Abstract
High speed case and carton sealing lines for packaging articles. The carton to be packaged, i.e., filled and sealed, having disposed thereon an adhesive comprising an energy-absorbing ingredient that is capable of absorbing and reflecting radiant energy. The automated packaging machine comprises a means to reactivate an adhesive to effect sealing.
Claims33
A packaging machine comprising a means for reactivating an adhesive present on a packaging substrate, said means comprising a radiant energy source having a peak wavelenth of from about 400 nm to about 100,000 nm.
A process of packaging an article by forming, filling and sealing a package that has had applied to at least a portion thereof a reactivatable adhesive, said process comprising forming and/or sealing a package by exposing the applied reactivatable adhesive to radiant energy for a time sufficient to reactivate the adhesive, said radiant energy having a peak wavelegth of from about 400 nm to about 100,000 nm.
A form, fill and seal packaging machine comprising a frame, a plurality of stations carried by the frame, and a feeding means for feeding cartons to be formed, filled and sealed, said stations comprising a carton erection station, a bottom and/or top flap sealing station and a filling station, said top and/or bottom sealing station comprising a source of radiant energy having a peak wavelegth of from about 400 nm to about 100,000 nm.
An article of manufacture having applied on at least one substrate surface thereof an adhesive comprising an energy-absorbing ingredient and which is capable of being reactivated upon exposure to short durations of radiant energy having a peak wavelength of from about 700 nm to about 10,000 nm.
