LLDPE granule for blow molding film

LLDPE (Linear Low-Density Polyethylene) granules are widely used in blow molding applications for producing films due to their beneficial properties. Here are some details about LLDPE granules specifically designed for blow molding film production:

Key Features of LLDPE for Blow Molding Film

High Strength: LLDPE offers excellent tensile strength, making the resulting film tough and durable while allowing it to withstand impact and stretching.
Flexibility and Elasticity: Films made with LLDPE are more flexible compared to HDPE films, which allows for greater resistance to punctures and tears.
Transparency: LLDPE films typically have good clarity and gloss, making them ideal for packaging applications where visibility is important.
Good Heat Sealing Properties: LLDPE has a relatively low melting point, enabling effective sealing at lower temperatures, which is ideal for high-speed packaging operations.
Compatibility with Additives: LLDPE granules can be mixed with various additives like UV stabilizers, anti-block agents, and slip agents to enhance film properties according to specific requirements.

Common Applications

LLDPE granules for blow molding are primarily used in:

Packaging Films: Used for food packaging, agricultural films, stretch wraps, and liners.
Industrial Films: Covers for goods in storage or transport.
Agricultural Films: For greenhouse covers, silage films, and mulch films due to their flexibility and durability.

Grades and Selection

LLDPE granules for blow molding are available in different grades, with each grade tailored for specific properties like:

Thickness requirements: Thinner films require granules with specific flow characteristics.
Optical properties: Certain grades are chosen to achieve greater transparency and gloss.
Processing requirements: Grades vary based on compatibility with different blow molding machinery.

Processing of LLDPE granule for blow molding film

The blow molding process for LLDPE typically includes the following steps:

Extrusion: LLDPE granules are melted and extruded through a die, forming a tubular shape.
Blowing: The tube is inflated with air, stretching it to form a thin, even film.
Cooling: The inflated film is cooled and then wound onto rolls for further processing or distribution.

When choosing LLDPE granules for blow molding film, manufacturers often work with suppliers to select the right grade and blend to meet their specific needs, including factors like tear strength, puncture resistance, and flexibility.
