appreciated that they can be any shape which will fulfill the need of the products to be packaged such as oval diamond etc similarly the transverse linking members need not be of any particular configuration in cross section the material of the packaging product may be flexible rigid or semi rigid depending upon the particular application and as described hereinbefore and the longitudinal strands and linking members may be of different materials if desired as for example when the material is made according to u s pat no 3 700 521 where the material is made of flexible thermoplastic it will be appreciated that it can be bent to conform to any particular shape desired it will further be appreciated than in certain applications it would be of advantage to make the material of rigid thermoplastic especially from a tube as shown in fig1 so that packaging product of arcuate cross section is obtained the transverse members are preferably but need not necessarily be of smaller cross section than the longitudinal members the relative cross sections varying in accordance with intended end use the packaging product need not be entirely of the same material and materials such as polyethylene polyamide polypropylene and elastomeric foamed and expanded materials may be used for individual members the material of which the packaging product is made need not be extruded also all the longitudinal members or all the transverse members or both need not be of uniform size for example the size of the longitudinal or the transverse members or both may alternate between two sizes for adjacent members the smaller members may be flexed aside during use and act as additional separating material between rows or layers supplementary members may also be added for example.
