Abstract

A standup bag for granular products or the like and a method of manufacturing the bag. The standup bag is manufactured from an extruded heat sealable material and includes both an integral handle and a perforation to facilitate opening and pouring out the contents of the bag.

Claims (7)

1. A method for manufacturing a bag from a non-laminated extruded heat sealable film, comprising the step of continuously heat sealing the film in predetermined areas without using a cooling medium for controlling temperature of the film and wherein the heat sealable film has an inside layer and an outer layer, the inside layer having a lower seal initiation point and a higher hot track than the outer layer.
2. A bag made by the method of claim 1.
3. A method for manufacturing a bag from a single piece of non-laminated extruded heat sealable film, comprising the step of continuously heat sealing the film in predetermined areas without using a cooling medium for controlling temperature of the film.
4. A bag made by the method of claim 3.
5. A bag manufactured from a non-laminated extruded heat sealable film, wherein the film is continuously heat sealed in predetermined areas without using a cooling medium for controlling temperature of the film.
6. A bag manufactured from a non-laminated coextruded heat sealable film, wherein the film is continuously heat sealed in predetermined areas without using a cooling medium for controlling temperature of the film and the film has an inside layer and an outer layer, the inside layer having a lower seal initiation point and a higher hot tack than the outer layer.
7. The bag according to claim 6, further comprising an overcoating over all areas of the bag that contact heat sealing jaws.
