Liquid Filling Machines and the Industries That Use Them

Posted by

Liquid Filling Machines

Liquid filling machinery fulfills many businesses’ needs for fast, efficient packaging. There are a handful of different machines that are most commonly used, and because all of these machines are so versatile, many different industries use them. Today, you’ll learn more about some of the machinery that’s out there—not just the actual liquid filling machines, but affiliated machinery, as well—and which different industries use them.

Bottle Cleaners

Bottle cleaners are typically the first in the line – they clean out the containers that will soon be filled with product. They effectively remove particles and dust from glass, metal, and plastic bottles, particles that often accumulate during shipping or storage. A common bottle cleaner is an air rinser , which fill containers with air and then vacuum the air back up, leaving behind a clean, ready-to-fill bottle.

Capping Machines

Capping machines are an essential part of the packaging process, as they add caps, plugs, or lids to containers in a quick and accurate process. There are a few different types—chuck cappers, wheel pluggers, snap cappers, and spindle cappers are four of the most common—and each is best suited to a different type of bottle. Other equipment that works well with capping machines are accessory machines like cap sorters and cap elevators.


Conveyers are another key component to many packaging lines, as they carry products from one station to the next. For instance, a product may need to be cleaned first so it will travel on the conveyer belt from a bottle cleaner to a liquid filling machine before heading to a capping machine and a labeler. Conveyers help maintain consistent speed throughout the packaging process. There are also machines like cooling conveyers, which are ideal for molten products like candles. These conveyers promote even cooling and an even fill line.

Labeling Machines

Labeling machines do exactly what they suggest—affix labels to containers. Hazardous location labeling machines are also available for products that require pressure sensitive labels.

Liquid Filling and Molten Filling Machines

Liquid filling machines fulfill many needs, including molten products like candles and lip balms. There are a variety of liquid filling machines that are ideal for different types of liquids. Some of those machines include:

  • Gravity fillers
  • Net weight fillers
  • Overflow fillers
  • Piston fillers
  • Portable molten fillers
  • Molten filling machines
  • Pressure fillers
  • Pump fillers

Which Industries Use This Equipment?

Because so many different industries sell products that are packaged liquids, it stands to reason that those same industries use these types of machines. For instance, the distilled spirits, food, and beverage industries all use liquid filling equipment for things like wine, spirits, salad dressings, and soft drinks. The cleaning industry uses this equipment for things like floor cleaning solution, multipurpose cleansers, and laundry detergent. Other industries that use liquid filling machinery include:

    Acids & Corrosives

    Made from HDPE (high density polyethylene), our acids and corrosives filling machines, conveyors and turntables are designed to handle the punishment of a highly corrosive environment where standard metal components would normally dissolve.

    Juice & Other Beverage

    Here at E-PAK, we designs and assembles highly sanitary and corrosion resistant bottle filling systems for juice and other beverages. We know that when working with beverages bottling equipment must be created for both safety and resistance to spoiling.

    Candles, Lip Balms & Molten

    E-PAK Machinery knows the specialized needs of companies filling molten products and can scale to grow depending on production needs. From table top molten fillers to fully automated end-to-end inline molten filling machinery, our experts manage every step of the design, manufacturing and installation process for products such as candles, cosmetics, lip balms, molded and glycerin soaps, deodorants, shoe polish, carnauba wax and much more.

    Personal Care, Health & Beauty

    E-PAK modifies filling equipment for products of all kinds, guaranteeing that your production line is well organized while challenging the chemical properties that can compromise its longevity. From high-viscosity cosmetics and lotions to corrosive polish removers and more, cosmetic products all have individual chemical properties. This means that filling machines for those items must be distinctly different, as well.

    Food Products & Sauces

    We understand that sanitation is paramount in the food service industry, as is durability when working with viscous liquids and sauces. Our filling machines are available in all sanitary designs featuring quick disconnect valves, sanitary tubing, pumps and tri-clamp fittings.

    Industrial & Agricultural Chemicals

    E-PAK configures different types of bottling machines for chemicals, and has experience with both industrial and agricultural compounds. Liquid filling equipment intended for agricultural or industrial chemicals should always be designed with the necessary corrosion resistance, as well as to accommodate varying viscosities and foaming properties.

    Janitorial & Cleaning Supplies

    Let our experienced sales and engineering teams work with you to develop a solution that will fit your cleaning and janitorial supply requirements. E-PAK organizes and installs filling systems for janitorial and cleaning supplies of all varieties, so no matter the viscosity, acidity or foaming properties, your production line can function competently and safely.

    We also specialize in custom filling machinery for paints, stains and sealants, petroleum, automotive products, pharmaceuticals, distilled spirit, wine and much more.
