English Provender, which produces half a million products a week at its 90,000sq ft factory in Newbury, Berks, has redesigned its iconic square glass jars to achieve a reduction in materials.

The new 169g jars, used to pack sauces, condiments and chutneys, weigh 12g less than the old format and use 7% less glass.

Says Brand Manager Rachel Chang: “Last year, 2.2 million jars passed along our production lines, so this amounts to a substantial saving of materials. Environmental issues are increasingly important for both our trade customers and our consumers and we are pleased to be working towards a greener environment with this glass reduction.”

The lighter weight jars will also sport a subtle new look. Instead of the initials EPC stamped on the sides, the name English Provender is written out in full, giving customers better brand recognition.
