Five‑Layer Extrusion Tube Making Machine

Features

Plastic materials have their own inherent properties. In a co‑extrusion system, multiple materials are used and combined as required, giving multi‑layer tubes composite characteristics that cannot be achieved with single‑layer tubes.

1.Smooth surface texture and appearance (Application: EVOH / Adhesive / PE)

2.Wide range of color combinations (Application: PE + pearlescent / PE + color masterbatch)

3.Excellent air barrier properties (Application: PE / Adhesive / EVOH / Adhesive / PE)

4.Surface scratch resistance and reduced dust adhesion (Application: LDPE / LDPE / LLDPE)

Multi‑layer co‑extrusion is used in pesticide containers, toothpaste tubes, transparent windows, multi‑color designs, and cosmetics requiring a long shelf life.
