Bubble plastic, commonly known as bubble wrap, is a flexible plastic sheeting containing numerous small air pockets. It is widely used as a cushioning material for packaging delicate items during shipment. Bubble plastic is lightweight, water-resistant, reusable, and non-scratching, making it an ideal protective packaging solution.
Key Facts
- Bubble plastic is made from tiny beads of resin, usually polyethylene, with different properties[3].
- The resin beads are melted down together at high temperatures, typically over 450 degrees Celsius, until they combine and form a thin film.
- The film is then flattened to the desired thickness before being fed through rollers with small holes[3].
- As the film passes over these rollers, air is vacuumed onto it, pushing it into the small holes and creating the characteristic air bubbles[3].
- The film with the air bubbles is then run across more rollers, which seal it with another layer of film, trapping the air inside and ensuring that the bubbles stay contained.
- Finally, the bubble plastic is cut to the desired width and perforated so that it can be rolled up into large, industrial-sized rolls for shipping.
Manufacturing Process of Bubble Plastic
The manufacturing process of bubble plastic involves several key steps:
-
Raw Material Preparation
Bubble plastic is made from tiny beads of resin, typically polyethylene, with different properties (Stanley Packaging, 2015).
-
Resin Melting
The resin beads are melted down together at high temperatures, typically over 450 degrees Celsius, until they combine and form a thin film (Rajapack, 2018).
-
Film Flattening
The molten film is then flattened to the desired thickness using rollers (Stanley Packaging, 2015).
-
Bubble Formation
The flattened film is fed through rollers with small holes. As the film passes over these rollers, air is vacuumed onto it, pushing it into the small holes and creating the characteristic air bubbles (Rajapack, 2018).
-
Film Sealing
The film with the air bubbles is then run across more rollers, which seal it with another layer of film, trapping the air inside and ensuring that the bubbles stay contained (Stanley Packaging, 2015).
-
Cutting and Perforation
Finally, the bubble plastic is cut to the desired width and perforated so that it can be rolled up into large, industrial-sized rolls for shipping (Stanley Packaging, 2015).
Customization of Bubble Plastic
The bubble plastic manufacturing process allows for customization in terms of length, perforations, bubble size, and even the color and shape of the bubbles (Katzke Packaging Co., 2021). This versatility makes bubble plastic suitable for a wide range of packaging applications.
Conclusion
Bubble plastic is a versatile and widely used packaging material that provides excellent protection for delicate items during shipment. Its manufacturing process involves several key steps, including raw material preparation, resin melting, film flattening, bubble formation, film sealing, and cutting and perforation. The ability to customize bubble plastic makes it an ideal solution for various packaging needs.
