Sort the food jars and bottles you like by size. Choose the size from the column on the left. Food jars are sold by the approximate weight of the product to be packaged. All fluid capacities in millilitres are stated for reference. TOP TIP: If you are unsure what size jar you need, weigh your desired quantity of product in a graduated measuring jug to get the fluid capacity that your jar needs to be. Please ensure all packaging components are tested with the intended product. Freeman and Harding Ltd accept no responsibility for any loss resulting from incompatibility. All jars and bottles have height, diameter and fluid capacity dimensions in the DATA tab. Most also have a technical drawing available for download.
