How To Solve The Problems Of Blister Forming And Hot-pressing Sealing In Blister Packaging Machine?

With the rapid development of national economy and the support of favorable policies, the domestic manufacturing industry has a bright future.

In recent years, the aluminum-plastic blister packaging of medicines has developed rapidly in China. Due to the characteristics of long storage period and convenient carrying, this type of packaging is more and more popular among pharmaceutical companies and consumers.

Traditional glass bottle packaging and bulk packaging are being gradually replaced, and aluminum-plastic blister packaging has become the mainstream of solid pharmaceutical packaging.

Compared with general packaging machines, its outstanding feature is that it is equipped with a small-diameter negative pressure forming roll-type suction mold roll.

And cooperate with the heat sealing roller to complete the two functions of heat sealing together with the heated PTP aluminum foil and the PVC rigid sheet, and then enter the punching and punch out the finished plate after heating and typing.

This machine is applied to the aluminum-plastic blister packaging of various scales’ capsule, tablet, injectors in the pharmaceutical industry, hospital, food, electric and other industries.

According to the different forming methods, the aluminum-plastic blister packaging machine can be divided into roller type and flat type.

The flat-type positive pressure forming effect is better than the roller vacuum forming; The effect of flat-plate heat-pressing sealing is better than that of roller-type heat-pressing sealing, and the roller-type heat-pressing sealing is superior to flat-plate heat-pressing sealing in terms of speed and reliability.

According to the professionals’ experience, the aluminum-plastic blister packaging machines are prone to problems in blister forming and hot-pressing sealing during use.

The blister forming problem. The professional pointed out that according to the principle of blister forming, PVC film/(hard sheet) is heated and then passed through a mold and formed into a blister of the required shape and size by compressed air or vacuum, so when there is a problem with the formed blister, it needs to be Start from the following aspects.

Whether the PVC film/(hard sheet) is an eligible product; Whether the temperature of the heating device is too high or too low; Whether the surface of the hearing device is adhered to PVC/; Whether the forming mold is qualified, whether the forming hole is smooth, whether the air hole is unobstructed;

Whether the cooling system of forming mould works normally and effectively; Whether the vacuum degree and exhaust rate of roller negative pressure forming reach the normal numerical value; Whether the compressed air from the flat positive pressure machine is clean and dry;

Whether its pressure and flow can reach at normal numerical value. You should make sure that there is no abnormal loss in the pipeline; Checking the Flat positive pressure molding mold is parallel to clamping PVC/ belt whether there exists air leakage phenomenon or not.

About the hot pressing sealing problem, expert on this industry pointed out that in the hot pressing sealing process of drum type aluminum-plastic blister packaging, PVC/ tape and aluminum foil are made of parallel roller hot sealing roller and aniline roller under a certain temperature and pressure to complete the hot pressing sealing.

The contact between the hot sealing roller and the aniline roller is linear, and the pressure required is relatively small.

In the hot-pressing sealing process of flat aluminum-plastic blister packaging, PVC/tape and aluminum foil are hot-pressed in the same plane by parallel flat heat-sealing plates and mesh plates under the action of certain temperature and pressure. sealed. The contact between the heat sealing plate and the anilox plate is a planar contact, and the required pressure is relatively large.

In order to improve the performance of the blister packaging machine, some companies strictly manage from structural design, manufacturing to inspection, starting from structural design, continuously improving and accumulating design and production experience.

Through standardized production, inspection and confirmation whether the performance parameters of the selected blister packaging machine conform to the production process.

Through a series of instructions and data provided by the test to prove the reliability and stability of the equipment in production, until the indicators of the product meet the process requirements and meet the GMP requirements can you deliver the machine to the client.

In terms of the function of the blister packaging machine, for you or for your company, the ideal equipment is an equipment that spends less money and has a large production volume.

At present, many blister packaging machines on the market occupy less space, have low investment, multi-functional use, high efficiency, no pollution, and low noise, and are widely used in purification workshops and hospital reagent rooms.

In addition to the continuous development of automation and intelligent technology, the degree of the automation of muti-functional blister packaging machine has been greatly improved, and the function is complete. It is suitable for capsules, plain tablets, sugar coatings, capsules, injections, special-shaped, etc. food, electronics.

We can clearly find that the market scale of aluminum-plastic blister packaging machines is gradually expanding, and the product equipment is developing in the direction of high-precision, fully automatic and intelligent.

Although the current domestic aluminum-plastic blister packaging machines can basically meet the needs of domestic pharmaceutical packaging, enterprises will still encounter many challenges in the future development.

With the increasingly fierce market competition, pharmaceutical machine equipment manufacturers must also attach great importance to technological innovation and increase investment in research and development in order to stand out among many equipment.

Last but not least, when we talk about the medicine, you should know that drug safety is not only related to the lives of thousands of households, but also the lives of pharmaceutical companies.

As an important equipment for pharmaceutical packaging, the continuous advancement and breakthrough of its technology can not only better improve the production efficiency of pharmaceutical packaging enterprises, but also better ensure the safety of pharmaceuticals and further reduce risks.So as to provide safer and more reliable medicines for the medical field and the whole human society.
