Abstract

The utility model relates to a multilayer disposable membrane, in particular to a protection membrane which is adhered to an object to protect the surface of the object or is used for sticking dirt. When the multilayer disposable membrane is used, the protection membrane in the outer layer can be torn off when worn or smeared, and the multilayer disposable membrane left can still be used for sticking dirt or protecting surfaces of objects until the membrane is used up.

Description

The deserted film of multilayer

Technical field

The utility model relates to the deserted film of a kind of multilayer, and its structure is plural pad pasting, and pad pasting is that its upper strata of thin layer is contained release layer (look product demand use) and contained pressure-sensing glue with lower floor and be formed by stacking, and the deserted film bottom of multilayer is mould release membrance or release liners.

The application of the deserted film of multilayer is very extensive, nothing more than directly pasting dirty or the protection surface is avoided dirty and wearing and tearing, also can avoid the surface to contain the object oxidation of metal, slows down oxidation rate or strengthen the rerum natura of specific demand.Can be applicable to directly to paste LCD (LCD), furniture body surface, car object surface, the glass object surface of dirty, electronic goods or the object on surface or the like that needs protection is arranged.

Background technology

Prior art is the simple layer pad pasting, many kinds of pad pastings have been arranged at present, except customized single specification is used mostly in specific LCD panel size, the protection pad pasting of other size all must utilize art designing's skill to handle, as protect the dirty or wearing and tearing of pad pasting, tearing it then, this body surface promptly loses protection; If wishing that body surface is protected again then need paste pad pasting (new product) again and utilize art designing's skill to handle, will waste more manpower and material resources.Fig. 1 is shown as and only pastes simple layer protection pad pasting in the prior art on the LCD panel.

Summary of the invention

The utility model plural number pad pasting is the deserted membrane structure of the superimposed composition multilayer of individual layer pad pasting, and wherein the individual layer pad pasting is that release layer (looking product demand uses) is contained on its upper strata of thin layer, and pressure-sensing glue is contained in lower floor, and its bottom is mould release membrance or release liners.After once sticking in body surface, can repeatedly tear each laminating film off,,, also can reduce the manpower and the material resources of repeated adhering so the deserted membrane structure of multilayer has good convenience and novelty up to using to last laminating film.

In the plural pad pasting of the present utility model; the individual layer pad pasting is that its upper strata of thin layer is contained release layer (looking product demand uses) and lower floor and contained pressure-sensing glue and be formed by stacking and be the deserted membrane structure of multilayer; its thin layer is functional films such as high molecular polymer, has isolation, protects object to avoid directly contacting external environment or having it functional.

Thin layer lower surface edge on one side can be designed to not contain the thin layer of pressure-sensing glue, so that the user tears.

Perhaps, thin layer can be designed to two terminal thin film exterior layer all pressure-sensing glue, in order to the dirty use of cleaning.

The specific embodiment

Below illustrate the deserted film of multilayer of the present utility model, but scope of the present utility model only limits to this embodiment absolutely not.

Show as Fig. 2, the deserted membrane structure of the utility model multilayer is that single pad pasting is repeated to be formed by stacking for several times, layer is not followed successively by release layer (looking product demand uses), thin layer, pressure-sensing glue, release layer (looking product demand uses), thin layer, pressure-sensing glue repetition for several times, and its bottom is mould release membrance or release liners.

Wherein, definition of each layer and function are as follows respectively:

Release layer: the chemical coating that reduces adhesion between pressure-sensing glue and the thin layer;

Thin layer: be functional films such as high molecular polymer, have isolation, protect object to avoid directly contacting external environment or having it functional.For example PET, OPP, PE, PVC or the like. and on single-layer PET, cover the functional film that layer of metal just can become sheathing paper;

Pressure-sensing glue: claiming " pressure sensitive adhesive " (pressure sensitive adhesion) again, is to grant the adhesive agent that strength can produce stickiness with affixed object;

Mould release membrance: the general designation of functional film layer and release layer, its thin layer are macromolecule membrane;

Release liners: for comprising paper and release layer.

Claims

1. the deserted film of multilayer is characterized in that, is repeated to be formed by stacking for several times by single pad pasting, and layer is not followed successively by release layer, thin layer, pressure-sensing glue, release layer, thin layer, pressure-sensing glue repetition for several times, and the bottom is mould release membrance or release liners.

2. the deserted film of multilayer as claimed in claim 1 is characterized in that thin layer is the functional film of high molecular polymer, avoids directly contacting external environment in order to isolate, to protect object.

3. the deserted film of multilayer as claimed in claim 1 is characterized in that, thin layer lower surface edge does not on one side contain pressure-sensing glue, so that the user tears.

4. the deserted film of multilayer as claimed in claim 1 is characterized in that, two terminal thin film exterior layer of thin layer all have pressure-sensing glue, in order to cleaning dirty or pasting use.
