In today's increasingly environmentally conscious society, there is a growing global demand for reducing pollution. We need to understand why foam lunch boxes are banned.

As we all know, foam lunch boxes are mainly made of polystyrene and other plastic materials. foam lunch boxes are widely used in the catering industry because of their low cost, light weight, good thermal insulation and other advantages. Especially in developing countries, foam lunch boxes have almost become the standard configuration in the takeaway industry. However, while this type of food box brings convenience to people, it also brings serious environmental problems. Foam lunch boxes are not easy to degrade and will exist in the natural environment for a long time, causing pollution to soil and water sources. In addition, the production process of foam lunch boxes will also emit harmful substances, posing a threat to human health.

Faced with this dilemma, developing countries must seek an alternative that can meet both economic development needs and protect the environment. And plastic lunch boxes may be a good choice. Compared with foam lunch boxes, plastic lunch boxes have higher strength and wear resistance, which can be reused and reduce waste generation. Meanwhile, the production process of plastic lunch boxes is relatively environmentally friendly and does not emit harmful substances.
