What is BIND plan in DB2?

If you specify one or more DBRMs to include in the plan (by using the MEMBER option of BIND PLAN), Db2 automatically binds those DBRMs into packages and then binds those packages into the plan.

What is the difference between BIND plan and bind package?

A DBRM can be directly bound to a plan or we can first bind DBRM into a package and then bind that package into PLAN. In case DBRM binds to a plan directly, if there is some change in the source code, the new DBRM has to be generated and then we have to bind the entire plan again.
