Abstract
In-mold labelled, blow-molded articles formed from high density polyethylene, the labels being formed from biaxially oriented polypropylene based films having a shrinkage of at least 4% in both the machine and transverse directions as measured by the OPMA shrink test in which the film is suspended in an oven at 130° C. for a period of 10 minutes. The use of films with the specified shrinkage enables blistering and “orange peel” effects to be avoided when the blow-molding is carried out.
