Abstract
The utility model provides a kind of rectangular heavy packaging bag, including two sides M and two port sealing portions, the sides M include two V-shape portions, two sides of the V-shape portion on it, at lower both ends respectively connect hook interconnecting piece by two, the interconnecting piece includes with the sides M longitudinally in the long side section of 45 ° of angles and through the short side section of the corresponding port sealing portion transverse direction, and the outer end of the long side section extends to the apex lines of the V-shape portion.The rectangular heavy packaging bag has the advantages that stacking Founder after packing, beauty and is easy to shipment.
Description
Technical field
The utility model belongs to packaging bag field again, more particularly to a kind of rectangular heavy packaging bag.
Background technology
According to the sorting technique of American-European countries, usually the packet that can carry 10 ~ 50kg solid particles or granular material
Packaging bag of attaching most importance to is generally called in pack.Domestic packaging bag packaged form again includes Polywoven Bag, paper and plastics compound bag, paper bag and FFS weights
Packaging bag.Currently, considerable proportion is still occupied in the form of Traditional Packing based on first three in the domestic market, but with
International and domestic to require environmental protection and resource-effective limitation, the application range of Traditional Packing form can be smaller and smaller, this is novel
The fast development of the FFS packaging bags again of environmental protection, provides good opportunity to develop.
Packaging bag uses the primary " molding-filling-sealing of continuity to FFS again（Form-Fill-Seal, abbreviation FFS）" envelope
Blowing-film for bags prepared by dress technology, has the characteristics that fast package, one-pass molding, sealed damp-proof and printing are good.
For convenient transportation, occupied space is reduced, packaging bag usually also wants stacking to FFS after filling again.In actual operating process,
Packaging bag is susceptible to not upright enough the phenomenon of foot envelope, after bag pile is stacked into certain height, the weight of top or centre to FFS again
Easily there is the phenomenon that slipping pallet in packaging bag, causes the at random of bag pile, is not easy to ship.
To solve the above-mentioned problems, we are seeking always a kind of ideal technical solution.
Utility model content
The purpose of this utility model is in view of the deficiencies of the prior art, to provide a kind of rectangular heavy packaging bag.
A kind of rectangular heavy packaging bag, including two sides M and two port sealing portions, the sides M include two V-arrangements
Portion, two sides of the V-shape portion on it, be separately connected at lower both ends and form two to hook interconnecting piece, the connection
It is in the long side section of 45 ° of angles that portion, which includes with V-shape portion longitudinal direction, and the outer end of the long side section extends to the vertex of the V-shape portion
Line.The heavy packaging bag is bonded or is sutured along two port sealing portions at both ends, then packaging bag will be unfolded again, four faces
Under the long side section connection function, respectively in the outer end of the long side section along the laterally inwardly bending of the V-shape portion, because of length
Side section is in longitudinally 45 ° of angles with the V-shape portion, and the bottom surface and top surface formed after packaging bag expansion again is that horizontal plane forms pros
The rectangular heavy packaging bag of body or rectangular shape.
The interconnecting piece further includes the short side section docked with the long side section, and interconnecting piece connects the angle envelope that two faces are formed and is
Bag shaped structure, the short side section is lateral through the corresponding port sealing portion, can prevent that material is poured into this when filling material
In the envelope of angle, angle envelope, which pours into material and crosses, can not at most be bonded the sealing or suture, influence packaging quality and efficiency.It is described
V-shape portion is sutured or is bonded corresponding to two-by-two at the interconnecting piece respectively, so that it may respectively to connect two sides at its both ends.
The rectangular heavy packaging bag is in a port both seals, the shape between four short side sections in another port sealing portion
At filling opening.
Based on above-mentioned, in order to increase filling opening, and the bonding strength of square-foot envelope is kept, is keeping long side section certain
In the case of, short side section being longitudinally extended along the V-shape portion.
Filling for convenience based on above-mentioned, the apex lines of outer end towards the V-shape portion of the short side section tilt, one
Port sealing portion forms the filling opening of V-arrangement between two short side sections.
The utility model has substantive features and progress compared with the prior art, specifically, the utility model to hook
It is rectangular angle envelope after the expansion of shape interconnecting piece, pack stacking is upright, beautiful, is not easy to slip after packaging bag stacking again, is easy to ship.

Fig. 2 is the structural schematic diagram after the bottom surface of the utility model is unfolded and is folded up.
Fig. 3 is the state diagram after the utility model material filling packaging.
Fig. 4 is the structural schematic diagram of embodiment 2.
In figure, 1. port sealing portions, 2.V shapes portion, 3. interconnecting pieces, 4. long side sections, 5. short side sections, 6. apex lines, 7. is bag-shaped
Angle seal structure, the filling opening of 11.V shapes, 51. slant width edge sections.
Specific implementation mode
Below by specific implementation mode, the technical solution of the utility model is described in further detail.
Embodiment 1
As shown in Figure 1, Figure 2 and Figure 3, a kind of rectangular heavy packaging bag, including two sides M and two port sealing portions 1, institute
It includes two V-shape portions 2 to state the sides M, and two sides of the V-shape portion 2 on it, at lower both ends respectively connect hook by two
Portion 3 connects, and two faces that the interconnecting piece 3 connects form bag-shaped foot seal structure 7.The interconnecting piece 3 includes vertical with the sides M
To the long side section 4 for being α in angle and through the correspondence 1 lateral short side section 5 of port sealing portion, wherein α=45 °, the length
The outer end of side section 4 extends to the apex lines 6 of the V-arrangement flap 2.The inner end of the short side section 5 extends to the port sealing
The outside in portion 1 and being longitudinally extended along the V-shape portion 2.
Embodiment 2
As shown in figure 4, the present embodiment difference from example 1 is that, the short side section be slant width edge section 51, it
Outer end towards the V-shape portion apex lines tilt, port sealing portion 1 forms V between two slant width edge sections 51
The filling opening 11 of shape, convenient for the filling of material.
By taking film bag as an example, for the utility model in processing, the packaging film of long tubular first suppresses the sides M, then with pair
Hook abnormity hot knife sealed out in the V-shape portion it is described to hook interconnecting piece, then use strip hot knife in sack one end
The port sealing portion heat-sealing, both processed to form rectangular heavy packaging bag.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model rather than limits it
System.Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
Understand, can still modify to specific embodiment of the present utility model or some technical characteristics are equally replaced
It changes, without departing from the spirit of technical solutions of the utility model, should all cover in the claimed technical solution of the utility model
In range.
