Summer is here, the weather is getting hotter and hotter, and food preservation has become a thorny issue. How to preserve food reliably and safely, I believe everyone will use plastic wrap. Every time I enter the supermarket, I am dazzled by the dazzling array of shelves in front of the shelves.
The main component of PE Cling Film is polyethylene resin, which is mainly used for packaging of ordinary fruits and vegetables. PE Cling Film is considered a safe packaging material for packaging food that comes into direct contact. PE cling film has good waterproof and air permeability, and is suitable for packaging fresh vegetables and frozen foods. However, due to its good air permeability, it is not suitable for packaging foods with high fat and flavor that are easily damaged by oxygen. Cling Film Food has the advantages of preventing food odor, reducing bacterial contamination and maintaining food nutrition. It has a certain degree of air permeability and limits the loss of water, can adjust the oxygen content and moisture content around the food, and at the same time block dust and bacterial contamination to a certain extent, thereby prolonging the freshness period of the food.
But it is not a "universal product" for food preservation. Plasticizers will dissolve into food in water or oil above 60°C, so it is best not to use plastic wrap to preserve cooked food and food containing a lot of oil. Fruits and vegetables with high water content are more suitable for preservation with plastic wrap, such as apples, pears, watermelons, etc. When purchasing plastic wrap, it is recommended to choose Pe Cling Film For Food, especially when it is used for meat, fruit and other foods.
