Definitions
- the present invention relates to a method for producing a multilayer, but thin barrier packaging material.
- Barrier packaging materials that have a barrier property against gases such as oxygen and aromas include ethylene-vinyl alcohol copolymer (EV ⁇ H), polyamides such as nylon (PA), and silicon oxide (Sio x). And plastic films, and polyethylene terephthalate (PET).
- EV ⁇ H ethylene-vinyl alcohol copolymer
- PA polyamides
- Sio x silicon oxide
- PET polyethylene terephthalate
- Functional film materials are laminated according to various uses, and various multilayer barrier packaging materials are put on the market and proposed.
- the functional film material is laminated as described above according to the functions required of the film, for example, gas barrier properties, fragrance retention, flexibility, and heat sealing properties.
- steps such as pre-processing, laminating process, and post-processing, so that there are disadvantages that the number of processes is large and the processes are complicated.
- the thickness of the entire multi-layered paria packaging material may increase, which may cause a disadvantage that a thin film cannot be obtained.
- the present invention can reduce the number of steps in the process of manufacturing a multilayer barrier packaging material and simplify the process itself.
- An object of the present invention is to provide a method for producing a barrier packaging material which is advantageous in terms of cost and environment by reducing the number of agent layers.
- the invention of a method for producing a thin-layer and multi-layer barrier packaging material involves direct bonding to both surfaces of an ethylene-vinyl alcohol copolymer layer and the ethylene-vinyl alcohol copolymer layer.
- a 205 m thick biaxially stretched film having a polyamide layer and a heat-adhesive polyethylene layer laminated on each outer surface of the polyamide layer via an adhesive resin layer is prepared,
- the surface to be bonded of the 55 m-thick polyethylene terephthalate film and the surface to be bonded of the biaxially stretched film are treated by corona discharge,
- the method for producing a thin and multilayer barrier packaging material according to claim 1 of the present invention comprises the steps of directly adhering to both surfaces of an ethylene-vinyl alcohol copolymer layer and the ethylene-vinyl alcohol copolymer layer.
- the surface to be bonded of the polyethylene terephthalate film having a thickness of 5 m 15 m and the surface to be bonded of the biaxially stretched film are treated by corona discharge,
- the method for producing a thin and multilayer barrier packaging material according to claim 2 of the present invention is characterized in that the thin film is directly adhered to both sides of the ethylene-vinyl alcohol copolymer layer and the ethylene-vinyl alcohol copolymer layer.
- a biaxially stretched film having a thickness of 20 ⁇ 1-45 xm comprising a polyamide layer and a heat-adhesive polyethylene layer laminated on each outer surface of the polyamide layer via an adhesive resin layer;
- a polyethylene terephthalate film having a thickness of 5 m to 15 m and having a silicon oxide vapor deposited layer (Six) on one side;
- the polyethylene terephthalate film and the biaxially stretched film After the treatment, the polyethylene terephthalate film and the biaxially stretched film The surface to be joined is heated and pressed by a nip roll.
- the method for producing a thin and multilayer barrier packaging material according to claim 3 of the present invention comprises the steps of directly bonding both sides of an ethylene-vinyl alcohol copolymer layer and the ethylene-vinyl alcohol copolymer layer.
- a biaxially stretched film having a thickness of 20 m to 45 m having a polyamide layer and a heat-adhesive polyethylene layer laminated on the outer surface of each of the polyamide layers via an adhesive resin layer is prepared,
- Both surfaces of a polyethylene terephthalate film having a thickness of 5 m—15 rn and a surface to be joined of the biaxially stretched film are subjected to an activation treatment for improving adhesion,
- the surfaces to be joined of the biaxially stretched film are heated and pressed against the both surfaces of the polyethylene terephthalate film by nip rolls.
- the ethylene-bilayer A polyamide layer (PA) directly adhered to both sides of the alcohol copolymer layer (EVOH) and the ethylene-vinyl alcohol copolymer layer (EVOH), and an adhesive resin layer (Adh) on each outer surface of the polyamide layer
- a biaxially stretched film having a thickness of 20 m and 45 im having a heat-adhesive low-density polyethylene layer (LDPE) laminated through the above is prepared.
- the biaxially stretched film has a layer structure of LDPE / Adh / PA / EVOH / PAZAdh / LDPE.
- polyamides such as nylon-MXD6, nylon-16 (PA-6), nylon-66 (PA-66) or a blend of nylon-6 and nylon-66 (PA-6 / 66), etc. is there.
- nylon-MXD 6 nylon-16
- PA-66 nylon-66
- PA-6 / 66 nylon-66
- PA-6 / 66 nylon-66
- PA-6 / 66 nylon-66
- the polyamide is a "nylon clay hybrid" (NCH), which can be homogeneously mixed with a polyamide such as, for example, PA-6, PA-66, PA-6 / 66. It is a molecular composite composed of dispersed fine layered silicate.
- nylon-MXD6 with NCH based on PA_6, not only mechanical properties but also optimal gas barrier properties are obtained.
- the treatment is performed on at least the surface to be joined.
- the adhesive layer to be bonded is produced by using an ethylene-acrylic acid copolymer, an ethylene-methacrylic acid copolymer, an ethylene-methyl methacrylate copolymer, an ionomer, a low-density polyethylene, and a methacrylate catalyst.
- Linear low-density polyethylene can be used.
- the barrier packaging material of the present invention is used for a packaging container for storing liquid foods such as milk and soft drinks.
