ПСТ — це поліетилен середнього тиску: властивості та застосування
PST stands for medium-density polyethylene. It occupies an intermediate position between high-density polyethylene (HDPE) and low-density polyethylene (LDPE). Thanks to its properties, PST combines flexibility and strength, making it a popular material in the packaging industry.
What is medium-density polyethylene?
PST is produced through the polymerization of ethylene at medium pressure (from 5 to 30 atm) and a temperature of 80–120°C. In terms of its physical and chemical properties, it is closer to LDPE, but has higher density and improved resistance to mechanical stress.
Main properties of PST (medium-density polyethylene)
- Flexibility – the material bends easily, ideal for thin films;
- Strength – withstands mechanical loads without tearing;
- Puncture and stretch resistance – important for packaging;
- Good weldability – easily sealed and formed into bags;
- Optical clarity – maintains a clean, aesthetic appearance of the packaging;
- Chemical resistance – does not react with most substances.
Where is medium-density polyethylene used?
- Production of polyethylene bags – such as produce bags, T-shirt bags, branded bags;
- Packaging film for food and technical products;
- Inserts and sacks for industrial applications;
- Packaging for textiles, clothing, paper products;
- Multilayer COEX bags with a PST layer for enhanced strength.
