Recubrimiento de la hoja de plástico antifog APET para escudo de cara

APET has a highly symmetrical molecular structure and a certain crystal orientation ability, so it has high film-forming properties and properties. PET has good optical properties and weather resistance, and amorphous PET has good optical transparency. In addition, PET has excellent wear resistance, friction, dimensional stability and electrical insulation. PET bottles have high strength, good transparency, non-toxic, anti-permeation, light weight, high production efficiency, etc., so they are widely used. The molecular chain structure of PBT and PET is similar, and most of the properties are the same, except that the main molecular chain has changed from two methylene groups to four, so the molecules are more flexible and processing performance is better.

Advantages of APET as a packaging material:
1. Tiene buenas propiedades mecánicas, la resistencia al impacto es de 3 a 5 veces mayor que la de otras películas y una buena resistencia al plegamiento.
2. Resistencia al aceite, grasa, ácido diluido, álcali diluido y la mayoría de los solventes.
3. With excellent resistance to high and low temperatures, it can be used for a long time within the temperature range of 120°C, and can withstand high temperatures of 150°C and low temperatures of -70°C in short-term use, and has little effect on its mechanical properties at high and low temperatures.
4. La permeabilidad del vapor de gas y agua es baja, y tiene una excelente resistencia al gas, el agua, el petróleo y el olor.
5. Alta transparencia, puede bloquear los rayos ultravioleta y un buen brillo.
6. No tóxico, insípido, buena higiene y seguridad, y se pueden usar directamente para el embalaje de alimentos.
