Abstract
The utility model provides a multi-layer heat-shrinkable film which comprises a wear layer, flame-retardant layers, a reinforced layer and a base layer. The multi-layer heat-shrinkable film is characterized in that the wear layer is arranged on the outermost layers and comprises an upper layer and a lower layer; the reinforced layer and the base layer are arranged on the inner side of the wear layer; the flame-retardant layer is arranged between the wear layer and the reinforced layer; the flame-retardant layer is arranged between the reinforced layer and the base layer; the flame-retardant layer is arranged between the base layer and the wear layer. The multi-layer heat-shrinkable film has the benefits that the flame-retardant layers made of three-layer polycarbonate material are adopted; the multi-layer heat-shrinkable film has flame-retardant and self-extinguishing functions, higher flexibility and higher tensile resistant performance and the possibility of breakage is low.
Description
Technical field
The utility model relates to heat-shrinkable film technology field, more specifically says a kind of multilayer heat shrinkable film.
Background technology
Heat shrink films has that pliability is good, impact resistance, tear resistance are strong, not cracky, be not afraid of tide, shrinkage factor is large, be widely used in whole assembly package of the products such as drinks, pop can class, mineral water class, various beverage class, cloth, but the heat shrink films combustibility of prior art is strong, in use procedure, very easily burning, not only dangerous, once and burn, just pollute the environment, cause larger economic loss.
Summary of the invention
For addressing the above problem, the utility model has designed a kind of multilayer heat shrinkable film that can fire-retardant, certainly put out, its technical scheme is: described multilayer heat shrinkable film is made up of wearing layer, flame-retardant layer, enhancement Layer, basic unit, it is characterized in that wearing layer is arranged on outermost layer, be set to two-layer up and down, the inner side of wearing layer arranges enhancement Layer and basic unit, between wearing layer and enhancement Layer, enhancement Layer and basic unit, basic unit and wearing layer, flame-retardant layer is set.
Wearing layer described in the utility model, is characterized in that the material of wearing layer adopts oriented polystyrene, and the thickness of wearing layer adopts 0.1～0.5mm.
Flame-retardant layer described in the utility model, is characterized in that the material of flame-retardant layer adopts Merlon, and the thickness of flame-retardant layer adopts 0.05～0.1mm, has stronger anti-flammability and wearability.
Enhancement Layer described in the utility model, is characterized in that the material of enhancement Layer adopts pet resin, and the thickness of enhancement Layer adopts 0.01～0.05mm.
Basic unit described in the utility model, is characterized in that the material of basic unit adopts polypropylene, and the thickness of basic unit adopts 0.01～0.05mm.
The beneficial effects of the utility model are flame-retardant layers that multilayer heat shrinkable film is provided with three strata carbonic ester materials, have fire-retardant, certainly put out function, there is higher pliability, not cracky, stronger stretching resistance performance.
