What kind of tableware can be called a one-time degraded meal

   There are many materials for takeaway lunch boxes, such as pe, pct, pp, etc., and environmentally friendly injection boxes are many. Previous disposable lunch boxes were made of the same material as plastic. High temperatures produced harmful substances and were not easily degraded. The current environmentally-friendly tableware mainly consists of PP polypropylene and PS polystyrene. They are non-toxic, tasteless and odorless. PP is soft. Generally, the PP temperature is -6 degrees to +120 degrees, so it is especially suitable for hot. Hot rice dishes can be heated in a microwave oven or even cooked in a steam cabinet. The modified PP can be used at temperatures ranging from -18 degrees to +110 degrees. The lunch box made of this PP can be heated to 100 degrees. In addition, it can be placed in the refrigerator for refrigerating use. Reusable plastic tableware is not only practical, lightweight, but also flexible, and the price ranges from cheap to expensive. It depends mainly on design, quality, etc. There are a large number of designs and sizes to choose from.

   In addition, PS material tableware and lunch boxes are hard and transparent, but they are easy to tear. PS starts to soften when the temperature reaches 75 degrees, so it is not suitable for hot rice hot dishes, but the low temperature performance of PS is very good. Very good ice cream packaging material. Therefore, it can also be called environmental tableware!



   It is understood that the chemical name of the disposable degradation lunch box material is called polyethylene or polypropylene. It has low strength and cannot withstand high temperatures above 80 °C, and has a certain gas permeability. We can use the sensory and combustion methods to identify their toxicity. details as follows:

After leaving the fire, slowly let go of the hope that consumers can pay attention to distinguish, do not misuse toxic plastic packaging.
