CLAIMS
1. A film comprising a layer formed from a resin composition containing a polyamide compound (A) and a resin (B), wherein the polyamide compound (A) comprises: from 25 to 50% by mol of a diamine unit, which contains at least one diamine unit selected from the group consisting of an aromatic diamine unit represented by the following general formula (I-1), an alicyclic diamine unit represented by the following general formula (I-2) and a linear aliphatic diamine unit represented by the following general formula (I-3), in an amount in total of 50% by mol or more; from 25 to 50% by mol of a dicarboxylic acid unit, which contains a linear aliphatic dicarboxylic acid unit represented by the following general formula (II-1) and/or an aromatic dicarboxylic acid unit represented by the following general formula (II-2), in an amount in total of 50% by mol or more; and from 0.1 to 50% by mol of a constitutional unit represented by the following general formula (III): wherein, in the general formula (I-3), m represents an integer of from 2 to 18; in the general formula (II-1), n represents an integer of from 2 to 18; in the general formula (II-2), Ar represents an arylene group; and in the general formula (III), R represents a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group.
2. The film according to claim 1, wherein R in the general formula (III) represents a substituted or unsubstituted alkyl group having from 1 to 6 carbon atoms or
substituted or unsubstituted aryl group having from 6 to 10 carbon atoms.
3. The film according to claim 1 or 2, wherein the diamine unit contains a
xylylenediamine unit in an amount of 50% by mol or more.
4. The film according to any one of claims 1 to 3, wherein the linear aliphatic dicarboxylic acid unit contains at least one selected from the group consisting of an adipic acid unit, a sebacic acid unit and a 1,12-dodecanedicarboxylic acid unit, in an amount in total of 50% by mol or more.
5. The film according to any one of claims 1 to 4, wherein the aromatic dicarboxylic acid unit contains at least one selected from the group consisting of an isophthalic acid unit, a terephthalic acid unit and a 2,6naphthalenedicarboxylic acid unit, in an amount in total of 50% by mol or more.
6. The film according to any one of claims 1 to 5, wherein the polyamide compound (A) further comprises an .omega.-aminocarboxylic acid unit represented by the following general formula (X) in an amount of from 0.1 to 49.9% by mol based on the total constitutional units of the polyamide compound (A): wherein, in the general formula (X), p represents an integer of from 2 to 18.
7. The film according to claim 6, wherein the .omega.-aminocarboxylic acid unit contains a 6-aminohexanoic acid unit and/or a 12-aminododecanoic acid unit in an amount in total of 50% by mol or more.
8. The film according to any one of claims 1 to 7, wherein the resin composition contains, as the resin (B), at least one kind selected from the group consisting of a polyolefin, a polyester, a polyamide, an ethylene-vinyl alcohol copolymer, and a plantderived resin.
9. The film according to any one of claims 1 to 8, wherein the polyamide compound (A) has a relative viscosity of 1.8 or more and 4.2 or less, and a mass ratio of the polyamide compound (A)/the resin (B) is from 5/95 to 95/5.
10. The film according to any one of claims 1 to 8, wherein the polyamide compound (A) has a relative viscosity of 1.01 or more and less than 1.8, and a mass ratio of the polyamide compound (A)/the resin (B) is from 5/95 to 50/50.
11. The film according to any one of claims 1 to 10, wherein the film is biaxially stretched from 1.1 to 15 times in MD and from 1.1 to 15 times in TD.
12. A film packaging container comprising the film according to any one of claims 1 to 11.
