Abstract
A packaging apparatus including a receptacle, a ram, a film dispensing assembly and first and second elongate members. The receptacle defines a central axis and has a dispensing end with first and second substantially linear and parallel opposed edges that define an axial limit of the dispensing end. The plastic film material forms a film tube about the receptacle. The first and second elongate members are substantially parallel with the first and second edges. In operation, the ram is extended to eject the batch of material through the dispensing end into the film tube. Retracting the ram forms a partial vacuum within the film tube between the batch of material and the ram. The first and second elongate members compressively engage the film tube between the batch of material and the dispensing end and thereby form folded flaps in the film tube. A method of packaging is also disclosed.
