What is OPP Packaging? Production Process and Usage Areas
The question of what OPP packaging is carries great importance for businesses seeking durable and transparent solutions in the packaging world. Manufacturers obtain this plastic film by stretching polypropylene raw material in a single direction using specialized techniques. Thanks to its high transparency and durability, this material has a highly widespread usage area in the packaging sector. Especially companies in the food sector prefer these films to pack their products in a hygienic and aesthetic manner. Thanks to their lightweight structure and high strength, these packages successfully protect food products from external factors.
Food Contact and Safety Standards
When experts use the right raw materials, films achieve full compliance with food contact. With their odorless and tasteless structure, these films never affect the natural properties of food. Teams subject OPP packaging to these critical tests within the framework of international regulations:
Migration Tests: They measure the transfer amount of packaging components into food.
Heavy Metal Analyses: They prove that the product is purified from toxic substances.
These tests guarantee that substances capable of migrating from packaging to food remain within safe limits. Thus, consumers safely consume foods protected by this packaging.
OPP Packaging Production Stages
The production process starts with the processing of the polymer and continues with meticulous steps:
Raw Material and Extrusion
In the first stage, manufacturers select food-certified polypropylene granules. Then, extrusion machines melt these granules at high temperatures to transform them into a thin film layer.
Orientation and Surface Treatment
During the orientation process, machines stretch the film in a single direction. This process adds high durability and crystal-clear transparency to the film. Afterward, the applied Corona treatment makes the film surface ready for printing and lamination processes.
Printing and Final Preparation
Design teams print the packages using flexography or rotogravure techniques. When necessary, they perform lamination with different layers to extend the product’s shelf life. In the final stage, machines slit the reels into desired dimensions, making them ready for shipment.
Usage Areas and Advantages
Professionals researching what OPP packaging is will see that this material plays an active role in packaging biscuits, chocolate, nuts, and pasta. These packaging solutions, compliant with international standards, both ensure food safety and protect your brand value.
