Pre-filled veterinary drug supplements are veterinary products where the medication is pre-packaged in a syringe-like container. Commonly found in nutritional pastes and therapeutic agents, their core design includes components such as a barrel, plunger, piston, and protective cap. The plunger usually features a graduated scale and can be used with a positioning ring to control the dosage.
The advantages of pre-filled packaging mainly lie in three aspects: precise dosage, convenient operation, and reduced residue:
• Precise dosage: The graduated scale and positioning ring allow for precise dosage setting, avoiding the negative effects of overdosing or underdosing on efficacy or causing undue burden on the animal, especially suitable for situations where dosage is calculated based on body weight, such as calf nutritional paste.
• Convenient operation: Combining storage and administration functions, simply remove the protective cap and push the plunger to complete administration, eliminating the need for additional tools and simplifying the feeding process.
• Reduced residue: The plunger pressure efficiently dispenses the medication, resulting in less residue compared to soft tube packaging, improving drug utilization.
This packaging is widely used in various veterinary drug applications:
• Nutritional supplements: Such as calf nutritional paste and pet nutritional paste, ensuring precise feeding.
• Local treatment: For example, mastitis medication for dairy cows and oral pastes for horses, often using small volumes (e.g., 5ml–30ml) to suit local administration needs.
• Special uses: Some cockroach baits also use this packaging for targeted application.
The pre-filled design, through integration and precise control, improves drug administration efficiency and safety, making it a common solution for veterinary drug packaging.

A tube filling machine is a piece of automated equipment designed to accurately fill, seal, and often trim various types of tubes, including plastic, laminated, and aluminum tubes, with semi-solid or viscous products such as toothpaste, creams, ointments, and gels. These machines are crucial in the pharmaceutical, cosmetic, chemical, and food industries, providing clean and precise filling at high speeds, with sealing methods adapted to the tube material, such as hot-air or ultrasonic sealing for plastic/laminate tubes and folding/crimping for aluminum tubes.

How a Tube Filling Machine Works:
Tube Feeding: Tubes are loaded into the machine, often automatically into holding cups.
Filling: The precisely measured product is dispensed into the open end of the tube.
Sealing: The end of the tube is sealed to prevent leakage.
Plastic/Laminate Tubes: Heated or ultrasonic sealing methods are used.
Aluminum Tubes: Mechanical folding and crimping devices are used.
Trimming (Optional): The sealed end of the tube may be trimmed for a neat finish.
Coding (Optional): A lot number or other coding can be embossed on the sealed area.
Discharge: The filled and sealed tube is then discharged for further processing or packaging.

Industries and Products
Pharmaceuticals: Ointments, creams, gels, and other semi-solid medications.
Cosmetics: Creams, lotions, toothpaste, and gels.
Food & Beverage: Certain pastes and viscous food products.
Chemicals: Adhesives, glues, paints, and other chemical products.
