Carrefour has introduced a new bag to package potatoes. Called the Vertisac, this new bag is made of plastic material and manufactured in LDPE by means of a co-extrusion process. This manufacturing process enables a thinner yet more resistant LDPE film to be produced. The new potato bag weighs 20,5 grams, or 3 grams less than the previous bag. The introduction of this new bag follows previous adaptations that had already reduced the weight of the packaging bag for potatoes.
