Study on the breathable properties of bis-(2-dimethylaminoethyl) ether in food plastic wrap<\/h1>\n

Introduction<\/h2>\n

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

Overview of bis-(2-dimethylaminoethyl)ether<\/h2>\n

Chemical structure and properties<\/h3>\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

Application Fields<\/h3>\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 properties of food plastic wrap<\/h2>\n

Definition of breathable performance<\/h3>\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

Factors influencing breathability<\/h3>\n
    \n
  1. Material properties<\/strong>: The breathable properties of different materials vary greatly. For example, polyethylene (PE) and polyvinyl chloride (PVC) have different breathability. <\/li>\n
  2. Thickness<\/strong>: The thickness of plastic wrap directly affects its breathable performance. Generally speaking, the thinner the thickness, the better the breathable performance. <\/li>\n
  3. Adjusting<\/strong>: The type and amount of additives will also affect the breathable performance of plastic wrap. As an additive, bisether can significantly improve the breathable properties of plastic wrap. <\/li>\n<\/ol>\n

    The application of bis ether in food plastic wrap<\/h2>\n

    How to add bis ether<\/h3>\n

    Diesel ethers can be added to plastic wrap by:<\/p>\n

      \n
    1. Direct mix<\/strong>: Mix bis ether directly with a plastic wrap base material (such as polyethylene) and prepare plastic wrap through an extrusion molding process. <\/li>\n
    2. Surface coating<\/strong>: Coat the bis ether solution on the surface of the plastic wrap and cure it by drying to form a breathable film. <\/li>\n<\/ol>\n

      Influence of bis ether on breathable properties of plastic wrap<\/h3>\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\n\n\n\n\n\n\n\n

      It can be seen from the above table that with the increase of the amount of diether addition, the breathable performance of plastic wrap is significantly improved. <\/p>\n

      The influence of bis ether on other properties of plastic wrap<\/h3>\n

      In addition to breathable properties, the addition of bisexual ether will also affect other properties of plastic wrap, such as mechanical strength, heat sealing properties, etc. The following is the relationship between the amount of bis ether added and the mechanical strength of plastic wrap:<\/p>\n\n\n\n\n\n\n\n\n
      Disether addition amount (%)<\/th>\nTension Strength (MPa)<\/th>\nElongation of Break (%)<\/th>\n<\/tr>\n
