coated PE film roll materials

PE Casting Film Production Process: Produced through the casting process. The PE casting film raw material is melted at high temperature, then extruded through a T - shaped die head and cast onto a cooling roller for rapid cooling and forming. Performance Characteristics: It features uniform thickness, high transparency, and excellent heat - sealing performance. With a smooth and flat surface, it can provide a good appearance and packaging effect for diapers. Application in Diapers: It is often used as the bottom film of diapers, serving to isolate urine and prevent leakage to the outside. Meanwhile, due to its good heat - sealing property, it is convenient for composite processing with other materials to meet the forming requirements of the overall diaper structure.  Breathable Film Structural Principle: Generally, based on the PE film, it is given a microporous structure through special processes such as biaxial stretching and micropore formation. These micropores allow water vapor to pass through while blocking liquid water. Performance Characteristics: The most prominent advantage of the breathable diaper film material is excellent breathability, which can discharge the moisture inside the diaper, keep the baby's skin dry, and reduce problems like diaper rash caused by moisture. In addition, it also has certain water - resistance and flexibility. Application in Diapers: Mainly used for the outer layer or bottom layer of diapers. While isolating urine, it realizes good breathability and improves the baby's wearing comfort. Lamination Film Lamination Structure: Composed of two or more layers of different materials. Usually, the lamination backsheet film serves as the base layer, which is combined with other functional materials (such as non - woven fabric, breathable film, absorbent material, etc.) through methods like heat pressing and adhesive coating.  Performance Characteristics: It combines the advantages of each component material, having good flexibility, breathability, water - resistance, and mechanical strength. For example, compounding with non - woven fabric can increase softness and tactile comfort; compounding with breathable film can further enhance breathability. Application in Diapers: Can be used in multiple parts of diapers. For example, as the overall outer layer structure, it can ensure leak - proof function while providing a comfortable using experience; it can also be used to wrap the absorbent core to enhance the urine - containing and isolating effect.  Coated Film Processing Method: PE particles are heated and melted by a coating machine, then evenly coated on the surface of other base materials (such as non - woven fabric, paper, etc.), and a PE film layer is formed after cooling and solidification. Performance Characteristics: The coated PE film roll materials can endow the base material with properties such as water - resistance, moisture - resistance, and dirt - resistance, and at the same time enhance the strength and toughness of the base material. The thickness and performance of the coated film can be adjusted according to production requirements.  Application in Diapers: Often applied to the surface layer of diapers or the wrapping layer of the absorbent core. When used as the surface layer, it can make the diaper surface smoother and reduce friction on the baby's skin; when wrapping the absorbent core, it can prevent the leakage of core materials and play a preliminary leak - proof role. If you want to get more information about our products, you can click www.glinknonwoven.com.
