Manufacturing Process Polyolefin Shrink Film

Polyolefin shrink film is a versatile packaging material widely used in various industries due to its excellent shrinkability, transparency, and durability. We are polyolefin heat shrinkable film manufacturer, and introduce how to produce this important packaging material. The manufacturing process of polyolefin shrink film involves several stages.

Step 1: Raw Materials ~ Polyolefin Shrink Film Manufacturing

Firstly, the raw materials, typically polyethylene or polypropylene resins, are mixed with additives such as slip agents, anti-block agents, and UV stabilizers. These additives enhance the film’s properties and processing characteristics.

Step 2: Film Coextrusion ~ Manufacturing Polyolefin Film

Next, the resin mixture is melted in an extruder and formed into a flat sheet through a die. The sheet is then cooled and solidified, forming a thin film.

Step 3: Biaxial Orientation ~ Manufacturing Process

After solidification, the film is stretched biaxially using a tenter frame or a blown film process. Biaxial stretching improves the film’s tensile strength, clarity, and shrinkability.

Step 4: Jumbo Rolls ~ Polyolefin POF Shrink Film

Once stretched, the film undergoes a heat-setting process to stabilize its dimensions. This step ensures that the film retains its shape and size when subjected to heat during the shrink process.

Step 5: Film Slitting ~ Production Process Polyolefin Packaging Material

Finally, the film is wound into rolls, ready for use. Throughout the manufacturing process, quality control measures are implemented to ensure consistent thickness, clarity, and strength of the film.
