ethylene
Low-density polyethylene does exhibit a glass transition at around 150K.
Low-density polyethylene (LDPE), used for plastic storage bags, melts at about 110 degrees Celsius. High-density polyethylene (HDPE), used for supermarket plastic bags, melts at 130 degrees Celsius.
LDPE (low density polyethylene) is used for making plastic bags because it is appropriate and HDPE (High density.....) is not.
If you think to recycling codes: - 01 is for polyethylene terephtalate (PET) - 02 is for high density polyethylene (HDPE) - 03 is for polyvinyl chloride (PVC) - 04 is for low density polyethylene (LDPE) - 05is for polypropylene (PP)

Most of plastic bags are made of Polyethylene. It could be made of High Density Polyethylene (HDPE) or Low Density Polyethylene (LDPE) or a combination of both in addition to Linear Low Density Polyethylene (LLDPE).

Plastic bottles are made from a variety of plastics. These include low density polyethylene, high density polyethylene, polyvinyl chloride and polypropylene.
LDPE is Low Density PolyEthylene.HDPE is High Density PolyEthylene.
Low-density polyethylene does exhibit a glass transition at around 150K.
