Externally, the bubble wrap film has the form of a web with round, air-containing cavities uniformly distributed over the surface. Bubbles perform excellent cushioning functions. The air inside such cavities provides effective thermal insulation. This contributes to the use of the material as a reliable insulation.
This packaging tool perfectly combines the standard properties of a conventional plastic film, which creates good protection against atmospheric phenomena. Along with this, the material has the ability to cushion under mechanical stress. This avoids damage to goods in the event of shock, vibration, shock.
The Secret to Bubble Film Success
The widest distribution of air-bubble packaging film was due to its excellent cushioning properties. Significantly reflected the growth in demand for material as a result of a constant increase in international trade.
In the case of moving goods over long distances and the need for their storage in large volumes, the bubble wrap film becomes simply an indispensable tool. If desired, it can transport the most fragile items, for example, crystal products.
Types
Depending on the thickness, the following types of bubble film are distinguished:
- Two-layer film - consists of a layer of smooth polyethylene and air-containing bubbles.
- Three-layer film - has the form of two layers of polyethylene and bubbles placed between them.
The three-layer bubble wrap film is a denser and more durable material compared to the two-layer type of packaging base. An increase in the density index directly affects the possibility of transporting fragile goods packaged in film.
Material structure
Bubble packaging film has a truly unique structure. Each individual bubble is actually an individual, separate sphere. That is why when a single bubble ruptures, the surrounding structural elements remain unharmed.
The presence of protection in the form of a sufficiently strong external polyethylene layer protects the fragile bubbles from damage. An especially strong structure is distinguished by a three-layer bubble wrap antistatic film, which can be used for reusable use.
Strength
You can measure the strength of a bubble film based on its grammar. This refers to the amount of polyethylene in grams that was required to produce a square meter of material.
The increase in a significant amount of polyethylene per square during manufacture leads to an increase in the density index. Based on this, the bubble wrap film gains the ability to counteract certain loads. The height of the bubbles also has a certain value. The higher the bubbles, the less likely the damage to goods.
Application
The range of possible applications of the bubble film is wide enough. Currently, the material is actively used in packaging:
- furniture;
- electronics and fragile expensive equipment;
- automotive parts;
- dishes, glass, mirrors, porcelain, other fragile materials;
- optics;
- carpentry ;
- antiques, jewelry;
- shoes;
- lighting products.
Among other things, the material can be used as heat, noise and moisture insulation during construction and repair work.
If we talk about the domestic use of bubble wrap, then it is worth noting the possibility of its use as rugs and curtains in bathrooms, a material for protecting cars from the effects of weather phenomena. The described packaging material (bubble wrap) is often used as a protective blanket for swimming pools and hotbeds.
To organize a relatively modest home move, it will be sufficient to buy a small roll of bubble wrap with a footage of about 10 m. When using the material in warehouses, it is recommended to purchase it with rolls with a maximum footage. The acquisition of large quantities of packaging material is more profitable. An increase in the footage of the film upon purchase leads to a decrease in cost per linear meter.
Benefits
Among the main advantages of air bubble films it should be noted:
- Possibility of efficient operation in the widest temperature range.
- High strength under mechanical stress.
- Ideal shock absorbing performance.
- Good tensile strength.
- Almost imperceptible weight with significant volumes of material.
- The possibility of saving free space due to the high elasticity of the material.
- Absolute safety, the absence of components harmful to human health and the environment.
- The possibility of reuse with careful use of the film for its intended purpose.
- The absence of toxic and chemical substances that are capable of changing the properties of packaged products.
- Possibility of application for packaging food products.
- The material protects goods from exposure to elevated and lowered temperatures tens of times more effective than conventional plastic film.
