The ACC reports that LDPE has an excellent resistance to acids, bases and vegetable oils. Its toughness, flexibility and relative transparency make it good for packaging applications requiring heat-sealing.

Most areas offer recycling for products made with LDPE and linear low-density polyethylene (LLDPE), which also features a recycling number 4. Like all other types of plastic, LDPE can take hundreds of years to decompose in the landfill, so products that are made exclusively of LDPE should be recycled if possible. Some areas don’t offer recycling for plastic bags made from LDPE, but these can be reused instead.

LDPE is used to make many thin, flexible products like plastic bags for dry-cleaning, newspapers, bread, frozen foods, fresh produce and garbage. Most shrink-wrap and stretch film is also made out of LDPE, as well as coatings for paper milk cartons and disposable beverage cups. Manufacturers also use LDPE to create thin container lids, squeezable bottles and some toys.

 

Polyproplyene

A polypropylene bag is high clarity and crystal clear in order to enhance the image of whatever product is inside. This PP bag offers a highly protective barrier against both moisture and vapors. These poly bags delay evaporation and dehydration to preserve the freshness and taste of packaged foods. Generally, PP plastics are stronger, clearer, and more expensive than their PE plastic counterparts.

 Polypropylene bags are great for the following industries — food, electronics and electronics manufacturing, hospitals, agriculture, and more.

  • More resistant to chemicals, high temperatures, and scratches
  • Crystal clear for great product presentation
  • Stiff and hard plastic
  • Rough surface has the potential to produce scratches
  • Outstanding vapor and moisture barrier
  • Meets FDA and USDA specifications
  • Difficult to break, but not very flexible

Low Density Polyethylene

Low Density Polyethylene LDPE
Use LDPE pipe as part of a garden irrigation system when distributing water to pots, containers, vineyards, orchards, garden beds and borders or around the perimeter of a greenhouse. To maximise water flow efficiency, the pipe must be uncoiled correctly on a warm, sunny day as this makes the pipe easier to handle and less likely to kink. Unravel the pipe in a straight line weighing each end down with a brick and leave for one hour.
