The PE breathable film special material is a high-performance polyolefin modified material specially developed for the base films of disposable hygiene products and medical protective consumables. To meet the strict requirements of products such as diapers, sanitary napkins, and medical protective clothing for "breathability without water permeability", the PE breathable film special material is scientifically compounded with high-quality polyethylene resin and functional inorganic fillers. It is then processed through high-shear mixing and precise granulation techniques. After forming the film, the breathable micropores are uniform and do not clog, while it also possesses excellent toughness and tensile properties. The color is stable, fully meeting the high-speed extrusion (casting/ blow molding) production process requirements for hygiene breathable films.
Core performance and characteristics of PE breathable film special material:
1. Uniform micropores, breathable but impermeable
Mechanism of action: Select functional inorganic fillers with narrow particle size distribution and high dispersion degree. During the film stretching process, they form a stable interface separation with the base resin, creating a large number of interconnected micropores.
Product characteristics: Uniform pore size distribution, effectively preventing liquid water leakage while allowing water vapor to be smoothly discharged; during the processing, no clogging of pores occurs, and the permeability is stable and controllable.
2. Excellent toughness, not prone to cracking during stretching
Mechanism of action: Through optimizing the resin matrix formula and interface compatibility technology, the stress concentration problem in high-filler systems is improved, enhancing the fracture elongation rate and tear resistance of the material.
Product characteristics: Under high-speed longitudinal/vertical stretching processes, the film is less likely to break or crack, significantly reducing the production scrap rate and ensuring the mechanical strength and durability of the base film.
3. Stable coloring, excellent appearance quality
Mechanism of action: The base material of the special material has good compatibility with various color masterbatches, ensuring that the pigments do not migrate or change color during the stretching and pore formation process.
Product characteristics: The base film is uniformly colored, with pure color, meeting the appearance consistency requirements of high-end hygiene products.
4. Compatible with high-speed extrusion process
Mechanism of action: The melt index and rheological properties of the masterbatch have been precisely controlled, possessing good plasticization and extrusion stability.
Product characteristics: Perfectly compatible with various high-speed stretch film or blow molding breathable film production lines. The extrusion process is stable, the film bubble/film surface is stable, helping enterprises achieve efficient and continuous production.
Application fields of PE breathable film special material:
