The present invention provides a production and processing method of a plastic yogurt bottle, comprising the following steps: adding high-density polyethylene, polyphenylene ether, a toughening agent, an antioxidant, an antistatic agent and an antibacterial agent into a mixer for mixing and stirring, and performing drying treatment; adding the dried mixture into a hopper of an injection blow molding machine to complete plasticization; extruding a molten preform; performing bottle blowing to obtain a bottle body; performing cooling and shaping; and obtaining the plastic yogurt bottle after passing inspection. The present invention effectively improves the antibacterial property of the plastic yogurt bottle by adding an antibacterial agent containing nano-zinc oxide with antibacterial, bacteriostatic, deodorizing and anti-enzyme effects and nano-titanium dioxide with antibacterial, self-cleaning and anti-aging properties, avoiding bacterial adhesion on the plastic yogurt bottle during use and ensuring the quality and safety of yogurt. Moreover, reasonable multi-stage heating processing parameters are set to reduce the problem of easy bubble generation during processing of the plastic yogurt bottle, thereby improving the appearance quality of the plastic yogurt bottle.
