Abstract
Carrier stock formed from a single sheet of resilient polymeric material, such as low density polyethylene, and severable into individual carriers with integral handles along lateral edges. Integrally joined band segments define container-receiving apertures. Perforate lines, along which such stock is severable, divide certain cross segments into half segments. Each half segment has an aperture-defining edge configured with a nub countering tendencies of such half segment to neck down or to break.
