Foil container obvious benefits to people's lives and the environment, but this meal is always in "were praised" position. The experts believe that the constraints foil container promotion there are three reasons, first, the problem of prices and costs, recycling, is a question of perception.

The cost has been a major reason for restricting the promotion of foil container. Shanghai Restaurants Association experts Xiaxiang Qing said, aluminum products has not only reduced the original packaging waste, has also been recognized by consumers, but restaurant owners generally reflect the cost of the "foil container",. Foil container price higher than the disposable plastic lunch boxes nearly 1/3, taking into account the cost of many food businesses, "discouraged".

The cost of the lunch boxes is any catering enterprises must be considered, but in fact, if we consider the cost of the integrated use of foil container is not higher than the disposable plastic lunch boxes.

Experts, 20 weight aluminum foil container, for example: each priced at $ 0.80, after recycling prices, recycling prices by 0.011 yuan / g each product the cost of the actual use of $ 0.58 to $ 0.22, close to standards, health and environmental cost of lunch boxes. If the amount of energy saving through lunch heating process will further reduce consumer costs, and the vast majority of the huge social costs of eliminating the need for recycling plastic lunch box. For example, with infrared food steam box heating 100 aluminum foil container, equivalent to the electricity bill, 100 heated in a microwave plastic lunch boxes, equivalent to the electricity needs. Such a ratio, aluminum foil container one-time purchase cost is higher, but the subsequent use of lower energy consumption, recycling also enjoy government subsidies, the overall cost is not higher than the plastic lunch boxes. Zhangsong Yue also suggested that by supporting the processing equipment can also change overpriced. He believes that if the scale of production is more than ten thousand a day, rent, manpower and energy consumption can be reduced basically to digest part of the higher costs.
