A variety of filling systems for dense products such as edible oils and sauces are available for filling various types of containers from glass bottles to PET and cans, ranging from the high vacuum filling system to positive pressure filling, volumetric piston filling, net weight filling and flowmeter system.

Such versatility enables us to supply filling lines capable of processing a vast range of different bottle designs commonly used for “boutique” olive oils, as well as the traditional packaging. GLOPAK can supply customers with a tailor made solution from small semiautomatic equipment to the high speed bottling and packaging lines.

Volumetric (or piston)

filling system guarantees that the container is filled with an exact quantity of product, having a maximum tolerance of +/- 1,5 cc using 1 litre cylinders. This result is obtained regardless of the product’s thickness and of the differences in actual capacity between containers of the same type and size. Therefore piston filling is the correct choice for applications where accuracy of actual volume contained in the bottles is important, or in case of filling dense products into plastic containers.

Net weight

filling system is used for various types of still products including thick and viscous liquids, such as vegetable oils, detergents, liquid soaps, etc into containers of any kind including soft plastic material such as PET or HDPE bottles.

The advantage of this system is that is very gentle on the product and allows extremely precise net weight measurement, regardless of the empty container weight variation.

Low vacuum-gravity

filling systems are recommended for still, non-dense products such as for example still water, wine, alcoholic beverages (vodka, whiskey, brandy, etc), chemical products and generically any kind of flat non viscous liquids.

Various models of filling valves are available within this category, specifically designed to cater for the filling level requirements, bottle shape, neck shape and product.

Several optional features are available such as the “millimetric adjustment of the filling level” controlled directly from the user interface panel, air return outside the filling tank (to avoid the air from the bottles contaminating the product in the filler bowl), centralized level regulation and more.

Positive Pressure

 filling system is used for thick and viscous liquids, such as vegetable oils, syrups, sauces, etc into containers of any kind including soft plastic material such as PET bottles.

As opposed to the gravity or low vacuum system, the filling takes place by creating a positive pressure inside the filler bowl, allowing the product to flow from the filling tank to the containers more easily.
