Why HDPE Sheets Can Improve The Safety Of Food Packaging

When manufacturing food packaging, there are many things that manufacturers must consider. These requirements are further heightened when manufacturing food and food-related products. Because food must remain fit for consumption, manufacturers must create packaging that minimizes the risks of contamination while still providing safe food access for consumers. Traditionally, materials such as metal have been used to manufacture food packaging. However, there are several disadvantages associated with metal food packing. Fortunately, high-density polyurethane sheeting has emerged as an option that manufacturers can use to improve the safety of food packaging and reduce the risk of contamination. These flat plastic sheets are made of specialized materials that ensure that they integrate well in food-related use cases. Read on below to learn why HDPE sheets can improve the safety of food packaging.

HDPE Sheet Plastic Doesn't Cross-Contaminate With Food

Many food packaging materials have issues with cross-contamination. These foods will leach into the food that they contain, or the food's fluids may be absorbed by the packaging material. The leaching issue is particularly prevalent when dealing with metal packaging. Metals such as steel, aluminum, and nickel are frequently used in food packaging. Unfortunately, these metals leach into the packaged food over time. If acidic foods are contained within these forms of packaging, the leaching rate will be higher. These metals can be toxic to humans and, in extreme cases, can cause adverse reactions such as dermatitis. HDPE is a food-grade material that doesn't leach into food nor absorb any of the fluids that may be held within the packaging. This trait makes HDPE packaging ideal for beverages, soups, and more.

Another advantage of HDPE packaging is that it is corrosion-resistant. Wood can suffer from rotting when exposed to moisture. On the other hand, metal corrodes when exposed to moisture. A common form of corrosion that afflicts metal is rust. Rust can cause metal flakes to break off into the food, further increasing the food contamination levels. Rust can also react with food, causing it to spoil faster than it otherwise would.

HDPE Sheet Plastic Is Durable

High-density polyurethane lives up to its name in that it is a durable material. The material's impact resistance reduces the likelihood of spillage and breakage during the manufacturing process as well as when the product is in the hands of consumers. This quality enhances the overall safety and usability of packaging that uses HDPE technology.


Traditional materials such as stainless steel and aluminum have numerous harmful effects on packaged food. Fortunately, HDPE sheets offer food manufacturers a safe, durable, and effective food packaging option.
