Awareness notice: plastic containers should be recycled
The use of plastic packaging materials is closely related to the lifestyle of modern industrial and commercial society. Due to the rapid growth of the population and its concentration in cities, it has become very important to use lightweight packaging to facilitate the storage and transportation of items and increase the shelf life of items.
Plastic packaging materials can just meet these needs. Due to the low density of plastic, the weight is much lighter than metal or glass, making it easier to process or use. Plastic has strong toughness and is not as easily broken as glass, unlike cans that are easily dented when under pressure, and unlike paper that is easily torn, so it has become a commonly used packaging method for many modern commodities.
Plastic is a polymer material made from the polymerization of many so-called "monomers". Each has its own special properties due to its different structure. There are many types of plastics commonly used in food packaging containers, including polyethylene (PE), polyethylene (PE), Propylene (polypropylene, PP), polyvinyl chloride (PVC), polystyrene (PS), etc., all have different properties.
Polyethylene Terephthalate (PET) was originally used as a raw material for textiles. It has only been widely used in plastic containers across borders in the past two decades.
