Abstract
The utility model discloses a composite food packaging bag, the film used in the packaging is successively provided with a two-way stretch polyester layer with benzene-free ink printing patterns(1), a nylon layer(22) with polyvinylidene chloride coat(21) and a linear low density polyethylene copolymer layer (3). The utility model has the advantages of good barrier properties and lucifuge performance without benzene, bacterium and poisoning, and is applicable for food packaging.
Description
Technical field
The utility model relates to a kind of packaging bag, especially a kind of food composite package bag.
Background technology
Along with the enhancing of health of people consciousness, people just more and more recognize the meaning of packaging for foodstuff safety, so producing and the various aspects of life emphasize that all packaging for foodstuff do not have the aseptic nothing of benzene and poison this notion.At present, the normal packet pack mostly is individual layer or simple composite bed on the home market, its barrier property, lucifuge poor performance, apt to deteriorate, the taint of odour of the food of packaging, and the printing in the packaging bag is used with the printing ink of benzene class as solvent, people are edible for a long time, contact benzene, can cause very big harm to healthy.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned weak point, and a kind of barrier property is good, the lucifuge performance is good and provide, the aseptic nonhazardous of no benzene, the food composite package bag of suitable used for packing foods.
The utility model is to realize like this, the main body of food composite package bag is a film, and this film bonded assembly successively is the biaxial stretching polyester layer that has no benzene ink printing pattern, the nylon layer that has the polyvinylidene chloride coating, linear low density polyethylene copolymers layer.
As a kind of improvement of the present utility model, described linear low density polyethylene copolymers is five layers of complex film, and bonded assembly is linear low density polyethylene, low density polyethylene (LDPE), ethene successively--ethenol copolymer, low density polyethylene (LDPE), linear low density polyethylene.
As another kind of improvement the of the present utility model, connect with adhesive agent respectively between described biaxial stretching polyester layer, nylon layer, the linear low density polyethylene copolymers layer.
The utility model food composite package bag material of main part film, bonded assembly is the biaxial stretching polyester layer that has no benzene ink printing pattern, the nylon layer that has the polyvinylidene chloride coating, linear low density polyethylene copolymers layer successively.Wherein biaxial stretching polyester (PET) molecule is through directional process, and its excellent performance has special performances in general plastic package material: (1) mechanical strength height, and it is moist, transparent to have a best obdurability, rigidity, resistance to abrasion, resistance; (2) temperature tolerance is good, and the Applicable temperature scope is wide, can reach-70～150 degree; (3) high barrier, the chemical resistance excellence, good integrated water stop, gas barrier properties, to air, the barrier of smell is higher;
No benzene ink printing does not have the aseptic high-barrier food product packing film of benzene material, at first requires can not contain toluene and aromatic hydrocarbon solvent in the printing-ink, and the solvent residual amount of printing back printing ink must be very low (≤2mg/m2).Content of beary metal above the CONEG standard can not be arranged in the pigment in the printing ink and other cosolvent, and its wholesomeness requires to meet the relevant regulations of U.S. FDA and German ink manufacturer association; Secondly, require the good leveling property of printing ink, strong adhesion, lovely luster, with other base material compound tense, compound fastness is good;
The nylon layer of band coating, the advantage of two kinds of high barrier material of this material collection, at first it plays main iris action in this product: (1) nylon has fabulous mechanicalness, very high tensile strength and shock strength, good dimensional stability; (2) chemical resistance, resistance to alkalis and fuel resistance are splendid, and be optical good, and the transparency is high; (3) high barrier, fragrance protectiveness is good, good elasticity, anti-pin hole is difficult for being pierced through by content; (4) sanitation performance is good, and is nontoxic, and nothing is smelt, tasteless. be particularly suitable for the high packing of food hygiene performance requriements; (5) coating promptly is coated with polyvinylidene chloride (PVDC), has high barrier, and good resistance is wet, choke and fragrance protectiveness, and also this good barrier does not change with humidity, and very favourable to the moisture seal packing; (6) stable chemical performance, acid and alkali, alkali, the corrosion of oily and most of organic solvents; (7) resistance to heat is good, and the ability high-temperature sterilization treatment can be used for the cooking food packing;
Linear low density polyethylene copolymers (LLDPE-EVOH), (1) linear low density polyethylene has nontoxic, and nothing is smelt, and is tasteless. have good elasticity, resistance to cold, anti-pin hole; (2) have good low-temperature heat-sealing, the anti-contaminative of sealing is extremely strong; (3) EVOH has high permeation-proof oxygen, and to carbon dioxide, nitrogen, helium all have excellent barrier; (4) high gas barrier property, fragrance protectiveness. but EVOH possess hydrophilic property and hygroscopic property are generally co-extrusion thing interlayer; (5) fuel resistance, chemical resistance is splendid, and ultraviolet resistance has excellent weather resistance; (6) EVOH has very high mechanical strength, elasticity, superficial hardness, resistance to abrasion. high glaze, and low haze, the transparency is high;
Bonded assembly adhesives between biaxial stretching polyester layer, nylon layer, the linear low density polyethylene copolymers layer, require final solvent residual amount low, initial bonding strength is good, the final strength height, and can not destroy internal layer when solidifying, water resistance is good, be fit to boil sterilization or thermophilic digestion sterilization, with coating good adhesive ability being arranged. chemical-resistant and heat sealability are good, have good wettability with film, and the coating processability is splendid.
The utility model adopts the printing ink of these advanced persons' not containing benezene solvent, and through being composited behind the seal in the intaglio plate, it bright in luster has the characteristics of low solvent residue simultaneously.Be best suited for the aseptic high-barrier packaging material of no benzene of used for packing foods.
Description of drawings
Fig. 1 is the structural representation of the utility model food composite package bag film.
The specific embodiment
As shown in Figure 1, the utility model food composite package bag, having successively in the used film of this packaging bag, bonded assembly is biaxial stretching polyester layer 1 (PET), the nylon layer 22 (KPA) that has polyvinylidene chloride coating 21, linear low density polyethylene copolymers layer 3 (LLDPE-EVOH), pattern according to package design uses no benzene ink printing on biaxial stretching polyester layer 1, and employing polyvinylidene chloride coating 21 on the nylon layer 22, the linear low density polyethylene copolymers aspect is five layers of complex film, and bonded assembly is linear low density polyethylene 31 (LLDPE) successively, low density polyethylene (LDPE) 32 (LDPE), ethene--ethenol copolymer 33 (EVOH), low density polyethylene (LDPE) 34 (LDPE), linear low density polyethylene 35 (LLDPE).3 layers on biaxial stretching polyester layer 1, coating nylon layer 2, linear low density polyethylene copolymers use adhesive agent to connect between each layer.
The utility model processing technology: at first do not have the benzene printing ink intaglio printing with biaxial stretching polyester layer 1 film on printer, and then carry out compoundly on dried answering a pager's call, after slaking, cutting becomes finished product again.
The printing technology of 1 no benzene printing ink
No benzene printing ink is different from and contains benzene printing ink, and is many to its every requirement, so the technological parameter of printing is also different, and print out rate particularly, parameters such as oven temperature, rolling tension force, ink viscosity directly influence printing effect and solvent residual amount.
