Blister coating is a well-known thin and transparent polymer film technique used on metal substrates to protect them from corrosion and other adverse environmental effects. These coatings are also known as moisture-barrier or rust-inhibiting coatings because they prevent moisture from reaching and corroding the substrate.
A Blister Coating is a thin, transparent, protective layer applied to metal surfaces for corrosion resistance and appearance.
Another alternative method anyone can use is the Heat Sealing process. Laboratory heat Sealer is used to seal products, packaging, and other thermoplastic materials with heat. This is also a good thing, and many companies are using it.
Heat sealing can join two similar or dissimilar materials, one of which has a thermoplastic layer.
Blister Packs
Blister Packs are thin, transparent packages made of plastic or laminated paper. These packs protect small items such as pills, jewelry, toys, etc. They are also known as bubble packs or snap packs.
Blister packs provide an optimum combination against external influences. Blister coating can extend the shelf life of your products by providing an added barrier against moisture, air, oils, fats, and odors. Some standard blister components are PVC, PVDC, PCTFE, COC, Cold from foil, and Lidding foils.
Blister packing is most commonly used to package pills or small tablets which have a high value and need an effective way to protect them against moisture and contaminants while staying clear enough that their appearance is not compromised.
Benefits of Blister Coating
Blister coating provides several benefits, including:
1) It protects the medication from the environment, preventing it from becoming degraded or damaged.
2) It provides a barrier against moisture, oxygen, and other contaminants.
3) It can prolong the shelf life of the medication.
4) It can provide a tamper-evident seal, ensuring the medication has not been tampered with.
5) It can make the medication easier to handle and less likely to break or crumble.
Therefore, Blister Coating can improve the shelf life of a product by protecting it from degradation.
How is Blister Coating applied?
Blister Coating is applied by mixing the drug with a cube of sugar and then adding a gum acacia solution. The mixture is then heated until it forms a sticky mass that can be shaped into a blister.
One of the most famous Blister Coating:
Full-flange Coating:
The most popular blister coating method is with a full-flange tank, in which the casting consists of two pieces that fit together, with a gap between them into which the molten steel is poured.
Once this is done, the casting is covered with a layer of protective steel and then a layer of steel plate. But before the steel plate is applied, the inside of the casting is sprayed with a layer of flux and then cured with an electric blanket.
How long does Blister Coating last?
Blister Coating typically lasts for around 2-3 days. However, it is important to note that this will vary on several factors, including the type of coating used, the environment in which it is used, and the level of care and maintenance applied to it.
I was generally speaking. However, most blister coatings will last for several years before needing to be replaced.
A Blister Coating that is exposed to moisture or humidity will not last as long as one that is kept in a dry environment.
Different Heat Sealers
To meet the needs of various purposes, a variety of Laboratory Heat Sealers are utilized.
Here are a few examples: These are constructed with moving belts placed over the heating components and are known as continuous or band type heat sealers.
Hot Bar Sealer: These sealers come with heated dies, bars, and other accessories. In these sealers, the temperature of the bars is kept constant, effectively contacting the material to form a solid connection between two substrates. The bars that are put together in hot bar sealers can be given to customers in a variety of configurations, depending on the needs of their applications.
Conclusion
In today’s advanced world, Blister Coating is important nowadays. Without this method, every packing got a little bit tough. Many reputed companies in this world use this technique most of the time.
