When choosing plastic bags, it is essential to understand the differences between polyethylene (PE) and polypropylene (PP). Both materials offer unique advantages based on your packaging needs and applications.
PE Bags (Polyethylene Bags)
Composition:
PE bags are made from polyethylene and are divided into two types: LDPE (Low-Density Polyethylene) and HDPE (High-Density Polyethylene).
Appearance:
PE bags typically have good transparency and gloss, along with a soft texture.
Flexibility:
PE bags exhibit excellent flexibility, with high elongation at break and strong impact resistance.
Temperature Resistance:
They can function effectively within a temperature range of -80°C to 80°C.
Chemical Stability:
PE bags are highly resistant to acids, alkalis, and organic solvents.
PP Bags (Polypropylene Bags)
Composition:
PP bags are composed of polypropylene.
Appearance:
These bags are known for their higher transparency, harder texture, and a brittle feel.
Flexibility:
PP bags are less flexible, with a lower elongation at break; however, they possess high rigidity and strength.
Temperature Resistance:
They are effective at high temperatures, suitable for use in the range of -20°C to 120°C.
Chemical Stability:
PP bags demonstrate good resistance to various chemicals but can become brittle at low temperatures.
Applications of PE Bags
Food Packaging: Ideal for frozen food and preservation bags due to their flexibility and moisture resistance.
Daily Necessities Packaging: Commonly used for shopping bags and garbage bags because of their excellent load-bearing capacity and durability.
Industrial Product Packaging: Used for packaging electronic components and chemical raw materials, thanks to their chemical resistance and dust/mud moisture resistance.
Applications of PP Bags
High Transparency Packaging: Used for gift bags and garment bags, appreciated for their high aesthetic value.
Thermal Products Packaging: Suitable for microwave food packaging bags due to their excellent high-temperature resistance.
Rigid Packaging: Commonly employed for items such as bottle caps, containers, and household goods packaging owing to their high rigidity and strength.
Tensile Strength:
PE Bags: 20-30 MPa
PP Bags: 30-40 MPa
Elongation at Break:
PE Bags: 400% or more
PP Bags: 100%-300%
Temperature Resistance Range:
PE Bags: -80°C to 70°C
PP Bags: -20°C to 120°C
Chemical Stability:
PE Bags: Good resistance to acids, alkalis, and organic solvents.
PP Bags: Good resistance to various chemicals but tends to become brittle at low temperatures.
