Using HDPE liquid fillers for packaging corrosive products

Corrosive or acidic liquids can potentially cause serious damage to packaging machinery if the systems aren’t designed to handle these products. However, production lines can avoid these issues through the use of specialized liquid filling machines for acids and other corrosives, preventing breakdowns.

While many packaging systems rely on stainless steel liquid packaging machines, acids and corrosives will easily eat away at this material over time, causing systems to shut down and resulting in costly downtime. Liquid fillers that handle corrosives and acids are normally made with high-density polyethylene, or HDPE, and use volumetric filling methods for consistent accuracy. These HDPE systems can prevent machine damage and subsequent breakdowns, helping maintain the efficiency of production while saving money.

HDPE machines can work with a range of corrosive and acidic liquids, including certain foods and beverages, oils, cosmetics, cleaning fluids, bleaches, and other acids or harsh chemicals. You can customize HDPE filler setups based on the size of the application and the physical space requirements in the facility.

HDPE liquid fillers function the same way as other filling machines, including the same features such as digital interfaces and high-speed filling capabilities. The only core difference between HDPE and stainless steel liquid fillers is the base construction materials. Packaging systems that use this machinery won’t experience any hindrance in the efficiency of the packaging process.

Supplementing with other HDPE packaging equipment

Typically, the liquid filler is the only machine to come into direct contact with the product, while the rest of the packaging line handles the packaged product. However, certain packaging operations may require the use of other equipment made of HDPE, including conveyors that carry the package along, helping avoid damage in the event of spills, drips or tips.

To determine the type of HDPE liquid packaging system your business needs, consult with a packaging expert who can recommend the type of system you need to keep your packaging system functioning optimally. With the implementation of a complete HDPE liquid filling system, businesses can more effectively maintain their production lines and maximize profitability.
