This variation on the 130 year old Philadelphia cheese brand was developed in Japan. Morinaga has worked to produce a cream cheese which creamy, yet melts at a higher temperature making it viable as a sliced cheese variety. Their solution was to create 3-layer cheese slices where Philadelphia cream cheese is sandwiched between cheddar cheese slices (the same as regular Kraft slices). The resulting combination is twice as thick as regular slices. At 4 combined slices per pack, that roughly equals in thickness (and I assume weight) the standard 8 regular slice packs.
This is being described as luxurious alternative to standard sliced cheese and Japan's first three layer cheese slices.
