Bubble wrap is the most widely used protective packaging material. Each bubble acts as an individual cushion that absorbs impacts without adding significant weight. If you ship fragile products—crockery, electronics, glass, ceramics—it is your best ally.
But using it incorrectly is almost worse than not using it at all. In this guide, we explain how to correctly place it, what bubble size to choose, and how much you need depending on what you're packing.
The bubbles go inwards (and almost no one does it right)
The most common mistake: putting the bubbles outwards. It looks nice, yes. But you lose half the protection.
The bubbles must touch the object. This way, each one acts as an individual mini-cushion that adapts to the surface. If you put them outwards, the object rests on a flat surface—which is basically like putting down a plastic sheet and little more.
The exception: if you are wrapping something with sharp corners that could pop the bubbles (like a metal frame), put the bubbles outwards so the corners don't puncture them.
Small bubble vs. large bubble: when to use each
| Type | Diameter | Protection | Ideal for |
|---|---|---|---|
| Small bubble (10 mm) | 10 mm | Fine cushioning, adapts to irregular shapes | Tableware, glasses, ceramics, cosmetics, small electronics |
| Large bubble (25-30 mm) | 25-30 mm | Absorbs strong impacts, covers large surfaces quickly | Screens, paintings, mirrors, appliances, furniture |
Small bubbles wrap better because they fold around complex shapes—a wine glass, a vase, a figurine. Large bubbles cover faster and absorb more powerful impacts—for a TV screen or a large mirror, there's no doubt.
If you have an e-commerce business and can only stock one size, small bubbles are more versatile. If you manage a warehouse with large products, large bubbles save you time.
How many layers do you need
Wrapping a book is not the same as wrapping a glass. Here's a reference:
| Object | Layers | Complement |
|---|---|---|
| Not very fragile (books, clothes, shoes) | 1 layer | None—just to prevent scratches |
| Standard fragile (tableware, ceramics, glass) | 2-3 layers | Kraft paper filler in gaps |
| Very fragile (fine glassware, electronics, instruments) | 3+ layers | Foam between pieces + filler + double wall box |
| Screens, paintings, mirrors | 2 layers (large bubble) | Corner protectors on corners + reinforced flat box |
The general rule: if you shake the closed box and hear something moving inside, there's not enough protection. The product must be completely immobilized.
How many meters you need
It depends on what you are packing, but here are some real-world references:
| Situation | Approx. meters |
|---|---|
| Small e-commerce shipment (1 item) | 0.5 m² |
| Standard move (tableware + fragile items) | 20-30 m² |
| Large move (entire house) | 40-60 m² |
| E-commerce warehouse (monthly stock) | Rolls of 50-100 m² |
At TeleCajas, we sell bubble wrap rolls from 10 m² for small shipments up to industrial rolls by the pallet. If you buy in bulk for your business, we have custom B2B prices.
Common mistakes that ruin packaging
Bubbles facing out. We've said it already, but it's worth repeating: the bubbles touch the object.
A single layer for everything. A plate wrapped with one layer of bubbles is a broken plate waiting to happen. At least two layers for anything fragile.
Not filling gaps. Bubble wrap protects against bumps, but if the object rattles around inside the box, the bubble wrap cannot do its job. Always fill with kraft paper or paper shreds.
Reusing old bubble wrap. If the bubbles are deflated, there's zero protection. Quality bubble wrap (high pressure, like TeleCajas') lasts much longer, but once the bubbles are popped, it's time for a new roll.
Is bubble wrap recyclable?
Yes. It is low-density polyethylene (LDPE, code 4), recyclable in the yellow container. It can also be reused several times if it is in good condition. If you are looking for more ecological alternatives for filling, crinkled kraft paper and paper shreds are biodegradable. More options in our guide to ecological and sustainable packaging.
Frequently asked questions about bubble wrap
How is bubble wrap applied?
With the bubbles touching the object and the smooth side outwards. Each piece is wrapped individually, secured with adhesive tape or film, and placed inside the box with filler material in the gaps. For fragile items, a minimum of 2 layers. At TeleCajas, they have a step-by-step guide for packing fragile products.
Small or large bubble for shipping?
Small bubble (10 mm) for small and delicate items such as tableware, cosmetics, and electronics. Large bubble (25-30 mm) for large items such as screens, paintings, and appliances. If you can only have one size, small bubble is more versatile.
How much bubble wrap do I need for a move?
For a 2-bedroom apartment, about 20-30 m² will cover tableware, glassware, and fragile items. For a large house, 40-60 m². TeleCajas' moving packs already include enough bubble wrap for the fragile items in the pack.
Does bubble wrap protect against moisture?
Partially. It is impermeable to liquid water, so it protects against splashes. But it is not a barrier against ambient humidity—if you need protection against prolonged humidity (storage in a storage unit, maritime shipping), combine it with desiccant bags or stretch film.
Where to buy bubble wrap in Spain?
At TeleCajas, they have high-pressure bubble wrap rolls manufactured in Spain. From 10 m² to industrial rolls. 24-hour shipping, no minimum order, prices with VAT included. For large volumes, factory prices by the pallet.
