Abstract
The utility model relates to a double-surface matted biaxially-stretched polypropylene film, which belongs to the technical field of the processing of biaxially stretching polypropylene films; the double-surface matted biaxially-stretched polypropylene film comprises an upper surface matted layer, a middle transparent core layer and a lower surface matted layer which are sequentially composited from top to bottom. Compared with an ordinary single-surface matted film, the double-surface matted biaxially-stretched polypropylene film has a better matted effect, higher haze, lower gloss and milder visual feel; and more importantly, both surfaces are matted, so that the application area of packaging by users are expanded.
Description
Technical field
The utility model relates to a kind of bidirectional stretching polypropylene film of two-sided delustring, belongs to the bidirectional stretching polypropylene film processing technique field.
Background technology
The BOPP matt film is the compound and packaging material of a kind of fashion, top grade.The vision that it can give the people after receiving the stimulation of sunlight and screen for a long time, is had a look the picture and the packing material of the compound book of matt film, figure, color printing with soft, comfortable, dim effect, can anti-eye strain.The principle that matt film produces delustring is the top layer that the delustring material joins film, and drawn makes the film surface alligatoring, thereby light is produced scattering process, plays delustring (mute light) effect.The corona matt film be applicable to printing, compound, low temperature is gold stamping etc.Compound with paper or other base materials after the gluing of light face, be usually used in the surface recombination of books, advertisement booklet, gift bag, make outward appearance that third dimension and excellent handle are arranged.
Common BOPP matt film is formed by three layers: top layer hyaline layer, sandwich layer hyaline layer and delustring layer; Owing to have only a delustring layer; General mist degree can only reach about 75%, wants to reach bigger mist degree through improvement delustring material, and is quite difficult with regard to present technical merit.On the other hand, because of one side is the light face for delustring face another side, the user has certain limitation at packaging process.Therefore need a kind of more high-grade two-sided matt film.
Summary of the invention
For addressing the above problem, the utility model provides a kind of mist degree bigger, and the two sides all has the bidirectional stretching polypropylene film of the two-sided delustring of extinction effect.
For realizing above-mentioned purpose, the technical scheme that the utility model adopted is:
A kind of bidirectional stretching polypropylene film of two-sided delustring comprises from top to bottom compound successively upper surface delustring layer, central, clear sandwich layer, lower surface delustring layer.Upper surface delustring layer, lower surface delustring layer, the material of selecting for use is the delustring material, the delustring material mixes by a certain percentage to extrude with high density polyethylene (HDPE) with random polypropylene and forms.
As the further setting of such scheme, the thickness of said upper surface delustring layer is 2.0-2.5 μ m.
The thickness of said central, clear sandwich layer is 11-25 μ m.
The thickness of said lower surface delustring layer is 2.0-2.5 μ m.
Said central, clear sandwich layer is the HOPP layer, adopts the film-grade HOPP to process, and contains antistatic additive and slipping agent.
Said upper surface delustring layer is a corona treatment delustring layer.
Said lower surface delustring layer is corona treatment delustring layer or non-corona treatment delustring layer.
The bidirectional stretching polypropylene film of the two-sided delustring of the utility model forms three layers of compound structure through co-extrusion.The utility model is compared common single face matt film, and extinction effect is better, and mist degree is bigger, and glossiness is littler, and is visually softer, and main is that the two sides all has extinction effect, can improve the application of consumer packaging.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, the bidirectional stretching polypropylene film of the two-sided delustring of the utility model comprises from top to bottom compound successively upper surface delustring layer 1, central, clear sandwich layer 2, lower surface delustring layer 3.Central, clear sandwich layer 2 is the HOPP layer.
The thickness of upper surface delustring layer 1 is 2.0-2.5 μ m, and the thickness of central, clear sandwich layer 2 is 11-25 μ m, and the thickness of lower surface delustring layer 3 is 2.0-2.5 μ m.
Upper surface delustring layer 1 is a corona treatment delustring layer, and perhaps lower surface delustring layer 3 is a corona treatment delustring layer, and perhaps upper surface delustring layer 1, lower surface delustring layer 3 are corona treatment delustring layer.
The foregoing description only be used to explain inventive concept of the utility model, but not to the qualification of the utility model rights protection allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into the protection domain of the utility model.
Claims (7)
