Description
Technical field
The utility model relates to a kind of paper envelope bag, particularly relates to a kind of wrapping kraft envelope bag.
Background technology
Paper envelope bag is generally used for dress mail, but along with the quietly rise of the growing of product category and express delivery industry, this Envelope bag can be used for packing some less frangible commodity, paper envelope bag is of a great variety in the market, a kind of Envelope bag adopting craft paper to make wherein is had to have involution limit, left and right, this Envelope bag due to manufacture craft comparatively simple, therefore be widely used in packaging bag field, but this Envelope bag has following weak point: 1, the involution limit of the right and left and bag itself are on same, therefore according to common unfolding mode, namely the right and left pressing sack is difficult to sack to open, want to open sack, at sack hand place, sack can only be drawn open, this mode opening sack is obviously inconvenient, 2, the edge line (i.e. outside) of sack the right and left is straight line, and whole sack, just as a sharp cutter, is easy to draw in one's hands when holding this sack, 3, the involution limit of the right and left adopts common heat-sealing head heat-sealing, and the surface, involution limit sealed out is smooth, and due to the constraint by manufacture craft and mechanical precision, what this involution banding with smooth surface closed is not very solid.
Summary of the invention
In view of the deficiency that prior art exists, the utility model innovation provides one and is easy to open, can not cuts hand, involution firmly paper envelope bag, this Envelope bag includes the involution limit of pros and cons bag and the right and left, it is characterized in that: have angle between the involution limit of described the right and left and front bag or reverse side bag, described angle is greater than 90 °.
The edge line on described involution limit is wave or jaggies.
Described involution limit includes upper and lower two-layer trimming, and described upper and lower two-layer trimming is integrated with pros and cons bag respectively, and the medial surface on described upper and lower two-layer trimming is all compounded with plastic film, the lateral surface on described upper and lower two-layer trimming is pressed with gravure corresponding up and down.
The medial surface of described pros and cons bag is all compounded with plastic film, described plastic film is compounded with bubble chamber film.
The trimming up and down on described pros and cons bag and involution limit is all craft paper.
The Envelope bag provided according to the utility model has and is easy to open, can not cuts hand and involution firmly advantage.

Detailed description of the invention
As shown in Figure 1, this Envelope bag is formed in the right and left heat-sealing by an a kind of folding paper, middle part is bag 1, the place of the right and left heat-sealing is involution limit 2, due to a paper one side being compounded with one deck plastic film 3, therefore when sealing, the plastic film 3 of heat-sealing place melts bonding, upper and lower trimming 21 is also just sticked together, thus forms involution limit 2.The involution on involution limit 2 is completed by the heat sealing mechanism of Bag Making Machine, as shown in Figure 4, on involution limit 2, impression has gravure 5 corresponding up and down, this gravure 5 is impressed out by the projection be evenly distributed on heat-sealing die head, because upper and lower trimming 21 is only subject to the heat-sealing of continuous print local pressure, the power therefore extruded is more concentrated, and the plastic film local 8 at the place of being extruded will bond very firm, relatively whole involution limit 2, upper and lower trimming 21 is not easily torn;
In order to allow, Envelope bag is more convenient to be opened, Envelope bag of the present utility model has angle α between its involution limit, left and right 2 and front bag 1 or reverse side bag, this angle α is greater than 90 °, as shown in Figure 1, because involution limit, left and right two 2 is not be in same plane, but shape in an angle, therefore sack just can be easy to strut when pressing limit, the sack left and right sides; In order to allow the edge of sack not easily cut hand, the edge line on involution limit 2 is made into wave 6(as shown in Figure 2 by the utility model) or jaggies 7(is as shown in Figure 3).
In addition, in order to the effect allowing Envelope bag have shockproof abrasionproof, the utility model is composite bubble chamber film 4 on bag 1 medial surface also, and this bubble chamber film 4 is also be bonded on plastic film 3.In addition, it should be noted that, the Envelope bag that the utility model relates to can adopt craft paper or other cardboards.
