摘要： The invention provides a method of producing material for use in packaging, and apparatus for carrying out that method, which includes the steps of providing first and second continuous webs of sheet material each having longitudinally on a face thereof a respective one of a pair of elongated male and female closure formations, moving said first and second webs along closing paths with the respective formations presented towards each other, applying pressure to the male and female formations across the plane of separation of the webs so as to cause them to become interengaged and thereby define one of a first pair of opposed boundaries of the receptacle, said webs being initially, simultaneously, or subsequently joined longitudinally at a position spaced from said formations so as to define the other of said first pair of opposed boundaries.
