ABSTRACT:
There is disclosed a modified method of preparing a blown polyethylene film made from a blend of major proportion of a polyethylene resin, e.g., LLDPE, a minor proportion of a second polymeric resin, e.g., polystyrene, and at least one additive, e.g., a colorant. The additive or additives are mixed with the second polymeric resin and the resulting mixture is then blended with the polyethylene resin, thereby reducing the number of process steps. Also disclosed is a method of monitoring and/or controlling the second polymeric resin content in the film made with known proportions of a colorant and the second polymeric resin by measuring the light transmission of the film.
