There is high range of crystalline nature in BOPP films as the surface of these films is nonpolar.
The performance of this film in the printing is poor and has poor relativity as to ink because of low surface energy.
In spite of few drawbacks BOPP films have become the latest buzzword in the packaging arena and they are in the good books of both the manufacturers and the end users.
During your journey through educating yourself about the different types of flexible packaging films, you have decided that you want to use shrink film or biaxially oriented polypropylene overwrap film (also known as BOPP).
However, you are not sure what the difference between these two types of flexible packaging films is. You want to understand the difference between these films so that you can choose the proper film for your product packaging needs.
But, you have not been able to find a comparison for these two films, and it's been hard to get the answers you are looking for.
Luckily, today, you have come to the Industrial Packaging blog.
In this article, we will compare BOPP film and shrink film. After reading this article, you will be able to choose the appropriate film for your packaging needs.
Shrink film (also known as shrink wrap) is a type of flexible packaging film used to package food, board games, and many other consumer goods. It is most commonly made from polyethylene, polyvinyl chloride, or polyolefin. Shrink film is ubiquitous on countless packaging lines worldwide.
When using shrink film, the product being packaged is put into a sleeve made from shrink film and sealed on both sides with a machine called a sealer. From there, the product is moved via a conveyor belt into another device called a heat tunnel. As the name would suggest, the inside of the tunnel is heated.
As the product moves through the heat tunnel, the heat produced by the machine causes the shrink film to shrink uniformly around the product. From there, the product moves through the rest of the packaging line and gets packed for shipping.

Biaxially oriented polypropylene (also known as BOPP) film is a kind of flexible packaging film. Unlike shrink film, BOPP is not heated and shrunk in a heat tunnel but used as an overwrap film to package your products. An overwrap film is applied by wrapping the film over the product or over another form of packaging containing the product.
BOPP films are generally used for food packaging. However, they are also fast replacing cellophane for applications, including snacks and cigarette packaging. For the most part, this is due to BOPP's superior capabilities and lower cost.
Biaxially oriented polypropylene film features increased barrier properties to oxygen and water vapor. Resistance to impact and flexcrack are also better with BOPP when compared to polypropylene shrink film.
