Customized 650mm HDPE Film Extrusion Line for Small-Scale Grocery Bag Manufacturing

The selection mainly depends on your product requirements. A single-layer blown film machine is sufficient for plain-color garbage bags and common supermarket bags with standard demands, featuring low investment and quick return. If you need films with high tensile strength, good toughness and special functions (e.g. heavy-duty handbags), or three-layer co-extrusion machine is recommended.

Key factors include the film width (wider width means higher price), automation level (equipped with IBC internal cooling system, automatic roll changing, etc.), brands of core components (such as motors and inverters), and die head configuration (rotary die head costs more).

Yes. Modern blown film machines have good adaptability to recycled materials. However, too high proportion of recycled materials may affect the strength and appearance of the film.

Yes. Biodegradable materials have special requirements for screw design and barrel temperature control, so dedicated screws and die heads are required.

The IBC internal cooling system realizes circulating cooling inside the film bubble, which can increase the output by more than 30% and improve film transparency and toughness. It is recommended for high-output production; it is optional for small startup machines based on your budget.
