Blister strip packaging machine

Types of blister strip packaging machines

A blister strip packaging machine is a packaging device that employs blister packaging, a method that packages goods in a plastic or polymer container (blister) and seals them into a backing material. Modern packaging machines perform this operation at lightning speed, such as those made by Gernep, Multivac, and Ima. Blister strip packaging machines are distinctive because they cover items in transparent plastic that cannot be penetrated, such as PVC or PET films. The back cover can be corrugated cardboard, paper, or any other material used for blisters. Blisters offer two major benefits: they give consumers a peek at what is within the package, and they are nearly impossible to open and counter.

Depending on the type of operation and film forming used, blister strip packaging machines can be classified into the following types:

• Automatic blister packaging machines: Automatic blister packaging machines have automated production lines with features like computerized control, sensor detection, and automatic feeding, making them easy to operate. They have a higher output than manual packaging machines to meet large-scale production requirements. They use sophisticated thermoforming technology to efficiently and quickly blister-pack items. Blister packaging machines can handle complex packaging needs for various industries and are suited for continuous high-volume production situations.
• Semi-automatic blister packaging machines: Compared to the total automation of automatic models, semi-automatic blister packaging machines usually require some manual operation, like loading products or adjusting settings. They are more versatile for different kinds of products and packaging demands. For instance, they may be able to change the size and shape of the packaging for different products better than fully automatic ones. The speed and output of semi-automatic machines are appropriate for small to medium production volumes.
• Sucktion-type blister packaging machines: The suction method of a blister packing machine uses suction nozzles to hold and shape the blister. The equipment will first place the backing material on the molding area, then employ the suction nozzles to suck the sheet to fit the contour of the mold, and finally, heat the mold to form the blister. The suction-type blister packaging machine has the advantages of precise molding and adaptability to items of varied shapes and sizes. It is quite helpful for the processing of small, complex-shaped products that call for exact specifications.
• Pressure-type blister packaging machines: Blister formation in a pressure blister packing machine is done by applying pressure to the plastic sheet. The machine will first place the backing material on the molding area, then use the pressure clamping plate to hug the plastic sheet to the mold, forming the blister. The pressure-type blister packaging machine is sturdy and long-lasting, suitable for high-volume production. It is great for packing operations calling for quickness and efficiency, and it can meet the packaging demands for large-scale output.

Specifications and maintenance of a blister strip packaging machine

Specifications

• Production capacity: The amount of packaged product produced by the machine in a given period, typically expressed in units per hour or per minute.
• Suitable size and thickness of materials: The machine's applicable material sizes and thicknesses include the size of the blister and lid materials, such as PVC, PET, PTEG, etc., as well as the parameters of the sealing materials, such as aluminum foil, etc.
• Mold customization: The shape and size of the mold can be customized to meet specific packaging requirements. It also includes the design and development of the blister shape and size to ensure that the blister and the product match perfectly.
• Speed: The machine's operating speed is typically expressed in terms of the number of packs per minute or per hour. It can also include the speed adjustment range, which can adapt to different production requirements.
• Power: The machine's power requirement, which is typically expressed in kilowatts (kW) or horsepower (HP), determines its energy consumption and capacity.

Based on the above specifications, it is essential to keep in mind that they may vary considerably depending on the machine's make and model. Therefore, to know the exact parameters and details of a particular machine, it is better to consult the manufacturer's documentation directly.

Maintenance

• Clean: Regularly clean the surface, internal and external parts of the packaging machine to remove dust, grease, and other dirt. Use suitable cleaning agents and tools to avoid damaging the equipment.
• Lubrication: Check and maintain the packaging machine's lubricating oil and lubricants regularly. Ensure that each moving part is adequately lubricated to reduce friction and wear, and ensure smooth operation.
• Check and adjust: Regularly check the packaging machine for blisters to ensure that each part is functioning well. Check whether the fasteners are loose, and adjust the equipment's parameters and positions as required to ensure that the packaging quality and efficiency are stable.
• Replace the wearing parts: The packaging machine will inevitably suffer some wear and tear over time. Please pay attention to the wearing parts, such as belts, blades, seals, etc., and replace them in a timely manner to ensure the machine's stable operation and packaging quality.
• Dustproof and waterproof: In the conditions where dust and moisture are heavy, consider using a dustproof cover or a waterproof shed to protect the packaging machine from damage.

In short, the correct operation and maintenance of the blister strip packaging machine will ensure its stable operation and service life. Meanwhile, it is essential to formulate a maintenance plan for the machine according to the actual use situation so that the machine can always be in good condition.

Usage Scenarios of Blister Strip Packaging Machines

Blister strip packaging machines serve various industries, as already discussed. Below are some of the most common applications.

• Pharmaceuticals: Blister strip machines are the most common packaging for the pharmaceutical industry.
