Paper perforated tape
Perforated paper tapes were one of the first media
storing low quantities of digital information. These tapes were used
widely to import and export data to/from early computer, to store
teletype messages or to store EPROM programmer source. There were many
types of these tapes, as they could store 4, 5, 6 or 7 holes in a row.
8-channel tapes were rare. The most popular tapes were used in teletype
units, they were 5 channel tapes with one tracking row. In computers 7
and 8-channel tapes were used, but not always - many early computers
used the same teletype tape and code, so results could be printed on an
ordinary teletype or fed to computer from teletype using tape.
Paper tapes were read mechanically and later optically. They were slower than magnetic tapes and could store less data.

This tape was used probably with MERA computer, as they frequently used 7-channel tapes. It's an 7-channel punched paper tape with one lead channel.
I have tried to decipher the data, they seem to be some numbers delimited by 0x1C.
Here are some photos from catalogues and magazines:

In 1960s and 1970s in Poland, perforated tape was a symbol of computer usage and automatization - it was present as a symbol of development of computer systems. We can see it on many propaganda materials, newspapers and logos. For example, we can see it on "30 years of People Republic of Poland" emblem printed even in notebook covers in 1970s:
