU?

Premium TPU, not cheap plastic.

What TPU is

Every Sencieres bag is made from TPU (thermoplastic polyurethane) — a soft-touch, high-gloss material that gives that signature glass-like, translucent finish. It holds a clean, structured shape and feels substantial in the hand.

Why it matters

TPU is more durable and more UV-stable than the PVC used in disposable jelly bags. It resists yellowing, doesn't turn brittle in the cold, and contains no plasticisers to migrate out and leave the surface sticky over time. It looks expensive because the material is genuinely better.
