The degree that easily rises brokenly is 30 ° of angle 45° angles successively, and 60 ° of angles, 90 ° of angles, hexagonal angle, 150 ° of angles are parabola shaped, round.It therefore, can basis
The demand for heat of content is adjusted, to realize that it is controllable with exhaust velocity that the relieving stagnant Qi that rises is pressed.
Preferably, using PET, ONY or BOPP as printing element, printing technology is gravure printing technique, and ink uses nothing
Benzene is printed without ketone ink；The hot sealing layer material uses polyethylene or polypropylene screen.
Preferably, pouch-shaped made in bag making technique has self-standing bag, three edge sealing bags, back of the body envelope, flanging bag or back of the body envelope
Flanging bag.
It is a kind of can microwave heating exhaust packaging bag, successively be equipped with printing layer, ink layer, glue layer, hot sealing layer, ink layer
It is set between glue layer there are one coating mould release region, is coated on mould release region the stress concentration point that easily rises brokenly there are one setting.
Another kind can microwave heating exhaust packaging bag, successively be equipped with printing layer, ink layer, glue layer, hot sealing layer, it is described
Glue layer is equipped with not glued area, does not set that there are one the stress concentration points that easily rises brokenly on glued area.According to product material structure
Needs, a middle layer by glue composite joint is additionally provided between the ink layer and glue layer.
Preferably, the shape of the above-mentioned stress concentration point that easily rises brokenly be chamfering range R1mm~R10mm rounded corner, 30 °
It is~150 ° of wedge angles, parabola shaped or round.
Invention has the advantages that：The present invention is on combination process using the technique of printing layer positioning gluing, positioning gluing
Not glued in the region of rising brokenly being pre-designed, or in printing layer coating mould release is positioned, it is not multiple to create designated position part
The technique that knife is sealed is scalded in the region of easily rising brokenly closed in bag making technique using the bag making of special designing, scalds knife and is set in advance
The region of rising brokenly of meter is there are one design outstanding, stress concentration when reaching microwave heating and the effect that easily rises brokenly；Projecting point
Design can be adjusted according to the demand for heat of content, to realize that it is controllable with exhaust velocity that the relieving stagnant Qi that rises is pressed.
