Description
Technical field
The utility model relates to the technical field of envelope, especially a kind of waterproof type envelope.
Background technology
Envelope is mainly used in postal delivery mail, conservative communications content, and it is a kind of bag-shaped device of intercommunion document information, generally makes rectangular paper bag.But existing most envelope is made up of the wood-free paper of single layer structure or craft paper usually, and tensile strength and the tear strength of these envelopes are lower, easily occur the phenomenon of disconnected paper, cracking, and waterproof effect is poor, finally causes the breakage of mail in envelope.
Summary of the invention
The technical problems to be solved in the utility model is: in order to solve the prior art Problems existing in above-mentioned background technology, provides a kind of tensile strength and the higher waterproof type envelope of tear strength.
The utility model solves the technical scheme that its technical matters adopts: a kind of waterproof type envelope, has rectangular envelope body, and the unsealed position place of described envelope body is provided with sealing band and can covers the self-adhering type edge sealing of sealing band; The front paper of envelope body and back side paper are all formed primarily of the plastic film layers set gradually from inside to outside, golden yellow layers of kraft paper and waterproof film layer.
Further restriction, is provided with location button in the middle part of the back side of the body of envelope described in technique scheme, is connected with and the lines of locating button and being fastened in the middle part of the outward flange of described self-adhering type edge sealing.
Further restriction, the afterbody of lines described in technique scheme is connected with the one-faced tapes scraps of paper of Pasting at the envelope body back side.
Further restriction, sealing band described in technique scheme is formed primarily of being fixed on front edge sealing and the rear edge sealing be fixed on the paper of the envelope body back side on the paper of envelope body front, the cross section of described front edge sealing and rear edge sealing is all in convex shape, the rear surface of front edge sealing offers U-shaped groove along its length direction, and the front surface of rear edge sealing offers the U-shaped raised line with U-shaped groove match along its length direction.
The beneficial effects of the utility model are: a kind of waterproof type envelope of the present utility model, by all adopting the plastic film layers set gradually from inside to outside, golden yellow layers of kraft paper and waterproof film layer to make on the front paper of envelope body and back side paper, make front paper and back side paper not only have enough tensile strength and tear strength, also there is enough water-proofnesss; Meanwhile, by arranging sealing band and the self-adhering type edge sealing that can cover sealing band at the unsealed position place of envelope body, leak tightness and the water-proofness of envelope body is further increased.
