Try using the term edgebanding for your search. You should find many online sources. Many different materials and adhesive options are available. Wood grain and white melamine iron on edgebanding are available at most Home Depot stores in the US. Typically it is wider than the stated size and must be trimmed down. You will get the best results using a router with a laminate trimming bit. If you don't have a router inexpensive edging tools are available but I have never liked them that much. Either way Practice on some scrap material first for best results.
