Are IBC Totes BPA-Free?

Intermediate Bulk Containers (IBCs) are a versatile solution for transporting and storing a wide range of liquids and bulk materials. But a common question arises, especially when dealing with food-grade products: are IBC totes BPA-free? The short answer is yes, Wenplastics’ new and rebottled IBC totes are BPA-free. This is because are constructed from high-density polyethylene (HDPE), a thermoplastic polymer that does not contain Bisphenol A (BPA).

What is BPA and Why is it a Concern?

BPA is an industrial chemical that has been used since the 1950s to make certain plastics and resins. It’s commonly found in polycarbonate plastics, which are often used for food and beverage containers. The concern with BPA is that it can leach from these containers into the food and beverages they hold. Some studies have suggested a possible link between BPA exposure and a variety of health problems. While the U.S. Food and Drug Administration (FDA) has stated that BPA is safe at the very low levels that occur in some foods, many consumers and manufacturers are opting for BPA-free products as a precautionary measure.

IBC Totes and Materials

IBC totes come in a few different varieties, with the most common being:

– Plastic IBCs: The most common type of IBC, these are made from high-density polyethylene (HDPE). This material is known for its durability, impact resistance, and is naturally BPA-free. Wenplastics manufactures these high-quality totes to meet the demands of various industries.

– Caged IBC Totes: A popular choice, these consist of an HDPE plastic container housed within a protective steel cage. This design provides excellent stability and protection for the contents.

The Importance of UN Ratings for Food-Grade Products

When using IBC totes for food-grade products, it’s not enough to simply ensure they are BPA-free. They must also have the proper UN rating. The United Nations (UN) has established a set of standards for the transportation and storage of hazardous materials, and these ratings are also crucial for ensuring the safety and quality of food products. A UN rating on an IBC tote indicates that it has been tested and has passed specific safety and design standards. This is particularly important for food-grade applications to prevent contamination and ensure the integrity of the product. The UN marking will include codes that specify the type of container, the material it’s made from, and the packing group it’s suitable for. For example, a UN marking of “UN31HA1” indicates:

• UN: United Nations
• 31: Intended for liquid use
• HA: Composite construction (plastic and steel)
• 1: Features structural equipment for load support

When selecting an IBC tote for food-grade use, look for totes that are not only BPA-free but also have the appropriate UN rating for the specific product you will be storing or transporting. New and “rebottled” IBCs, which have a brand new inner container, are generally certified for food-grade and potable water applications. Reconditioned or refurbished totes, however, may have a previous usage history that makes them unsuitable for food products.
