PE Air Bubble Film Machinery | 2/3/5/7-Layer Automatic Bubble Wrap Machines for Sale | China Manufacturers & Best Prices

air bubble sheet extruder machine(also named bubble wrap machine) is designed to produce air bubble films, which are widely used in packaging for shock absorption, cushioning, and insulation. Bubble wrap machines transform raw plastic materials into flexible sheets with evenly distributed air pockets, offering protection for fragile items during transportation and storage.

Air bubble film is a kind of packing material that has been widely used at present. it not only has a good cushioning effect. Shock resistance and heat-sealing performance. But also has such advantages as good corrosion resistance and transparency, etc. So it has been widely used for packing household wares, postal parcels, precision instruments, bicycles, polyurethane furniture, etc.

Bubble Film Raw Materials And Working Principle

Material Processing: Air bubble film extruder machine starts by melting raw materials such as LDPE (Low-Density Polyethylene), LLDPE (Linear Low-Density Polyethylene), or recycled plastics through an extruder.The molten plastic is then forced through a T-die to form a thin, continuous film. To enhance the aesthetic appeal of bubble film, color masterbatch can be added to the raw materials to change its color.

Air Injection: As the film exits the die, a vacuum forming roller creates air pockets (bubbles) by either suction or controlled air pressure. The bubble size (e.g., 6mm, 10mm, or custom) and density are adjustable based on production needs.
Cooling and Winding: The film is cooled using water or air to solidify the bubbles, then wound into rolls for further processing (e.g., cutting, laminating, or converting into bags).
