Abstract
In one method, a piece of nonwoven PET or PP fabric is formed into a tote bag using a bag forming device. Seams of the tote bag are ultrasonically welded using an ultrasonic bag welding device. The ultrasonic bag welding device includes at least one sonotrode. In another method, BOPP film is received and a full-color graphic is printed on the BOPP film for each tote bag using a printer. The printed BOPP film is received from the printer and nonwoven PP or PET fabric is received from a roll of nonwoven PP or PET fabric using a laminator. The printed BOPP film is laminated to the nonwoven PP or PET fabric. The printed BOPP film laminated to nonwoven PP or PET fabric is received from the laminator and a finished version of each tote bag is produced using an ultrasonic bag welding device.
Claims8
