Types of Containers Used with Liquid Filling Machines

Gravity Filler liquid filling machine for low volume production

If your company sells products that are liquid and filled into containers before shipping off to their end destination, you probably know a thing or two about packaging machinery, and more particularly, liquid filling machines. There are a handful of different liquid filling machines, each designed to be most effective and efficient at filling certain types of liquids into bottles. Some machines are better for thin liquids, while others are best for thicker liquids, and if your product needs to be melted in order to pour it into a container, you’ll need a molten liquid system . Aside from the different machinery, though, there are also a variety of different containers that can be used with these machines. Learn more about some of the more common varieties of containers that are used with liquid filling machinery.

Paint – Plastic and Metal Cans, Small Glass Jars

Paint cans are traditionally metal with lids that are pressed into place, to be later pried open. This method keeps the paint securely contained within the pail, preventing it from drying out or getting contaminated with particles or debris in the air. Smaller containers of paint, typically marketed either for sample-sized amounts, or for hobbies, may be packaged in containers like small plastic tubs or small glass jars. In these two instances, spindle cappers are used to seal the paint.

Acids and Corrosives – Specific Materials for Corrosives

Acids and corrosive materials will generally need to be packaged in containers that are formulated to stand up to the contents. Depending on what the material is, simply lining the container with a shield may prove satisfactory. Other corrosive materials may only be reactive with metal or plastic, and therefore can be packaged into the material it won’t be corrosive to. If you need a custom container for your product, you should have no problem finding a supplier.

Beverages and Other Consumables – Plastic, Glass, Metals

Drinks and other food products can be filled in a number of different materials. Plastic is one of the most common, as plenty of drinks are packaged into plastic bottles and then topped off with a spindle cap. Other foods can be packaged into glass bottles or jars, and even metal bottles. Depending on the type of package and drink, these containers can be sealed using a press on lid, a twist on lid, or even a plug.

Pharmaceuticals – Plastics, Glass


Pharmaceuticals like pills or liquid medications, shampoos, and more can all be taken care of with either a pressure filler or a net weight filler. These filling machines keep the fill level consistent which ensures a quality product. This also ensures that people are given an appropriate amount of product that will correspond to the relevant dosages.

Molten Products (Candles, Lip Balms, Etc.) – Glass and Plastic

Molten products, like other liquid products, can be filled into a range of different containers. For instance, things like lip balm are often filled into plastic tubes or pots. Candles can also be filled into a variety of different containers, though they are most frequently packaged in glass.
