The main difference between PET cup and ordinary cup lies in the material, applicable scene and safety.
Material and characteristics
PET cup: PET cup is made of polyethylene terephthalate. It is light, transparent and durable, but not suitable for repeated use or hot water, because PET material is not heat-resistant and easily releases harmful substances when heated over 70 degrees Celsius. Ordinary cup: There are many types of materials for ordinary cups, including PP (polypropylene), PS (polystyrene), PC (polycarbonate), etc. These materials have their own advantages and disadvantages. For example, PP material is resistant to high temperature, non-toxic and odorless, suitable for hot water and microwave heating; PS material is transparent but brittle, often used in disposable water cups; PC material is impact-resistant but needs to avoid high temperature. Applicable scene PET cup: Suitable for cold drinks such as lemon tea, iced coffee, etc., because of its high transparency and lightness, it is often used for one-time use or short-term repeated use. Ordinary cup: Depending on the material, the applicable scene is also different. For example:
PP cup: suitable for high-temperature drinks, cold drinks and juices, etc., because it is resistant to high temperatures and non-toxic and odorless.
PS cup: suitable for low-temperature drinks and juices, but not recommended for hot drinks.
PC cup: suitable for daily use, but care should be taken to avoid high temperatures.
Safety and environmental protection
PET cup: although light and transparent, it is not suitable for high-temperature liquids, and should be recycled after use to reduce environmental pollution.
Ordinary cup: the safety of different materials varies greatly. For example:
PP cup: resistant to high temperatures, non-toxic and odorless, suitable for microwave heating, and a good choice for environmental protection.
PS cup: transparent but brittle, and may release harmful substances, it is recommended to reduce its use.
PC cup: impact-resistant but need to avoid high temperatures, care should be taken when using it.
