A flexible bag is positioned in a rigid container, such as a fifty-five gallon drum, and the bag is filled through its spout with flowable product, such as tomato paste. The bag is then expanded in the container to be substantially rigid and thereby reduce film movement and resultant flex cracking.
A flexible bag is positioned in a rigid container, such as a fifty-five gallon drum, and the bag is filled through its spout with flowable product, such as tomato paste. The bag is then expanded in the container to be substantially rigid and thereby reduce film movement and resultant flex cracking. A lid is sealed onto the container and a vacuum drawn from between the bag and the container, to, in turn, expand the bag. Gas volume needs to be present in the bag before the vacuum is applied so that the gas in the bag can expand from the vacuum on its outside. Once expanded, the container can be shipped.

1. A method of reducing damage to a transportable flexible bag comprising:placing a flexible bag into a substantially rigid container, said container having a removable cover; introducing a flowable product into said flexible bag; sealing said flexible bag so as to preclude the egress of material therefrom; placing said cover onto said container, to, in turn, seal the container; creating a vacuum inside said container and outside said flexible bag after sealing of said flexible bag and sealing of said container so as to substantially fix said flexible bag in a substantially rigid configuration relative to said container; and maintaining said flexible bag in said substantially rigid configuration during transportation of said container. 2. A method according to claim 1, wherein maintaining said flexible bag in said substantially rigid configuration includes adhering said flexible bag to said cover during the creating of said vacuum inside said container and outside said flexible bag.3. A method according to claim 2, wherein the adhering of said flexible bag to said cover is preceded by applying an adhesive to an inside surface of said cover.4. A method according to claim 1, wherein the maintaining of said flexible bag in said substantially rigid configuration includes maintaining a vacuum inside said container of about twenty inches of mercury.5. A method according to claim 1, wherein a gas is introduced into said flexible bag prior to creating said vacuum inside said container.6. A method according to claim 1, wherein a gas is introduced into said flexible bag simultaneous to creating said vacuum inside said container.7. A method of substantially eliminating creases and folds in a bag during transport of said bag comprising:providing a flexible bag; placing said flexible bag in a container; introducing a flowable product into said flexible bag; sealing said flexible bag so as to preclude the egress of material therefrom; sealing said container; creating a vacuum on the inside of said container and outside of said flexible bag after sealing of said flexible bag and sealing of said container such that said flexible bag substantially abuts the container, to, in turn, become a skin on an inside surface of said container; maintaining said flexible bag as a skin on said inside surface of said container during transport such that said flexible bag substantially maintains abutment when said flowable product is caused to move during said transport. 8. A method according to claim 7, wherein the maintaining of said flexible bag as a skin on an inside surface of said container includes adhering said flexible bag on said inside surface.9. A method according to claim 8, wherein prior to the adhering of said flexible bag to said inside surface of said container includes applying an adhesive to said inside surface of said container.10. A method according to claim 7, wherein the maintaining of said flexible bag as a skin on an inside surface of said container includes the holding of a vacuum on the inside of said container and outside of said flexible bag.11. A method according to claim 10, wherein the maintaining of said flexible bag as a skin on an inside surface of said container, includes holding the vacuum at about twenty inches of mercury.12. A method according to claim 7, wherein a gas is introduced into said flexible bag prior to creating said vacuum inside said container.13. A method according to claim 7, wherein a gas is introduced into said flexible bag simultaneous to creating said vacuum inside said container.14. A method for increasing the avoidance of stress cracks in a transportable flexible bag comprising;providing a flexible bag; placing said flexible bag in a substantially rigid container; filling said flexible bag with a product; sealing said flexible bag so as to preclude the egress of material therefrom; covering said substantially rigid container; creating a vacuum on the inside of said substantially rigid container and on the outside of the flexible bag after sealing of said flexible bag and covering said substantially rigid container; and, locking said flexible bag against an internal surface of said substantially rigid container such that said flexible bag is substantially prevented from movement during transport thereof. 15. A method as set forth in claim 14, wherein a gas is introduced into said flexible bag at substantially the same time as applying a vacuum on the inside of said substantially rigid container.16. A method as set forth in claim 14, wherein a gas is introduced into said flexible bag prior to applying a vacuum on the inside of said substantially rigid container.17. A method as set forth in claim 14, wherein locking of said flexible bag against an internal surface of said substantially rigid container includes adhering said flexible bag to said internal surface.18. A method as set forth in claim 17, wherein prior to adhering said flexible bag to said internal surface of said substantially rigid container, an adhesive is applied to said internal surface of said substantially rigid container.19. A method as set forth in claim 14, wherein locking said flexible bag against an internal surface of said substantially rigid container includes drawing a vacuum of about twenty inches of mercury on said substantially rigid container.
