Plastic bottle development history: In the 1980s, with my country's continuous introduction of advanced plastic bottle production lines from abroad, kicked off the "Plastic" "" "glass", from this plastic bottle is used in the packaging area. Plastic bottles are mainly based on non-toxic polymer polymers such as high-density polyethylene (HDPE), polyester (PET), polypropylene (PP), polycarbonate (PC), using advanced plastic molding processes And equipment produce a variety of plastic bottles, mainly in various capsules, granules, tablets, powders, gum pills, oral liquids, etc. Solids and liquids. Second, the use of plastic bottles: currently selling drugs, nutrient health products, most food and drinks sold in the country, using plastic bottles, you went to the pharmacy or supermarket to visit the products where plastic bottles are available everywhere.

The largest feature of plastic bottles is the quality of light and unrestrained, clean and beautiful, and some of its technical indicators and large amounts of data indicate their chemical resistance. The water-resistant vapor permeability sealing performance is excellent, it can completely carry out products in the validity of the product. The role of safety shielding and protection. Third, choose the principle of plastic bottle: 1. No matter what raw material, the plastic bottle is selected, first must be in line with non-toxic, no taste, etc., due to the wide variety of primary raw materials, this requires the need to use the comprehensive performance of raw materials. General tablets use high-density polyethylene, polypropylene bottles, if the transparency available polyester bottle (PET bottle) is required, if the barrier properties are higher, and the resistance, opaque , Or polyester bottle as a main raw material.

At present, domestic nutrition and health products and food packaging bottles are mainly made with PET or HPDE, and the cap is pp. 2. Sealing of the bottle and the cover, water vapor permeability. Sealing and water vapor permeability is two important technical indicators of plastic bottles, which plays an important impact on the stability of the packaged product.

3. Plastic bottles product quality standards. From the production plant product quality standards, it can analyze the quality of the product quality. 4. Quality assurance system.

Audit the supplier has become an important part of purchasing plastic bottles. Through auditing, a comprehensive correct assessment can be made to the production plant's soft, hardware facilities, technical equipment and quality comprehensive levels. 5. For packaging drugs, nutritional health products, food drinks must not use recovery materials.

The "Method of Health Administration of Food Plastics and Raw Materials" promulgated by the Ministry of Health has clear regulations: "Where the processing plastics, containers, food packaging materials may not use recycled plastics." Fourth, plastic bottle status Ministry "food The use of plastic products and raw materials hygiene management methods have clear provisions: "Where the processing plastic mold, container, food packaging materials must not use recycled plastics." Recycled waste plastics can be processed into other items.
