Domestic existing explained hereafter plastic tube, the most of use of barrier layer be EVOH, and this novel PVA(polyvinyl alcohol, polyvinyl alcohol) coat has the wet resistance of better resistance oxygen effect, and is and more convenient on the mode of production.When common EVOH co-extrusion PE film is produced, need outsourcing processing, need simultaneously large-scale multi-layer co-extruded line, working condition requires high, and this Novel PVA only needs to apply one deck PVA coating on former film PE, and is easy to process, produce drop into little.After the PE film applies the PVA coating, improved better after tested the wet effect of resistance oxygen resistance of plastic tube, and barriering effect is all higher than generic EVOH co-extrusion PE film.From the comparison of getting on of the price of bi-material, EVOH itself is expensive, its complex manufacturing, production cost are higher, and there is very large cost advantage in the application of this Novel PVA coat film, use the PVA coat film as barrier layer, not only better barriering effect can be reached, more cost can be effectively reduced.
Therefore, major advantage of the present invention is:
1, the barrier layer of Plastics in China composite soft tube generally uses EVOH co-extrusion film as barrier layer, and the Novel PVA coat film is gathered around than EVOH co-extrusion film and had higher barrier.
2, the general large-scale Multi-layer co-extrusion film-blowing equipment of barrier material EVOH co-extrusion film need of production of plastic composite hose, equipment requirement and difficulty of processing are higher, and the PVA coat film only need can reach requirement by coating one deck PVA on original base material, greatly reduces difficulty of processing.
3, there is larger cost advantage in the PVA coat film on the price of raw material own than EVOH co-extrusion film.
To sum up, the barrier of high-barrier composite soft tube of the present utility model is high, and barrier obtains General Promotion, and easy to process, and production cost is low, is suitable for large-scale promotion application.
In this specification, the utility model is described with reference to its specific embodiment.But, still can make various modifications and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
