full lamination film back sheet

The non woven full laminated PE film is mainly made of polyethylene (PE) material, which has good water resistance and breathability. It is mainly used to prevent urine leakage and keep the skin dry. Backsheet PE full laminating film is usually laminated of PE film or a lamination of PE film and non-woven fabric. The outermost layer is usually PE film, and the inner layer may contain non-woven fabric to increase comfort. The working principle of full lamination film back sheet is based on its material properties. PE film has good water resistance, which can effectively prevent urine from penetrating into the outside of diapers. At the same time, it has good breathability, which can help dissipate moisture and prevent babies from developing red buttocks. The breathability of PE film is achieved through its microporous structure, which allows water vapor to pass through but prevents liquid from passing through, thus achieving the function of breathability and impermeability.

1. Different sealing performance The coverage area of partial lamination backsheet film is relatively small, usually only coating a part of the non-woven surface, so the sealing performance of the entire product is relatively poor. The full lamination film adopts a more comprehensive covering method, which can cover the entire surface of the non-woven fabric, thereby improving the sealing performance of the product.   2. Different breathability performance Due to the fact that center lamination backsheet film is only partially coated with a thin film on the surface, the overall breathability of the product is good, making it more suitable for producing products that require breathability. However, full lamination film back sheet has relatively poor breathability and is only suitable for producing products that require good sealing performance. 3. Different costs Due to the need to cover the entire surface of non-woven fabric with full film, its production cost is relatively high. However, center lamination backsheet film is relatively cheaper because only a portion of the surface needs to be coated. Therefore, when it is necessary to produce low-cost non-woven fabric products, semi film coating technology is generally used.
