I have found a large amount of developed (110 film) pocket film negatives. They are already cut in stripes of 3-5 negatives on one stripe. So the overall dimensions of the stripes range from about 70x16mm to 140x16mm.
How could I archive them in a way that they I get them into transparent A4 sheets that I can file them away in a binder and also can make contact prints (taking a foto of the sheet on light table) of off them.
Unfortunately these kind of transparent sheets do not seem to exist for pocket film only for 35mm. But using the 35mm ones for short and thin pocket film stripes would be a huge wast of space.
Given 110 has been an obsolete format for roundly twenty years, your best bet is probably to develop a technique of heat sealing the center of each 35mm sleeve on regular 35mm negative pages -- the ones for 6 strips of 6 negatives would hold 12 strips of your 110 (or Minolta, Edixa, or Rollei 16) negatives.
One of those vacuum food sealing machines can seal a straight line and do the whole length of each pocket in a single operation -- so around 15-30 seconds per page to make the alteration.
I'd not even worry about sealing the Printfile Pages. I have the 6 Frames x 6 Strips 35mm pages that Donald mentions and two strips per line fit easily enough and, whilst a tad fiddly, will stay put once placed.
Forgive the quick mobile phone snap:
