A tubular casing (10) for location around a food product (in particular, a meat product) prior to cooking or curing, and which has a substantially transparent appearance when said food product is located therein, which comprises a knitted tubular portion (11) produced in continuous lengths from translucent yarn, the wall of said knitted tubular portion (11) having a stretchable loop-style stitching pattern which results in greater than 50 % open area when the stitches are fully extended but which is substantially impermeable to said food product, and circumferential elastic reinforcement threads (12) secured to and spaced along said knitted tubular portion that become taut while said knitted tubular portion remains stretchable as said food product is located within said knitted tubular portion so that said circumferential elastic reinforcement threads (12) press into the surface of said food product. This produces a distinctive surface pattern, with the food product protruding within bands (14) between the circumferential restrictions.
