Application:
The general practical life applications of co-extruded films are: pure milk bags, express bags, and metal protective films.
For example, a kind of co-extrusion film: black and white film, used to make express bags or milk bags, because the express bags contain hard objects or various factors cause the bags to be easily broken, so ordinary PE film cannot be used, and co-extrusion is required. Film; Coincidentally, food bags (eg: pure milk bags) are also required to meet food standards and not be easily broken, so co-extruded films must be used. The black and white film is a double-layer co-extrusion film. When the plastic is extruded, there are two heads that extrude the black PE film and the white PE film at the same time. The film is still in a semi-liquid state. to glue.
The main characteristics of the co-extruded film: good tensile properties, good surface brightness, in line with many standards of adhesive film, food film.
The origin is mainly in the south and Hebei.
