    Brief introduction to the process of PET hot filling bottle

    PET hot-filled bottles are molded under high blowing pressure (above 33bar) and high mold temperature (above 120 ° C). The bottle has a high crystallinity (30%), has good heat resistance, and can be used in After filling the contents of 80 ℃ ~ 95 ℃, there is no obvious bottle deformation such as bot... read more

  • Requirements of PET bottles for hot filling process

    Requirements of PET bottles for hot filling process

    The hot-filling process is mature and the product risk is low. The requirements for PET bottles are mainly reflected in: 1. The center temperature of the material liquid during filling is 89 ± 1 ℃, which requires the bottle to have good heat resistance and overcome the influence of heat on the shape... read more

    Method for adjusting full-mouth capacity of PET hot-fill bottles

    Bottle full mouth capacity The full capacity of PET hot-filled bottles will affect the thermal deformation of the PET hot-filled bottles of the product. When the full-filled capacity of the bottle is too large, the product is prone to bottle pinching, or the consumption is increased due to the large... read more
