Problems solved by technology
[0004] Simple non-woven fabrics limit its application fields and need to be used in combination with other materials. The composite of color film and non-woven fabric has been widely used. Non-woven color film needs to be coated with adhesives in the process of casting and compounding. Due to the high price of the adhesive, the cost of the non-woven color film is relatively high

Embodiment 1
[0014] The coating layer is made by mixing 85wt% adhesive and 15wt% low-density polyethylene resin particles. The non-woven fabric and the color film are composited by casting at 240°C, and the thickness of the color film is 8 microns.
Embodiment 2
[0016] 80wt% adhesive and 20wt% low-density polyethylene resin particles are mixed as the coating layer, and the non-woven fabric and the color film are cast and compounded at 260°C, and the thickness of the color film is 15 microns.
Embodiment 3
[0018] The coating layer is made by mixing 70wt% adhesive and 30wt% low-density polyethylene resin particles. The non-woven fabric and the color film are composited by casting at 280°C, and the thickness of the color film is 10 microns.

Abstract
The invention discloses a novel tape-cast composite non-woven fabric colorful membrane which is prepared by compounding a non-woven fabric with a color membrane through tape casting of a coating layer formed by a mixture of an adhesive and a low density polyethylene resin particle, wherein an upper layer is the color membrane, a lower layer is the non-woven fabric, the usage amount of the low density polyethylene resin particle accounts for 15 to 30% of the weight of a coating material, and the thickness of the color membrane is 8 to 15 mu m. Since the low density polyethylene resin particle is cheaper than the adhesive, the non-woven fabric color membrane provided by the invention has reduced production cost while the compounding quality of the non-woven fabric and the color membrane is ensured.
Description
technical field [0001] The invention belongs to the technical field of packaging materials and relates to non-woven fabric composite materials, in particular to a novel flow-cast composite non-woven fabric color film. Background technique [0002] Non-woven fabric (English name: Non Woven), also known as non-woven fabric, is composed of directional or random fibers. Exciting, colorful, cheap, recyclable and so on. For example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. Non-woven products are rich in color, bright and bright, fashionable and environmentally friendly, widely used, beautiful and elegant, with various patterns and styles, and are light in weight, environmentally friendly, and recyclable. They are internationally recognized as environmentally friendly products that protect the earth's ecology. Applicable to agricu...
