Description
Technical field
The present invention relates to a kind of packaging bag and its production technologies, more particularly to a kind of food packaging bag and its production work
Skill.
Background technique
Consumer buys the foods such as water fruits and vegetables, seafood, dried food and nuts in supermarket, requires to put into sack, sack is opened
After mouth packs together, the steam of bag interior can not just be distributed, it is easy to lead to the food moldy metamorphism in sack.In order to mention
The gas permeability of high sack, someone improve, and the sack that production is good and is stacked, then take and are rushed on punching apparatus
Hole, the hole rushed out while the front and back for punching sack.
This sack for having perforation, although gas permeability can be improved to a certain extent, the size in hole is smaller, no
It can do greatly, otherwise cause to leak, air permeability effect is bad, moreover, the front and back of sack is punched in hole simultaneously, this kind of sack is not
It can be used in the food that dixie cup, jelly, sauce, pickled product etc. have water.Certainly, there are also the sacks for being used to fill liquid, but
It is that this kind of sack is often jumped the queue a water nozzle at the position that front and back encapsulates (on the corner location of side), utilization is positive
Film and the film at the back side encase water nozzle, this needs very high seal request, and leak, production difficulty are otherwise easy between sack and water nozzle
Greatly.
Summary of the invention
The present invention provides a kind of packaging bag and its production technologies, and packaging bag is only in one side molding air hole or charging
Hole.The technical solution adopted by the present invention to solve the technical problems is:
Packaging bag production technology, comprising steps of film is pulled out from unwinding device after coming, using cutting device by film
It is cut from centre, film is bisected into front side films and back side film two parts;Front side films are under the guiding conveying of conveying roller by punching
Device, the intermittent punching of perforating device in front side films so that form the hole equidistantly arranged, guiding of the back side film in conveying roller
Convey lower stroke identical with front side films experience, front side films from perforating device export after with back side film consistency from top to bottom;Later, it encapsulates
It is folded to form upper layer and lower layer structure among counterdie and delivers between front side films and back side film, encapsulates counterdie close to front side films
With the lower edge position of back side film, encapsulates counterdie, front side films and back side film three's parallel synchronous and deliver into heat-sealing device;Heat-sealing
Device seals front side films, back side film, encapsulation counterdie, and upper layer and lower layer encapsulate counterdie respectively and under front side films and back side film
The upper edge heat-sealing of edge heat-sealing, front side films and back side film forms lateral edge sealing, and front side films and back side film exist
The left and right sides in hole seals respectively forms vertical edge sealing, and vertical edge sealing, lateral edge sealing, encapsulation counterdie, front side films, back side film are together
Form chamber;After heat-sealing, hole punched device punching on lateral edge sealing and/or vertical edge sealing forms handle hole.
Packaging bag production technology, comprising steps of film is pulled out from unwinding device after coming, using cutting device by film
It is cut from centre, film is bisected into front side films and back side film two parts;Front side films are under the guiding conveying of conveying roller by punching
Device, the intermittent punching of perforating device in front side films so that form the hole equidistantly arranged, guiding of the back side film in conveying roller
Stroke identical as front side films experience after conveying, front side films from perforating device output after with back side film consistency from top to bottom;Later, net
Lattice film delivers between front side films and back side film, the hole consistency from top to bottom of grid film and front side films, grid film, front side films and back
Facial mask three's parallel synchronous delivers into heat-sealing device;Heat-sealing device seals front side films, back side film, grid film, front
The surrounding and grid film heat-sealing in the hole of film, the direct or indirect heat-sealing in the lower edge of front side films and back side film, just
Facial mask and back side film seal respectively in the left and right sides in hole forms vertical edge sealing, vertical edge sealing and front side films at left and right sides of hole,
Back side film, which is matched, is encircled into chamber.
Packaging bag, including front and back, the left and right sides heat-sealing of front and back, under front and back
The direct or indirect heat-sealing in bottom edge, the front are equipped with air hole or charging hole, and the back side is complete surface, when
Grid film and the surrounding heat-sealing with air hole are equipped in bag when the setting air hole of front.
The technical program compared with the background art, it has the following advantages:
1. directly in the charging of the ventilative air hole of front molding either charging in the production process of sack
Hole.Only charging hole is set on one face, allows packaging bag to be used to the dixie cup either food containing moisture content, facilitates reality
With, air hole can with.Only air hole, and interior His-Wife grid film are set on one face, prevent article in bag from dropping out, simultaneously
Air hole can be done greatly, and air permeability effect is good.
2. the present invention sets the shift position of front side films and back side film by adjusting the forming step of packaging bag,
In conjunction with perforating device, so that packaging bag is only in one side providing holes, packaging bag practicability is stronger, and production technology is also simple.
