A common question that appears is where to buy bubble wrap. Bubble wrap isn’t the most accessible product to find, but there is no place like the manufacturer to get a good bang for your buck. Another question that arises a lot is why the diameters of the bubble rolls vary. This diameter depends on the manufacturer and their process. It even occurs even when the stated linear meters are the same in some as in others.
So, why are rolls wider than others?
Apparently, the first idea that comes to mind is that we are being scammed with the meters that the roll brings. But, if the manufacturer assures them, it is not usually so. They will be within the tolerance in the specifications of the product.
The diameter of bubble plastic roll depends on three things:
- The thickness of the bubble film or the amount of air in the bubbles.
- The tension with which the roll is wound (the more tension the bubbles decrease their height slightly).
- Logically the same meters of the bubble paper roll.
The height of a standard bubble is about 4mm. The rolls of bubble film that are usually manufactured with this height of bubbles are about 100 or 150 meters. Approximate diameter of these coils would be 85cm.
Other topics to take into account
Touching another topic, we would like to talk about a fascinating issue. It turns out that a roll of about 85cm in diameter cannot pass through a frame of a standard door of our home. You can take a tape measure and check it. The width of a door is usually about 70 to 80cm. And if we talk about the doors of our cars, the width of a door of our vehicle can vary from about 65-75cm. This reason has made some manufacturers think that the 4mm can be reduced to 3mm. The truth is that this medium or a millimetre is hardly appreciated to the touch. Although, we do gain a lot by reducing the diameter keeping the same 150 linear meters of a roll.
I think that is a good answer for the curiosity regarding the difference in the diameters of the bubble wrap rolls from different manufacturers.
