Polymer Type

Thermoplastic

Advantages

Good low temperature toughness.  Very good barrier properties (better than Polyethylene’s).  Transparent.  Good oil and solvent resistance   little tendency to solvent stress cracking.  Better puncture resistance than LDPE film.

Disadvantages

Poor resistance to acids. Similar (poor)weathering characteristics as Polyethylene.  Poor creep resistance.
