Claims24
A package comprising a packaging element made of a support material comprising a coating layer containing a moisture regulating composition, the moisture regulating composition comprising:
- 20-60 weight percent on total dry weight basis of at least one Metal-organic framework compound and 80-40 weight percent on total dry weight basis of at least one binder material, wherein the at least one Metal-organic framework compound is chosen in a group comprising:
- Aluminium Fumarate (C12H6Al2O12),
- chromium terephthalate Metal-organic frameworks MIL-101 (Cr), comprising trimeric chromium (III) octahedral clusters interconnected by 1,4-benzenedicarboxylates and having empirical formula [Cr3(O)X(bdc)3(H2O)2], wherein bdc is benzene-1,4-dicarboxylate and X is OH or F,
- functionalized chromium terephthalate Metal-organic frameworks MIL-101(Cr)-X, where X denotes an electron withdrawing group selected from NO2, SO3H and Cl, or an electron donor group selected from NH2 and CH3,
- iron terephthalate Metal-organic frameworks MIL-101(Fe),
- chromium-based Metal-organic frameworks with underlying soc topology Cr-soc-Metal-organic framework-1 with chemical formula [Cr3(μ3-O)(H2O)2(TCPT)1.5Cl] where TCPT is tetratopic 3,3″,5,5″-tetrakis(4-carboxyphenyl)-p-terphenyl ligand,
- isostructural Zr(IV)-MOFs with rare low-symmetric 9-connected Zr6 MOFs, indicated as Zr(IV)-MOFs BUT-46F, BUT-46A, BUT-46W, and BUT-46B,
- hybrid microporous highly connected rare-earth-based Metal-organic frameworks Y-shp-MOF-5, where “shp” denotes square hexagonal prism,
- or any combination thereof,
- wherein the at least one binder is chosen in a group comprising:
- starch ((C6H10O5)n-(H2O)), alginic acids ((C6H8O6)n), alginates, copolymers of polyacrylic acid ((C3H4O2)n), and/or copolymers of maleic acid (HO2CCH═CHCO2H), polyaspartic acid ((C4H5NO3)n), polyvinylalcohol-co-ethylene (EVOH, C4H8O), polyvinylalcohol-co-vinyl acetate, polyethylene oxide ((—CH2CH2O—)n), or any combination thereof;
- wherein the coating layer containing the moisture regulating composition has a thickness comprised between 10 micrometres and 80 micrometres.
