With the continuous development of society, people have higher and higher requirements for packaging materials. Therefore, choosing the right packaging material is very important. OPP is one of the most widely used packaging materials.

So, what is OPP? In fact, OPP is the abbreviation of oriented polypropylene (polypropylene oriented film). It is a plastic film made of polypropylene, which is characterized by smoothness, transparency, good toughness, folding resistance, etc.

OPP has the following characteristics:

first, good smoothness. Because of its smooth surface, it can print words and patterns well. Because its surface is smooth, so the friction coefficient is small, suitable as a packaging material.

second, high transparency. The advantage of high transparency is that it is convenient for consumers to observe the packaged items, and it can also increase the aesthetics of the packaging.

third, good toughness. Since OPP is a polymer material, its toughness is excellent. Especially in the application of packaging, OPP can ensure the stability of packaging products.

fourth, resistant to folding. Since OPP is a lightweight film, it does not crease even in smaller radius packages.

in addition to the above characteristics, OPP also has the following advantages:

1.OPP material production is larger, developers on its performance and production process also has a very detailed study, can be mass production, reduce production costs.

2.OPP material is not afraid of moisture, moisture absorption strength is also low, not easily affected by humidity and moisture, extending the shelf life of the product.

3.OPP material cutting and production process is simple, very easy to process and produce.

So, what are the application areas of OPP materials? At present, the most commonly used application area of OPP is the packaging industry. Such as food, cosmetics, medicine, home and other fields. OPP bags, OPP printing packaging, OPP slice packaging, etc. are common applications.

So, what are the applications of OPP in our lives? Let's learn about it.

OPP is widely used in the food packaging industry. For example, candy packaging, biscuit packaging, spicy snack packaging, etc. all use OPP bags. The use of OPP bags in food packaging is becoming more and more common, because it can protect the items in the package from moisture, and it can also show the items inside the package, allowing consumers to have a more intuitive understanding of the quality of the product.

In addition, OPP is also widely used in pharmaceutical packaging, household packaging, cosmetic packaging, etc.

OPP, as an excellent packaging material, has a wide range of applications in our lives. Its characteristics and application in different fields provide us with a lot of convenience. It is believed that with the continuous development of technology, the performance of OPP will be more excellent and the application field will be more extensive.
