First, the development history of plastic bottles:

In the 1980s, with the continuous introduction of advanced plastic bottle production lines from abroad, the prelude of replacing "glass" with "plastic" was opened. Since then, plastic bottles have been widely used in the field of packaging. Plastic bottles are mainly made of non-toxic high molecular polymers such as high-density polyethylene (HDPE), polyester (PET), polypropylene (PP), and polycarbonate (PC) as the main raw materials, using advanced plastic molding technology. And equipment to produce all kinds of plastic bottles, mainly containing all kinds of capsules, tablets, powders, granules, capsules, oral liquids and other solids and liquids.

Second, the use of plastic bottles:

At present, most of the medicines, nutritional and health care products, various foods and beverages sold in the domestic market are packaged in plastic bottles. If you go to pharmacies or supermarkets, you can see products packaged in plastic bottles everywhere. Medicines and nutritional 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 many bottles (HDPE bottles). The biggest feature of plastic bottles is light weight, not easy to break, clean and beautiful, and some of its technical indicators and a large number of data show that its chemical resistance, water vapor permeability resistance and sealing performance are excellent, it can completely protect the product within the validity period. The product acts as a safety shield and protection.

3. Principles for choosing plastic bottles:

l. No matter what raw material is chosen to make a plastic bottle, it 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 is used for tablets. Ethylene and polypropylene bottles. If transparency is required, polyester bottles (PET bottles) can be used. If higher barrier properties, light blocking and opacity are required, brown PET bottles are used. Liquid dosage forms generally use polypropylene bottles or polyester bottles. as the main raw material. At present, domestic nutritional health products and food packaging bottles are mainly made of PET or HPDE, and caps are made of PP.

2. The tightness of the bottle body and the cap, and the water vapor permeability. 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.

3. Quality standards for plastic bottle products. The quality of the product can be judged from the product quality standard of the manufacturer.

4. Quality assurance system. 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 level.

5. Recyclable materials must not be used for packaging medicines, nutritional health products, and food and beverages. The "Measures for the Hygiene Management of Plastic Products and Raw Materials for Food" issued by the Ministry of Health has clear regulations on this: "All processing plastic tableware, containers, food The packaging materials shall not use recycled plastics." The regulations were issued and implemented on November 26, 1990.

Fourth, the current situation of plastic bottles

Plastic bottles can be seen everywhere in life, and plastic bottles are closely related to people's daily life. There are also large 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.

The Ministry of Health's "Measures for the Hygiene Management of Plastic Products and Raw Materials for Food" has clear regulations on this: "Recycling plastics shall not be used for processing plastic tableware, containers, and food packaging materials." The recycled waste plastics can be processed into other products. At present, driven by interests, many businesses often choose low-cost recycled materials to make products, which is indeed worrying. If you find impurities on the bottle during use, and the transparency of the transparent bottle is low, you should be vigilant and polish your eyes.
