Disposable fast food container are loved by people because of their convenience, and can be seen everywhere in daily life. At present, the disposable snack boxes on the market are mostly made of foam fast food container machine, and polystyrene material extracted from petroleum and foaming agent, heated and foamed. Polystyrene is a widely used macromolecule material with low toxicity, high melting point, strong plasticity and easy production, so it has become the preferred material for making disposable fast food boxes.
Foamed lunch boxes are more environmentally friendly. The identity of foamed lunch boxes may be changed from "semi-underground" to "legalized". Recycling economy is expected to be gradually reflected in the field of fast food boxes. Recently, the Green Packaging Branch of the Chinese Society of Environmental Sciences called for a wrongful call for disposable foamed plastic lunch boxes. They say "Disposable foam plastic lunch boxes are more environmentally friendly than the so-called" environmentally-friendly tableware "from the production of foam fast food container machine
to the use and recycling.
What are the advantages of foamed lunch boxes? Comparing the price and performance of these kinds of lunch boxes, we can find that disposable foamed plastic lunch boxes have certain advantages. According to the production and related data of the foam fast food container machine, the price of the foaming lunch box is the lowest, 0.06-0.07 yuan, and the cardboard compound film box price is the highest, which is 0.30-0.38 yuan. In addition to higher cost performance, disposable foamed plastic lunch boxes are also better than environmentally friendly ones in terms of heat preservation, strength and other performance indicators. Disposable foamed plastic lunch boxes can keep food warm for up to 4 hours without distortion; paper lunch boxes or vegetable fiber lunch boxes can only keep food warm for up to 1 hour, and they are easily deformed by Chinese dish pickles with soup and water. These advantages of disposable foamed plastic lunch boxes have also become an important reason for the difficulty of enforcing the local ban.
