2 ENVELOPES AND METHODS FOR THEIR PRODUCTION EP11835354.9 2011-10-27 EP2632816A1 2013-09-04 MACGREGOR, Christian
An envelope is formed from continuous COPP film web by pre-creasing envelope body (13) and flap (14) fold lines along the web, continuously installing an adhesive tape along the flap portions and pre-cutting relief slots in the web corresponding to the flap side edges (15). The pre-creased web is folded and cut into individual envelopes by hot knife cutting, whereby the presence of the slots prevents the flaps from welding to the side seams even with the flap folded over. Envelopes produced by the method are suited to automatic stuffing. Apparatus for making envelopes in accordance with the invention is also described.

6 Method for making a non-peelable, sterilizable bag US885641 1997-06-30 US5976299A 1999-11-02 Brian W. Ivey
A method for making a non-peelable, sterilizable receptacle having a low particulate count for receiving articles for storage in pharmaceutical intermediate processing. This method involves providing a continuous first web of polyolefin film, providing a continuous second porous web of spun-bonded polyolefin film. The webs are advanced through cleaning processes that include an anti-static device, an ultrasonic vibrating device and a vacuum device. The two clean webs are then brought together and passed into the heat sealing section. The webs are heated welded together by forming continuous seams on the webs to form an open pouch. The seams are made by applying opposing platens at a pressure between about 30 to about 40 psi to both the webs and a heat welding element at a temperature of about 330.degree. to about 380.degree. F. against only the first web. This causes the first web to melt into the pores of the second web. The seams are then cooled to produce a welded seam having a pull resistance of greater than five pounds per linear inch. The webs welded are then cut in between the seams to form the receptacle.

20 Method and apparatus for registration of a seal on a plastic bag US289426 1994-08-12 US5587032A 1996-12-24 Stephen A. Saindon; Peter J. Gietman, Jr.; Nicholas J. Nagel
A plastic bag making machine includes a cylindrical drum with a variable diameter. A plurality of seal bars define the circumference of the drum, and are substantially parallel to the drum's rotational axis. The bags are made from a plastic film with registration marks that are detected by a detector disposed near the film. A detector also detects each revolution of the drum and an encoder provides signals indicative of the position of the film. A controller determines the distance phase of the registration marks and the rum size error. The drum diameter is adjusted in response to an output of the controller in such a way as to correct for both the initial drum size error, the initial phase error, and the phase error accumulated while the drum diameter is being corrected.
