our expertise

Along with its brands Zeller Plastik, UCP, Astra Plastique and Massmould, GCS is a leading supplier of dispensing closures and lined and unlined screw closures for the food market.


GCS brands are well known for their expertise on integrated valve closures that offers controlled product dispensing for enhanced convenience, including the recent introduction of closures designed to dispense products with particulates and thicker products, such as honey, more easily. Our technical experts can recommend the right closure / valve combination for your product needs and we can also provide advice regarding bottle design to ensure the dispensing experience is optimised.


In addition GCS offers non-valve dispensing closures with flow restrictors – ideal for vinegar, dressings and edible oil – including one design which offers a variable flow using an innovative adjustable insert. Our portfolio is also composed of a vast range of snap-hinge screw-on and push-on closures, with many different neck finishes, orifice diameters and orifice shapes, suitable for various food applications, such as dressings, condiments, sauces, spreads and conserves.


GCS, along with its brand Massmould, is the European leader for Induction Heat Sealed Wide Mouth closures for dry beverage applications, such as granulated coffee, and other freeze dried products. Its extensive expertise in the coffee market has also enabled GCS to become one of the leading manufacturers of capsules for coffee and tea dispensing machines.
