How To Select Plastic Bottles?

The development history of plastic bottles:

In the 80s of the 20th century, with the continuous introduction of advanced plastic bottle production lines from abroad, the prelude to replacing "glass" with "plastic" kicked off, and plastic bottles have been widely used in the field of packaging. Plastic bottles are mainly non-toxic 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 a variety of plastic bottles, mainly containing various capsules, granules, tablets, powders, gel pills, oral liquid and other solid and liquid.

The use of plastic bottles:

At present, most of the medicines, nutritional health products, and various foods and drinks sold on the domestic market are packaged in plastic bottles, and you can see products packaged in plastic bottles everywhere in pharmacies or supermarkets. Drugs and nutritional health products mainly use polyester bottles (PET bottles) and high-density polyethylene bottles (HDPE bottles), drinks mainly use polyester bottles (PET), and daily necessities such as shampoo and shower gel use high-density polyethylene bottles (HDPE bottles). The biggest feature of plastic bottle is light and unbreakable, clean and beautiful, and some of its technical indicators and a large number of data show that its chemical resistance, water vapor penetration resistance sealing performance is excellent, it is complete

It can play a role in safety shielding and protection of the products installed within the validity period.

The principle of choosing plastic bottles:

1. No matter what raw materials are selected for plastic bottles, first of all, it must meet the requirements of non-toxic, no peculiar smell, etc., due to the variety of main raw materials available for selection, which requires the comprehensive performance of raw materials to be selected, general tablets use high-density polyethylene, polypropylene bottles, such as the need for transparency can be used polyester bottles (PET bottles) such as the need for higher barrier performance, and light blocking, opaque, then the use of brown PET bottles liquid dosage form drugs generally use polypropylene bottles or polyester bottles as the main raw materials.

At present, the packaging bottles of domestic nutrition and health products and food are mainly made of PET material or HPDE, and the bottle cap is made of PP material.

2. Bottle body and cap tightness, water vapor permeability. Tightness and water vapor permeability are two important technical indicators of plastic bottles, which play a crucial role in the stability of the packaged product.

3. Plastic bottle product quality standards. From the product quality standards of the production plant, the quality of the product can be analyzed and judged.

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

5. Secondary recycled materials must not be used for packaging medicines, nutritional health products, food and beverages.
