In 1980s, China continually introduce advanced plastic bottle production line from abroad. That is the beginning of the "plastic" generation, since then plastic bottle was widely used in the packaging field. They are mainly made of non-toxic high polymer such as high-density polyethylene (HDPE), polyester (PET), polypropylene (PP), polycarbonate (PC), use advanced plastic molding technology and equipment to produce varietys of plastic bottles, mainly containing all kinds of liquid and solids such as capsules, tablets, powders, granules, plastic pills, oral liquid.


First, the use of plastic bottles:

In present domestic market, lots of products are packed in plastic, like drugs, nutritional health products, food and drinks, you can see so many products packed with plastic bottles in pharmacies or supermarkets. Pharmaceutical and nutritional health products are mainly used in polyester bottles (PET bottles) and high-density polyethylene bottles (HDPE bottles), beverages mainly use polyester bottles (PET), daily necessities such as shampoo, bath gel use of high-density polyethylene bottles (HDPE bottles) more.


The biggest feature of plastic bottle is light weight, not easy to break, clean and beautiful, and its technical indicators and a large number of data shows that its chemical resistance and water vapor permeability sealing perform great, It can effectively protect the product from damp and damage within the validity period.


  

Second, the principle of choosing plastic bottle:

1, no matter what material you choose to make plastic bottles, it must comply with non-toxic, no peculiar smell, or more requirement. Due to the variety of main raw materials available, we select raw materials in consideration of comprehensive performance. Generally, HDPE bottle and PET bottles are more selected to used for medicine, if it must be transparent, PET bottles is more better, amber PET bottle can be selected if it need higher barrier performance and not-transparency. At present, the domestic nutrition health products and food packaging bottles are mainly made of PET or HPDE, and the bottle caps are made of PP materials.


2, Sealability and water vapor permeability of the bottle and its lid. They are two important technical indexes of plastic bottles, which have important influence on the stability of packaged products.


3, Plastic bottle product quality standards. We can analyze and judge the quality of products from the product quality standard of the production plant.


4. Quality Assurance System. Audit of suppliers has become an essential part of purchasing plastic bottles. Through the audit, we can clearly know the production plant's software and hardware facilities, technical equipment, quality comprehensive level and make a comprehensive and correct assessment.


5, Used for packaging drugs, nutrition and health products, food and beverages, it must not use recycled materials. The Ministry of Health promulgated the "Food plastic products and raw materials hygiene management measures", on this has a clear stipulation: "Where processing plastic utensils, containers, food packaging materials, shall not use recycled plastic." "The regulations were issued on November 26, 1990.



Plastic bottles are everywhere in life now, they are closely related to people's daily life, many plastic bottles can be reused once again, recycled old plastic can be processed into other plastic supplies. At present, many businesses are now driven by profits,they may choose low-cost recycling materials to produce bottles, this behavior really let buyers worry unceasingly. If you see impurities in the bottle during use, or if the transparency of the transparent bottle is low, you need to be vigilant.


Our factory has been producing plastic bottles for more than ten years, we use 100% new virgin material, follow the product quality standards, and have our own a set of quality assurance system. We mainly produce plastic beverage bottles and plastic cosmetics bottles, they are so relevant to people's health. We also use 100% virgin material to produce big size plastic container like engine oil bottle and lubricant oil bottle unless you insist on using recycled material.
