New vs. Long-Stored Bubble Wrap: What’s the Difference?
Bubble wrap may look like a simple packaging material that can be stored for a long time. However, storage duration, temperature, sunlight, and environmental conditions can gradually affect the film and air bubbles.
So, if you have two rolls of bubble wrap, how can you tell whether they are still in good condition?
1. Check the Firmness of the Bubbles
One of the easiest things to check is the air inside the bubbles.
Newly produced bubble wrap that has been stored properly should have consistent, firm bubbles. When gently pressed, the bubbles should provide noticeable resistance.
Bubble wrap that has been stored for a long period, especially under unsuitable conditions, may develop softer or partially deflated bubbles. This can reduce its cushioning performance.
2. Check the Strength and Flexibility of the Film
Bubble wrap in good condition should remain flexible and resistant to tearing.
Long-term exposure to heat or direct sunlight may accelerate the deterioration of plastic film. Over time, the film may become stiffer, more brittle, or easier to tear.
Before using older stock, gently stretch or handle a small section to check whether the film still feels strong and flexible.
3. Check Bubble Consistency Across the Roll
Do not inspect only the outside of the roll.
Unroll a section and check whether the bubbles remain consistent across different areas of the sheet.
If many bubbles are soft, flat, or noticeably deflated, the material may no longer provide the same level of cushioning as bubble wrap in better condition.
4. Look for Changes in Appearance
Clear bubble wrap may change in appearance when exposed to unsuitable storage conditions for extended periods.
For example, prolonged exposure to sunlight or high temperatures may cause changes in color or film appearance.
However, color alone should not be used to determine the age or quality of bubble wrap, because clarity and color can also vary depending on the raw materials and manufacturing formula.
5. Storage Conditions Matter More Than Age Alone
Older bubble wrap that has been stored properly may remain in better condition than newer bubble wrap that has been exposed to direct sunlight or excessive heat.
For better storage, bubble wrap should be kept:
- Away from direct sunlight
- Away from high temperatures and heat sources
- In a dry, suitable environment
- Protected from dust and contamination
- Without heavy objects placed on top of the rolls
Proper storage can help maintain the condition of both the film and the air bubbles for longer.
Can Old Bubble Wrap Still Be Used?
Yes, as long as the bubbles and film are still in good condition.
“Old” does not automatically mean unusable.
Before using long-stored bubble wrap, check the bubble firmness, film flexibility, and overall cushioning performance.
For fragile, sensitive, or high-value products, if a significant number of bubbles have deflated or the film has become brittle, using bubble wrap in better condition may provide more reliable protection.
New Bubble Wrap Cannot Be Identified by Appearance Alone
The difference between newly produced and long-stored bubble wrap should be evaluated based on bubble firmness, film strength, consistency, and storage conditions, rather than appearance alone.
For online sellers, wholesalers, factories, and businesses that regularly use packaging materials, proper inventory rotation and storage can help maintain bubble wrap performance until it is ready to be used.
PackBros is a manufacturer of bubble wrap and bubble mailers in Thailand. We manufacture our own bubble wrap and control the production process and product quality to provide consistent bubbles, strong film, and reliable cushioning for packaging and shipping applications.
FAQ
Can bubble wrap still be used after being stored for a long time?
Yes. If the bubbles remain firm, the film remains strong and flexible, and there are no significant signs of deterioration, the bubble wrap may still be suitable for use.
Can bubble wrap lose air over time?
Yes. Some bubbles may gradually lose air over time. The rate can vary depending on the material, manufacturing process, storage duration, and environmental conditions.
Is it okay to store bubble wrap in a hot warehouse?
Excessive heat and direct sunlight should be avoided because they may accelerate the deterioration of plastic film.
Does yellow bubble wrap mean it is old?
Not necessarily. The color and clarity of bubble wrap can also depend on the raw materials and manufacturing formula, so color alone is not a reliable indicator of age.
What should I check before using long-stored bubble wrap?
Unroll a section and inspect several areas. Check the firmness and consistency of the bubbles, the strength and flexibility of the film, and whether the material still provides adequate cushioning.
