Packaging for Tablets: Blister vs Jar vs Tube (and When to Choose Each)
Tablet packaging is not only a branding decision. The choice between blisters, jars or tubes directly affects product stability, shelf life, user experience and manufacturing efficiency. This article explains when each tablet packaging format is typically used in food supplement manufacturing and how CMOs approach packaging selection.
In food supplement manufacturing, tablet packaging plays a critical role in protecting product quality from production to consumer use. While tablets are generally more stable than capsules or powders, they remain sensitive to moisture, mechanical stress and repeated handling.
For CMO, packaging selection is evaluated alongside formulation behaviour, tablet geometry and target market requirements. Choosing the wrong packaging format can lead to stability issues, consumer complaints or unnecessary cost.

Why tablet packaging matters in manufacturing
Tablet packaging affects:
Moisture exposure
Mechanical protection
Dosing convenience
Shelf life
Logistics efficiency
From a manufacturing perspective, packaging decisions influence not only the final product but also line configuration, throughput and quality control.
Blister packaging: individual protection and compliance
WHAT IS BLISTER PACKAGING?
Blister packaging encloses tablets individually in formed cavities, typically sealed with aluminium or laminated foil. Each tablet remains isolated from external exposure until use.

When blisters are typically used
Blister packaging is commonly selected when:
- Moisture protection is critical
- Precise daily dosing is required
- Regulatory or retail presentation is important
- Products are sold through pharmacies
Typical causes of high friability.
- Vitamins and minerals
- Multivitamin tablets
- Premium or regulated markets
Manufacturing advantages of blisters
From a CMO perspective, blisters offer:
- Strong moisture and oxygen barriers
- Reduced risk of tablet abrasion
- Clear batch traceability
- Professional retail presentation
Jar packaging: flexibility and cost efficiency
WHAT IS JAR PACKAGING?
Jar packaging involves filling multiple tablets into bottles or jars, typically made of plastic or glass, often combined with desiccants.

When jars are typically used
Blister packaging is commonly selected when:
Jars are commonly selected when:
- Products are used daily over longer periods
- High tablet counts are required
- Cost efficiency is a priority
- Flexibility in tablet size is needed
Typical applications include:
- Mineral supplements
- Amino acid tablets
- Sports nutrition products
Limitations of jar packaging
Because jars are opened repeatedly:
- Tablets are exposed to moisture and air
- Abrasion and dusting risk increases
- Desiccant management becomes critical
Tube packaging: the standard for effervescent tablets
WHAT IS TUBE PACKAGING?
Tube packaging typically consists of cylindrical containers with integrated or loose desiccants. Tablets are stacked vertically and protected from moisture.
- When tubes are typically usedTube packaging is primarily selected for:
- Effervescent tablets
- Moisture-sensitive formulations
- Products intended for dissolution in water
- Effervescent tablets are rarely packaged outside tubes due to their sensitivity.
Packaging and tablet defects
Packaging choice can directly influence:
- Dusting in amino acid tablets (more common in jars)
- Chipping during transport (reduced in blisters)
- Moisture-related degradation (critical for effervescent)
FAQ: Tablet Packaging in Food Supplement Manufacturing
In some cases, yes. However, changing packaging may affect tablet stability and performance, especially for moisture-sensitive formulations. Packaging changes usually require technical evaluation.
Effervescent tablets are highly sensitive to moisture. Tube packaging with desiccants provides controlled internal humidity, which is difficult to achieve with jars or blisters.
Not always, but desiccants are commonly used in jar packaging to reduce moisture exposure, particularly for hygroscopic or abrasion-prone tablets.
Blister packaging typically involves higher tooling and line setup costs. However, it can reduce damage, improve shelf life and support premium positioning, which may offset costs.
Packaging selection is part of early feasibility assessment, considering formulation behavior, tablet geometry, stability requirements and market expectations.
