What Is LDPE Injection Molding?
LDPE injection molding is a low-density polyethylene that is specially designed to be used in injection molding and is offered as free-flowing polymer granules, with regulated viscosity and shrinkage. Its branched molecular structure makes it low in crystallinity, hence flexible, tough, and low corrosion melting temperatures compared to more crystalline polyethylenes.
Major Characteristics
Major characteristics of LDPE injection moulding polymer granules are:
- 910–0.930 g/cm 3 of soft, flexible components.
- Melting point similar to 105-115 °C, which allows moderate temperatures of processing and energy conservation.
- Aspects of excellence include impact and stress crack resistance, which are suitable for squeeze and snap fit parts.
Main Benefits For Processors And Users
Injection molding with low-density polyethylene offers many benefits in terms of processability, performance of the part, and cost. These are the strengths that LDPE injection molding grade offers to high-volume manufacturers in packaging, consumer, medical, and other industries.
Key advantages:
- High degree of flexibility and toughness: The parts are able to bend and deform without breaking and enhancing user comfort and safety.
- Good chemical and moisture resistance: can be used in a wide range of detergents, household chemicals, cosmetics, and food contact packaging (depending on grade).
- Simple flow and thin wall: Low viscosity in the melt permits complicated geometries, long distance flow paths, and thin cuts with stable filling.
- Low density and cost effectiveness: Lightweight components save material usage and logistics expenses and ensure durability.
LDPE Injection Molding Grade
Here are some of the provided LDPE inj molding grade resin:
- LDPE LIM1922: This is a dedicated LDPE injection‑molding grade. It is designed for parts like caps and closures, lids, household items, and toys, and has a high melt‑flow rate for fast filling and short cycle times.
- LDPE 1922T: This can be very close to LIM1922 and sometimes are used for injection molding and masterbatch, but you must check each producer’s datasheet to see if injection molding is clearly listed as a main application. If the datasheet only talks about film, it is not a true injection‑molding grade. You

The following table summarizes typical property ranges for LDPE injection molding grade used in caps, closures, and small technical parts:
Typical Uses of LDPE Injection Molding Grade
Where softness, impact damping, and chemical resistance are more required than stiffness, LDPE injection molding grade is employed. LDPE injection molding polymer granules are the best to use where there is a high level of cavitation, as well as mass production, because they are both fast and reliable.
Key application areas:
- Packaging items: Caps and closures, lids, dosing plugs, dispensers, and small food, personal care, household chemicals, and agrochemicals containers.
- Consumer goods and toys: Flexible housings, squeeze bottles, handles, protective bumpers, and toy parts that must be soft but durable.
- Medical and laboratory components: Some grades are in disposable medical equipment and containers, laboratory accessories, and flexible components, and are subject to regulatory approvals.
- Electrical and electronics: Small insulators, grommets, cable handling components, and low voltage housings that need dielectric behaviour and bending capability.
- Building and industrial Fittings: Protective tops, plugs, and light-duty construction accessories that have the advantage of toughness and chemical resistance.
Processing Guidelines For Low-Density Polyethylene For Injection Molding
To maintain the same level of consistency in the quality comparable to the LDPE injection molding grade, the processors are to optimize the temperature, pressure, and cooling according to the resin data sheets and mold design. The ductile material of LDPE needs concern regarding shrinkage, venting, and packing to hold size and surface finish.
General processing procedures:
- Barrel/melt temperature: Adjust the settings to obtain approximately 160-220 °C, higher on thick parts or with low flow grades.
- Injection rate and pressure: Moderate-high rate and pressure are used to inject the tools with thin walls and multi-cavities without excessive shear, which results in burn marks.
- Mold temperature and cooling: Keep the mold temperature in 10-60 °C and evenly distribute the cooling circuits to regulate the warpage and the time taken.
- Drying: LDPE is not very hygroscopic, but the pellets are to be kept dry and clean; in demanding parts, a very gentle pre-drying can be beneficial.
Close connection with an established LDPE injection moulding resin supplier, such as Shobeir Shimi, assists in changing these parameters to real part geometry, wall thickness, and preferred cycle time.
