Abstract

The invention provides a production and processing method of a plastic yoghourt bottle. The method comprises the steps of adding high-density polyethylene, polyphenyl ether, a toughening agent, an antioxidant, an antistatic agent and an antibacterial agent into a mixer, mixing, stirring, and drying; adding the dried mixture into a hopper of an injection blow molding machine to complete plasticization; extruding a molten bottle blank; blowing the bottle to obtain a bottle body; carrying out cooling and shaping; and obtaining the plastic yoghourt bottle after the inspection is qualified. The antibacterial property of the plastic yoghourt bottle is effectively improved by adding the antibacterial agent with antibacterial, odor-removing and enzyme-preventing nano zinc oxide and nano titanium dioxide with antibacterial, self-cleaning and anti-aging properties, bacteria are prevented from being attached to the plastic yoghourt bottle during use, the quality safety of yoghourt is guaranteed;and moreover, by setting reasonable processing parameters of multi-section heating, the problem that bubbles are easily generated in the process of processing the plastic yoghourt bottle is reduced, and the appearance quality of the plastic yoghourt bottle is further improved.

Description

technical field [0001] The invention relates to the technical field of processing plastic yogurt bottles, in particular to a production and processing method of plastic yogurt bottles. Background technique [0002] Yogurt is a kind of milk product made of milk, after pasteurization, beneficial bacteria starter is added to the milk, and after fermentation, it is cooled and filled. Yogurt products are mostly solidified, stirred and added with various fruit juices The fruity type of auxiliary materials such as jam is more. Yogurt bottle is a kind of utensil used to hold yogurt. More and more yogurts are packaged in plastic bottles. However, the existing plastic yogurt bottles have the problem of unsatisfactory antibacterial properties. Bacteria are not conducive to the quality and safety of yogurt, and the plastic yogurt bottles produced and processed are prone to air bubbles, which seriously affect the appearance quality of plastic yogurt bottles.
