The specific application method of leather splicing tape in leather production: Use to Splice release paper, Use to splice casting paper. Release paper and Casting paper are used in the making of synthetic leather creating a full range of excellent embossing patterns. There are 2 tapes used for splicing Casting paper. Lower Tape Used for Back Splice, Upper Tape Used for Top Splice.

Application method of leather splicing tape in leather production
Upper Leather Splicing Tape

Upper tape use for top splice No.A101

  • This leather splicing tape based on a PET film coating with high temperature silicone adhesive. The adhesive is clear or red color and have good adhesion on a release surface.
  • Release paper splicing tapes available for the top splice have a special release coat on the tapes surface which ensures easy removal of the synthetic leather from the splice.
  • Leather Splicing Tape withstand the temperature conditions encountered in the production of synthetic leather and will last through six or seven production cycles.
  • What this means is that the tape can go through the production process 6-7 times, so when the casting paper is reused, the tape can also be reused too.
