Additives: UV stabilizers are added to prevent degradation from sunlight (essential for outdoor use), along with color masterbatches and anti-oxidants.

The Die Head: The molten plastic is forced through a specialized rotating die. The relative motion of the die parts creates the intersecting strands that form the initial "mesh" structure.

Quenching: As the hot plastic mesh emerges, it is immediately cooled in a water bath or over a chilled mandrel. This solidifies the plastic into a "pre-stretched" tube or sheet.

3. Molecular Orientation (The Stretching Phase)

Machine Direction (MD) Stretching: The netting passes through a series of rollers. Each successive roller rotates faster than the previous one, pulling the mesh lengthwise.

• Transverse Direction (TD) Stretching: For bi-axially oriented nets, the material is fed into a "tenter frame," where mechanical clips pull the edges of the net outward in a heated oven.

• Biaxial Orientation: When stretched in both directions, the netting gains high tensile strength and dimensional stability in both length and width.

4. Heat Setting and Annealing

• once stretched to the desired dimensions, the netting must be "set" to prevent it from shrinking back to its original size.

The final step prepares the netting for the end-user.

Trimming: The uneven edges of the net are trimmed off.

• Slitting: Large master rolls can be slit into narrower widths depending on the application (e.g., small rolls for meat packaging or wide rolls for crop protection).

• Winding: The finished netting is wound onto cardboard or plastic cores, inspected for quality, and packaged.
