Plastic Boxes, as common storage and carrying tools in our daily lives, actually contain complex material choices behind them. So, what type of plastic are Plastic Boxes made of?
First of all, we need to understand that plastic is a general term for a class of polymer compounds. These polymer compounds can be made into plastic products of various shapes and functions after specific processing, such as heating and pressing. For Plastic Boxes, commonly used plastic materials include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), etc.
Polyethylene (PE) is a common plastic material with excellent low temperature resistance, chemical stability and good wear resistance. Therefore, Plastic Boxes made of polyethylene are usually soft, cold-resistant, transparent and suitable for food packaging and refrigerated storage.
Polypropylene (PP) is another common plastic material with high heat resistance, wear resistance and transparency. This allows polypropylene Plastic Boxes to be used in high-temperature environments, such as microwave heating, and easy to clean, making them suitable for food packaging and daily necessities storage.
Although polyvinyl chloride (PVC) is also commonly used in the production of plastic products, it is not suitable for use in food packaging and containers that come into direct contact with food because it may release harmful substances during heating and processing. However, PVCPlastic Boxes are still used in some special fields, such as raincoats, building materials, etc.
In short, Plastic Boxes have a variety of material options, and Plastic Boxes of different materials have different characteristics and applicable scenarios. When choosing Plastic Boxes, we need to choose appropriate materials based on actual needs and use environment to ensure their safety, reliability, and durability.
