How is bubble wrap made?

Bubble wrap is a fantastic material that is designed for protection against damage. The bubbles are incredibly fun to pop with your hands too, and bubble wrap is loved by many throughout the UK. Not many people know how a large bubble wrap roll is produced, however, and it is a technical process performed by professionals and machinery.



  • The material that extra strong bubble wrap is made from contains many different tiny beads of resin, which are combined to produce the material that we commonly use for bubble wrap. It is a polythene material, which is waterproof. It is see-through, and often quite heavy duty meaning it will not tear or rip easily.

  • These tiny resin beads are melted down together, at over 450 degrees Celsius, which forces them to combine to form the basic material that we use for the base layer of the bubble wrap, which is a thin film. This film is next flattened, to the desired thickness that we want the bubble wrap for packing UK to be. It can differ from different manufacturers.

  • Next, this thin film is passed through some large rollers, which have many small holes on. As the film travels over the rollers, the air is vacuumed into it, pushing it into the small holes on the rollers, which will form the air bubbles of the bubble wrap.

  • Once the air bubbles are pumped into the film, it is then passed onto some more rollers which put another layer of film over the air bubbles to seal the air inside. It means the air is contained and cannot escape.

  • Finally, it is cut to the desired width and perforated before it is rolled up onto industrial sized rolls and sold to businesses around the world.

Different sized bubbles are often used for different purposes, and each roller will differ in terms of sizes of bubbles that it produces. Larger bubbles require more material to surround them, and more work to pump the air inside too, which is why they are often slightly more expensive to buy than smaller ordinary sized high-quality bubble wrap.

Some bubble wraps have thicker material surrounding the air bubbles than others, and so they will be less easy to tear and rip. This determines the quality of bubble wrap, and it can differ from different manufacturers. It is important to try and test the different kinds to find what you want and need the most.

How much weight can you put into a cardboard box?

If you are moving home, it is often a common thing to wonder about and something that you need to consider, as to how much weight you can put into each of the house moving boxes . This will help you to determine which things can be put into boxes, and how many things you can put into each box too, and therefore help you to decide how many moving boxes online that you need and in which sizes. The weight will vary from box to box, and the type of box that you are using, plus the size of the box that you are using. Double walled packing boxes for moving are the strongest by far.
