Description

201247485 VI. [Technical Field] The present invention relates to a resin-made layer container, and more particularly to a resin-made multilayer container in which surface slidability and surface gloss are improved. More specifically, the optimum slidability is exhibited in each of the steps of the manufacturing step, the filling step, and the packaging step of the resin multilayer container, and the liquid repellency is excellent with the contents of the filled contents, and the contents are identified. Improvement of resin-made multilayer containers with excellent properties. [Prior Art] Resin-made multi-layer containers (hereinafter sometimes referred to as "multi-layer containers" or "containers") filled with sticky contents such as sauces or ketchup are mainly extruded by direct blow molding. The billet is then produced by blow molding into a container shape in a cooling mold. The resin material is generally composed of a polyolefin resin such as a polypropylene resin as a surface layer (outer layer and/or inner layer), and a multilayer structure having a barrier layer such as an ethylene/vinyl alcohol copolymer (EVOH) in the intermediate layer. For example, Japanese Laid-Open Patent Publication No. Hei 6-72424 (Patent Document 1) discloses a gas barrier resin layer such as an ethylene/vinyl alcohol copolymer, an outermost layer of a polyolefin resin such as polypropylene, and a multilayer material containing an adhesive resin layer or the like. Further, it is a multilayer bottle body which is produced by direct blow molding or the like. The resin multilayer container requires transparency, gloss, impact resistance, slidability of the surface of the container, and the like. For example, JP-A-2009-248996 (Patent Document 2) discloses an inner layer and an outer layer composed of an ethylene/α-olefin copolymer polymerized using a metallocene catalyst, and a gas barrier resin layer. 201247485 The multi-layer plastic container of the agent layer and the recovery layer is used as a soft container that achieves a balance of transparency, flexibility, rigidity, and drop strength. On the other hand, the impact resistance of a block having a polypropylene obtained by using a specific metallocene catalyst and a block of an ethylene/propylene copolymer is disclosed in Japanese Laid-Open Patent Publication No. Hei No. Hei. No. Hei. Excellent block copolymer. Resin multilayer containers require the surface of the container, specifically the outermost and/or innermost slidability. That is, in the resin multilayer container, the product forming step, the container transporting step, the content determining step of the food determined by the user, the carrying step after the content filling, and the production line or temperature of the container packaging step, etc. In each step in which environmental conditions such as humidity are different, it is required to exhibit good slidability in order to ensure stable continuous production. For example, slidability is required for the container forming step production line or the container arranging line in the content filling step, even if the containers are in contact with each other or the container and the guiding plate, etc., the step or the next step is not affected. Work or production speed. Further, in the transport step line after the container is filled with the contents, the slidability between the conveyor belt and the container is required in order to ensure smooth conveyance. Further, in the container packaging line, since the container of the outer film is usually packaged at a high speed, the slidability between the surface of the container and the outer film is required. In such steps and production lines, environmental conditions such as temperature and humidity are different, so that the surface of the resin-made multilayer container under various environmental conditions is required to have appropriate slidability. Further, in order to improve the smudging property of the contents of the container, the slidability of the inner surface of the multilayer container is required for the resin. In order to improve the slidability of a resin multilayer container, a lubricant has been conventionally added to a raw material resin of the outermost layer or the innermost layer. Slip agent usually in batches

-6- 'S 201247485 method is added to the raw resin and mixed. As the slip agent, for example, fatty acid guanamine is widely used, and specifically, oleic acid decylamine, decylamine citrate, erucic acid amide, behenic acid amide, or the like. Among these, a lubricant having a lower melting point is, for example, decyl oleate, and by adding ceramide oleate, it exhibits good slidability when the temperature of the container is low. A lubricant having a higher melting point is, for example, decyl behenate, and by adding guanamine behenate, it is excellent in slidability when the container is at a high temperature when the contents such as food are filled at a high temperature. These slip agents may be used in combination of two or more kinds. For example, in JP-A-2009-214914 (Patent Document 4), a multilayer container filled with a non-oily content is disclosed in which a fatty aliphatic guanamine and a saturated fat are formulated in a polyolefin resin layer on the inner surface of the container. Alanine. Further, in Japanese Patent Publication No. 20-5-11-2, (Patent Document 5), oleic acid decylamine, decyl citrate and mustard are disclosed as a slip agent derived from natural oils and fats. Acid amide. Further, in the resin multilayer container, if the surface gloss is poor, there is a case where the state of the contents to be filled is intuitively grasped, and therefore improvement is required.

