A die cut label that is applied to a bottle by mild pressure from a web on which it is carried. Prototype Mold A simplified mold frequently made from a light metal casting alloy or epoxy resin to produce preliminary bottles. Recessed Panel A bottle design in which the labeling area is indented or recessed. Plastic A plastic prepared from cleared and reground used goods. Resin Any of a class of solid or semi-solid organic products of natural or synthetic origin, typically of high molecular weight, with no specific melting point.

S Dimension Locates the position of the bottle thread in relation to the top of the finish. It is a vertical distance from the top of the finish to the intersection of the finish wall and the top of the first part of the thread where full depth contour exists. Thermoplastic copolymer with good scratch, chemical, stiffness, and stress-crack resistance. Shark Skin A container's surface irregularity in the form of finely-spaced sharp ridges as a result of the relaxation effect of the melt at the die exit. The dimensional decrease of a bottle after being molded, generally caused by cooling and the ensuing contraction of the plastic material.
