LDPE plastics, or low-density polyethene, are soft and flexible polymers with unique properties. Compared to High-Density Polyethylene (HDPE), LDPE has a lower density, strength, and temperature resistance. However, LDPE compensates with excellent processability and desirable characteristics.
Manufactured through free radical polymerisation, LDPE plastics have a higher degree of short and long-side-chain branching. This structure is achieved at high bar pressure (1000-3000) and a relatively low-temperature range of 80ºC to 300°C. The resulting material exhibits advantages such as high impact strength at low temperatures, chemical resistance, good weatherability, excellent electrical insulation, low water absorption, compliance with FDA regulations, and transparency in thin foil film.
Versatile and Durable Packaging
LDPE plastic bags offer exceptional versatility for a wide range of products. Whether used for groceries, clothing, or hardware, LDPE bags are designed to withstand rigorous handling and transportation. They resist tearing, punctures, and moisture, ensuring secure protection throughout the supply chain.
In addition to durability, LDPE plastic bags are lightweight and flexible, facilitating easy handling, transportation, and efficient storage. Their convenience and practicality make them an optimal choice for various applications. These bags are also recyclable, reducing waste and minimising environmental impact.
FDA-Approved Plastic Packaging
LDPE plastic bags are a trusted option for food packaging as they are FDA-approved for direct contact with food. They meet stringent quality and hygiene standards, ensuring product freshness and safety preservation.
They are categorised as the number 4 plastic LDPE plastic bags that find primary use in film applications. LDPE is the preferred material for reliable and sustainable packaging solutions, from food packaging to shrink wrap and stretch film. Its physical properties provide excellent resistance to various chemicals, including alcohols, dilute alkalis and acids while protecting against moisture, dust, dirt, oil, and grease.
- Lightweight, low-cost and weatherproof
- Excellent Insulator: Unlike HDPE, this plastic material incorporates unique insulation properties, which makes it ideal for protecting electronic equipment without causing electric sparks that might potentially result in damage to electronics.
- Highly Flexible and Transparent: The high flexibility of the material makes it easy to process and mould into various shapes and sizes to meet different applications.
- Recyclable: Compared to most other plastic materials, decomposing requires more than 100 years. Hence, LDPE-made products should be recycled and reused whenever possible. Recycled LDPE can form products such as shipping envelopes, trashcans, compost bins, garbage can liners, floor tile, furniture, etc.
