Abstract
This application involves food package film fields, packaging film and packaging bag are easily torn more particularly to a kind of straight line, the straight line easily tears packaging film and is made of four tunic layers, and the four tunics layer is successively are as follows: pet film layer, aluminum foil film layer, polyamide laminate film and layer of polypropylene foil.Wherein the polyamide laminate film is equipped with the linear type laser rays for tearing the packaging film.When tearing this packaging film, the strength of tearing is concentrated on linear type laser rays user, to tear out linear tearing port, and since laser rays only is arranged in polyamide laminate film, packaging film can be made to have good sealing performance.The utility model also provides a kind of packaging bag using above-mentioned packaging film preparation, is likewise supplied with the above advantage.
Description
Technical field
The utility model relates to packaging bag fields, and in particular to a kind of straight line easily tears packaging film and packaging bag.
Background technique
Packaging film in life is wound packaging to the cargo being deposited on supporting plate, and packing material is more firm clean and tidy, more
Superpower waterproof action, is widely used.And packaging bag is generally referred to as the internal sack that there is certain space to pack various articles,
Article is set to be easy to save, convenient transportation is widely used among all trades and professions, more wide in the application of food pack field
General, wherein bellows pocket refers to that the both sides of the edge of bag body are folded into toward bag body inner face, reduces the sack of space occupied.
For some packaging films being not provided with for guiding the linear type laser rays torn or packaging bag, only relies on and tear
It is relatively difficult.Due to not having the guidance of linear type laser rays, even if packaging film or packaging bag are torn, the track of tearing is not yet
It will form straight line, unsightly, the packaging bag tearing port torn is easy bigger than normal the packaging film torn out, keeps content unrestrained.Have
Partial packaging film or packaging bag is equally provided with linear type laser rays to guide user to tear out linear tearing port, still
This linear type laser rays generally runs through the entire film layer of packaging film and packaging bag, has a certain impact to its airtight performance.
Utility model content
The utility model aim is to provide a kind of straight line and easily tears packaging film and packaging bag, can tear out linear tearing
Mouthful, and there is good airtight performance.
The technical solution adopted in the utility model is that a kind of straight line easily tears packaging film, which is made of four tunic layers,
The four tunics layer is successively are as follows: pet film layer, aluminum foil film layer, polyamide laminate film and polypropylene are thin
Film layer, wherein the polyamide laminate film is equipped with the linear type laser rays for tearing the packaging film.
Preferably, the linear type laser rays is with the discontinuous line segment in interval.Laser rays refers to laser marking machine
The label got, this laser marking machine is adjustable to get linear type laser rays interval, when linear type laser rays be with
When discontinuous line segment, the Integral sealing performance of packaging film is more superior.
Preferably, the linear type laser rays is one section of continuous line segment.When linear type laser rays is the continuous line in one end
Duan Shi, user's required strength in tearing is less, can tear out one section of linear tearing port easily.
The utility model also provides a kind of packaging bag that packaging film production is easily torn using above-mentioned straight line.
Preferably, the positive bag face and anti-bag face of the packaging bag are that the straight line easily tears packaging film.In positive bag face and instead
Bag face is respectively provided with straight line and easily tears packaging film, and packaging bag is easier to be torn.
Preferably, the linear type laser rays in positive bag face and the linear type laser line position in anti-bag face are opposite.Use the straight line
The linear type laser line position in the easy packaging bag for tearing packaging film production, the linear type laser rays in positive bag face and anti-bag face is opposite,
It overlaps, when user firmly tears packaging bag, linear type laser rays plays guiding function, and the strength of tearing collects in packaging bag
Linear type laser rays at, to tear out linear tearing port.Swash simultaneously as being only provided with linear type in polyamide laminate film
Light, trilamellar membrane layer in addition, i.e. pet film layer, aluminum foil film layer and layer of polypropylene foil are not set
The integrality that linear type laser rays is able to maintain structure is set, therefore packaging bag can integrally have good sealing performance.
Compared with prior art, the utility model have it is following the utility model has the advantages that
The straight line of the utility model easily tears and is provided with linear type laser rays on packaging film polyamide laminate film therein, in user
When tearing packaging film, which plays a part of to guide tearing port, and the strength of tearing collects in the linear type of packaging film
At laser rays, to tear out linear tearing port.The packaging film of four tunic layers composition, only polyamide laminate film therein is provided with
Linear type laser rays, other trilamellar membrane layers maintain the integrality of structure, make packaging film that can integrally have good leakproofness
Energy.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the film layer structure figure for the preferred embodiment that the utility model straight line easily tears packaging film；
Fig. 2 is the overall structure figure for the preferred embodiment that the utility model straight line easily tears packaging film；
Fig. 3 is the overall structure figure of the preferred embodiment of the utility model straight line easily-torn packaging bag；
In figure:
1, pet film layer 2, aluminum foil film layer 3, polyamide laminate film 4, layer of polypropylene foil
5, linear type laser rays
Specific embodiment
Embodiment 1
As shown in Figure 1, a kind of straight line of the utility model easily tears packaging film, the packaging film is by polyethylene terephthalate
Film layer 1, aluminum foil film layer 2, polyamide laminate film 3 and layer of polypropylene foil 4 stack gradually, wherein at polyamide laminate film 3
Equipped with linear type laser rays.
As shown in Fig. 2, easily tearing the overall structure figure of packaging film for the straight line of the utility model, the direction of arrow meaning is to tear
Direction is split, which is equipped with the linear type laser rays 5 for guiding tearing port, which is located at packet
The edge for filling film, extends at the other edge of packaging film, to facilitate user to tear out linear tearing port, the present embodiment
Middle linear type laser rays 5 is one section of continuous line segment, but in further embodiments, which, which can be, has
The discontinuous line segment at interval.
It is four tunics since straight line easily tears packaging film, only polyamide laminate film therein is provided with linear type laser rays, remaining
Trilamellar membrane maintain the integrality of structure, therefore, the utility model packaging film integrally can still have good airtight performance.
Embodiment 2
As shown in figure 3, the present embodiment is a kind of packaging bag, the positive bag face and anti-bag face of the packaging bag are by above-mentioned straight line
Packaging film composition is easily torn, and the laser rays 5 in positive bag face is opposite with 5 position of laser rays in anti-bag face, the laser rays 5 of front and back sides exists
It is overlapped on position, user can also tear out linear tearing port along laser rays 5 easily, likewise, packaging bag is compared to existing
Technology is only provided with laser rays at polyamide laminate film, therefore has good sealing performance.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected
Protect range limitation, those skilled in the art should understand that, can modify to technical solution of the present invention or
Equivalent replacement, without departing from the spirit and scope of technical solution of the present invention.
