PET (polyethylene terephthalate) bottles are produced by stretch blow moulding — either from PET preforms (two-stage ISBM process) or directly from granules (single-stage). Clear PET is the dominant material for beverage bottles, cooking-oil and edible-oil bottles, condiment and sauce bottles, and personal care packaging due to its excellent optical clarity, mechanical strength, chemical resistance, and recyclability. Key specification decisions when sourcing PET bottles wholesale are neck finish standard, bottle capacity and dimensions, wall thickness, colour (clear, light blue, amber, custom), and whether the application requires standard virgin PET or a recycled-content rPET grade. Neck finish determines closure compatibility: PCO 1881 is the global standard for carbonated beverages; 28mm 1881 for still water and still beverages; 38mm for cooking oil, condiments, and household liquids. For cooking-oil PET bottles — typically 500ml, 1L, and 2L — the 38mm neck is most common, accepting standard cooking-oil screw caps or dispensing caps. For beverages sensitive to acetaldehyde (AA) migration — juices, dairy drinks, mineral water — specify a low-AA PET grade (AA below 1 μg/L is a typical requirement); standard PET grades have higher AA levels acceptable for carbonated soft drinks but not for sensitive still beverages. All food-contact PET bottles must be accompanied by a Declaration of Compliance (DoC) under EU Regulation 10/2011 or FDA 21 CFR.
