Stretch Wrap : LLDPE (Linear Low-Density Polyethylene)

LLDPE (Linear Low-Density Polyethylene) is a type of PE (polyethylene plastic) which is a plastic that combines properties of both LDPE (Low-Density Polyethylene) and HDPE (High-Density Polyethylene).

Key Characteristics:

• More flexible than HDPE
• Stronger than regular LDPE
• Better puncture resistance
• Good stretch properties
• High resistance to tear 

Common Uses:

• Stretch wrap
• Food packaging films
• Agricultural films
• Heavy-duty bags
• Cable insulation
• Toy parts

Processing Benefits:

• Easy to process
• Good melt strength
• Works well in film extrusion
• Can be blended with other PEs
• Good for thin films

Film Extrusion: A manufacturing process where melted plastic pellets are pushed through a shaped opening called die to create a thin, continuous sheet or tube of plastic film. 

The plastic cools down and solidifies into products like plastic bags, wraps, and packaging materials.

PE (Polyethylene): A common plastic material available in low and high densities and is used to make products like plastic bags, bottles, and packaging films. It's known for being flexible, durable, and water-resistant.

LLDPE combines 

• Characteristics from HDPE and LDPE 
• More flexible than HDPE (milk jugs)
• Stronger than LDPE (shopping bags)
• Better for products that need material that can stretch

Given the above characteristics, it is often used in application that need both strength and flexibility
