Abstract
The invention discloses a novel packing bag, which carves open part on the at least one face of packing bag through laser beam to open package easily.
Description
Technical field
The present invention relates to a kind of packaging bag, particularly relate to a kind of later-model, packaging bag of being easy to open.
Background technology
Common packaging bag also will be considered the taking-up mode of packed article except the particular case decision basic configuration according to packed article.Some packaging bag considers that the intensity of packaging bag is important, the setting that does not have special consideration to be easy to open the package in packaging bag.Like this, the customer must oneself manage to open the package.Some packaging bag is adopted to be provided with on side and is easy to tear the vee of packaging bag, perhaps makes impression at the position that will open, such as shapes such as serration, dotted line shapes.Some packaging bag can require lower because of the intensity to packaging bag, open the package for convenience, even do the opening form that the forming V-shape engagement is sealed.These opening forms have solved the needs that take out packed article effectively, have been fit to the requirement of different packed articles.
But also there are some shortcomings inevitably in these opening modes, move towards uncontrollable such as what vee can cause opening when tearing packaging bag, the too small openings of tearing sometimes, and opening is excessive sometimes, even causes scattering of packed article.If serration and dotted line shape impression are too shallow, because the intensity of the material of packaging bag is not easy to open all than higher; And if impression is too dark, can influence the intensity of packaging bag opening part again.And V-arrangement engagement to seal the shortcoming of form be that the packaging bag opening very easily just may be by opening when not wishing to be opened, cause packed article scatter or contaminated.
Summary of the invention
The objective of the invention is to provide a kind of be easy to open the package opening and reliable sealing packaging bag.This packaging bag can be applied widely, and health, safety, reliable are produced and use cost reduces.
Packaging bag of the present invention, it comprises the bag material that constitutes packaging bag, it also is included on the one side at least of above-mentioned bag material and has the opening portion of indentation.
Above-mentioned indentation is the indentation that is carved into by laser beam.
The opening portion of packaging bag of the present invention can be triangle, square, or any shape that other needs.
The bag material of formation packaging bag of the present invention can be a multilayer materials.
Novel package bag of the present invention has following advantage.
1, the customer is very easy to use, reliable---owing to carved indentation with laser beam in advance according to opening shape in packaging bag, the customer very easily opens in use and seals, and scattering of packed article can only can not caused along indentation in the path of opening.And the laser scored degree of depth is suitable, does not influence the intensity of packaging bag.
2, the customer can be at an easy rate laser scored according in the packaging bag, pick out the opening of packaging bag, thereby open the package soon.
3, safe and sanitary is reliable---owing in packaging bag, carve indentation in advance according to opening shape with laser beam, do not destroy or penetrate bag material, this processing is a kind of mechanical treatment of physical property, does not add any objectionable impurities, so health, safety, reliable.
4, range of use is extensive---and packaged beverage can be used for, also other article can be packed.
5, cost is low---owing in packaging bag, made the opening indentation, do not need to add again in addition the outlet device of special packed article,, the productive costs of packaging bag is reduced greatly such as the suction hole of beverage.In addition, manufacturer adds the indentation of having finished opening part man-hour and handles, and therefore uses the producer of this packaging bag not need to increase auxiliary material and the equipment that other considers opening, uses the productive costs of the producer of this packaging bag also to be reduced.
Description of drawings
Fig. 1 represents one embodiment of the invention.
Fig. 2 represents another embodiment of the invention.
Fig. 3 represents the 3rd embodiment of the present invention.
Fig. 4 represents the 4th embodiment of the present invention.
The specific embodiment
Fig. 1 has shown the packaging bag of first embodiment of the present invention.Packaging bag 11 is made up of bag material 12, and the opening portion 13 that forms in packaging bag 11 is triangular in shape, and is positioned at a side of packaging bag one end, and the gable top of opening portion 13 is osed tops.At least one outside face at opening portion 13 forms laser scored 14.Indentation 14 traverses the triangle open mouth part.
Indentation 14 is in the middle of packaging bag manufacturing process, is carved into by laser beam shape as required.Intensity of laser beam can be determined at an easy rate according to the depth and the bag material of indentation.When the definite indentation depth, to consider to be easy to make the customer to open opening, and guarantee the intensity of packaging bag again.
Can behind the packed article of packing into, be sealed according to the difference of packed article, according to the loading port position that packed article in the packaging bag is determined in the shape and the position of packaging bag shape and opening.
As second embodiment of the present invention, packaging bag 21 is made up of bag material 22 among Fig. 2, and the opening portion 23 that forms in packaging bag 21 is triangular in shape, and is positioned at the centre portion at an end top of packaging bag, and the gable top of opening portion 23 is osed tops.At least one outside face at opening portion 23 forms laser scored 24.Indentation 24 traverses the triangle open mouth part.
As the 3rd embodiment of the present invention, the packaging bag 31 among Fig. 3 is made up of bag material 32, and the opening portion 33 that forms in packaging bag is rectangular in shape, and is positioned at a side of an end of packaging bag, and the square top of opening portion 33 is osed tops.At least one outside face at opening portion 33 forms laser scored 34.Indentation 34 traverses the square opening portion.
As the 4th embodiment of the present invention, the packaging bag 41 among Fig. 4 is made up of bag material 42, and the opening portion that forms in packaging bag traverses an end of packaging bag, and the end of opening portion 43 is osed tops.At least one outside face at opening portion 43 forms laser scored 44.Indentation 44 traverses the opening portion of end.
Owing to formed laser scoredly at the outside face of the material of packaging bag, the customer is very easy to find this opening, when the customer wishes to open the package, as long as it is just passable to tear packaging bag from indentation simply.Because indentation has been arranged, opening only can follow the path of indentation, can too small openings, and the uncontrollable situation of opening can not appear yet.Opening shape is fairly regular, can not cause scattering of packed article.
Because being the outside face in bag material, the opening indentation of packaging bag of the present invention forms, operation is very easy to scribe the laser beam of indentation, use packaging bag of the present invention just different shape can be arranged, can decide according to the requirement of the use producer of packaging bag.Packaging bag also can be used different opening shapes, and opening can be leg-of-mutton, ligulate, square, traverse shapes such as packaging bag one end.Material to packaging bag does not have special requirement yet, as long as it is just passable to scribe indentation with laser beam.Usually use bag material multilayer materials commonly used, a kind of such as in the middle of nylon/polyethylene, polyester/nylon/polyethylene, polyester/polyethylene, the polypropylene, polyethylene etc.
Be used for packaging bag of the present invention and can be used to pack different packed articles, the above-mentioned description about packaging bag opening indentation does not constitute limiting the scope of the invention.Any any modification of making according to the above-mentioned basic design of the present invention or change all within protection domain of the present invention.
