Low-density polyethylene (LDPE) plastic film and cling film have good barrier properties against water, so paper boxes such as milk cartons and beverage boxes are used as inner film. Because the low-density polyethylene wrap film will be hot-dissolved when it exceeds 120 °C, if the wrap is used to wrap the food, the oil in the food will melt some of the ingredients in the wrap, so it is necessary to keep it fresh before entering the microwave oven. The membrane is removed, at least not allowing the food to directly contact the cling film. Low-density polyethylene itself has no degradation properties, and today's “plastic limit” is mainly limited.
