ZONESUN vial and ampoule labeling machines achieve precise single-sided, and wrap-around labeling on small containers such as crimped vials, sample vials, test vials and ampoules.Because these bottles are typically small in diameter and lightweight, labeling them requires specialized equipment to ensure accuracy, stability, and efficiency.
Vials & Ampoules' Characteristics
Crimpied Vials
Crimped vials are widely used in pharmaceutical packaging for vaccines, injectables, and lyophilized powder injections. Common diameters range from 16-30mm, suitable for 2-20ml filling volumes. They require higher labeling accuracy & speed.
Laboratory Vials
Laboratory vials are commonly used to store chemical reagents, biological samples, or test solutions. They usually lack a stable base, and caps larger than the vial diameter are common. The labeling process requires a highly stable conveyor system, which often needs to be customized to handle these vials.
Perfume Sample Vials
These sample vials are commonly used in the cosmetics, essential oil and perfume industries. Same as labortary vials, vial diameter is too small to keep upright. Automated vials feeding and conveying stability is important during labeling.
General Small Vials
These vials, small and cylindrical, are commonly used for liquid supplements. Depending on production needs, they can be labeled with horizontal, three-roller, side-belt, or other labeling systems. Bottle feeding units vary from timing screw to hopper feeding.
Glass Ampoules
Ampoules typically have an unstable base, sealed necks and fragile glass bodies which make them more difficult to handle during labeling.They are very common in pharmaceutical and cosmetics industries.Same as laboratory vials and perfume sample vials, they are using horizontal labeling to achieve precise and faster labeling.
Different Labeling Systems For Vials & Ampoules
Side-belt Labeling System
Side-belt labeling machines are commonly used for single-side labeling on upright bottles. Two vertical side belts hold the bottle firmly to ensure stable conveying, label adheres smoothly to the surface due to the pressure from pressing sponge.
Advantages
- Suitable for small upright bottles
- Short labels will be better
- Good labeling speed
- Simple structure and stable operation
Application
Crimped vials, essential oil vials etc
Three Roller Labeling System
Three-roller labeling machines are designed for wrap-around labeling on small cylindrical bottles. The bottle rotates between three rollers while the label is applied.
Advantages
- Suitable for small upright bottles
- Suitable for full-wrap labels
- Long labels has higher accuracy
- Stable bottle rotation
- Ideal for medium-speed production (about 20–40 bottles/min)
Application
Crimped vials, essential oil vials etc
Horizontal Labeling System
Horizontal labeling machines are used for small bottles that cannot stand upright, such as ampoules or perfume sample vials.Bottles are fed horizontally and rotate along rollers during labeling, which improves bottle conveying stability and labeling accuracy.
Advantages
- Suitable for non-freestanding bottles or cylindrical products
- Prevents bottle tipping or overlapping
- Customizable bottle feeding structure
- Short labels will be better
- Higher labeling speed
Application
Crimped vials, ampoules, perfume sample vials, blood sample vials, test tube, dental whitening gel pens, syringes
Star Wheel Labeling System
Star wheel labeling machines are typically used for high-speed production lines of upright bottles. The star wheel can firmly hold and precisely position each bottle during the labeling process. Bottle rotates between rollers while the label is applied.
Advantages
- Ideal for upright bottles
- High labeling speed
- High labeling accuracy
- Good for single side, double-sided and wrap-around labeling
- Accurate bottle positioning
Application
Crimped vials, essential oil vials, general small upright vials
Frequently Asked Questions
What types of bottles can vial labeling machines handle?
Vial labeling machines are suitable for small cylindrical containers including upright vials or non-freestanding vials such as crimped vials, laboratory sample vials, perfume sample bottles, and small liquid supplement bottles.
What labeling types are available for vials?
Common labeling types include single-side labeling, wrap-around labeling.
How accurate is vial labeling?
Most automatic vial labeling machines can achieve labeling accuracy within ±1 mm, depending on the bottle size and machine configuration.
Can the machine handle very small bottles?
Yes. Horizontal labeling machines are specifically designed for very small bottles that cannot stand upright.
What is the typical labeling speed?
Labeling speed varies depending on the machine type and label size. Some lhigh speed labeling system for small vials with short labels can reach 100BPM
Can labeling machines be integrated with other equipment?
Yes. Labeling machines can be connected with filling machines, capping machines, and other packaging equipment to form a complete production line.
What bottle feeding systems are available?
Bottle feeding systems include timing screw feeders and hopper feeders.
Can the machine handle different bottle sizes?
Most labeling machines allow adjustments for vials with smilar diameter and shape.When bottles differ greatly in size and shape, different labeling equipment may be needed.
What materials can be labeled?
Most of vial labeling machines can apply self-adhesive labels.
Can the machine be customized?
Yes. Labeling machines can be customized based on bottle size, label width and height, labeling speed, and automation requirements.
