IBC Totes have become essential storage and transportation solutions across numerous industries, particularly when handling liquids and pourable materials. A common concern for those using these containers is whether they contain Bisphenol A (BPA), a chemical compound with potential health implications. This report explores the BPA status of IBC totes, their composition, and what this means for various applications.
Understanding IBC Totes and Their Composition
Intermediate Bulk Containers (IBCs) are versatile storage containers ranging in capacity from 275 to 330 gallons, designed for efficient transportation and storage of liquids and flowable materials. These cube-shaped containers typically consist of a plastic inner tank supported by a metal cage structure.
Most IBC totes feature tanks made from high-density polyethylene (HDPE), a thermoplastic polymer commonly used in producing plastic bottles and containers. This material choice is significant when discussing BPA content, as HDPE is naturally BPA-free by composition.
BPA-Free Status of IBC Totes
The evidence overwhelmingly confirms that standard IBC totes are indeed BPA-free. According to industry sources, “IBC totes are BPA free and to the best of our knowledge have always been”. This is primarily because the high-density polyethylene used in manufacturing these containers does not require BPA in its production process.
HDPE plastics are completely free from BPA and therefore safe for human-use applications. Like BPA, HDPE is a plastic made from petroleum; however, it is not manufactured with any of the same toxic chemicals found in BPA. This inherent characteristic makes HDPE an ideal material for containers that may come into contact with substances intended for human consumption.
Material Safety and Manufacturing Standards
The polyethylene resin used in IBC totes, along with additional constituents such as UV stabilizers, meets FDA and ANSI/NSF 61 requirements and is BPA-free for drinking water applications. This compliance is critical for industries that require stringent safety standards.
Rebottled poly totes, which feature a new tank fabricated from virgin HDPE within a refurbished steel cage, maintain this BPA-free status. The manufacturing process ensures that the high-density polyethylene is robust, resistant, and rated for liquids up to 1.9 specific gravity while remaining free of potentially harmful chemicals.
Why BPA-Free Matters: Health and Safety Implications
The importance of BPA-free containers becomes evident when examining the potential health risks associated with BPA exposure. Research has linked BPA to numerous health concerns, including:
- Lipid metabolism issues leading to obesity
- Aneuploidy potentially causing Down’s syndrome and other birth defects
- Increased risk of certain cancers, including breast and prostate cancer
- Elevated rates of liver toxicity, diabetes, and heart disease
- Hormone disruption and fertility issues
BPA can enter the human body through hydrolysis, leaching out of materials into food or liquids, and in some cases, may even be absorbed through skin contact. By using BPA-free IBC totes, these health risks are significantly mitigated.
Food-Grade Applications and FDA Compliance
For food and beverage applications, IBC totes are available in FDA-compliant versions. These food-grade totes are specifically designed for storing and transporting edible goods throughout the supply chain. Food-grade IBC totes are made from approved materials like virgin HDPE, stainless steel, and food-grade resins to prevent leaching and flavor transfer.
Many IBC totes are FDA compliant and BPA-free for a wide range of food products. A food-grade IBC will typically be made of virgin HDPE or corrugate. These containers meet stringent standards set by regulatory bodies like the FDA in the United States and the Food Safety System Certification (FSSC) 22000 standards in the EU.
Identifying BPA-Free IBC Totes
To identify BPA-free IBC totes, consider these guidelines:
Material Verification: Most IBC totes made from HDPE (plastic recycling code 2) are inherently BPA-free.
Labeling: Food-grade totes will have a label that clearly states they are intended for food use.
Manufacturer Certification: Reputable manufacturers will specify that their products are BPA-free and FDA-approved for food contact.
UN/DOT Markings: The best way to identify food-grade HDPE totes is through permanent UN/DOT markings molded into the sidewall.
- Specialized BPA-Free Options for Specific Applications
For specialized applications requiring additional assurance of food safety, there are also form-fitting IBC tote liners available. These FDA-compliant liners are designed without folds that could trap contents during discharge or air pockets that might prevent complete filling. The liner material meets FDA requirements for contact with food products, providing an additional layer of protection.
Some manufacturers offer 330-gallon IBC totes made from heavy-duty high-density polyethylene that is specifically advertised as free of both BPA and DEHP byproducts. These materials are designed to be safe for people, animals, and the natural environment.
