1. The tightness and water vapor permeability of the bottle body and the cover. Airtightness and water vapor permeability are two important technical indicators of plastic bottles, which have a crucial impact on the stability of the packaged product.

Second, the quality assurance system. Auditing suppliers has become an essential part of purchasing plastic bottles. Through the audit, the software and hardware facilities, technical equipment and comprehensive quality level of the production plant can be correctly evaluated.

Three, plastic bottle product quality standards. The quality of the product can be judged from the product quality standard of the manufacturer.

Fourth, any plastic bottle must first meet the requirements of non-toxicity and no peculiar smell. Due to the wide variety of main raw materials available, it is necessary to select the comprehensive properties of the raw materials. Generally, high-density polyethylene and polypropylene bottles are used for tablets. If transparency is required, polyester bottles (PET bottles) can be used. If higher barrier properties are required, and light blocking and opaqueness are required, brown PET bottles are used. Liquid dosage forms generally use polypropylene bottles or polyester bottles as the main raw materials. At present, domestic nutritional health products and food packaging bottles are mainly made of PET or HPDE, and caps are made of PP.
