Read： 1430 Time：17months ago Source：Transform the World with Simplicity

With the continuous improvement of industrial production, high-performance materials and efficient production methods are increasingly needed. OPP material, highlighting its necessity and superiority in the current environment. So, with OPP as the protagonist, let's first discuss what material it is?

1. What material is OPP?

OPP's full name is polypropylene film, is a plastic film made of polypropylene products, with light weight, high strength, water resistance, oil resistance, high temperature resistance and other characteristics, commonly used in food, medical, pharmaceutical packaging and packaging printing and other fields.

2. Physical Properties of OPP

The physical properties of OPP materials show outstanding performance among many materials:

Heat resistance: OPP films can withstand temperatures below 75 ℃ and can withstand excellent heat sealing.

oxygen barrier: OPP film sealing strong, can protect the wrapped items from external oxygen pollution caused by deterioration.

moisture resistance: OPP film has excellent moisture resistance and can maintain the dryness and freshness of wrapped items.

oil resistance: OPP film can well resist various types of grease and other harmful substances, can guarantee the quality of the package.

3. Application of OPP

OPP film is widely used and has gradually become one of the main materials in the packaging manufacturing industry. The following are its main application areas:

food packaging: OPP material has good transparency and strong moisture resistance, and is usually used for food packaging such as biscuits, potato chips, cakes and ice cream.

drug packaging: Because the OPP film is water-resistant, oil-resistant, and corrosion-resistant, drug manufacturers usually choose OPP packaging to preserve drugs.

electronic product packaging: OPP film has excellent insulation performance and is often used in the outer packaging of electronic products such as smart phones and tablet computers.

4. Comparison between OPP and other materials

The physical properties of OPP materials also have many advantages compared with other materials, as follows:

PP materials: OPP has higher permeability to light and longer service life than PP.

PE material: OPP material is more stable and durable than PE in oxidation resistance.

PVC material: OPP material is more environmentally friendly than PVC, with higher durability and mechanical strength.

To sum up, OPP, as one of the important materials in the current production and manufacturing, has attracted wide attention from manufacturers for a long time. Due to the superiority of its physical properties, OPP has gradually replaced traditional packaging materials and has become an essential material in modern manufacturing.
