    Term:

    Polymers can be divided into two general chemical classes. What are they, and which is most commonly used in packaging? What is the difference in molecular structure that characterizes the two general polymer classes?

    Definition:

    Thermoplastics and thermosets are the two types of polymer classes. Thermoplastics are most commonly used in packaging. Thermoplastic polymer chains are free to pass over one another when heated. Thermoset polymer chains are cross-linked and interconnected so they can never come free of one another without destroying the material.

    Term:

    List the methods of creating a body seam on a 3-piece steel can. What are the advantages and limitations of each?

    Definition:

    Steel 3-piece can bodies can be mechanically seamed, bonded with adhesive welded or soldered. Mechanical side-seaming or clinching is used for containers intended for dry product, where a hermetic seal is not important. Adhesive bonding is an attractive body-assembly method for application where the can will not be subjected to thermal processing. Unlike welded cans, adhesive-bonded constructions can have full wraparound lithography. The welded seam line is about 30% thicker than the 2 base metal sheets. Cans shorter than 75 mm (3in.) are too short to be welded individually and are made by welding a body twice the required length and cutting it into 2 cans. Soldered food cans are no longer permitted in NA. Some soldering is still done for nonfood applications. All solders have eliminated lead content.
