Product Description
All plastic “soda” or “pop” bottles start as a small plastic bottle called a preform. When this preform is heated and blown into a larger bottle it is ready to be filled with your favorite carbonated beverage. Our small plastic preforms come with full-sized final threaded openings so they use standard plastic soda bottle tops (included). Preforms are ~12 cm long x 2.5 cm in diameter (~5” x 1”). Interior volume of preform is approximately 28 cc (~1 fluid oz). The polymer in our baby soda bottle preforms is polyethylene terephthalate, commonly known as PET. This polymer has a monomer formula mass of C10H8O4, a melting point of 260o C, and a specific heat of 1.0 kJ/(kg-K). It has a glass temperature of 70o to 80o C, where it starts to soften. Package contains 30 preforms and 30 bottle caps
