The pet nutrition cream syringe is a special packaging container, which also has the function of drug delivery. The quality of the packaging plays an important role in the safety and effectiveness of the nutritional cream. There are many types of pharmaceutical packaging on the market, and the quality is uneven. The quality of this packaging can be judged by the following points:
1. Appearance: The pet nutrition ointment infusion device is made of PE material through injection molding process. The head of the needle tube should be flat, free of burrs, bends, cracks, and gag defects. The inner wall of the tube body is flat and smooth, with no color difference. The cap is full-formed, uniform in color, without cracks and deformation. The putter has full forming, uniform color and no deformation. The piston is fully formed, without flashing, and without obvious shrinkage.
2. Airtightness: This kind of packaging has higher requirements for airtightness. When selecting a syringe, the airtightness should be tested. Fill half of the water in the syringe, insert the piston into the syringe, remove the protective cap, and eliminate residual air. Then block with a protective cap, and apply an axial pressure of 30N on the push rod rubber plug inside the syringe through the push rod, and keep it for thirty seconds. There should be no leakage at the seal of the cap and the piston.
3. Production environment: This kind of packaging is directly in contact with the nutritional cream, and its microbiological limit must meet the standard requirements. Generally, it should be produced in a clean workshop that meets national standards. If the veterinary drug manufacturer has higher requirements for the microbial limit, additional environmental protection can be carried out. Oxyethane sterilization or cobalt 60 irradiation sterilization.
The quality of the pet nutrition cream paste syringe can be judged by the above points. Only high-quality packaging can ensure the good storage state of the nutrition cream, which is conducive to the healthy growth of pets.
