Relative susceptibility of plastics to fracture by shock as indicated by the energy expended by a standard pendulum type impact machine. The ability to withstand mechanical abuse in service, as related to dropping and impacts.
> Ask about Impact Resistance

(1) The ability of a material to withstand shock loading. (2) The amount of energy needed to fracture, under shock loading, a specified test specimen in a specified manner.

The British gallon, equal to 277.274 cubic inches, or about 4.8 U.S. quarts.
> Ask about Imperial Gallon

A sealing technique in which excitation by means of high frequency elctric impulse causes materials to bond. Usually associated with inner seals whether they are applied separately or as an integral part (metal or platic) of the closure.
> Ask about Induction Sealing

A two-stage process of plastic bottle manufacturing where a preform or parison is injection molded. The bottle finish is formed at this time. The preform is then transferred to a blow mold where the bottle takes its final shape. A video of the process is located here.

A mold into which a plastic resin is introduced by pressure from an exterior heated cylinder.
> Ask about Injection Mold

A molding process whereby a heat softened plastic resin is forced from a heating cylinder into a relatively cool cavity which gives the product a desired shape.

Non-impact method of printing whereby tiny drops of ink are formed into letter, number or other configuration and sprayed on to the object or surface to be printed. Can be used for high speed printing. A major application is for code marking beverage cans.
> Ask about Ink Jet Printing

Process by which preprinted labels are placed in the mold before the plastic is injected into the mold. This form of labeling is very economical for large manufacturing runs, as it does not require any additional processes on the production line or post production decorating.
> Ask about In-Mold Labeling

An extra seal of comprising a sheet that is resistant to water vapor or vapor from some chemical, and adhered to the top end of a container below the regular cover or closure, to give added protection to the contents, such as: hygroscopic materials like soluble coffee, volatile chemicals such as chloroform, or creams and ointments containing volatile ingredients. The added protection includes: barrier to movement of water vapor or volatile chemicals and perfumes, and protection against tampering, contamination and leakage.
> Ask about Inner Seal

Threads on the neck finish of bottles that are not continuous, having gaps at seam areas to avoid scratching internal coatings on closures.
> Ask about Interrupted Thread

As applied to plastics, refers to bombardment with a variety of subatomic particles, generally alpha-, beta-, or gamma rays. Atomic irradiation has been used to initiate polymerization and copolymerization of plastics and in some cases to bring about changes in the physical properties of a plastic material.
