Abstract
The utility model discloses a composite polymer film capable of being automatically wound up, which comprises multiple layers of combined polymer films with different shrinkage rates, and each layer of film has a different shrinkage rate. The composite polymer film has strong automatic winding capability, and the drawn-out part in use can be automatically wound up after use, so the composite polymer film is convenient and can avoid waste.
Description
Technical field
The utility model relates to a kind of plastic sheeting, particularly a kind of polymer compound film that can auto reeling.
Background technology
Existing plastic sheeting all can not auto reeling, carry for convenience, it is wound on the spool usually, pull out from spool during use, and the length of pulling out is not easy control usually, tends to the length more than required use, after finishing using, the part that has more can be stretched out outside spool, needs by hand it to be rolled, comparatively trouble.And, even after these redundances of pulling out are spooled, still be easier to scatter, to give to carry and deposit and all bring influence, the film after scattering because of the stained or destruction with external world's touching, causes waste easily.If plastic sheeting can auto reeling, the part that pulls when using so can auto reeling after finishing using, and is not only convenient, but also can avoid waste.
The utility model content
The purpose of this utility model is to provide a kind of polymer compound film that can auto reeling.
A kind of polymer compound film that can auto reeling is composited by two-layer or two-layer above macromolecule membrane, and it is characterized in that: each one of the shrinkage factor of each floor height molecular film is identical.
Composite membrane is composited by the macromolecule membrane that the multilayer shrinkage factor has nothing in common with each other, and can reel from the higher side of trend shrinkage factor after film is pulled out.The part that pulls during use can auto reeling after finishing using, and is not only convenient, but also can avoid waste, and for the occasion that needs are reeled, its use is extremely convenient.As the curtain of the pull-down made with it, when unclamping snap close, curtain can scroll up automatically, and is very convenient; And for example be pasted with the wallpaper or the tablecloth paper of described composite membrane, remainder can oneself be wound on together after it was pasted, and needing artificial curling to pack up, and is very convenient.
The shrinkage factor of each floor height molecular film of described composite membrane can increase progressively or successively decrease successively successively, and composite membrane can be surveyed from the bigger film of trend shrinkage factor and curl, and its crimp force that composite membrane is curled automatically is bigger, and it is quicker to curl, the better effects if of curling.
Description of drawings
Fig. 1 is a kind of schematic diagram of polymer compound film that can auto reeling;
Fig. 2 is a kind of schematic diagram of polymer compound film that can auto reeling.
The specific embodiment
Embodiment 1
As Fig. 1, the PET film 1 (thickness 12um, width 900mm) that transparent simple tension is got adopts the method for extruding to make composite membrane at the different BOPP film 2 of the compound one deck shrinkage factor of one side (thickness 30um, width 900mm).Be cut into the film of 880mm * 800mm; Film will be cut and after typing is handled, this patent product can be obtained.
Embodiment 2
As Fig. 2, on the dry method equipment complex, adopt two component polyurethane type adhesive BOPA film 3 (the thickness 50um that each one of shrinkage factor is identical, width 900mm) BOPP film 4 (thickness 10um, width 900mm) and BOPET film 5 (thickness 20um, width 900mm) are made composite membrane.Compound back trimming on cutting machine, obtaining width is the volume film of 880mm; The volume film is cut into certain specification; After handling, typing can obtain the product of this patent.
Embodiment 3
By the mode that hot pressing is compound transparent heat-sealing type PP film (thickness 40um, width 530mm) and BOPP aluminizer (thickness 12um, width 530mm) that shrinkage factor has nothing in common with each other are made composite membrane.Laminated film is cut after can obtain the product of this patent after the processing of finalizing the design.
PVC film (thickness 50um, width 900mm) the PI film (thickness 10um, width 900mm) and the pvdf membrane (thickness 15um, width 900mm) that adopt two component polyurethane type adhesive that shrinkage factor is had nothing in common with each other on the dry method equipment complex are made composite membrane.Compound back trimming on cutting machine, obtaining width is the volume film of 800mm; The volume film is cut into certain specification; After handling, typing can obtain the product of this patent.
TPU film (thickness 40um, width 1000mm) the PDF film (thickness 10um, width 1000mm) and the TPE film (thickness 10um, width 1000mm) that adopt two component polyurethane type adhesive that shrinkage factor is increased successively on the dry method equipment complex are made composite membrane.Compound back trimming on cutting machine, obtaining width is the volume film of 950mm; The volume film is cut into certain specification; After handling, typing can obtain the product of this patent.
Claims (3)
