Abstract
A packing laminate for the manufacture of packing containers for edible oil must have an oil-resistant inner layer which is not affected by the oil, even during prolonged storage periods. A packing laminate meeting this condition has an extruded inner layer of two types of plastics mixed with one another, namely LLDPE and LDPE.
