Bubble: Benefits & Strength



Bubble comes in two primary categories:

1.VOID FILL – filling in excess space around products in a box or container, protecting them against damage.

Typical applications:
– Shipping giftware
– Shipping books
– Shipping small appliances
– Shipping multiple items in the same container


2.BLOCKING & BRACING – securing products in a box or container to prevent them from shifting, sliding, moving, or colliding.

Typical applications:
– Shipping books
– Shipping jewelry
– Shipping fragile Items
– Shipping computer monitors
– Shipping precision gears
– Shipping sculptures
– Shipping Un-assembled furniture

These two categories go hand-in-hand as all empty space should be filled in order to block and brace effectively.

Pros of Bubble

✔ Comes in different sizes and film thicknesses.
✔ Comes in different forms like bags, sheets, and rolls.
✔ Offers protection against shock and vibration.
✔ Easy-to-use, reusable.
✔ Versatile: interleaving, wrapping, and cushioning.

Cons of Bubble

✘ Designed for short periods of use (days or weeks).
✘ Can be difficult to recycle (explained below).

The Use of Nylon Vs. 100% Polyethylene

Some bubble film companies use Nylon in their bubble manufacturing process. Nylon lowers the recycle number from a #4 to a #7 recycled product (where facilities exist), and also makes the bubble much less pliable. This lack of pliability, particularly evident when wrapping around corners or other sharp edges, causes some bubble products to puncture and tear much easier than products that are 100% polyethylene. With consumers becoming ever more aware of their environmental impact, but not wanting to sacrifice performance, a bubble product made with 100% polyethylene is the smartest choice.

How Do I Know Which Bubble is Best/Strongest?

Below is a graph detailing Polyair 1/2" Bubble against two Nationwide competitors. The bubble burst strengths were measured by observing the pounds of force needed to break the bubble.

5-10 tests were completed for each product. The averages are charted here:
