Several Methods For Selecting High Quality Plastic Spray Bottles

Because plastic spray bottles have many specifications, such as small dozens of milliliters, large thousands of milliliters, with or without color, transparent, diverse colors, different shapes and various categories. Facing the splendid plastic bottle market, pharmaceutical manufacturers should grasp the following principles when choosing plastic bottles:

1. Selection of main raw materials and additives formula for plastic spray bottles: The product standard for solid plastic bottles stipulates the applicable main raw materials separately, and must meet the requirements of non-toxicity and non-odor. Because there are many main raw materials available, it is necessary to select the comprehensive properties of raw materials. Generally, tablets are made of high density polyethylene, polypropylene bottles are made of polypropylene, and if transparency is required, PET bottles are chosen. If the drug needs to have higher barrier performance, light barrier and opacity, the brown PET bottle is selected, and the better barrier performance is PEN bottle. Polypropylene bottles or polyester bottles are generally used as the main raw materials for liquid formulation drugs.

2. Sealing and vapor permeability of bottle body and cap. Sealability and water vapor permeability are two important technical indexes of plastic spray bottles, which play an important role in the stability of charge.

3. Quality standard of plastic spray bottle. The quality of products can be analyzed and judged from the product quality standards of production plants. Enterprises in spray bottle enterprises should formulate enterprise standards that are stricter than national standards and industry standards.

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

5. Charge stability and compatibility of plastic spray bottles. To select plastic bottles, especially new drugs, new plastic bottles (or new materials, new processes) should be first tested for charge stability and compatibility between plastic bottles and drugs. The penetration, dissolution, adsorption, chemical reaction and denaturation of the materials of drugs and plastic bottles must be determined by scientific testing.
