PE Breathable Film Line
Extrusion line for producing breathable film of baby diapers and sanitary napkins
Our PE breathable film line features our independently designed screws, known for excellent plasticizing quality, high wear resistance, and stable extrusion. The cast film line is equipped with a longitudinal multi-stage stretching system, allowing adjustable breathability as needed. Precise speed, pressure, and temperature control ensure uniform moisture permeability throughout the production process, resulting in smooth winding of the final product.

PE film is breathable while waterproof.
PE breathable film is primarily used in the hygiene industry for products like baby diapers, female sanitary pads and liners. It is also suitable for applications where both waterproofing and breathability are desired, such as making disposable surgical gowns, breathable clothing, fresh fruit and vegetable packaging, medical packaging, and coverings for construction materials.
Pinholes in the film
Insufficient drying of the raw material
Winding defects
Improper adjustment of film thickness
Tight film
Excessive tension during winding
Varying thickness of the film without changing settings or dies
Poor material dispersion
Low breathability of the film
Insufficient stretching ratio
Poor transverse strength of the film
Excessive stretching ratio
