ABSTRACT A method of making reclosable film plastic bags which comprises forming a plastic film strip with a first longitudinal separable fastener profile on one face, forming a complementary second longitudinal profile on the face of the strip sufficiently spaced from the first profile to provide a bag body when the strip is folded longitudinally to join the profiles. Substantially spaced from the first and second profiles, a pair of third and fourth profiles are adjacently spaced from one another. The strip is folded longitudinally and the first and second and third and fourth profiles are joined in separable fastener relation. Thereby, the folded strip provides re- latively narrow areas between the joined first and second profiles and the joined third and fourth profiles, and pro- vides a substantially longer bag body extending from the joined first and second profiles in the opposite direction relative to the relatively narrow areas. The plastic film strip may originally comprise a tubular extrusion, or it may comprise a flat strip.
