The invention relates to a packer (7) to be included in a production tubing (4) in a well bore (1). The packer (7) comprises an expandable bag (11) located on the outside (56) of a packer body (9), the bag (11) having an outwardly facing semi-permeable wall (12) made from fabric. When setting the packer, a liquid curable resin is injected into the bag (11), which causes an expansion of the bag (11). The resin partly penetrates the outwardly facing fabric wall (12) and seals against the well bore wall (10), and after curing forms a packer seal (58). The invention also relates to a setting tool for setting the packer (7) in the well bore (1) and a method for setting a packer (7) in a well bore (1).
