1. A stack of web material for hygiene products, comprising:
at least one web material being Z-folded about transverse folding lines, thereby providing panels having a length along said folding lines, and a width perpendicular to said folding lines,
said panels being piled on top of each other to form a height of said stack extending between a first end surface and a second end surface of the stack, and
said first end surface being provided with a first connector, and said second end surface being provided with a second connector, said first connector and said second connector being adapted for interconnection of the first end surface of the stack to a second end surface of another, similar stack, and/or for interconnection of the second end surface of the stack to a first end surface of another, similar stack, wherein
said first connector comprises a first smooth connection surface consisting of a first material,
said second connector comprises a second smooth connection surface consisting of a second material; and
said first material and said second material being polymer materials which have been sprayed or extruded onto the stack or which are provided in the form of a film provided on the stack and having properties so that, upon bringing said first connection surface and said second connection surface into contact with each other, the first connection surface and the second connection surface attach to each other by surface adhesion of a kind where the first connection surface and the second connection surface are repeatedly removable from and reattachable to each other while leaving the first connection surface and the second connection surface substantially unaltered,
whereby a connection between a first connector/second connector of the stack and a second connector/first connector of a similar stack is accomplished, said connection having a connection strength in a plane including the first connection surface and the second connection surface sufficient to pull the web material of the interconnected stacks,
wherein the stack is configured to be pulled through a dispenser.
