Food Grade BPA free Plastic Bottle Preforms

Plastic Bottle Preforms are semi-finished structural components produced via an injection molding process. Resembling test tubes in appearance, they feature a standard threaded bottle neck structure at one end and a closed base at the other. During the manufacturing process, plastic granules are melted under high heat and injected into precision molds, where they cool and solidify to form preforms of uniform dimensions and weight. These products are supplied in bulk batches during the manufacturing phase; their standardized specifications facilitate subsequent stretching and molding processes. Plastic Bottle Preforms incorporate complete standard neck dimensions—such as the globally recognized 28mm and 30mm specifications—thereby ensuring precise compatibility with caps during subsequent sealing. Dimensional tolerances are strictly controlled, with typical error margins kept within ±0.1mm to meet the stability requirements of industrialized production. Depending on the specific design,…
