This method of printing utilizes printing plates rather than silk screens to transfer the ink to the containers. Offset printing is more exact than silk screening, and is practical for multiple color labeling. Offset printing is utilized primarily on round containers. Because plates are engraved for each color rather than making screens, offset is more expensive than silk screening.

Polyallomer is an essentially linear copolymer with repeated sequences of ethylene and propylene. It combines some of the advantages of both polymers. Polyallomer is autoclavable, and offers much of the high temperature performance of polypropylene. It also provides some of the low temperature strength and flexibility of polyethylene.
Polycarbonate is window-clear, amazingly strong, and rigid. It is autoclavable , nontoxic and the toughest of all thermoplastics. PC is a special type of polyester in which dihydric phenols are joined through carbonate linkages. These linkages are subject to chemical reaction with bases and concentrated acids, cydrolytic attack at elevated temperatures (e.g. during autoclaving), and make PC soluble in various organic solvents. For many applications, the transparency and unusual strength of PC offset these limitations.

A high molecular weight organic compound, natural or synthetic, whose structure can be represented by a repeated small unit, the polymer; i.e., polyethylene, rubber, cellulose. Synthetic polymers are formed by addition or condensation polymerization of monomers. If two or more monomers are involved, a copolymer is obtained. Some polymers are elastomers, some plastics.
Polyolefins are high molecular weight hydrocarbons. They include low-density and high-density polyethylene, and polypropylene. All are break resistant, nontoxic, and non-contaminating. These are the only plastics lighter than water. They easily withstand exposure to nearly all chemicals at room temperature for up to 24 hours. Strong oxidizing agents eventually cause embrittlement. All polyolefins can be damaged by long exposure to ultraviolet light.
Polypropylene is similar to polyethylene, but each unit of the chain has a methyl group attached. It is translucent, autoclavable, and has no known solvent at room temperature. It is slightly more susceptible than polyethylene to strong oxidizing agents. It offers the best stress-crack resistance of the polyolefins. Products made of polypropylene are brittle at ambient temperature and may crack or break if dropped from benchtop height. Used in film, in sheet and for molded rigid containers.
