Bucket Material Safety Comparison: Health Risks Cannot Be Ignored


1. Safety Concerns Regarding PCs

The biggest concern regarding PC materials is the release of Bisphenol A (BPA). Studies have shown that BPA may leach from PC containers when exposed to high temperatures (above 70℃) or after prolonged use. Once BPA enters the human body, it may disrupt the endocrine system and affect reproductive development, posing a significant risk to infants and young children. Although some PC products now claim to be "BPA-free," there are still potential risks associated with storing water in them for extended periods, especially hot water or under direct sunlight.

2. Safety Advantages of PE

PE materials are relatively safe, non-toxic, and do not contain harmful chemicals. Even under normal use and storage conditions, they do not release toxic substances. However, low-quality PE products may contain recycled materials or harmful additives, so it is necessary to look for food-grade certifications when purchasing. For example, food-grade HDPE is often used to make drinking water containers due to its high stability and suitability for long-term contact with water.

Methods for Identifying PC Material in Pure Water Buckets

The identification of PC water buckets follows a series of standards explicitly defined by the quality inspection authorities. According to the instructions of the State Administration for Market Regulation, bottled water manufacturers must use PC buckets (polycarbonate buckets), while PET buckets (polyethylene terephthalate buckets) are strictly prohibited due to the potential release of toxic substances upon heating.
