A good chutney jar must meet five technical requirements: a food packaging grade glass specification with a minimum thermal shock resistance of 60°C, validated to BS EN ISO 7459:2004; a hot-fill suitability rating for filling at 85°C or above; a twist-off neck finish in 58mm, 63mm, or 70mm diameter matched precisely to a plastisol-lined closure; a capacity specified by fill weight rather than volume, given that chutney has a specific gravity of 1.1 to 1.3; and a Declaration of Compliance from the supplier confirming food contact suitability under UK-retained Regulation 1935/2004.
