Abstract
A packaging system (10) for tube stock continuous film media (20). The system forms a bag, fills the bag with product, and seals the bag. A floating platen (30) is used to separate the two layers of the tube stock continuous film media during processing. The system is suitable with a wide variety of different types of media, and forms an aesthetically pleasing package.
Claims33
A packaging system for forming, filling and sealing a bag formed from an associated continuous film media having a generally continuous first layer portion and a generally continuous second layer portion, said first and second layer portions being sealed together at the peripheral side edges thereof to form a tube, the packaging system comprising:
- media advancement means adapted for advancing the associated media through a processing path;
- first sealing means adapted for forming a first seal between said first and second layer portions in a direction transverse to the peripheral side edges, said first seal defining a bottom of the bag;
- isolation means adapted for isolating the first layer portion from the second layer portion;
- first cutting means adapted for cutting the first layer portion in a direction transverse to the peripheral side edges while the first layer portion is isolated from the second layer portion by the isolation means;
- blower means adapted for directing a gas into the bag, to open the bag for insertion of a product therein;
- second sealing means adapted for forming a second seal between said first and second layer portions in a direction transverse to the peripheral side edges, said second seal defining a top of the bag;
- second cutting means adapted for cutting at least the second layer portion in a direction transverse to the peripheral side edges to separate the bag from the associated media, wherein said second cutting means is located between said first and second sealing means.
A method for forming, filling and sealing a bag formed from an associated continuous film media having a generally continuous first layer portion and a generally continuous second layer portion, said first and second layer portions adaptable to form a tube, the method comprising the steps of:
- advancing the associated media through a processing path;
- forming a first seal between said first and second layer portions in a direction transverse to the peripheral side edges, said first seal defining a bottom of the bag;
- isolating the first layer portion from the second layer portion;
- cutting the first layer portion in a direction transverse to the peripheral side edges while the first layer portion is isolated from the second layer portion;
- blowing a gas into the bag to open the bag for insertion of a product therein;
- forming a second seal between said first and second layer portions in a direction transverse to the peripheral side edges, said second seal defining a top of the bag;
- and
- cutting at least the second layer portion between a first seal and a second seal, in a direction transverse to the peripheral side edges from the associated media to separate the bag from the associated media.
A packaging system for forming, filling and sealing a bag formed from an associated continuous film media having a generally continuous first layer portion and a generally continuous second layer portion, the packaging system comprising:
- media advancement means for advancing the associated media through a processing path;
- isolation means adapted for isolating the first layer portion from the second layer portion;
- first cutting means for cutting the first layer portion in a direction transverse to the peripheral side edges while the first layer portion is isolated from the second layer portion by the isolation means;
- dispensing means for dispensing a product into the bag;
- first sealing means for forming a first seal between said first and second layer portions in a direction transverse to the peripheral side edges, said first seal defining a bottom portion of a first bag;
- second sealing means for forming a second seal between said first and second layer portions in a direction transverse to the peripheral side edges, said second seal defining a top portion of a second bag;
- second cutting means for cutting at least the second layer portion in a direction transverse to the peripheral side edges to separate the bottom portion of the first bag from the top portion of the second bag.
