Transparent hard anti fog PET plastic sheet roll

Specification of Transparent hard anti fog PET plastic sheet roll

Advantages of PET as a packaging material:
1. It has good mechanical properties, impact strength is 3 to 5 times that of other films, and good folding resistance.
2. Resistance to oil, fat, dilute acid, dilute alkali, and most solvents.
3. It has excellent resistance to high and low temperatures. It can be used for a long time in the temperature range of 120°C, and can withstand high temperature of 150°C and low temperature of -70°C in short-term use, and the mechanical properties of high and low temperatures have little effect.
4. The gas and water vapor permeability is low, and it has excellent gas, water, oil and odor resistance.
5. High transparency, can block ultraviolet rays, and good gloss.
6. Non-toxic, tasteless, good hygiene and safety, and can be directly used for food packaging.
 
Characteristics of PET as a packaging material:
PET is a milky white or light yellow highly crystalline polymer with a smooth and shiny surface. Creep resistance, fatigue resistance, good abrasion resistance and dimensional stability, low abrasion and high hardness, have the greatest toughness among thermoplastics: good electrical insulation, low temperature influence, but poor corona resistance. Non-toxic, weather resistance, good chemical resistance stability, low water absorption, resistance to weak acids and organic solvents, but not immersed in hot water and alkali. PET resin has a high glass transition temperature, slow crystallization speed, long molding cycle, long molding cycle, large molding shrinkage, poor dimensional stability, and crystallization molding is brittle and low heat resistance. Through the improvement of nucleating agent and crystallization agent and glass fiber reinforcement,
In addition to the properties of PBT, PET has the following characteristics:
1. The heat distortion temperature and long-term use temperature are the highest among thermoplastic general engineering plastics;
2. The bending strength is 200MPa, the elastic modulus reaches 4000MPa, the creep and fatigue resistance are also very good, the surface hardness is high, and the mechanical properties are similar to thermoset plastics;
3. Since the ethylene glycol used in the production of PET is almost half the price of the butylene glycol used in the production of PBT, PET resin and reinforced PET are the cheapest among engineering plastics and have a high cost performance.
