oxygen and carbon dioxide. It is a good barrier to water vapour.
When thermoformed it is suitable for use at temperatures up
to 110(C, therefore it is suitable for use in the microwave
oven. It is often micro-perforated, in this instance it is widely
used to store bakery/confectionery products. It is easy to recycle.
It has poor heat sealing characteristics. PP is also used to
make closures. It is a very versatile packaging material.
