LDPE (Low‑Density Polyethylene)

LDPE is soft, highly transparent and ductile, with wax‑like hand‑feel and good elasticity. Its density ranges from 0.91‑0.925 g/cm³. It features excellent low‑temperature flexibility, good chemical resistance against acid‑alkali corrosion and outstanding electrical‑insulation performance. Nevertheless, it has relatively low mechanical strength and poor heat resistance, with continuous‑service temperature generally below 80 °C. Its oxygen‑barrier property is limited, and it is susceptible to ageing under ultraviolet radiation and thermal conditions.

Main Applications

Film & packaging: Mainly used for various packaging films including food cling wraps, shopping bags and garment‑packaging bags. In agriculture, it is processed into mulch films and vegetable greenhouse films. It also acts as base material for composite flexible packaging, serving as inner liners for milk and beverage packages.

Injection molding: Small daily‑use plastic articles such as bottle‑cap liners, toys, sealing containers and household plastic parts.

Extrusion coating: Waterproof inner coating for paper cups and cartons (e.g. milk cartons and juice cartons), as well as heat‑seal coating for aluminium foil and paper to deliver moisture‑proof and heat‑sealable performance.

Cable & tubing: Insulating sheaths for wires and cables, and various flexible hoses including medical tubes, laboratory conduits and squeeze bottles.

Please specify your additional requirements: gloss level, melt‑flow index, ash content, environmental compliance, surface pitting and other physical‑property parameters.

MOQ: 1 ton upon successful sample testing. After‑sales: return and replacement for quality‑related defects.
