We investigate the role of R-parity violating interaction in the non-leptonic
decays of B mesons into two light mesons B --> PP. The decay amplitudes are
calculated using the QCD improved factorization method. Using the combined data
on B decays from BaBar, Belle and CLEO, we obtain strong constraints on the
various products of R-parity violating couplings. Many of these new constraints
are stronger than the existing bounds.Comment: 19 pages including two eps figure
