Abstract
The utility model provides a non-drying adhesive envelope with long effective time. The paper of the sealing mouth of the non-drying adhesive envelope with long effective time is firstly covered with an impervious layer, and then the non-drying adhesive is smeared on the surface of the impervious layer, so that the non-drying adhesive can not lose adhesiveness because of infiltration and aging, and the service life of the non-drying adhesive is prolonged.
Description
The utility model provides a kind of envelope, and a kind of sealing part scribbles the envelope of not doing.Be applicable to and post ordinary mail, various types of envelopes such as registered letter, official letter letter, printed matter.
I am directly to be coated with non-drying glue on the paper at envelope sealing place in the patent " non-drying glue envelope (application number 99234004.7) " of application on September 3rd, 1999, and then attached one deck protection sheet forms.Because non-drying glue is directly to be coated on the paper, and paper has very strong penetrablility, store and just can wear out gradually soon, make non-drying glue lose viscosity, so the effect phase that this envelope is deposited is short.
The purpose of this utility model is that a kind of improved envelope will be provided, and the non-drying glue of its sealing part can not wear out and lose viscosity, and the very long effect phase is arranged.
The purpose of this utility model is achieved in that when producing envelope, is coated with one deck non-drying glue again in cover one deck antiseepage film on the paper at envelope sealing place on the antiseepage film surface earlier, at last attached one deck separate paper on the non-drying glue aspect.During use, take separate paper off, just sealing firmly of envelope can be clung.
The utility model is because of being covered with one deck antiseepage film on the paper at envelope sealing place, non-drying glue layer is the interlayer that is sandwiched between impervious barrier and the separate paper, and separate paper also has the antiseepage function, therefore can guarantee effectively just that non-drying glue layer can not lose viscosity because infiltration occurs aging, the phase is imitated in the use that has prolonged the non-drying glue envelope widely.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
With reference to accompanying drawing, masking paste is coated on the paper of envelope sealing [1] near the inlet one side, promptly form antiseepage film [2] (antiseepage film [2] also can obtain by the method for the multiple film of plastics hot pressing, can also obtain by the method for pasting plastic adhesive tape) after doing.Be coated with one deck non-drying glue solution on impervious barrier [2] surface again, dried slightly, form nondrying layer [3], at last at surperficial attached one deck separate paper [4] of non-drying glue layer [3].
