PET plastic bottles refer to PET (polyethylene terephthalate) as the main raw material and are produced by injection-blowing technology. PET plastic bottles have high transparency, smooth and shiny surface. Creep resistance, fatigue resistance, good friction resistance and dimensional stability, low abrasion and high hardness, with the greatest toughness among thermoplastics; good electrical insulation performance, low temperature influence, but poor corona resistance. Non-toxic, weather resistance, good chemical resistance stability, low water absorption, resistance to weak acids and organic solvents.
Oral liquid plastic PET bottles PET plastic bottles are mainly used for packaging food, beverages, medicines, and health care products. According to pharmaceutical preparations, it can be divided into PET plastic bottles for oral liquid preparations and PET plastic bottles for oral solid preparations. There are corresponding quality standards for medicine packaging materials certificate YBB00102002-2015 "Oral Liquid Medicinal Polyester Bottle", YBB00262002-2015 "Oral Solid Medicinal Polyester Bottle". There are very clear requirements for PET plastic bottles: 1. Appearance, 2. Material identification, 3. Airtightness, 4. Oscillation test, 5. Water vapor transmission rate, 6. Residue on ignition, 7. Dissolution test, 8. Microbial limit, 9. Abnormal toxicity.
Oral solid PET plastic bottle
Pharmaceutical manufacturers generally have stricter requirements on the microbial limit, ignition residue, microbial limit, and dissolution test in the above-mentioned tests of PET plastic bottles.
