PET has the advantages of heat resistance, acid resistance and high strength. It is commonly used to make food packaging and beverage bottles. It does not release harmful substances at room temperature. It is one of the daily common packaging materials. PET is the abbreviation of Polyethylene terephthalate, the Chinese name is polyethylene terephthalate, commonly known as polyester. The materials that can be seen everywhere in daily life, such as various beverage bottles and mineral water bottles, are made of PET materials. Features of PET bottles:
1. It has good mechanical properties, the impact strength is 3~5 times that of other films, and the folding resistance is good. 2. Resistance to oil, fat, dilute acid, dilute alkali, and most solvents. 3. It can be used for a long time in the temperature range of 55-60℃, and can withstand high temperature of 65℃ and low temperature of -70℃ for short-term use, and its mechanical properties will be little affected at high and low temperatures. 4. The gas and water vapor permeability is low, and it has excellent gas, water, oil and peculiar smell performance. 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. Due to the non-toxic and high temperature resistance characteristics of the PET bottle itself, it is a safe substance that is harmless to the human body under normal temperature conditions and can be safely used for cold water, hot water, and beverages. |
