- (3) a plastic wrap package;
- wherein the inner surface of the film is a matte or embossed surface with a surface roughness (Ra) of from 2 to 10 .mu.m and not greater than 1/2 the thickness of the film, and the static and kinetic friction coefficients of the release treated matte or embossed inner surface are less than 1.5 and 1.2, respectively.
- 3. A package, separator and sanitary napkin combination comprising in this order:
- (1) a sanitary napkin having on a surface thereof a pressure-sensitive adhesive layer for affixing the napkin to an undergarment,
- (2) a separator comprising a thermoplastic plastic film from 20 to 40 .mu.m in thickness having (a) an inner surface which is a matte or embossed surface with a surface roughness (Ra) of from 2 to 10 .mu.m and not greater than 1/2 the thickness of the film, coated on at least a part thereof with a release treatment layer selected from the group consisting of an ultraviolet setting silicone treatment layer and an electron ray setting silicone treatment layer, said release treatment layer being removably adhered to the pressure sensitive adhesive layer on the napkin, and (b) an outer surface,
- (3) a pressure-sensitive adhesive layer having an inner surface adhered to at least a part of the outer surface of the separator, and an outer surface, and
- (4) a plastic wrap package adhered to the outer surface of the pressure-sensitive adhesive layer and enclosing the napkin;
- wherein the static and kinetic friction coefficients of the release treated matte or embossed surface are less than 1.5 and 1.2, respectively.
- 4. The combination of claim 1, wherein the surface roughness (Ra) of the outer surface is 25 .mu.m or less.
- 5. The combination of claim 2, wherein the surface roughness (Ra) of the outer surface is 25 .mu.m or less.
- 6. The combination of claim 1, wherein the thermoplastic plastic film is a single layer polymer film composed of a polymer blend.
- 7. The combination of claim 2, wherein the thermoplastic plastic film is a single layer polymer film composed of a polymer blend.
- 8. The combination of claim 3, wherein the thermoplastic plastic film is a single layer polymer film composed of a polymer blend.
- 9. The combination of claim 6, wherein the polymer blend is a blend of at least two polymers selected from the group consisting of polyethylene, polypropylene, ethylene-vinyl acetate copolymers, ethylene-(meta)acrylic acid copolymers, ethylene-methyl (meta)acrylate copolymers, ethylene-ethyl (meta)acrylate copolymers, polyethylene-propylene copolymers, olefinic elastomers, styrenic elastomers, polyisobutylene, and butyl rubber.
- 10. The combination of claim 7, wherein the polymer blend is a blend of at least two polymers selected from the group consisting of polyethylene, polypropylene, ethylene-vinyl acetate copolymers, ethylene-(meta)acrylic acid copolymers, ethylene-methyl (meta)acrylate copolymers, ethylene-ethyl (meta)acrylate copolymers, polyethylene-propylene copolymers, olefinic elastomers, styrenic elastomers, polyisobutylene, and butyl rubber.
- 11. The combination of claim 8, wherein the polymer blend is a blend of at least two polymers selected from the group consisting of polyethylene, polypropylene, ethylene-vinyl acetate copolymers, ethylene-(meta)acrylic acid copolymers, ethylene-methyl (meta)acrylate copolymers, ethylene-ethyl (meta)acrylate copolymers, polyethylene-propylene copolymers, olefinic elastomers, styrenic elastomers, polyisobutylene, and butyl rubber.
