Biaxial stretching of pvc film
News:biaxial stretching method, this method is not a separate processing method, instead, it is a secondary D-processing method that stretches the film processed by other methods along the vertical and horizontal directions after heating. Traditionally, the biaxial stretch film is named BO letters in front of the resin, for example, BOPP is PP biaxial stretch film, while the unidirectional stretch film is named O letters in front of the resin, for example, OPP is a PP unidirectional stretch film.
The production methods of biaxial stretching include: Tube film biaxial stretching method, suitable for extrusion blow molding film, commonly used in the production of HDPE tear film; The flat film successively biaxial stretching method is suitable for T-head method and calendering film, but is not suitable for processing LDPE, HDPE, PBT, PA6, PA66, PVA and other materials; Flat film simultaneous biaxial stretching method is suitable for T-head method and calendering film. All films can be processed by simultaneous biaxial stretching method. At present, the main products are BOPP, BOPA, BOPET, BOPS and other varieties.
The advantages of the two-way stretch film are high strength, good rigidity, good transparency, good barrier property, high surface gloss, smooth surface, stable size, uniform wall thickness, light weight, non-toxic and moisture-proof. wait, widely used in transparent packaging, high-grade packaging, barrier packaging, composite film substrates and various industrial films.
