Physical Properties Explained

The physical characteristics of LDPE LFI 2119 directly influence its processing behavior and the performance of the final packaging film. Understanding these properties helps converters select the most suitable material for their production requirements.

Density

LDPE LFI 2119 has a density of 0.921 g/cm³, placing it within the ideal range for flexible blown film production.

This density contributes to several important advantages, including improved softness, better flexibility, enhanced heat-sealing performance, and lower film weight. It also helps produce films that maintain an excellent balance between mechanical strength and optical clarity.

Lower-density polyethylene generally provides greater flexibility than higher-density polyethylene grades, making it particularly suitable for applications where repeated folding, stretching, and handling are required.

Melt Flow Index (MFI)

The Melt Flow Index (MFI) of LDPE LFI 2119 is 1.9 dg/min, measured at 190°C under a 2.16 kg load according to ISO 1133.

This value is carefully optimized for blown film extrusion.

A controlled melt flow allows processors to maintain stable bubble formation while producing films with consistent thickness and uniform mechanical properties.

Benefits of this MFI include:

✔ Excellent extrusion stability

✔ Uniform gauge control

✔ Smooth resin flow

✔ Better production efficiency

✔ Reduced risk of melt fracture

✔ Improved dimensional consistency

For manufacturers operating high-capacity blown film lines, a stable MFI contributes directly to higher productivity and reduced material waste.

Mechanical Properties Explained

Mechanical performance is one of the primary reasons why LDPE LFI 2119 is widely used in premium packaging films. The resin combines flexibility with excellent resistance to impact and tearing, ensuring reliable performance throughout the product’s life cycle.

High Impact Strength

LDPE LFI 2119 offers an impact strength of 26 kJ/m², enabling films to absorb sudden mechanical shocks without failure.

During transportation, storage, and pallet handling, packaging materials are frequently exposed to impacts from boxes, pallets, or handling equipment. A high impact strength minimizes punctures and reduces the likelihood of package failure, protecting both the packaged product and the manufacturer’s reputation.

This property is especially valuable for industrial packaging, agricultural films, and heavy-duty bags where durability is essential.

Excellent Tear Resistance

One of the most important characteristics of blown film materials is resistance to tearing.

LDPE LFI 2119 provides:

Machine Direction (MD): 60 kN/m
Transverse Direction (TD): 25 kN/m

This balanced tear resistance helps films withstand mechanical stress during filling, transportation, and daily use. Strong tear resistance also extends the service life of packaging materials while reducing product losses caused by accidental tearing.

Elastic Modulus

The elastic modulus values of approximately 200 MPa (TD) and 190 MPa (MD) provide an ideal balance between stiffness and flexibility.

This allows films to maintain their shape while remaining flexible enough for packaging applications that require folding, stretching, or repeated handling.

Proper stiffness also contributes to improved machinability during automatic packaging operations.

Optical Properties Explained

The visual quality of flexible packaging plays an essential role in attracting consumers and improving product presentation. LDPE LFI 2119 has been engineered to produce films with excellent transparency and surface appearance, making it suitable for premium packaging applications.

Low Haze

LDPE LFI 2119 has a haze value of only 9%, allowing the production of highly transparent films.

Low haze improves product visibility inside the package, making it particularly valuable for retail packaging where customers prefer to clearly see the packaged goods before purchasing. High transparency also enhances the overall appearance of food packaging, bakery products, fresh produce, and consumer goods.

High Surface Gloss

Besides transparency, LDPE LFI 2119 provides an attractive glossy finish with a surface gloss of approximately 55 Gloss Units (GU).

A glossy surface gives packaging a cleaner and more premium appearance while improving print quality for branding, graphics, and product information. Manufacturers producing high-end packaging often select materials with excellent gloss to increase shelf appeal.

Processing Characteristics

LDPE LFI 2119 has been specifically designed for stable blown film extrusion and consistent production performance. Its rheological properties enable smooth processing across a wide range of production conditions.

Recommended Processing Conditions

Parameter	Recommended Range
Extruder Temperature	165–185°C
Blow-Up Ratio (BUR)	2–3
Film Thickness	20–50 μm

For optimum production results, processors should maintain stable cooling conditions, uniform die temperature, and consistent screw speed throughout the extrusion process.

Proper process control provides several advantages:

✔ Stable bubble formation

✔ Excellent gauge uniformity

✔ Reduced film defects

✔ Improved optical quality

✔ Higher production efficiency

✔ Lower scrap rates

Avoiding excessive machine-direction orientation also helps preserve the resin’s excellent tear resistance and transparency.
