Types of Blister Sealing Machine

Roller type blister machine:The working rule of the roller blister packing machines is quite simple. The forming film is heated and softened by the heating device. The blister is then sucked by the negative vacuum pressure on the roller forming molding roller, and therefore the filling device fills the packaged object into the blister, then passes through the roller type.The heat sealing device seals the single-sided adhesive-coated cover film on the surface of the blister material at an appropriate temperature and pressure and seals the packaged object within the blister.Roller plate blister sealing machineThe roller plate type blister packaging machine is developed with the foundation of a roller type and flat type blister packaging machine. That is, a flat type molding device is employed for blow molding (positive pressure forming), and a roll type sealing device is sealed, and its blister packaging machine working principle is essentially the same.Flat blister sealing machineThe working rule of the flat forming blister machine: The formed film is heated and softened by the flat heating device. The softened film is blown into a blister by using compressed gas within the flat forming device, and therefore the filling device fills the package into the blister.Then, it’s sent to the flat sealing device, and therefore the cover film is sealed with the formed film under suitable temperature and pressure, then the batch number is printed, and thus the broken line is pressed by the typing imprinting device. Finally, the punching device is punched into a predetermined size product section.

What is a Blister Packing Machine?

Blister Packing Machine Details  Blister packing machines are special machines that are used as unit-dose packaging for tablets, capsules, etc. The device has a  component of a bubble pack that may be a cavity or pocket made up of a formable film, usually a thermoformed plastic or cold-formed aluminum film. This usually features a lidding seal of aluminum foil.In other words, this is an electromechanical machine that has both moving and stationary parts that aid in packaging and sealing products in pre-formed cavities.The mechanical movements facilitate the formation of sized cavities on packaging material, filling, and sealing with appropriate materials.Using different packaging materials and principles of forming, Blister Packs could also be divided into three types:aluminum/plastic (thermoforming) bubble pack, aluminum/aluminum (cold forming) bubble pack, and aluminum/plastic/aluminum bubble pack.IntroductionThe product is specially designed for hospital dosage room, laboratory institute, health care product, middle-small pharmacy factory, and featured by compact machine body, easy operation, multi-function, stroke adjustable, long durability etc, it is suitable for the Alu-PVC package of medicine, food, electric parts etc. Aided forming Pre‐cutting Inspection and rejecting control systems. Print mark registration Automatic feederRemarks:* Best option for small batches, pharmaceutical R&D and pilot plants.* It allows forming thermoplastic and cold forming materials (Alu-Alu).* It stands out for its simple operation, high reliability and compact design. Its main structure is made of stainless steel.* Automation by PLC and operation through touch screen control panel.* It has pneumatic drives, which lend it high robustness and low maintenance.* It is suggested for R&D departments, considering that its easy operation and maintenance makes it user-friendly to personnel that are not familiar with the use of blister machines. 

What is the problem with blister packaging?

ProblemFriction generated during the unwinding of the roll of thick plastic film creates static. These static charges attract contamination from the surrounding area onto the film. During the heating and forming of the film to produce the blisters, the contamination bonds to the plastic film, creating permanent inclusions and potential scrap.The warm plastic generates even more static charges as it cools. This will result in further contamination or filling issues. These issues can include contamination from operators such as hair or skin, or repelling of the product, for example medical tablets or powders, during the filling of the blister.The top sealing layer can also suffer with static issues. Statically charged products can be pulled out of the blister when applying an aluminium tamper seal, or contamination can be attracted to the plastic seal causing sealing issues or product rejection due to visible contamination.All of these problems can be avoided by controlling the static charges.SolutionRolls of material which are purchased and found to be already contaminated will need to be cleaned. A web cleaner, such as a Meech Non-Contact CyClean, mounted prior to thermoforming is ideal for removing and capturing contamination safely. An ionising air curtain such as a 957 or 959IPS will remove the contamination but will not capture it. However, static control products can be the solution where budget is limited or quality is not imperative.Controlling static charges during product packing will allow the product and clean blister packaging material to come together, preventing product misbehaviour and inclusion of contamination. This can be done using a long range ionising bar such as a Meech 929IPS or 971IPS.
