cosmetic tube production process

cosmetic plastic tube and laminated tube

Extruded pipe is made of PE plastic after melting, in the way of sub-multilayer extrusion + hollow blowing process. It is manufactured into a continuous and complete plastic pipe without seams (according to the requirement of airtightness, some of them will add EVOH layer).
Laminated tubes are made of different PE plastics melted and blown to obtain multi-layer film, then extruded and laminated with aluminium metal film to form a single film, which is then welded to form a continuous, but with seams, tube body.
The surface of the extruded pipe is complete and continuous, while the surface of the laminated pipe has a longitudinal fine seam.
