What is a Inflation molding machine?

Inflation molding is a type of extrusion molding in which heat-melted resin is pressed against a mold with an opening and the part extruded from the opening is used as a product. The extrusion die has a ring-shaped opening, and the molten resin is extruded into a thin film. By blowing cooling air while extruding, it expands to a certain size and is formed into a bag shape. It is possible to mold not only single-layer films but also multilayer films at the same time.

Application of Inflation molding machine

It is used when making films such as food wrap films and plastic bags. It is also used to mold multi-layer olefin films to produce films used in agricultural houses, rice bags, fertilizer bags, general paint films, and food packaging films. It is possible to form high-performance films by adding additives such as pigments, antistatic agents, and AB agents that make it difficult for the film to stick to the product, to polyolefin-based materials such as polyethylene (PE) as well as vinyl chloride resin (PVC). I can do it.
