Provided is a polyolefin resin packaging material having excellent clarity, heat resistance, bleed resistance and low-odor properties. The polyolefin resin packaging material is obtained by molding a polyolefin-based resin composition that comprises, with respect to 100 parts by mass of a polyolefin-based resin:
0.01 to 0.5 parts by mass of a benzylidene sorbitol compound represented by the following Formula (1):;(wherein, R represents a hydrogen atom or the like; and R1, R2, R3 and R4 each independently represent a hydrogen atom or the like); and0.01 to 0.5 parts by mass of a metal phosphate represented by the following Formula (2):;(wherein, R5 and R8 each independently represent an alkyl group having 1 to 8 carbon atoms or the like; R6 and R7 each independently represent a hydrogen atom or the like; R9 represents a direct bond or the like; R10 and R11 each independently represent a hydrogen atom or the like; M represents an alkali metal or the like; n represents an integer of 1 to 3; and m represents an integer of 0 to 2). |

1. A polyolefin resin packaging material obtained by molding a polyolefin-based resin composition,
said polyolefin-based resin composition comprising, with respect to 100 parts by mass of a polyolefin-based resin: 0.01 to 0.5 parts by mass of a benzylidene sorbitol compound represented by the following Formula (1): (wherein, R represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; and R1, R2, R3 and R4 each independently represent a hydrogen atom, a halogen atom, a cyano group or an alkyl group having 1 to 4 carbon atoms); and 0.01 to 0.5 parts by mass of a metal phosphate represented by the following Formula (2): (wherein, R5 and R8 each independently represent an alkyl group having 1 to 8 carbon atoms, or a cycloalkyl, aryl, alkylaryl or arylalkyl group having 6 to 12 carbon atoms; R6 and R7 each independently represent a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, or a cycloalkyl, aryl, alkylaryl or arylalkyl group having 6 to 12 carbon atoms; R9 represents a direct bond or an alkylidene group having 1 to 4 carbon atoms; R10 and R11 each independently represent a hydrogen atom or a methyl group; M represents an atom of an alkali metal, an alkaline earth metal, zinc or aluminum; n represents an integer of 1 to 3; m represents an integer of 0 to 2; when M is an alkali metal, n is 1 and m is 0; when M is an alkaline earth metal or zinc, X is a hydroxy group and m is 1 if n is 1, and m is 0 if n is 2; and when M is aluminum, m is 2 if n is 1, m is 1 if n is 2, with X being a hydroxy group in both of these cases, and m is 0 if n is 3). |
