What are the disadvantages of Biaxially Oriented Polypropylene?

You might be surprised to learn that there are in fact downsides to Biaxially Oriented Polypropylene.

A few of the disadvantages that this film propose is that the sealing is poor. There is a high range of crystalline nature in Biaxially Oriented Polypropylene film which means when the plastic crystals, it alters the aesthetics making it hazy, and also can alter the structure of it. This plastic film has low surface energy, which means even though it is used for printing on, it doesn’t hold ink very well, making the print result poor quality.

If you don’t heat seal Biaxially Oriented Polypropylene, then it becomes much more static, which isn’t ideal. The reason for this is because when plastic components become charged, pieces of dirt including hair, dust and debris will be drawn to the charge. Since plastics are insulators, they are poor conductors of electricity. These particles that are drawn to the charge can cause problems in certain situations such as medical applications and electronics. These particles are not easily removed because of the static charge, and no washing or blowing on the parts will dislodge them, which is why it is important to have preventative measures in place.
