The resulting thermoplastic can be used to form articles with surfaces possessing a lower heat sealing temperature and, thus, improved processibility.
In preparing articles by heat sealing thermoplastic surfaces, it is preferred that all of the respective surfaces comprise the branched polyolefin as described herein. More preferably, the various surfaces are made essentially only with the branched polyolefins described above as the thermoplastic polymer, still more preferably from such branched polyolefins prepared from the same monomer(s), and especially when each of the surfaces is the same polymer. Of course, in addition to the branched polyolefins (and other thermoplastic polymer components), the surfaces can contain other additives and adjuvants commonly found in heat sealing thermoplastics such as, for example, antioxidants and stabilizers, colorants, processing aids and the like.
More than two surfaces may be sealed together, for example three films may be sealed together, and preferably all of the surfaces being sealed are of the same branched polymer as described herein.
Heat sealing may be done by any variety of methods well known to those skilled in the art. See for instance Plastic Films, Technomic Publishing Co., Inc., Lancaster, Pa., U.S.A., 1992, especially p.152-153 and 173-175. Preferably the heating of the areas to be sealed is done by thermal conduction from a hotter material (e.g., sealing bar(s) or roller(s)), by microwave heating, dielectric heating, and ultrasonic heating. The amount of pressure used may vary from that needed to contact the two (or more) surfaces to be sealed, for example finger pressure to pressure applied by presses or rollers, for example up to 700 kPa (100 psi). The heating may be before, or simultaneous with the application of pressure. Although pressure may be applied before heating, it will normally not be effective until the heating is carried out. Generally speaking, the temperatures of the polyolefin surface that is being sealed will be about 50xc2x0 C. to about 110xc2x0 C. This temperature will depend to some extent on the amount of pressure used, higher pressures allowing lower temperatures, since higher pressures cause

Preferably the heating of the area to be sealed is done by thermal conduction from a hotter material (e.g., sealing bar(s) or roller(s) ), by microwave heating, dielectric heating, and supersonic heating. The amount of pressure used may vary from that necessitate to contact the two (or more) surface to be sealed, for model finger pressure to atmospheric pressure applied by presses or roller, for example up to 700 kPa (100 pounds per square inch). The heating may be before, or simultaneous with the lotion of pressure. Although pressure may be applied before heating, it will normally not be effective until the heating system is carried out.
