PE/PA/PE composite stretch film
Stretch film for microwave oven is a new special stretch elastic film. When a microwave oven heats food, the smell, soup, and oil in the food will be emitted and sputtered into the microwave oven, and even enter the internal circuit of the microwave oven, so that the inside of the microwave oven is easily dirty, affecting the flavor of the food, and using a stretch elastic film, The situation has changed a lot. However, the general cling film has insufficient heat resistance and is scalded. Therefore, people are actively developing a stretch elastic film suitable for microwave ovens.
To be suitable for the stretch film of microwave ovens, two main problems must be solved: 1 heat resistance, because of heating in a microwave oven, there is a high requirement for the heat resistance of the film, so it is required to select a heat-resistant resin. In foreign microwave oven stretch film, use PE / PA / PE composite method to improve heat resistance; 2 food extractability, microwave oven heating, the temperature of oil, water, acid in food is increased to 100 ° C, even 100 ° C Above, their extraction effect is greatly increased, so that the possibility of the additive added to the stretched elastic film being extracted into the food is greatly increased, so the additive of the film is less added, and the use condition must be paid attention to when it is added. Extractability under.
The co-extrusion composite elastic film with PE/PA/PE has high difficulty in designing and processing the machine head. Therefore, the method of adding special additives in PE is adopted. This special additive is not easily dissolved in oil, water and alcohol. ,acid.
The method for measuring the heat resistance of a film is to use an edible oil (for example, 130 ° C) heated to a certain temperature, and drop three drops on the film to see if the film is scalded by the high-temperature edible oil and the lowest temperature to be burned by the edible oil. For extreme temperatures.
This kind of film has been used practically, and the effect is good. For example, in the 759W power microwave oven, the food is hot, the soup is boiling, but the film is not burnt.
