When it comes to the topic of the service life of PP bento boxes, the first thing we need to clarify is that for children, choosing a healthy bento box made of PP material is a safe and worry free choice. Its chemical stability ensures that it is harmless to human health under long-term use. However, any material item has its natural wear and tear cycle, and PP bento boxes are no exception.
High quality PP plastic lunch boxes, with proper maintenance, theoretically have a lifespan of up to 2 to 3 years. However, it is worth noting that over time, plastic materials will gradually age, affecting their durability and potential food safety performance. Therefore, in order to maximize health and safety, even these seemingly intact bento boxes are recommended to be updated and replaced once a year. Although this approach may seem redundant, it is actually a manifestation of responsibility for the health of family members.
In addition, consumers should also be aware that although some bento boxes on the market are made of high-quality PP material for the box body, the matching lid may use different materials with slightly lower quality. In this situation, if it is necessary to heat the bento, it is particularly recommended to remove the lid separately and then heat it to avoid the release of harmful substances that may be contained in the lid due to high temperature, which may contaminate the food and affect health. Although this detail may be small, it is related to health issues and cannot be ignored.
