The ABCs of Plastic Effervescent Tablet Tubes: Your Quick Guide

1. What are effervescent tablet packaging?

Effervescent tablet packaging is specifically designed to protect effervescent tablets from moisture, light, and air, all of which can degrade the product and reduce its effectiveness. Effervescent tablets typically contain an active ingredient along with an acid and a base, which react when they come into contact with water, leading to the effervescent effect. Due to this reactive nature, such tablets require special packaging considerations. Here are some commonly used packaging solutions for effervescent tablets:

Plastic Tubes

  • Material: Often made from high-density polyethylene (HDPE) or polypropylene (PP).
  • Features: Air-tight, moisture-resistant, and often equipped with a desiccant cap.
  • Use: Ideal for home use and long-term storage.

Aluminum Tubes

  • Material: Made from aluminum which offers excellent protection against moisture and light.
  • Features: Often come with a membrane seal under the cap for added protection.
  • Use: Commonly used in pharmaceutical applications.

Strip Packaging

  • Material: Typically a combination of aluminum and plastic or paper.
  • Features: Individual sections for each tablet, which are torn or popped open.
  • Use: Convenient for on-the-go scenarios but not ideal for long-term storage.

Blister Packs

  • Material: Often use PVC or PET plastic along with aluminum foil backing.
  • Features: Each tablet is individually sealed, offering good protection.
  • Use: Common in pharmaceutical and over-the-counter products for consumer convenience.

Glass Jars

  • Material: Made from glass which is excellent at blocking moisture but can be heavy and breakable.
  • Features: Often come with air-tight lids and may include a layer of protective material like cotton.
  • Use: Less common due to fragility but used for some high-end or specialty products.

Sachet Packs

  • Material: Generally made from multi-layer materials including aluminum foil, PE, and sometimes paper.
  • Features: Usually contains a single tablet, sealed to keep out moisture.
  • Use: Ideal for sample distribution, travel packs, or single-use scenarios.


  • Material: Often made from laminated materials that include layers of aluminum and plastic.
  • Features: Zip-lock or heat-sealed tops make them resealable.
  • Use: Typically used for bulk packaging or for institutional use.

These Have the Special Features

  • Desiccants: To absorb any moisture, some packages include a desiccant pod or sachet.
  • Child-Resistant Caps: For safety reasons, many packaging options come with child-resistant features.
  • Information Labels: Important information such as usage directions, ingredients, and expiry dates are usually printed on the package or included as a leaflet.

Understanding the features and uses of each type of packaging can help you make an informed choice, whether you’re a manufacturer looking for the best way to package your product or a consumer seeking to store your effervescent tablets effectively.Let’s delve into the details of plastic effervescent tube packaging.

2. How is the structure of a Plastic Effervescent Tablet Tubes designed?

An effervescent tube comprises a plastic tube and a desiccant cap. The desiccant cap contains a desiccant canister, along with a spiral spring.

3. What is the material of the plastic effervescent tube with desiccant cap?

The primary materials used for effervescent tube packaging are polypropylene (PP) and polyethylene (PE).

The tube is made of polypropylene, which is a semi-crystalline thermoplastic. It exhibits high impact resistance, strong mechanical properties, and resistance to various organic solvents and acid-base corrosion. Its appearance is similar to polyethylene but it’s lighter, more transparent, odorless, non-toxic, and has excellent moisture resistance. It can prevent odors from permeating and has high heat resistance, remaining undamaged even after being sterilized in steam at 135°C for 100 hours.

The cap is made of polyethylene. Polyethylene is non-toxic, hygienic, and cost-effective. It boasts good flexibility, and its transparency varies with molecular weight. It has excellent moisture resistance, is easy to process and shape, and possesses great heat-sealing and thermal bonding properties. Additionally, it demonstrates strong cold resistance.

4. What are the characteristics of the plastic effervescent tablet packaging?

The characteristics of the effervescent tube are mainly manifested in the desiccant cap:

  • A tamper-evident band is set on the desiccant cap, and a bottle buckle is placed at the neck of the bottle. When the cap is closed, the tamper-evident band gets caught by the bottle buckle. Upon opening, the tamper-evident band automatically detaches, serving as an anti-tampering measure.
  • A spiral spring is incorporated into the cap to secure the medication. This prevents the drugs from breaking due to jostling during transportation.
  • A small canister is integrated into the cap of the effervescent tube, containing a desiccant. The separation of the desiccant and the medication ensures the safety of the drugs and prevents them from getting damp, thereby preserving the quality of the medication.

5. Applications of plastic effervescent tablet tube?

Plastic effervescent tubes find extensive applications in the pharmaceutical and healthcare industries, primarily for storing and safeguarding various types of effervescent tablets. These tablets may encompass medications, vitamins, mineral supplements, and more. Here are some key applications:

Medical Applications

  1. Antipyretics and Analgesics: Such as effervescent aspirin or other antipyretic and analgesic medications.
  2. Antacids and Gastric Medications: Effervescent tablets used to treat conditions like excess stomach acid or indigestion.
  3. Anti-Inflammatories: Used in oral or other inflammatory conditions.
  4. Antibiotics and Disinfectants: Especially for oral or skin disinfection purposes.
  5. Respiratory Medications: Effervescent tablets used to relieve cough or nasal congestion.

Healthcare Applications

  1. Vitamin Supplements: Common examples include effervescent vitamin C, vitamin D, and B-complex vitamins.
  2. Minerals and Electrolytes: Effervescent tablets containing minerals like calcium, magnesium, and potassium, commonly used for electrolyte replenishment during exercise or in hot environments.
  3. Energy Supplements: Typically containing caffeine and other energizing ingredients.
  4. Antioxidants: Effervescent tablets rich in antioxidants, such as those containing tea polyphenols or other plant extracts.

The sealing cap of effervescent tubes serves multiple vital functions, primarily aimed at preserving the effectiveness and stability of effervescent tablets. This specially designed cap provides an airtight environment, blocking the entry of air and moisture, thereby safeguarding the effervescent tablets from dampness and oxidation. Some sealing caps even feature embedded desiccants or silica gel packets to absorb any residual moisture within the tube. Additionally, many of these caps are designed to be child-resistant, enhancing the safety of product usage.Such sealing caps not only extend the shelf life of effervescent tablets but also offer convenience and a secure user experience.

8. Types of Closure for Effervescent Tubes?

Our product portfolio encompasses various crimp-sealed closures with integrated desiccants, with or without tamper-evident features, and the option of having a spiral spring or not.
