A kind of plastic-aluminum combined middle envelope insert edge bag
Technical field
The utility model relates to a kind of plastic-aluminum combined middle envelope insert edge bag, belongs to field of packaging material.
Background technology
At present, a lot of employed Aluminum-plastic composite bags of chemical company, wherein envelope and all not plastic squeezes of position, oblique angle behind the sack charged, fall the Bao Shizhong envelope and seal the position with the oblique angle and very easily break, and bag shape are attractive in appearance inadequately.Simultaneously can not go up automatic packaging line.In order to satisfy client's demand, improve so be necessary centering envelope insert edge bag.
Summary of the invention
The utility model is for solving the deficiency that prior art exists; A kind of improved plastic-aluminum combined middle envelope insert edge bag is provided, and envelope insert edge bag is strengthened the weak part of sack in this, thereby has improved the anti-ability of falling bag of sack; And behind the can material, bag shape is smooth, well-pressed, attractive in appearance.
The purpose of the utility model realizes through following measure:
A kind of plastic-aluminum combined middle envelope insert edge bag, envelope and underseal during this insert edge bag is provided with is characterized in that: four edge hot pressing of insert edge bag have top rade and following oblique angle.
The bag limit at the middle envelope position of insert edge bag and bag gummed are one.
Gummed is one through the prong place in two top rade positions of insert edge bag.
The position, twice oblique angles of insert edge bag is also glued together through the prong place and is one.
Envelope insert edge bag is three layers of PET/AL/PE, four layers of PET/AL/PA/PE or multilayer Aluminum-plastic composite bag in plastic-aluminum combined.
Envelope insert edge bag is the 25Kg--50Kg heavy-duty packages in plastic-aluminum combined.
The utility model is compared prior art and is had following advantage:
Envelope insert edge bag in middle envelope that the utility model provides and the envelope plastic squeeze of upper and lower oblique angle; Should in the sack back, seal and envelope position, upper and lower oblique angle by middle envelope insert edge bag; Clamp-on the elevated temperature heat melten gel, reinforce the weak part of sack, thereby improved the anti-bag ability of falling of sack; And behind the can material, bag shape is smooth, well-pressed, attractive in appearance.
1, the middle envelope insert edge bag of middle envelope and the plastic squeeze of position, oblique angle, its anti-bag ability of falling is higher than common middle envelope insert edge bag far away.
2, the glue that is used for plastic squeeze is the elevated temperature heat melten gel, and intensity and effect are far above general glue.
3, behind this plastic-aluminum pocket pile, because middle envelope and position, oblique angle are fixed by glue, bag shape is well-pressed, attractive in appearance, the pile height increases.
4, this bag helps material filling, helps automatic sealing.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
The utility model mainly applies on the 25Kg--50Kg heavy duty packing, and its base material adopts MULTILAYER COMPOSITE aluminium plastic bags such as PET/AL/PE and PET/AL/PA/PE.This packaging bag is provided with the middle envelope 3 at underseal 4 and back, and this packaging bag hot pressing has top rade 1, following oblique angle 2, and the hot pressing limit shape of top rade 1 is broken line shape, and the hot pressing limit at following oblique angle 2 is oblique line shape.
Like Fig. 2, the elevated temperature heat melten gel is clamp-oned by prong 5 positions in the upper and lower oblique angle of packaging bag, makes its insert edge place gummed be one.Reinforced the weak location of sack, improved the anti-bag ability of falling of sack, also made the bag shape of sack more attractive in appearance simultaneously, satisfied client's corresponding demand, reduced sack and in the production and transport process, fallen the packaging bag breakage that bag causes.Be beneficial to automatic packaging line simultaneously and seal, be full of four jiaos of bag when also being beneficial to material filling.
As shown in Figure 1, the plastic-aluminum combined middle envelope insert edge bag of the utility model, envelope 3, underseal 4, top rade 1, following oblique angle 2 during its bag is provided with, the edge sealing 6 at the middle envelope position of bag and bag gummed are one.The limit portion at the upper and lower oblique angle of the front and back sheet of bag glues together respectively and is one.The edge sealing 6 of the middle envelope of soon being scattered originally is glued at it on bag through applying glue, thereby strengthens its intensity.Top rade 1 gummed that is positioned at the sack side is one, and following oblique angle 2 gummeds that are positioned at bag bottom side are one.And accomplish through applying glue in its seam respectively, through middle envelope position and position, upper and lower oblique angle applying glue gummed, make bag shape smooth.
As shown in Figure 2, top rade 1 inside and outside layer gummed scheme drawing, prong 5 is the signal of applying glue position among the figure.Behind top rade 1 gummed, be convenient to heat seal through automatic packaging line.
Fig. 3 is the limit portion applying glue position view at top rade 1, following oblique angle 2, and A, B are the applying glue position among the figure.
Fig. 4 is the edge sealing 6 of middle envelope position, through applying glue, edge sealing 6 and bag gummed is one.
