Polyethylene (PE) is one of the most commonly used types of plastic in various applications due to its versatile and durable properties. PE is known for being lightweight, corrosion-resistant, resistant to various chemicals, as well as having resistance to weather and extreme temperatures.
There are several main types of Polyethylene, including:
- Low-Density Polyethylene (LDPE): LDPE has low density and is very flexible, making it suitable for the production of plastic bags, food containers, and other flexible items. LDPE can also be easily molded and has good wear resistance.
- Ultra-High-Molecular-Weight Polyethylene (UHMWPE): UHMWPE has a very high molecular mass, giving it properties such as low wear, impact resistance, and good sliding properties. It is commonly used in applications that require friction and wear resistance, such as ski glide plates and machine components.
- Linear Low-Density Polyethylene (LLDPE): LLDPE is a variant of LDPE with a more linear molecular structure. This provides higher strength and wear resistance than LDPE. LLDPE is often used for plastic bags, stretch films, and other flexible containers.
Characteristics of good PE (Polyethylene) plastic bags include:
- Not easily torn and worn
- Flexibility (elastic/flexible)
- Resistant to water, oil, coconut milk, and chemicals
- Lightweight and strong
- Slightly cloudy and transparent
- Clean, hygienic, and odorless
- Resistant to UV radiation
- Recyclable
