How to Store HDPE Bottles to Reduce Risk and Expense

When you utilize plastic packaging for your pharmaceutical, nutraceutical, or lifestyle product, it’s crucial to know how to store the bottles before filling them. Proper storage will help protect you, your product, and your customers.

Why Proper Storage is Important

HDPE bottles require proper storage and care. Correct storage procedures ensure that the bottles will perform correctly with the product inside. Proper storage helps:

  • Maximize the integrity and lifespan of HDPE bottles
  • Protect the product in the bottle
  • Reduce risk for you, your business, and your customers
  • Maintain customer loyalty in your brand
  • Protect your business’ profitability and bottom line

Maintain Proper Storage Conditions

Bottle storage conditions such as time, temperature, and humidity can have a significant impact on HDPE plastic bottles. The exposure and age of a sample can also affect the shrinkage, impact properties, and stress crack resistance of the container.

Here are some important storage considerations for your HDPE bottles:

Storage Time

The storage time of unfilled HDPE bottles should be minimal. Maintain a strict first-in-first-out inventory. Many end-users will re-approve bottles after two or three years of storage.

Storage Temperature

Elevated storage temperatures cause HDPE containers to shrink, and harsh conditions can cause severe distortion. The degree of distortion and shrinkage depends on the bottle design and storage conditions. Higher storage temperatures also accelerate the aging process of the container.White HDPE plastic pill bottles from Drug Plastics

Provide moderate storage temperatures to ensure consistent bottle dimensions and properties. It is routinely reported that HDPE bottles can withstand temperatures of 110°F for brief periods.

Humid Storage Conditions

Although humidity itself will not degrade the HDPE container, a humid environment can have a direct impact on secondary packaging such as cardboard cartons. Use stretch wrap and/or control warehouse conditions to alleviate secondary packaging problems.

Surface Contamination

Keep HDPE bottles as clean as possible. It is best to leave them in original sealed cartons. Your storage area should be clean, dry, and dust, odor, insect, and rodent-free.
