Inside the Manufacturing Process of POF Shrink Film You Use Every Day

pof shrink film manufacturer is a term that points to a detailed and technically structured process, where packaging films are produced for use in everything from food wrap to cosmetic bundling. Yet many people using these films daily have little idea how they are made.

The process starts with resin selection. Granulated polyolefin resins are chosen for their ability to form strong, flexible films. At jtpackage, we carefully control material sourcing to ensure stable film performance during sealing and shrinking.

Once selected, the resins go through extrusion, where they are melted and blown into thin sheets. These sheets are then rapidly cooled and flattened in a controlled environment to preserve clarity and consistency. This is a critical stage, as it determines the strength and smoothness of the film.

Afterward, the film enters the irradiation and crosslinking phase. This step improves heat resistance and enhances tensile strength. It also ensures that the film performs well under various packaging machine conditions. At jtpackage, this phase is monitored continuously to align with client usage needs.

Next, the film is slit into rolls of varying sizes depending on customer specifications. Labels are applied for traceability, and each batch is quality-checked before shipment. From start to finish, jtpackage emphasizes process clarity and product reliability.

By understanding how pof shrink film is manufactured, buyers and users can make better decisions about product selection and supplier engagement.
