From a Snap-on Lid to a Playground Slide

LDPE TriangThis is the low density version of Polyethylene. It has less hardness, stiffness and strength compared to HDPE, but more ductile. This plastic has an optimal density, hard wearing construct and long functional life. Its opacity means only thin foils can be transparent. LDPE is widely used for manufacturing various containers, dispensing bottles, wash bottles, tubing, and various molded laboratory equipment. Its most common use is in plastic bags.

Other Uses:

Trays and general purpose containers
Corrosion-resistant work surfaces
Weldable and machinable parts
Flexible components
Very soft and pliable parts such as snap-on lids and six pack rings.

Packaging for computer hardware, such as hard disk drives, screen cards, and optical disc drives
Children’s Activity Areas including Playground slides
Plastic wraps

The versatility of LDPE makes it ideal for greenhouses and gardening tunnels, silage containers, electrical cable insulation and semiconductive layers Coax and HFFR (halogen-free flame retardant) cables. Low Density Polyethylene membranes are extensively used for prevention of liquid contamination. They act as perfect liners to prevent contaminations from entering groundwater sources, as well as prevent seepage loss.

The life span of roads depends on various factors like the soil being prevented from sub-grade movement. This is achieved by using LDPE sheet and LDPE plastic sheet placed in such a way that the aggregate is permanently separated from finer soils below. This prevents the sub-grade to enter into the aggregate and at the same time, improves the underground drainage of roadways and pedestrian walkways.

Other Applications:

Agricultural purposes
Lining of canals, reservoirs and ponds
Lining of industrial effluent plants
Tunnels and trenches and roads Packaging, water-proofing for terraced gardens
Emergency shelter houses during natural disasters and conflict Fumigation covers and cover tops Tarpaulins and cap covers
Aprons & runways in airports
