Abstract
Membranes such as fluorine-containing cation exchange membranes are wrapped on a roll for shipment, without using adhesive to fasten the membrane to the core or to itself at the end of the wrap. Instead, paper is taped to the core and interleaved with the membrane. At the end of the wrap, paper is again interleaved with the membrane and the paper is taped to itself.
Claims11
A package for membrane comprising a core and a means for securing at least one sheet of membrane on the core such that the membrane is free from contact with any kind of adhesive, wherein a first sheet of membrane is secured to said core by adhering a first edge of a sheet of paper of substantially the same width as said membrane to the core and wrapped on said core, and a first edge of said first sheet of membrane is interleaved with a second edge of the paper for an effective overlap distance at a tension sufficient to hold the membrane in place, a first edge of additional subsequent sheets of membrane through and including the final sheet of membrane are each interleaved with a second edge of the preceding membrane at a tension sufficient to hold each sheet of membrane in place, the second edge in each case being parallel to and opposite the first edge.
