PE Breathable Film Extrusion Machine

PE breathable membrane is a new type of breathable and impermeable material. Its main component is polyethylene. Because of its soft skin affinity, high tensile strength and good moisture permeability, it is widely used in various fields of life, such as women's sanitary napkins, pad bottom film, baby diapers and so on. At the same time, PE breathable film is also the most important material for pharmaceutical packaging. PE breathable membrane is also called breathing membrane. At present, PE breathable membrane is basically used in diapers (including baby and adult diapers) and sanitary napkins. Features of PE breathable membrane: 1. Good air permeability It can pass through gas but not water, so it can not only effectively isolate water, but also discharge heat and moisture. It can be used as waterproof material with moisture resistance. 2. Skin friendly and soft PE breathable film has excellent hand feel, and the product is soft and comfortable. Compared with ordinary non breathable membrane, it is not easy to cause eczema and other problems on baby's delicate skin. 3. Excellent tensile and extensibility It can appropriately improve the air convection in the user's small environment and is conducive to skin breathing. 4. Good chemical resistance, not easy to corrosion Principle of PE breathable membrane: PE breathable film is made of LDPE / LLDPE polyethylene resin, mixed with about 50% special calcium carbonate, extruded and stretched to a certain ratio. As polyethylene resin is a thermoplastic material, it can be stretched and crystallized under certain conditions. During stretching, the interface between polymer and calcium carbonate particles peels, and interconnected winding pores or channels are formed around calcium carbonate particles. It is these pores and channels that give the air permeability (wet) function of the film, so as to communicate the environment on both sides of the film. Application scope of PE breathable membrane: 1. Daily necessities: raincoat, suit coat, eye mask, all kinds of tablecloth, shower cap, shower curtain, water bag, tablecloth, etc. 2. Sanitary products: diapers, sanitary napkins, medical surgical clothes, special packaging for medical treatment. 3. Packaging supplies: computer, electrical dust cover, car cover, cosmetics flexible packaging, shopping bags, gift bags, folders and archives. 4. Packaging bags: fashion packaging, cosmetic bags, high-grade stationery, wardrobe, fishing bags, handbags, bags and other product applications.
