Food packaging trays and drinking water cups

PP (polypropylene), PS (polystyrene) and PET (polyethylene terephthalate) are common plastic materials that are widely used in food packaging and disposable water cups: PP is a high-quality High performance, versatile plastic material with excellent thermal properties and tensile strength suitable for heat sealing and microwave heating.  In terms of food packaging, PP is often used to make food boxes, plastic bags, plastic wrap, etc. because it has excellent sealing and heat resistance and can maintain the freshness and hygiene of food.  PP is also often used as a material when it comes to disposable water cups. PP disposable cups usually have the characteristics of high transparency, good heat resistance, and not easy to deform, and are suitable for holding hot and cold drinks. PS is a common plastic material with good transparency and gloss, and is usually used to make transparent plastic products.  In terms of food packaging, PS is often used to make transparent food boxes, plastic wrap, tableware, etc., and can also be used to make transparent disposable beverage cups. PS disposable water cups usually have the characteristics of high transparency and light texture, and are suitable for holding cold drinks and beverages. PET is a common transparent plastic with good heat resistance, mechanical properties and transparency that is commonly used to make bottles and containers.  In terms of food packaging, PET is often used to make beverage bottles, juice bottles, food cans, etc. because it has excellent acid and alkali resistance, transparency and corrosion resistance, and can safely package food and beverages.  PET is also commonly used as a material when it comes to disposable water bottles. PET disposable water cups usually have the characteristics of high transparency, good rigidity, and resistance to deformation, and are suitable for holding cold drinks and beverages.  When selecting materials for food packaging and disposable water cups, factors such as the characteristics, use, safety, and environmental friendliness of the materials need to be considered to ensure that the materials meet the usage requirements and will not cause too much negative impact on the environment.
