Four Guidelines for Plastic Bottle Production

Ⅰ. Plastic bottles are popular


Plastic bottles are widely loved by customers and distributors because of their light weight, portability, drop resistance, and acid and alkali resistance. Plastic bottles have become an important part of our daily lives.


Ⅱ. Four guidelines for plastic bottle suppliers


1. What main material and additive formula are used for plastic bottles have a vital influence on their high quality. 


There are many types of main materials when selecting, which requires us to investigate its summary function when selecting. Usually, high-density polyethylene and polypropylene bottles are used for tablets. If transparency is required, PET bottles can be used. The medicine bottle design requires higher isolation, and it should be light-blocking and opaque, so the brown PET bottle is used, and the PEN bottle is better. Liquid medicine bottles usually use polypropylene bottles or polyester bottles as the main material.


2. Tightness and permeability


Tightness and water vapor permeability are two important technical indicators for the medicine bottle design, and they play a vital role in the stability of the medicine.


3. Stability and compatibility


When choosing plastic bottles, especially new plastic bottles (or new materials, new processes) for new drugs, a charge test should be carried out first to investigate the stability of the charge and the compatibility between the plastic bottles and the drugs. The infiltration, dissolution, adsorption, chemical reaction, and denaturation of drugs and plastic bottle materials must be determined through scientific testing.


4. Product quality and guarantee system


Manufacturers of medical plastic bottles should have corresponding national and industry standards. At the same time, it is necessary to make a comprehensive and correct assessment of the manufacturer's software and hardware equipment, technical equipment, and comprehensive quality level.
