Abstract
Aluminized packaging composite film the utility model discloses a kind of inexpensive pickles, composite membrane is made up of printing layer, barrier layer, hot sealing layer three-decker, printing layer is biaxially oriented polypropylene film, barrier layer is vacuum polyester aluminizer, hot sealing layer is three-layer co-extruded modified polyethylene film, is bonded between each layer by two-component polyacrylate adhesive.The packaging composite film has that cost is low, resists pungent, low-temperature heat-sealing, the features such as being adapted to pasteurize, is widely used in the pungent class pickles class product packaging of high salt succulence.
Description
Technical field
The packaging of the pungent class pickles class product of food packaging field, particularly high salt succulence is the utility model is related to, is had
Body is that a kind of inexpensive pickles are aluminized packaging composite film.
Background technology
Vacuum aluminized film is one kind of vacuum evaporation metallic film, and it is in high vacuum（10 more than mba）Under the conditions of,
Aluminium fusion and gasification is made with the heating of resistance, high frequency or electron beam, laminated film is formed in the surface attachment of film substrate, in plastics
Film or paper surface plate the very thin metallic aluminium of last layer and become metallized film or aluminized paper.At present, make in packaging material
With it is most be that polyethylene terephthalate film vacuum is aluminized（VMPET）, i.e. polyester aluminizer.It is general more as barrier material
Expect to be used for composite package film intermediate layer, for light blocking, heat-insulated, reduction vapor, OTR oxygen transmission rate.Pickles class product for example squeezes
Often there is the condiment such as high salt, succulence, pungent in dish, sauerkraut, preserved vegetable, therefore, product has certain antiseptic power in itself, is wrapping
More focus on pasteurize, the heat seal property problem of packaging material during dress.
However, the polyester aluminizer VMPET of traditional handicraft not water boiling resistances, can not meet food package film pasteurize work
Skill, separation of easily aluminizing, so as to destroy the performance of composite membrane.The aluminizer of water boiling resistance level is plated using chemical application polyester more
Aluminium film, i.e., chemical aluminizer, such as the enhanced aluminizer of Du Pont's foundation for a great undertaking, the performance that can meet boiling water boiling using coating aluminum plating process will
Ask, but price is too high, 3 times of almost common aluminizer.Aluminium foil metalloid material is broken producing rate variance, and fracture, which has occurred, to be caused
Barrier property is lost.
Therefore, packaging film of aluminizing is developed for pickles class product packaging, especially meets 80-100 DEG C of pasteurize temperature
Degree, it is always the important topic in packaging material field.
The content of the invention
A kind of inexpensive pickles provided by the utility model are aluminized packaging composite film, are had cost low, are resisted pungent, Low Temperature Thermal
Envelope, be adapted to pasteurize the features such as.
In order to solve the above technical problems, technical scheme is used by the utility model：A kind of inexpensive pickles are aluminized bag
Composite membrane is filled, the composite membrane is made up of printing layer, barrier layer, hot sealing layer three-decker, and printing layer is biaxially oriented polypropylene film,
Barrier layer is vacuum polyester aluminizer, and adhesive adhesive linkage is provided between the adjacent layer of the composite membrane；The barrier layer thickness exists
12 microns, and the thickness of aluminizing of vacuum polyester aluminizer is in 35-50nm；The coating weight of adhesive adhesive linkage is in 2-3g/m2。
Further, the thickness of the printing layer is 18-28 microns.
Further, the thickness of aluminizing of the vacuum polyester aluminizer is at 40 nanometers.
Further, the thickness of described heat-sealing film is 60 microns.The blending of 10wt%-30wt% metallocenes is added in heat-sealing film
Modified poly ethylene, wherein metallocene PE density≤0.915g/cm3。
Further, institute's adhesive adhesive linkage is two-component polyacrylate adhesive adhesive linkage, and coating weight is in 2g/
m2。
The utility model beneficial effect：
1）The structure of the composite membrane simply understands that preparation technology is simple；
2）Membrane material of aluminizing is used as barrier material, there is good pliability, avoid aluminum foil material breakage problem；
3）Using two-component polyacrylic acid Aqueous Adhesives, compared with traditional solvent-borne adhesive, no solvent residue is secondary
Pollution, and its thickness and spread are strictly controlled, adhesive property is good, safety and environmental protection.
The pickles class packaging composite film that the utility model is produced has the features such as technique is simple, and cost is low.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
1 is printing layer in figure；2 be barrier layer；3 be hot sealing layer；4 be adhesive adhesive linkage.
Embodiment
The utility model, but the scope of the requires of the utility model protection are further illustrated with reference to embodiment and accompanying drawing
It is not limited to the scope of embodiment statement.
The packaging composite film as shown in figure 1, a kind of inexpensive pickles are aluminized, the composite membrane is by printing layer 1, barrier layer 2, heat-sealing
Layer 3 three-deckers composition, printing layer is biaxially oriented polypropylene film, and barrier layer is vacuum polyester aluminizer, the phase of the composite membrane
Adhesive adhesive linkage 4 is provided between adjacent bed；The barrier layer thickness is at 12 microns, and thickness of aluminizing is in 35-50nm；Adhesive glues
The spread of layer is connect in 2-3g/m2。
In preferable scheme, the thickness of the printing layer is 18-28 microns.It is further preferably 18 or 28 microns.
In preferable scheme, the barrier layer is the thickness of aluminizing of polyester aluminizer at 40 nanometers.Obstructed in the size
Performance and flexility reach preferable balance, in particular for packaging pickles when, each side can meet requirement.
In preferable scheme, the thickness that described heat-sealing film is is 60 microns.Heat-sealing film changes for addition 20% metallocene blending
Property polyethylene, wherein metallocene PE density≤0.912g/cm3, strengthen heat-sealing film durability against pollution.
In preferable scheme, institute's adhesive adhesive linkage is two-component polyacrylate adhesive adhesive linkage, and coating weight exists
2g/m2, there is excellent cohesive force with aluminizer, first, can reach boiling pasteurize requirement, will not aluminize transfer,
Second, relative solvent adhesive for polyurethane, cost are relatively low.
The method for preparing the packaging film, comprises the following steps：
Colored printing formation printing layer is completed to BOPP film using technique is printed in intaglio plate, then using two-component polypropylene
Esters of gallic acid adhesive completes the compound of BOPP/VMPET layers and VMPET/PE layers completion barrier layer and hot sealing layer by gravure technique,
Finished product places 45 DEG C of environment curing 24h, and after natural cooling, composite membrane can be used to pickles automatic packaging.
