Understanding Materials Approved for Food Contact
The term “food grade” isn’t just a label; it represents a commitment to safety and purity. It signifies that a material has been rigorously tested and approved to be in direct contact with food and beverages without leaching harmful substances or altering their taste or odor. This approval process often involves compliance with stringent standards set by regulatory bodies.
Several materials meet these demanding criteria, but two stand out as the most common choices for food grade water tanks: polyethylene and stainless steel.
Let’s begin with polyethylene (often referred to as PE or HDPE, high-density polyethylene). This material is a workhorse in the water storage industry, lauded for its combination of affordability, durability, and versatility. Food grade polyethylene tanks are lightweight, making them easier to transport and install. They’re also remarkably resistant to impacts and cracking, able to withstand the rigors of outdoor environments, especially when treated with ultraviolet stabilizers to combat sun damage. Moreover, polyethylene tanks are cost-effective, making them an attractive option for budget-conscious consumers and businesses. However, it’s important to note that polyethylene is not universally resistant to all chemicals and may not be suitable for storing water at extremely high temperatures. Certain grades of polyethylene are specifically certified as food grade, demonstrating their suitability for potable water and food-related applications.
Then we have stainless steel, the gold standard for food grade applications. Stainless steel tanks are renowned for their unparalleled durability, corrosion resistance, and hygienic properties. The smooth, non-porous surface of stainless steel prevents the growth of bacteria and algae, ensuring exceptional water quality. These tanks are also incredibly long-lasting, often outperforming polyethylene tanks in terms of lifespan. While stainless steel comes with a higher price tag and greater weight, its longevity, hygienic properties, and resistance to extreme temperatures and chemicals make it a worthwhile investment for many. Within the realm of stainless steel, certain grades, such as three hundred four and three hundred sixteen, are commonly used for food grade water tanks, each offering varying levels of corrosion resistance.
While less common, other materials such as specific types of fiberglass with a food grade lining may also be employed in the construction of these tanks, but their usage is less prevalent than polyethylene and stainless steel.
The significance of using food grade materials cannot be overstated. It’s about more than just meeting regulations; it’s about safeguarding human health and preserving the integrity of your water supply. Non-food-grade materials can leach harmful chemicals like BPA and phthalates into the water, posing potential health risks, especially with prolonged exposure. Furthermore, they can impart unpleasant tastes and odors, rendering the water unpalatable.
The Indisputable Benefits of Using Food Grade Water Tanks
Choosing a food grade water tank is not merely a matter of compliance; it’s a proactive investment in your health, safety, and the long-term viability of your water storage system.
The most compelling benefit is, without doubt, health and safety. Using a non-food-grade tank is akin to playing Russian roulette with your water supply. The potential for chemical contamination is real, and the consequences can be severe, ranging from mild gastrointestinal distress to more serious health problems. Food grade tanks eliminate this risk, providing peace of mind knowing that your water is free from harmful substances.
Beyond health, food grade tanks excel at preserving water quality. They prevent the leaching of materials that can alter the taste and odor of your water, ensuring that it remains fresh and palatable. This is particularly important for drinking water and for processes where water purity is critical, such as in food and beverage production.
