Described fire retardant uses polyethylene fire-retardant granule, is conducive to improving anti-flaming function, safe and reliable.

Described air-vent uses the through hole of a diameter of 0.3 millimeter to 1 millimeter, is conducive to improving breathability, prevents from going mouldy.

Described composite bed is used in formula PU or PUR, good hand touch, and wearability is preferable, is conducive to increasing the service life.

The rectangular block that described projection uses width to be 1 centimetre to 3 centimetres, is conducive to increasing contact area, strengthens integrated connection intensity,

Described impervious barrier uses AS film or AF film, the most waterproof, moistureproof, and oil-stain-preventing improves serviceability, expands the scope of application.

The wave structure that described extended layer uses height to be 0.1 millimeter to 0.5 millimeter, is conducive to strengthening extensibility, improves serviceability, increase the service life.

Compared with prior art, this utility model has the advantages that owing to a kind of novel TPU film based on Multiple Protective Structure of the present utility model is widely used in decorating film technical field.Meanwhile, the beneficial effects of the utility model are:

1. the setting of this utility model basic unit, is conducive to improving support strength, strengthens overall construction intensity, increases the service life, improve anti-flaming function, safe and reliable.

The setting of composite bed the most of the present utility model, good hand touch, wearability is preferable, is conducive to increasing the service life.

The setting of extended layer the most of the present utility model, is conducive to strengthening extensibility, improves serviceability, extends serviceability.
