Embodiment 1~4
[0025] according to figure 1 Process flow sheet shown, the corresponding blended thermoplastic resin (LDPE, PP, PA6, PET) in Table 1 and other auxiliary agent antioxidant 1010 are uniformly mixed by 100% and 1% by weight, flow from the die mouth Extruded, cooled by a quenching roll at a temperature of 10-60°C to make a film with a thickness of 10-100 μm, and then according to the heat treatment process conditions of Examples 1-4 corresponding to Table 2, heat treatment with a touch roll to obtain a thickness A film of 10-100 μm is used to obtain the thermoplastic resin film material of the present invention.
Embodiment 5~9
[0027] According to attached figure 2As shown in the process flow diagram, the corresponding blended thermoplastic resins (PS, TPU, TPE, TPEA, TPO) in Table 1 and other additives and antioxidants 1010 are uniformly mixed at a weight percentage of 1%, and blown into a film The film tube is melted and extruded by the extruder, and the film tube is formed through the die; the film tube is blown into the compressed air through the wind ring to inflate the film tube, and then cooled and shaped by the shaping frame, and then the film is flattened with a herringbone plate tube, made into a film, and then according to the heat treatment process conditions of Examples 5 to 9 corresponding to Table 2, heat treatment with a touch roll to prepare a film with a thickness of 10 to 100 μm, that is, the thermoplastic resin film material of the present invention.

Embodiment 10
[0033] Attached figure 1 In the process flow shown, the thermoplastic resin PET, modified resin PA66 and its compatibilizer are uniformly mixed in a weight ratio of 60:34:6, and then cast and extruded from the die head, passing through a temperature of 15-50 ° C. The quenching roll is cooled to form a thin film, and the 2 Under the conveying, enter the heat treatment process stage of the touch roller, the temperature is 240 ~ 190 ℃, after 0.5 ~ 1.5s, natural cooling and winding, the film with a thickness of 10 ~ 100 μm is obtained, that is, the thermoplastic resin film material of the present invention is obtained. .
