Description
Technical field
The present invention relates to a kind of food pack and its edge sealing process.
Background technology
Compound the used glue of the food packs such as paper product, flexible package is applied at present, mainly there is oiliness Laminating adhesive
And aqueous laminating adhesive, the existing country is based on oiliness Laminating adhesive.Oiliness Laminating adhesive has many drawbacks, such as inflammable, explosive, poisonous, damage
Evil industrial worker health, food security is influenceed, environment is polluted, is had that disaster hidden-trouble, energy consumption are high, efficiency is low, high cost, this
It is a bit well-known.The most oiliness Laminating adhesives particularly seen on the market at present, these organic solvent type glue are all adopted
With " triphen " class high toxicity organic solvent, the health hazards to people is very big, and is difficult to return to one's perfect health.
Since it is so, why organic solvent type oiliness Laminating adhesive still has sizable market, and its reason is mainly：
First, with the oiliness bridge-type coating machine of organic solvent adhesive production and application for many years, coating machine technology maturation, high precision, greatly
Mostly automatic paper feed, costly, these machines are not general perishable for mechanical price, repair also uncomplicated, so most productions
Producer is unwilling to replace aqueous laminating machine；2nd, organic solvent type oiliness Laminating adhesive and compound film technology have been promoted decades, technology
Maturation, product quality is guaranteed, and many enterprises and technical staff are reluctant to change oneself skilled apparatus and process technology into oneself not
Too familiar novel technique；3rd, the enterprise and laminating adhesive enterprise of supply organic solvent adhesive cooperate for many years, have established
The investment relation of good, stabilization；4th, the enterprise of many oiliness coating machines not yet finds the water that can be used on oiliness coating machine
Property adhesive is also inadequate in the product promotion dynamics of some regional aqueous laminating adhesives；5th, organic solvent type Laminating adhesive price compares water
Property Laminating adhesive is cheap, makes some enterprises not consider to use aqueous laminating adhesive based on cost consideration；6th, in the market is a bit aqueous
Laminating adhesive product quality is bad, or the quality of production is unstable, or food pack restriction of production, is not suitable for being applied to paper product, soft
The high-grade paper-plastic lamination product such as composite packaging, the Front cover of book and periodical of food pack such as bag.
Above-mentioned is still using upper technology restriction the reason for be the reason for aqueous laminating adhesive could not be widelyd popularize, its most critical.
As used the compound food pack of aqueous compound adhesive at present, when heat sealing machine carries out heat-sealing flanging into bag, because of aqueous compound adhesive
The edge sealing foaming so that packaging bag is not tolerated to high temperature.On the one hand the outward appearance of packaging is destroyed, on the other hand packaging is then have impact on
The sealing of bag, bag yield rate is low.
The content of the invention
Regarding the issue above, the present invention provides a kind of food-safe, attractive packages, good airproof performance and environmental protection
Food pack and its edge sealing process.
The present invention is achieved in that a kind of food pack, with the bag being made up of the heat-sealing flanging of two panels film paper, bag
The edge sealing edge of body is integrated by the aqueous laminating adhesive heat-sealing flanging between two panels film paper, and the edge sealing edge stylus printer of bag has pin
Hole, the purpose for setting pin hole is to volatilize to discharge pressure in high temperature using aqueous laminating adhesive, makes to avoid foaming during its heat-sealing flanging.
The present invention, the pin hole at the edge sealing edge of bag can be arranged in matrix, of course it is not excluded other be conducive to it is aqueous multiple
Film glue uniformly volatilizees and discharges the alternative arrangement mode of pressure.
The present invention, the edge sealing edge of bag is had an injection pinhole diameter size, the area based food packaging of pin hole matrix in hole
The specification adjustment of bag is set.
A kind of present invention, edge sealing process of food pack, is carried out in following processing steps：Make bag → bag edge sealing
Cover the hole → mistake heat sealing machine heat-sealing flanging → hot pressing of having an injection of aqueous laminating adhesive → bag edge sealing edge and be made food pack in edge.
The present invention, the glue-spread that bag edge sealing edge covers aqueous laminating adhesive is 6~12g/m2, cross heat sealing machine heat-sealing flanging
Temperature is 160~240 DEG C.
The present invention, has the positive effect that：It is food-safe due to being combined using aqueous laminating adhesive；Traditional food bag
The use water-base cement Composite laminated food packaging bag that pack edge sealing does not punch can only tolerate 120 DEG C of high temperature, could not be by heat-sealing standard
Flanging, so finished product edge sealing easily bubbles after heat-sealing, sealing is poor；By the aqueous compound adhesive of this technological improvement of the invention
Compound food pack, is resistant to 180 DEG C of high temperature flanging standard, and edge sealing bubbles this when solving heat-sealing flanging well
Technical barrier, good airproof performance improves bag yield rate.With the excellent of food-safe, attractive packages, good airproof performance and environmental protection
Point.
Example below is described with reference to the drawings that the present invention is further illustrated.
Brief description of the drawings
Fig. 1 is the structural representation of one embodiment of the present of invention；
Fig. 2 is the mplifying structure schematic diagram at the edge sealing edge of the bag of Fig. 1 embodiments.
In figure, 1,2, film paper；3rd, the edge sealing edge of bag；4th, pin hole.
Specific embodiment
Reference picture 1, Fig. 2, the present embodiment is a kind of food pack, with what is be made up of the heat-sealing flanging of two panels film paper 1,2
Bag, the edge sealing edge 3 of bag is integrated by the aqueous laminating adhesive heat-sealing flanging between two panels film paper, the edge sealing edge pin of bag
Pin hole 4 is equipped with, the purpose for setting pin hole is to volatilize to discharge pressure in high temperature using aqueous laminating adhesive, makes to be kept away during its heat-sealing flanging
Exempt from foaming；The pin hole 4 at the edge sealing edge of bag can be arranged in matrix, of course it is not excluded other are conducive to aqueous laminating adhesive equal
The alternative arrangement mode of even volatilization release pressure；The edge sealing edge of bag is had an injection pinhole diameter size, the face of pin hole matrix in hole
The specification adjustment of product based food packaging bag is set.
A kind of present invention, edge sealing process of food pack, is carried out in following processing steps：Make bag → bag edge sealing
Cover the hole → mistake heat sealing machine heat-sealing flanging → hot pressing of having an injection of aqueous laminating adhesive → bag edge sealing edge and be made food pack in edge；Bag
The have an injection pin hole in hole of body edge sealing edge is arranged in matrix, and bag edge sealing edge is had an injection the pinhole diameter size in hole, pin hole matrix
The specification of area based food packaging bag is set；The glue-spread that bag edge sealing edge covers aqueous laminating adhesive is 6~12g/m2,
The temperature for crossing heat sealing machine heat-sealing flanging is 160~240 DEG C.
Food pack such as Pet films present invention is mainly applied to be combined using aqueous compound adhesive are compound with brown paper,
Opp films carry out process modification during heat-sealing flanging with the compound grade brown paper food pack of brown paper, so as to improve packaging bag
Final product quality.
With the progressively enhancing increasingly improved with people's environmental consciousness of national environmental protection regulation, food bag of the invention is used
Pack and its aqueous laminating adhesive edge sealing process, can contribute for food security.
