Abstract
The invention discloses a milk powder packing film and a production process thereof. The milk powder packing film consists of five layers, sequentially a polyethylene glycol terephthalate film layer (1), a first polyethylene film layer (2), an aluminum foil layer (3), an ethyl acetoacetate resin film layer (4) and a second polyethylene film layer (5). The production process comprises the following steps of: unwinding and sizing the polyethylene glycol terephthalate film layer; unwinding the aluminum foil layer; extruding polyethylene between the polyethylene glycol terephthalate film layer and the aluminum foil layer and performing compaction to compound and stick the three, wherein the polyethylene forms the first polyethylene film layer; unwinding the second polyethylene film layer; extruding ethyl acetoacetate resin between the aluminum foil layer and the second polyethylene film layer and performing compaction to compound and stick the three, wherein the ethyl acetoacetate resin forms the ethyl acetoacetate resin film layer; and winding. The packing film has low thickness, the manufacturing process is simplified, the production period of the packing film is short, the cost is reduced by 15 percent, and the production has low pollution to the environment.
Description
Technical field
The present invention relates to the packaging film that a kind of milk powder packing bag is used, the invention still further relates to a kind of production technology of packaging film.
Background technology
At present, being used for the packed packaging film structure of milk powder in the prior art is four layers, is followed successively by from outside to inside: the PET(pet film), the AL(aluminium foil), the NY(nylon film) or the PET(pet film), the PE(polyethylene film).Wherein PET thickness is about 12 μ m, AL thickness is about 7 μ m, NY thickness is about 15 μ m(PET thickness and is about 12 μ m), PE thickness is about 55 μ m, add between PET and the AL, the glue thickness between AL and the NY/PET, between NY/PET and the PE, its gross thickness is about about 93 μ m, and thickness is bigger.Existing packed packaging film in process of production, between its PET and the AL, between AL and the NY/PET, all bonding between NY/PET and the PE by glue, production cycle is as follows: get the raw materials ready 7 days, printing 1 day, compound slaking 4 days, cut, pack 1 day, ordinary production and arranged 2 days, take 15 days altogether.The shortcoming of this production technology is a complex production process, and manufacturing time is long, the production cost height; And, owing to use glue more, produce and can cause certain pollution environment.
For addressing the above problem, needing badly provides milk powder packaging film and the production technology thereof that a kind of thickness is little, production technology is simple, cost is low.
Summary of the invention
The objective of the invention is to avoid deficiency of the prior art and milk powder packaging film and the production technology thereof that a kind of thickness is little, production technology is simple, cost is low is provided.
Purpose of the present invention is achieved through the following technical solutions:
A kind of milk powder packaging film is provided, and packaging film is formed by five layers, is followed successively by pet film layer, first film layer, aluminium foil layer, ethyl acetoacetate resin thin film layer, second film layer.
Wherein, the thickness of described pet film layer is 12 μ m.
Wherein, the thickness of described first film layer is 15 μ m.
Wherein, the thickness of described aluminium foil layer is 7 μ m.
Wherein, the thickness of described ethyl acetoacetate resin thin film layer is 15 μ m.
Wherein, the thickness of described second film layer is 30 μ m.
A kind of production technology of above-mentioned milk powder packaging film is provided, comprises the steps: the pet film layer is unreeled gluing; Aluminium foil layer unreels; Polyethylene extrusion and compress through pressure roller and chill roll and to make three's compound sticking between pet film layer and aluminium foil layer, polyethylene forms first film layer; Second film layer unreels; Extrude the ethyl acetoacetate resin and compress through pressure roller and chill roll between the aluminium foil layer and second film layer and make three's compound sticking, the ethyl acetoacetate resin forms the ethyl acetoacetate resin thin film layer; Rolling is finished.
Wherein, beat corona before the gluing of described pet film layer earlier.
Wherein, dry after the gluing of described pet film layer.
Beneficial effect of the present invention: owing to adopted above-mentioned structure, the gross thickness of packaging film of the present invention to be about 80 μ m, thickness is little; Packaging film manufacturing process of the present invention is than original packaging film simplified manufacturing process, its production cycle: the 7 days+printing 1 day of getting the raw materials ready+extrude compound 1 day+cut, pack 1 day+ordinary production to arrange 2 days=12 days, and with short production cycle, cost reduces 15%; In addition, owing to use glue less, production pollutes also little to environment.
Description of drawings
Utilize accompanying drawing that invention is described further, but the embodiment in the accompanying drawing does not constitute any limitation of the invention,, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to the following drawings for those of ordinary skill in the art.
Fig. 1 is the cross-sectional view of existing milk powder packaging film.
In Fig. 1, include: 1---pet film layer, 2---first film layer, 3---aluminium foil layer, 4---ethyl acetoacetate resin thin film layer, 5---second film layer.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, milk powder packaging film of the present invention, packaging film is formed by five layers, is followed successively by pet film layer 1(PET), the first film layer 2(PE), aluminium foil layer 3(AL), ethyl acetoacetate resin thin film layer 4(EAA), the second film layer 5(PE).Wherein, the thickness of described pet film layer 1 is 12 μ m.Wherein, the thickness of described first film layer 2 is 15 μ m.Wherein, the thickness of described aluminium foil layer 3 is 7 μ m.Wherein, the thickness of described ethyl acetoacetate resin thin film layer 4 is 15 μ m.Wherein, the thickness of described second film layer 5 is 30 μ m.The gross thickness of packaging film of the present invention is about 80 μ m, and thickness is little.
A kind of production technology of above-mentioned milk powder packaging film comprises the steps: pet film layer 1 is unreeled gluing; Aluminium foil layer 3 unreels synchronously; Polyethylene extrusion between pet film layer 1 and aluminium foil layer 3, and compress through pressure roller and chill roll and to make three's compound sticking, polyethylene forms first film layer 2, polyethylene plays the effect of bonding pet film layer and aluminium foil layer simultaneously, need not to use glue bonding; Second film layer 5 unreels synchronously; Between the aluminium foil layer 3 and second film layer 5, extrude the ethyl acetoacetate resin, and compress through pressure roller and chill roll and to make three's compound sticking, the ethyl acetoacetate resin forms ethyl acetoacetate resin thin film layer 4, the ethyl acetoacetate resin plays the effect of the bonding aluminium foil layer 3 and second film layer 5 simultaneously, need not to use glue bonding; Last rolling is finished.
