1. A plastics film comprising a thin plastics sheet material, the thin plastics sheet material comprising: a plurality of quadra-arcuate apertures for holding a plurality of containers together, each container of the plurality of containers having a beading, the plurality of quadra-arcuate apertures
1. A plastics film comprising a thin plastics sheet material, the thin plastics sheet material comprising: a plurality of quadra-arcuate apertures for holding a plurality of containers together, each container of the plurality of containers having a beading, the plurality of quadra-arcuate apertures extending in at least a first direction of the plastics film;wherein each quadra-arcuate aperture of the plurality of quadra-arcuate apertures has a center and wherein edges defining each quadra-arcuate aperture has a geometry which comprises four tabs facing the center, each tab of the four tabs being defined by peaks spaced apart by troughs, each trough defining a root at a maximum point from the center;wherein the peaks and the roots lie, respectively, on first and second circumferences relative to the center, the second circumference, when the plastics film is in unstretched form and prior to placement about a container, being equal to or greater than a beading circumference of the container;wherein each tab of the four tabs is curved such that each tab has a curved edge facing the center, each curved edge forming an arc of a circle, the circle having a radius that is greater than a distance between the curved edge and the center of each quadra-arcuate aperture of the plurality of quadra-arcuate apertures;wherein a configuration of each quadra-arcuate aperture of the plurality of quadra-arcuate apertures is such that, upon placement of each quadra-arcuate aperture about a container of the plurality of containers, each peak of each tab engages with said beading of the container, wherein the plastics film, at a point where the peaks of the tabs meet with an underside of the beading of the container of the plurality of containers, is deflected in a downwards direction to form a non-planar wave effect in at least the first direction of the plastics film as the thin plastics sheet material elastically forms a three dimensional structure to retain the plurality of containers together; andwherein the plastics film can be provided as a roll. 2. The plastics film according to claim 1, wherein each tab extends inwardly towards the center. 3. The plastics film according to claim 1, wherein the troughs comprise rectilinear corner sections. 4. The plastics film according to claim 1, wherein the plastics film is made from a material comprising at least one of polyethylene, polyethylene derivatives and plastics materials with similar mechanical properties. 5. The plastics film according to claim 1, wherein the plastics film is made from recycled plastics. 6. The plastics film according to claim 5, wherein the plastics film is made from post consumer waste (PCW) plastics. 7. The plastics film according to claim 1, wherein the plastics film is made from 100-350 μm thickness plastics sheet. 8. The plastics film according to claim 1, further comprising further apertures within the thin plastics sheet material between the plurality of quadra-arcuate apertures for holding containers, such further apertures enabling stress relief, whereby each quadra-arcuate aperture of the plurality of quadra-arcuate apertures may more simply be fastened about a container. 9. The plastics film according to claim 1, wherein each quadra-arcuate aperture of the plurality of quadra-arcuate apertures is dimensioned to fit around cylindrical walled cans. 10. The plastics film according to claim 1, wherein each quadra-arcuate aperture of the plurality of quadra-arcuate apertures is dimensioned to fit about reduced chime or necked cans. 11. The plastics film according to claim 1, wherein each quadra-arcuate aperture of the plurality of quadra-arcuate apertures is dimensioned to fit around a neck of a bottle. 12. The plastics film according to claim 1, wherein the plurality of quadra-arcuate apertures are arranged in a single row. 13. The plastics film according to claim 1, wherein the plurality of quadra-arcuate apertures are arranged in more than one row. 14. The plastics film according to claim 1, wherein the beading of the container is a chime of a beverage container. 15. The plastics film according to claim 1, wherein the plurality of quadra-arcuate apertures can be placed over the beading circumference by deflecting the tabs and without stretching the plurality of quadra-arcuate apertures. 16. A method of unitizing containers utilizing the plastics film of claim 1, the method comprising: receiving a container of the plurality of containers;urging the curved edge of a tab of one quadra-arcuate aperture of the plurality of quadra arcuate apertures toward an under-chime edge of the container;easing adjacent side tabs of the one quadra-arcuate aperture over a corresponding rim of the container until the curved edge of the one quadra-arcuate aperture opposite a first engaged side of the one quadra-arcuate aperture is adjacent the corresponding rim of the container; andcausing the curved edge of a last tab to engage with an underside of the rim of the container, whereby to secure the plastics film with the container.
