In the 1980s, as my country continued to introduce advanced Cosmetic Packaging plastic bottle production lines from abroad, the prelude to replacing “glass” with “plastic” was opened. Since then, plastic bottles have been widely used in the packaging field. Plastic bottles are mainly made of non-toxic high-molecular polymers such as high-density polyethylene (HDPE), polyester (PET), polypropylene (PP), polycarbonate (PC) as the main raw materials, using advanced plastic molding technology And equipment to produce various plastic bottles, mainly containing various types of capsules, tablets, powders, granules, capsules, oral liquids and other solids and liquids. At present, most of the medicines, nutraceuticals, various foods and beverages sold in the domestic market are packaged in plastic bottles. You can shop in pharmacies or supermarkets, and you can see products in plastic bottles everywhere.
Medicines and nutrition and health products mainly use polyester bottles (PET bottles) and high-density polyethylene bottles (HDPE bottles), beverages mainly use polyester bottles (PET), and daily necessities such as shampoos and shower gels use high-density polyethylene There are more bottles (HDPE bottles). The biggest feature of plastic bottle is light weight, not fragile, clean, beautiful, and some of its technical indicators and large amounts of data show that its chemical resistance, resistance to water vapor permeability and excellent sealing performance, it can completely protect the product within the validity period. The product plays a role of safety shielding and protection. No matter what material you choose, plastic bottles must first meet the requirements of non-toxic and odor-free. 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 is used for tablets. For polypropylene bottles, if transparency is required, polyester bottles (PET bottles) can be used.
For higher barrier performance, light-blocking and opaque, brown PET bottles should be used. For liquid dosage drugs, polypropylene bottles or polyester bottles are generally used as the main raw material. At present, domestic nutrition and health products and food packaging bottles are mainly made of PET or HPDE, and bottle caps are made of PP. The tightness and water vapor permeability of the bottle and cap. Tightness and water vapor permeability are two important technical indicators of plastic bottles, and they have an important impact on the stability of the packaged product. Quality standards for plastic bottles. The product quality can be analyzed and judged from the product quality standards of the manufacturer. Auditing suppliers has become an essential part of purchasing plastic bottles.
Through the audit, it is possible to make a comprehensive and correct assessment of the production plant's software and hardware facilities, technical equipment, and comprehensive quality. Recycled materials must not be used for packaging medicines, nutraceuticals, and food and beverages. The "Measures for the Hygiene Management of Plastic Products and Raw Materials for Food" promulgated by the Ministry of Health has clear regulations: "Where plastic food utensils, containers, and food packaging materials are processed , Do not use recycled plastics.” The regulations were promulgated and implemented on November 26, 1990. Plastic bottles can be seen everywhere in life. Plastic bottles are closely related to people's daily life. It can be said that no one knows that they are everywhere. There are also large-scale plastic recycling bases in China, but the supervision is not standardized, and the quality is mixed. In addition to many plastic bottles made of recycled materials, it is harmful to people's health, as well as pollution during transportation, which also seriously endangers the health of consumers.
