Description
Technical field
It the utility model is related to flexible packing material technical field, and in particular on a kind of novel high-barrier clear stretch film
Film.
Background technology
Existing stretched film is broadly divided into three kinds, as shown in Figure 1, the structure of the first existing stretched film 7 includes nylon film 1
With polypropylene film 2, the two is combined with each other by adhesive for polyurethane;As shown in Fig. 2, the structure bag of second of stretched film 8
Pet film 3, nylon film 1 and polypropylene film 2 are included, three is compounded in by adhesive for polyurethane
Together.The first existing stretched film 7 and existing second of stretched film 8 are commonly used in packaging dried bean curd class, Beef and egg products.
As shown in figure 3, the outer layer of the third existing stretched film 9 is polyethylene terephthalate thin film 3, intermediate layer is aluminium
Paper tinsel film 4 and nylon film 1, internal layer are polypropylene film 2, and four are combined with each other by adhesive for polyurethane, utilize aluminium foil film 4
Excellent barrier property, improves the blocking water of existing the third stretched film 9, oxygen resistance.The third existing stretched film 9 is usually used in wrapping
Fill the food more demanding to barrier such as sausage.
Film usually band printed patterns in stretched film, the general printing element of Flexible-Packaging Industry is Biaxially oriented polypropylene at present
Film, nylon film and pet film, wherein pet film mechanical strength
Greatly, in rigidity, tensile property is poor, and bidirectional stretching polypropylene film and nylon film tensile property are excellent, and nylon film is easily inhaled
Tide, penetrability are larger, very power is weak, creases easily.
Utility model content
The purpose of this utility model is that being directed to deficiency of the prior art, and provide a kind of novel high-barrier clear stretch
Film on film, has performance printable, that stretch-resistance is good, barrier is excellent concurrently.
To achieve the above object, the technical solution that the utility model is taken is:On a kind of novel high-barrier clear stretch film
Film, ecto-entad include bidirectional stretching polypropylene film, polyvinylidene chloride film and polypropylene film, the two-way drawing successively
Polypropylene stretched film, polyvinylidene chloride film and polypropylene film pass sequentially through adhesive bonding.
Wherein, nylon film is also bonded with by adhesive between the polypropylene film and polyvinylidene chloride film.
Wherein, aluminium foil film is also bonded with by adhesive between the nylon film and polyvinylidene chloride film.
Wherein, poly terephthalic acid second is also bonded with by adhesive between the aluminium foil film and polyvinylidene chloride film
Also it is bonded between terephthalate films, or the polyvinylidene chloride film and bidirectional stretching polypropylene film by adhesive
Pet film.
Wherein, the adhesive is polyurethane.
Wherein, the thickness of the bidirectional stretching polypropylene film is 15-40 μm.
Wherein, the thickness of the polyvinylidene chloride film is 10-25 μm.
Wherein, the thickness of the polypropylene film is 45-55 μm.
Sealed by two layers of upper film and form packaging bag, the heat seal strength of the polypropylene film of film is more than 40 N/ on two layers
15mm。
The beneficial effects of the utility model:
Film on a kind of novel high-barrier clear stretch film of the utility model, compared with prior art, biaxial tension is gathered
Polypropylene film, polyvinylidene chloride film and polypropylene film are combined with each other by adhesive.First, polyvinylidene chloride,
Chemical name PVDC, is a kind of thermoplastic polymer of softness number at 160-200 DEG C, and there is linear polymerization from beginning to end to chain
Structure, molecular structure is symmetrical, and crystallinity is high, and for PVDC, since its intermolecular cohesive force is strong, crystallinity is high, in PVDC molecules
Chlorine atom has hydrophobicity, will not form hydrogen bond, and oxygen molecule and hydrone are difficult to be moved in PVDC molecules, so as to make it have excellent
Good oxygen barrier and resistance is moist, and its oxygen barrier is from the influence of ambient humidity.That is, in any degree or humidity bar
Under part, have the ability for obstructing steam, oxygen, smell and fragrance of brilliance concurrently, the generation of Food Oxidation denaturalization phenomenon can be delayed,
Shelf life is greatly prolonged, while the fragrance of content can be avoided to scatter and disappear and prevent the intrusion of exterior bad smell.Secondly,
The characteristics of bidirectional stretching polypropylene film printability is good, tensile strength, impact strength, excellent deflection.Further more, polypropylene film
Have the characteristics that tensile strength is preferable.The composite membrane being made of above-mentioned three kinds of thin-film materials(On novel high-barrier clear stretch film
Film), have performance printable, that stretch-resistance is good, barrier is excellent concurrently.
Brief description of the drawings
Fig. 1 is the structure diagram of the first existing stretched film.
Fig. 2 is the structure diagram of existing second of stretched film.
Fig. 3 is the structure diagram of the third existing stretched film.
Fig. 4 is the structure diagram of film in the new stretched film of this reality.
Reference numeral:
1- nylon films, 2- polypropylene films, 3- pet films, 4- aluminium foils film, the two-way drawings of 5-
The first existing stretched film of polypropylene stretched film, 6- polyvinylidene chloride films, 7-, existing second of the stretched film of 8-, 9- are existing
