How Is the Beverage Bottle Made?

The mineral water and beverage we usually drink and the peanut butter we eat are all ladled in plastic bottles. Compared with glass bottles, the use of plastic bottles is not only of low cost, but also invulnerable to breaking. However, some people discard it at will after using it, which has caused a lot of environmental problems.

Today, let's take a look at how the plastic beverage bottles in your hand is actually processed. First of all, plastic bottles are made of polyethylene terephthalate (PET). This material has good mechanical performance, impact strength is 3-5 times that of other films, and also has good high temperature and low temperature resistance. At the same time, the permeability of gas and water vapor is low, and it has excellent gas, water, oil and odor resistance. Of course, as the most important food packaging, the key is that PET is non-toxic, tasteless, hygienic and safe, and can be directly used in food packaging.

First, the automatic mixer mixes PET particles with recycled PET fragments. Reprocessing can make plastics lose some physical properties, so the recovery content can exceed 10%. The PET from the mixer is transported to the plastic injection machine. The temperature in the injection tube is heated to 315 degrees Celsius, which makes the PET become a thick plastic liquid. Then the machine will use high pressure to hydraulic the plastic onto the die. This step is called preforming of the plastic. Thanks to the cooling system, the preforms is almost rapidly harden. These preforms are then sent to the reheat stretch bottle blower. The preform is heated to a plastic temperature, and then the preform is placed on a pole and placed in a die. At the same time, the water-cooled circulating system can rapidly cool down the forming parts. The reheat stretch bottle blower can produce 10,600 bottles per hour. Subsequently, the produced plastic beverage bottles can be ready for shipment to the juice factory. However, before the departure, the factory will also conduct a sample survey to conduct a press test on bottles.

Note that the recycled PET fragments added in production are some of the fragments in the production process, not the waste recycling of bottles and cans after use. The waste recycling of these bottles and cans will be used in other non-food related fields.
