#4 LDPE is commonly used in plastic bags, garbage bags, squeeze bottles, chip packets, plastic wrap and black irrigation tubes. Quite often it is made from soft, flexible, waxy surface translucent fibres and withstands solvents.
To avoid landfill, you can collect your soft plastics and dispose of them at your local Coles or Woolworths where Australian owned recycling and manufacturing partners Replas, Close the Loop and Plastic Forests utilise the soft plastics and turn them into a range of recycled products.