The α-olefin random copolymer (hereinafter sometimes referred to as "(A) Ziegler catalyst random copolymer) The propylene·α-olefin random copolymer known per se obtained by using a Ziglar Natta catalyst known as a catalyst for stereoregular polymerization of α-olefins. The Zieglernatta catalyst is well known as a catalyst for stereoregular polymerization of α-olefins, using a transition metal compound of Group IV-VIII of the Periodic Table of the Elements, and a typical example of the Ι-ΙΙ family of the periodic table. The organic compound of the metal and the catalyst which is preferably a third component of the electron-donating compound may be used in the polymerization of an α-olefin by any polymerization method such as a solvent polymerization method or a gas phase polymerization method. The Ziegler-Natta catalyst is exemplified by, for example, treating an aluminum-aluminum compound to reduce titanium tetrachloride obtained by reducing titanium tetrachloride or the like with an electron-donating compound, and further activating the titanium tetrachloride with an organoaluminum compound; 'A composition of titanium trichloride obtained by treatment with various electron donors and electron acceptors, and an organoaluminum compound and an aromatic carboxylic acid ester

The resin is extruded in a state in which the entire layer is composed of a specific layer, and the temperature of the die is usually from 120 to 240 ° C, preferably from 130 to 23 ° C, more preferably from 140 to 220 ° C. The shape of the hole can also be a flat shape close to a circular shape. If the coextrusion method using a tubular die is used, the wall thickness change control of the multilayer parison can be easily performed. A multilayer parison is produced by co-injection molding, and a molding machine having a plurality of injection cylinders is used to form a surface layer in a hole of a single parison injection molding die, and a molten layer is formed from a gate. The resin composition of the outermost layer and/or the innermost layer and the resin material forming the other layer are coextruded to form a bottomed multilayer parison. Part or all of the bottom of the multilayer parison may be free of barrier layers. Since the thickness of the portion is larger than the thickness of the body portion, the bottom portion is substantially only the thermoplastic resin composition layer, and the barrier property can be exhibited. By disposing the barrier layer only in the body portion, the mechanical strength of the multilayer container can be prevented from being lowered, and the uniformity is easy. Controlling the thickness of the barrier layer. 2. Blow molding blow molding is to hold a cylindrical multi-layer parison co-extruded by the above method with a detachable mold, so that the lower end is melt-sealed, and at the same time, the upper end is cut, and the upper end is blown from the upper end of the opening. After the pressurized fluid is formed into a container shape, 'cut off the unnecessary container-38-201247485 upper part of the mouth (head or bag part) to obtain a resin multi-layered container. For the mold for blow molding, a mirror-finished mold can be used. The surface temperature of the detachable mold is generally preferably in the range of 10 to 50 ° C. Moreover, the fluid for blow molding is preferably used for sterilizing air, and the pressure is preferably 1. 〇~15kg/cm2 range. The resin multilayer container of the present invention can also be produced by stretch blow molding. In the stretch blow molding step, the multilayer parison is adjusted to an extendable temperature, and then inserted into a cavity of a blow molding mold, and a pressurized fluid such as air is blown to perform stretch blow molding. An extension rod can also be used for extension in the length direction. The stretch blow molding can be carried out by either a hot parison method or a cold parison method. The total stretch ratio is usually 6 to 9 times, the pressure bottle is 8 to 9.5 times, and the heat resistant bottle is 6 to 7.5 times. The large bottle is about 7 to 8 times. When manufacturing a multilayer container made of a heat-resistant resin suitable for hot charging of contents, the temperature of the mold for blow molding may be raised to 1 〇〇 ° C or more in order to prevent heat shrinkage and deformation of the container during hot charging. Heat treated (heat set) in the mold. The mold temperature is 100 to 165 ° C, and the heat-resistant container is preferably 1 4 5 to 15 5 ° C, and the high heat-resistant container is preferably in the range of 1 60 0 to 1 6 5 ° C. The heat treatment time varies depending on the thickness of the multilayered container or the heat treatment temperature, and is usually from 1 to 30 seconds, preferably from 2 to 20 seconds.
