Effervescent packaging

Simply put, effervescent packaging is a type of container used to store effervescent tablets.

They are characterized by tight seal integrity and closure because their main purpose is to protect the effervescent tablet from liquids.

Effervescent packaging has a wide range of applications including pharmaceutical and nutraceutical industries.

There are also many types, i.e., tubes, sachets, stick packs or blisters, etc. Each type is more appropriate to a specific application.

What Are Some Testing Guidelines For The Efficiency Of Effervescent Packaging?

Performing tests is important because it leaves you assured that the seal integrity and closure of the effervescent packaging is high.

This means the quality of packaged tablets are also high. Test the package for the following:-

  1. Loose fitting top.
  2. Unbounded seal area.

As said above, effervescent packaging are required if the expected lifespan of their contents is to be above 2 years.

Hence, the best testing method would be to store under severe temperature and humidity conditions similar to those they are expected to encounter.

This procedure is long term because they have to be stored for similar durations. It is also not practical and as such has to be simulated.

We simulate storage conditions by:-

  • Storing the effervescent packaging in test rooms regulated at constant elevated temperatures and humidity, g., 37 °C and 85% relative humidity.

We keep them in the test chambers for about three months. In order to pass the test, the packaging must show zero or little moisture pickup.

There are methods you could use to test the packaging that do not require as much time. Such methods are just as reliable because they assure product quality.

Examples include:

  1. Electronic air-tightness testing.
  2. Infrared seal testing.
  • Using detectable gases.
  1. Using detectable tracer materials.
  2. Vacuum under water testing. This is also the most efficient and common method.

What Advantages Should I Expect To Enjoy With Effervescent Packaging?

  • The effervescence packagings conform to GMP/ISO 15378 standards.

This means they have been subjected to thorough seal integrity tests and certified as highly effective and durable.

There Many Types Of Effervescent Packaging – What Are Some Examples?

Types of effervescent packaging include but aren’t limited to aluminum foils, blister packs, strip wraps, metal tubes, plastic tubes, glass tubes, etc.

Aluminum Foils

As the name suggests, they are made from Aluminium material.

They are light, flexible and are a barrier to water vapour and gases.

They are not susceptible to microbiological attacks and are nontoxic.

Moreover, they are good heat conductors, meaning you can heat seal them if your process requires so.

Aluminum tube

alluminum foil

Blister Packs

These require additional foil backing. Nonetheless, these thermoformed packagings are best suited for storing small diameter, relatively thick tablets which are hard.

They require a little pressure on the blister to remove the effervescent tablet from within the backing.

Blister packs

blister packs

Strip Wraps

Strip wrapping is done by hermetically sealing effervescent tablets in containers in pouches.

The pouches will keep them dry and uncontaminated until their time of use reaches.

They are usually packed into strips and stacked inside paperboard boxes.

Plastic Tubes

These are best suited for packaging effervescent tablets with low hygroscopicity order. This is because they are not as effective as metal or glass tubes.

Plastic packagings have significant moisture vapor permeability properties.

However, you can use them with special caps that contain silica gel or moisture-vapour absorbing dessicants.
