Pet Bottle Preform Special Inspection

21 mar

PET bottles are re-processed by blow molding to form plastic bottles, including bottles for cosmetics, medicine, health care, beverages, mineral water, reagents, etc. This bottle making method is called two-step method, that is, preforming by injection molding, and again A method of blow molding to form a PET plastic bottle.

Conventional testing of Pet Bottle Preform has bottle wall thickness detection, pressure resistance test, and bottle cap open fatigue detection. PET manufacturers have their own quality inspection department.

PET is a milky white or pre-yellow highly crystalline polymer with a smooth and shiny surface. It is resistant to creep, fatigue, friction and dimensional stability, low wear and high hardness, and has the highest toughness in thermoplastics. It has good electrical insulation properties and is less affected by temperature, but has poor corona resistance. Non-toxic, weather-resistant, chemical-resistant, good water absorption, low acid resistance and organic solvents, but not soaked in heat-resistant water, not resistant to alkali.

The above is the PET packaging bottle introduced by Jilian Plastics. We believe that through the above, we have a certain understanding of the production process and quality inspection of Pet Bottle Mould.
