Blister Packing Machine for Medicine Packing Machine Manufacturer

There are some features for the blister packing machine below:

Integrated Molding-Filling-Sealing: This is its most fundamental feature. Multiple key processes are completed continuously on a single machine:

Molding: Rigid plastic sheets (PVC, PVDC, PP, etc.) are heated and softened, then formed into blister packs of uniform size and shape in a mold using positive pressure (blow molding) or negative pressure (vacuum forming).

Filling: Tablets, capsules, and other products are automatically (using a counting plate or vibrating hopper) or manually (for irregularly shaped or fragile items) filled into the blister packs.

Heat Sealing: Aluminum foil (PTFE) coated with heat-sealing adhesive is placed over the blister packs, and under heat and pressure, it is tightly sealed to the plastic sheet base, forming a sealed, independent unit.

Cutting: The continuous blister packs are cut into specified shapes (e.g., rows and columns).

High Speed ​​and High Efficiency: Modern high-speed blister machines can reach speeds of 300 packs or more per minute. Continuous operation and automatic control significantly improve production efficiency.

Forming Precision: Consistent blister depth and shape ensure undamaged medications during transport.

Filling Precision: Accurate counting with minimal missing or extra blister packs.

Heat Seal Strength: Uniform and secure seal ensures moisture-proof, light-proof, and airtight protection for the medications.

By changing molds (forming mold, heat sealing mold, punching mold) and adjusting some mechanisms, it can adapt to the size, shape, and plate requirements of different medications.

Adjustable parameters such as temperature (heating, heat sealing), pressure, and operating speed adapt to different packaging materials.

Automatic Detection and Rejection: Equipped with multiple online detection systems (such as visual inspection, metal detection, missing blister detection, heat seal integrity detection, etc.) to automatically reject defective products.

Human-Machine Interface: PLC and touch screen control provide intuitive and convenient parameter setting, operation, and fault diagnosis.

Data Recording and Traceability: Complies with GMP requirements, recording production batch number, expiration date, production data, etc., for easy tracking.

Unitization: Each medication is individually sealed to prevent cross-contamination.

Barrier Properties: Suitable plastic sheets and aluminum foil effectively prevent moisture, oxygen, and light exposure, extending the shelf life of the medication.

Physical Protection: Blister packs provide cushioning to prevent damage from compression during transport.

Clear Product Information: The medication name, specifications, batch number, and expiration date can be clearly printed on the aluminum foil.

Easy Access: A patient-friendly push-through design facilitates medication dispensing.

Dosage Instructions: Date or time markings on the blister packs help patients take their medication on time.

Materials: Parts of the equipment that come into contact with medication are made of easy-to-clean, corrosion-resistant, and non-reactive materials such as stainless steel.

Design: Smooth, corner-free structure for thorough cleaning and to prevent contamination. Modular design facilitates maintenance and replacement.

Anti-cross-contamination: Features excellent sealing and dust control capabilities (e.g., equipped with a dust collection device).

Modern models emphasize energy-saving design (e.g., localized heating, high-efficiency servo motors).

Scrap materials generated are easily collected and recycled.

Roller Type: Forming and heat-sealing dies are made of round rollers, resulting in smooth operation, high speed, and low noise, suitable for large-scale production of standard tablets.

Flat Type: Forming and heat-sealing dies are made of flat plates, resulting in greater forming depth, more precise blister shape, and convenient mold changing, suitable for large, irregularly shaped products or products with high requirements for blister shape (e.g., medical devices, large capsules), but the speed is generally lower than that of roller type.

Expensive Equipment: High-performance blister packaging machines (especially those for demanding industries like pharmaceuticals) have high purchase costs, potentially putting financial strain on small and medium-sized enterprises.

Complex Maintenance: The equipment has a sophisticated structure requiring regular professional maintenance. Replacing consumable parts such as molds and heat-sealing components also increases long-term operating costs.

High Dependence on Molds: Changing product specifications (e.g., tablet shape, size) typically requires mold replacement, which is time-consuming and costly, making it difficult to quickly adapt to multi-variety, small-batch production.

Limitations on Packaging Materials: Primarily suited to specific types of blister foil (PVC/PVDC/aluminum foil, etc.), its adaptability to new environmentally friendly materials (such as biodegradable materials) may be insufficient, and parameter adjustments are required when switching materials.

Speed ​​and Size Related: Packaging speed is affected by product size and blister shape; complex shapes may reduce production efficiency.

High Energy Consumption: The heating, sealing, and forming processes continuously consume electricity, especially at high speeds.

 Poor adaptability to special products: Irregularly shaped, fragile, or temperature and humidity-sensitive products may require customized designs, increasing technical complexity.

 Sealing and quality control: Improper parameter control during the heat sealing process (such as temperature and pressure) can easily lead to problems such as incomplete sealing and blister pack breakage, affecting product shelf life.

Large footprint: Integrated production lines (such as those connected to cartoning machines and checkweighing equipment) require significant factory space.

High level of operational expertise: Training of professional personnel for operation and debugging is required; troubleshooting automated systems (such as PLC control) also requires technical support.

Material waste: Scrap materials and material losses during trial runs are unavoidable, especially given the difficulty of recycling aluminum-plastic packaging, increasing environmental pressure.

Noise and heat dissipation: High-speed operation may generate noise and heat, requiring additional measures to improve the working environment.

Pharmaceutical industry: Requires compliance with GMP standards; cleaning and validation processes are complex; equipment upgrades or modifications require re-validation.

Food industry: High hygiene requirements exist, and blind spots in equipment cleaning may increase the risk of contamination.
