The packaging industry, as an important link in commodity circulation, its production efficiency and product quality are directly related to the market competitiveness of enterprises. In this field, organic silicon release agents quietly contribute and become a key factor in ensuring the smooth molding of packaging materials.
In the injection molding process of plastic packaging containers, the role of organic silicon release agents is like a magical "separation magic". When the high - temperature plastic melt is injected into the mold cavity, the organic silicon release agent quickly forms a dense isolation film on the mold surface. This film is like an invisible "lubricant". When the plastic product cools and solidifies, it can be easily removed from the mold, avoiding problems such as product deformation and surface scratches caused by difficult demolding. For example, when producing plastic beverage bottles, if the release effect is not good, the beverage bottles may have defects such as irregular bottle mouths and wrinkled bottle bodies, affecting the appearance and sealing performance of the product. The use of organic silicon release agents makes the demolding process of beverage bottles smooth and efficient, and the product qualification rate can be increased to more than 95%.
For the production of paper packaging, organic silicon release agents are equally indispensable. Taking the production of paper cups as an example, during the die - cutting and molding process of paper cups, the paper needs to be bent and pressed multiple times in the mold. Organic silicon release agents can prevent the paper from sticking to the mold, ensuring that each paper cup can be perfectly formed with a smooth and flat surface. In addition, with the deepening of the concept of environmental protection, the packaging industry has also put forward higher requirements for the environmental performance of organic silicon release agents. Currently, many new environmentally friendly organic silicon release agents have emerged on the market. They use biodegradable raw materials or low - VOC (volatile organic compounds) formulations, minimizing the negative impact on the environment while meeting the production needs of the packaging industry, providing strong support for the sustainable development of the packaging industry.
