What is LDPE 2420D Plastics

LUPOLEN LDPE 2420D is a general-purpose low-density polyethylene ldpe plastic material launched by LyondellBasell. It has excellent mechanical properties and bubble stability and is widely used in blow molding extrusion applications such as flexible packaging, agricultural film, and stretch hood packaging. Its high melt strength and additive-free characteristics provide users with pure and high-performance ldpe plastics solutions.

01 | Three core features: stable foam, high strength, and universal adaptability

High melt strength and good bubble stability

LDPE 2420D plastic has a melt index of 0.25 g/10min, high melt strength, is not easy to collapse bubbles in film blowing, and has uniform film formation. It is particularly suitable for high barrel-diameter ratio, wide-width agricultural film or multi-layer co-extrusion middle layer.

Excellent mechanical strength and ductility

With a longitudinal tensile strength of 27 MPa, a vertical elongation at break of 500%, and a tensile modulus of 260 MPa, it has good support and tear resistance after film formation, making it very suitable for heavy packaging bags and stretch cover films.

Additive-free pure formula

This grade does not contain anti-blocking agents, lubricants or antistatic additives, and is suitable for customers with high purity requirements, such as food-grade packaging or companies that need to customize modified masterbatch ratios.

02 | In-depth exploration of application areas: multiple values ​​from packaging bags to agricultural films

▶ Flexible packaging and heavy packaging bags

High toughness and good processability make it outstanding in industrial packaging bags and building materials packaging films, able to withstand handling shocks and maintain a firm seal.

▶ Agricultural film application

LDPE 2420D's good transparency and puncture resistance (6.5 J/mm) make it suitable for use in fields such as agricultural land covering films and greenhouse films, maintaining mechanical integrity and service life under different climatic conditions.

▶ Stretch hood film and shrink film

On the automated shrink packaging line, LDPE 2420D exhibits good heat shrink consistency and uniform stretching performance, and can be used for assembly outsourcing protection in the beverage, home appliance and other industries.

▶ Blown film and liner film

Suitable for express bags, envelope films, shopping bags, industrial liner bags, etc., meeting the production requirements of high strength, no impurities, and uniform thickness.

03 | Processing suggestions and precautions

Film blowing temperature control: It is recommended that the barrel temperature be 170–200°C, and the die temperature be slightly higher to stabilize the inflation ratio;

Thickness recommendation: Suitable for various film products of 40–100μm;

Extrusion application: It can be used as a co-extrusion film substrate layer, and it is recommended to be matched with EVA or mPE to improve flexibility;

Processing equipment matching: It is suitable for all mainstream extrusion and film blowing equipment, with stable fluidity, easy thickness control and die uniformity.

05 | Comparative Analysis with Other General-Purpose LDPE Grades

06 | Sustainable perspective: energy saving and controllable formula

LUPOLEN LDPE 2420D helps customers ensure physical properties while controlling melt index and modulus parameters:

Realize film weight reduction: increase finished product area per unit weight and reduce material waste;

Customized additive system: blank formula allows users to develop modified grades such as anti-purple and anti-fog on demand;

Reduce processing energy consumption: low MI design reduces shear heat and is suitable for long-cycle, energy-saving production lines;

Compatible with recycling: can be blended and reused with PE recycling system to help build a closed-loop packaging system.

07 | Real scenario cases of downstream customers

Case 1: A large flexible packaging company uses LDPE 2420D to replace a variety of low-performance film materials, reducing film thickness by 12% and improving the unit tensile performance of packaging bags by 18%.

Case 2: Southeast Asian agricultural film manufacturers reported that greenhouse films made of LDPE 2420D plastics still maintain good ductility and stability in high temperature and high humidity climates, and no film breakage was found.
