How to Store Empty Bottles and Jars Without Damage or Degradation

1. Keep containers out of direct sunlight - UV exposure gradually yellows and weakens most plastics over time, and can fade colored glass as well. Store containers away from windows or skylights, or under an opaque cover, even during short-term storage, since the damage accumulates with total exposure time, not just intense heat.
2. Store in a temperature-stable area, away from extreme heat or cold - Repeated temperature swings can cause some plastics to become brittle over time and can affect how well a cap's liner continues to seal. A stable, moderate storage temperature preserves both the container and any pre-applied closures better than a space that swings between hot and cold.
3. Respect stacking weight limits, even for empty containers - Empty containers can still deform under excessive stacked weight, particularly thinner-walled plastic bottles near the bottom of a tall stack. Follow any stacking guidance for your specific container, and avoid stacking mixed sizes and shapes that don't distribute weight evenly.


4. Store caps separately from bottles when possible for long-term storage - A cap left threaded onto an empty bottle for an extended period can develop a liner that compresses unevenly or partially adheres to the bottle's finish. For inventory that will sit unused for months, storing caps and bottles separately, then reassembling at fill time, helps preserve both.
5. Keep containers away from strong-smelling chemicals or solvents in storage - Plastic containers in particular can absorb ambient odors from nearby stored chemicals, cleaning products, or solvents, which can transfer into a product filled later.
6. Rotate older inventory to the front and use it first - A simple first-in, first-out system for stored containers means nothing sits in storage indefinitely, limiting how much cumulative UV, temperature, and stacking exposure any single batch of inventory experiences before it's actually used.

How to Store Empty Bottles and Jars Without Damage or Degradation FAQ

Storing empty bottles and jars properly means limiting UV exposure, respecting stacking weight limits, and rotating older inventory so nothing degrades unnoticed before it's used.

Does Sunlight Really Damage Empty Plastic Bottles?

Yes - UV exposure gradually yellows and weakens most plastics over time, and the damage accumulates with total exposure time even without intense heat.

Should I Leave Caps On Bottles During Long-Term Storage?

For inventory sitting unused for months, storing caps and bottles separately helps prevent a liner from compressing unevenly or partially adhering to the bottle's finish.

Can Stacking Empty Containers Actually Damage Them?

Yes - thinner-walled plastic bottles near the bottom of a tall stack can deform under excessive weight, even when the containers themselves are empty.

Can Stored Containers Pick Up Odors From Nearby Chemicals?

Yes - plastic containers in particular can absorb ambient odors from nearby chemicals or solvents in storage, which can transfer into a product filled later.

What's the Best System for Rotating Stored Inventory?

A simple first-in, first-out approach, using older stock before newer stock, limits how much cumulative exposure any single batch of containers experiences before use.
