Glass Boston Round Bottles
The Boston Round bottle, also known as a Winchester bottle, is distinctive in its classic shape. Characteristic of the Boston Round are its round body, rounded shoulders, and narrow screw neck opening. Made of glass, these bottles are traditionally used for pharmaceutical, chemical and laboratory applications. Popular uses also include essential oils, e-liquids, fragrances and other liquids.
Key benefits:
- Virtually inert and impermeable, glass is the most stable packaging material
- High chemical resistance levels
- Extremely high resistance to heat and cold
- High clarity, the amber and blue colors provide UV protection for light-sensitive products.
Available in a variety of neck sizes. The first number refers to the diameter (in mm), and the second refers to the closure depth, style and thread. Pair with a variety of closures including Dropper Assemblies (71829), Applicator Caps (71810-71812), Screw On Caps (71824), Phenolic Caps (71825), Fine Mist Sprayers (71820), and Treatment Pumps (71822).
Boston Round bottles are also available in LDPE (72210), HDPE (72219) and PET (72220). See our HDPE or PET Guide to help decide which is right for your packaging needs.
HDPE or PET Plastic Bottle, which one is More Suitable for Pharmaceutical Packaging? The choice between HDPE (High-Density Polyethylene) and PET (Polyethylene Terephthalate) for pharmaceutical packaging is a complex decision that depends on several factors, such as the type of medication, shelf life, storage conditions, and environmental concerns. Here’s a breakdown of the considerations for each material: |
HDPE Bottles in Pharmaceutical Packaging Advantages: Chemical Resistance: HDPE is known for its resistance to many chemicals, which makes it ideal for certain types of medications.Temperature Resistance: HDPE can withstand higher temperatures, which is beneficial if the pharmaceuticals require sterilization. Opaque: HDPE’s opacity can protect light-sensitive medications from deterioration. Moisture Barrier: Provides good protection against moisture, especially important for hygroscopic substances.
Disadvantages: |
PET Bottles in Pharmaceutical Packaging Advantages: Clarity: PET bottles are transparent, which allows for easy inspection of the medication.Gas Barrier: PET has better barrier properties against gases, thus preserving the efficacy of the medication for a longer time. Recyclability: PET is widely recycled and can be reprocessed more easily compared to HDPE. Lightweight: PET bottles are generally lighter than HDPE bottles, which can reduce shipping costs.
Disadvantages: |
Final Verdict For Light-Sensitive Medications: HDPE might be the preferred option due to its opacity. For Oxygen-Sensitive Medications: PET might be more suitable due to its lower gas permeability.For High-Temperature Sterilization: HDPE might be the better option. For Environmental Concerns: PET’s higher recyclability may make it more suitable if this is a key consideration. Ultimately, the choice between HDPE and PET for pharmaceutical packaging will depend on the specific requirements of the medication in question, cost considerations, and the manufacturer’s focus on sustainability. |
