Our Best-Selling Glass Jars:
206 ml Lightweight Panel Jar
Light, strong and perfect for retail. Our 206 ml lightweight panel jar is a favourite among producers looking to reduce their carbon footprint without compromising on presentation. Its panel design makes labelling easy and elegant, while the lightweight construction keeps transport costs down, making it ideal for growing, sustainability-focused brands.
300 ml Panel Jar
Slightly larger but equally versatile, the 300 ml panel jar is a go-to choice for many high-volume producers. It offers a generous fill capacity while retaining the clean, professional look required for shelf impact. As an Essex-based glass manufacturer, we ensure every jar meets stringent quality standards to keep your product safe and looking great.
390 ml Reserve Jar
Designed with premium food products in mind, the 390 ml reserve jar is popular with producers of preserves, sauces and pickled goods. Its rounded shoulders and sturdy build make it an excellent choice for brands wanting to create a sense of luxury or heritage. If you’re a UK producer seeking a standout glass jar, this is one to consider.
540 ml Prosty Jar
Ideal for larger volumes, the 540 ml prosty jar is often used by high-volume producers and bulk packaging specialists. It’s practical, durable and capable of holding a wide variety of food types, from olives and pickles to cooking sauces and ferments. This is a hard-working jar that blends form and function with ease.
