Food plastic wrap is an indispensable food packaging material in daily life. Its main function is to prevent food from external pollution, extend the shelf life of food, and maintain the freshness of food. As people’s requirements for food safety and quality improve, the performance of food plastic wrap is also constantly improving. Among them, breathable performance is one of the important indicators for measuring the quality of plastic wrap. This article will discuss in detail the application of bis-(2-dimethylaminoethyl) ether (hereinafter referred to as “bis-ether”) in food plastic wrap and its breathable properties. <\/p>\n
Bis-(2-dimethylaminoethyl)ether is an organic compound, and its chemical structural formula is: (CH3)2N-CH2-CH2-O-CH2-CH2-N(CH3)2. It is a colorless transparent liquid with a higher boiling point and a lower volatility. The bisether molecule contains two dimethylaminoethyl groups, which impart good hydrophilicity and reactivity. <\/p>\n
Di-ethers are widely used in chemical industry, medicine, food and other fields. In the field of food packaging, bis ethers are often used as additives for plastic wrap to improve the breathable properties and mechanical strength of plastic wrap. <\/p>\n
Breathable performance refers to the ability of plastic wrap to allow gases (such as oxygen, carbon dioxide, etc.) to pass through. Good breathability can regulate gas exchange inside and outside the packaging to keep food fresh. <\/p>\n
Diesel ethers can be added to plastic wrap by:<\/p>\n
The addition of bis ether can significantly improve the breathable performance of plastic wrap. The following is the relationship between the amount of bis ether added and the breathable properties of plastic wrap:<\/p>\n
