PET Cylinder Bottles

PET Cylinder bottles are designed with a square shoulder and flat base. Its straight and simple profile makes it a standard choice for packaging liquid products in many industries including health and beauty, food, nutraceuticals, pharmaceuticals and more. Slim option available, the perfect choice when you have tight spaces, or want to get more product on the shelf.

Key benefits:

  • Made of polyethylene terephthalate (PET) plastic
  • PET plastic offers high impact and scratch resistance
  • Lightweight
  • Glasslike clarity is ideal for displaying your product
  • Classic straight profile is ideal for a variety of products
  • Amber, blue and green 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 Flip Spout Caps (71814), Disc Top Caps (71815), Yorker Spout Caps (71816), Dropper Tips (71817), Dispensing Pumps (71819), Fine Mist Sprayers (71820), Treatment Pumps (71822) and Screw On Caps (71824).

Polyethylene terephthalate (PET) is marked with the resin identification code of 1. PET is of the polyester family and has high clarity, good chemical resistance, high impact resistance, and medium rigidity. PET is also light-weight and is used for products containing essential oils.

Avoid using PET containers to store products that contain essential oils greater than 5% or fragrance oils greater than 15%. If your oil percentages exceed these respective levels, please consider using glass (72011).

Cylinder bottles are also available in HDPE (72211) and LDPE (72221). 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:
Gas Permeability: HDPE is more permeable to gases like oxygen, which could be a concern for medications that are sensitive to oxidation.
Environmental Impact: While HDPE is recyclable, the rates of recycling are generally lower than that for PET.

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:
Temperature Sensitivity: PET bottles are generally not as heat-resistant as HDPE, which might not make them suitable for medications that require high-temperature sterilization.
Cost: PET can be more expensive than HDPE, which could be a factor depending on the scale of production.

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.
