Process of fusion-bonding plastic film and drug bag

A process of manufacturing a drug bag, comprising:

• sealing a front-side plastic film and a back-side plastic film such that a drug bag body having a compartment is formed;
• placing a portion of a port member between the front-side plastic film and the back-side plastic film such that the compartment communicates with outside of the drug bag body through the port member;
• disposing a heat generation element on a front surface of the front-side plastic film;
• pressing a press member toward the heat generation element, the front-side plastic film and the port member;
• irradiating infrared laser to the heat generation element through the press member during the pressing such that the heat generation element generates heat by absorbing the infrared laser transmitted through the press member;
• and
• fusion-bonding the portion of the port member to the front-side plastic film.

A process of manufacturing a drug bag, comprising:

• sealing a front-side plastic film and a back-side plastic film such that a drug bag body having a plurality of the compartments is formed, the plurality of compartments comprising a first compartment and a second compartment separated by a weak seal portion;
• placing a plastic film for a handle on a front surface of the front-side plastic film;
• disposing a heat generation element on a front surface of the plastic film for the handle;
• pressing a press member toward the heat generation element, the plastic film for the handle and the front-side plastic film;
• irradiating infrared laser to the heat generation element through the press member during the pressing such that the heat generation element generates heat by absorbing infrared laser transmitted through the press member;
• and
• fusion-bonding the plastic film for the handle of the front-side plastic film,
• wherein the weak seal portion is unsealable by pulling the plastic film for the handle away from the front-side plastic film of the drug bag body.

A process of manufacturing a drug bag, comprising:

• sealing a first film and a second film such that a drug bag body having a compartment is formed;
• placing a portion of a port member between the first film and the second film such that the compartment communicates with outside of the drug bag body through the port member;
• disposing a heat generation element on an outer surface of the first film;
• pressing a press member toward the heat generation element, the first film and the port member;
• irradiating infrared laser to the heat generation element through the press member during the pressing such that the heat generation element generates heat by absorbing the infrared laser transmitted through the press member;
• and
• fusion-bonding the portion of the port member to the first film.

A process of manufacturing a drug bag comprises:

• sealing a first film and a second film such that a drug bag body having a plurality of compartments is formed, the plurality of compartments comprising a first compartment and a second compartment separated by a weak seal portion;
• placing a film for a handle on an outer surface of the first film;
• disposing a heat generation element on an outer surface of the film for the handle;
• pressing a press member toward the heat generation element, the film for the handle and the first film;
• irradiating infrared laser to the heat generation element through the press member during the pressing such that the heat generation element generates heat by absorbing the infrared laser transmitted through the press member;
• and
• fusion-bonding the film for the handle of the first film.

A drug bag comprising:

• two plastic films sealed to each other such that a drug bag body having a compartment is formed;
• a port member sandwiched and fusion-bonded between the two plastic films, the port member being provided to allow the compartment to communicate with outside of the drug bag body;
• and
• heat generation elements configured to generate heat by absorbing infrared laser and disposed on outer surfaces of the two plastic films such that the port member is fusion-bonded between the two plastic films.

A drug bag comprising:

• two plastic films sealed to each other such that a drug bag body having a plurality of compartments is formed, the plurality of compartments being separated by a weak seal portion;
• plastic films for handles fusion-bonded to outer surfaces of the two plastic films, respectively, the two plastic films for handles being provided such that the weak seal portion is unsealable by pulling the handles;
• and
• heat generation elements configured to generate heat by absorbing infrared laser and disposed on respective outer surfaces of the plastic films for the handles such that the plastic films for the handles are fusion-bonded to the two plastic films, respectively.
