Description

Λ S 7 937 A7 ____B7____ V. Description of the invention (1) [Technical field to which the invention belongs] (Please read the precautions on the back before filling this page) The present invention relates to styrene resin blown films, laminates and containers In more detail, a resin composed of a styrene-based polymer having a syndiotactic structure (hereinafter, simply referred to as "syndiotactic polystyrene" or "s PS") or a resin composition thereof SPS blown film of specific properties, and laminates and containers, particularly heat-resistant oily foamed containers having a layer composed of the blown film, a styrene resin foam layer, and a styrene resin layer. [Previous technology] Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs in recent years, with the changes in food and beverage life, processed foods such as bento and sheet vegetables are reheated for processing, and are packaged in such foods. In this case, a container made of various resins is used. In addition, such processed foods are mostly edible oil-based for conditioning, and there are also cases where the container into which processed foods are placed is directly heated by an electric oven or the like. Therefore, the resin used in packaging materials for such processed foods is required to have high heat resistance and heat resistance to oil. In addition, it is also expected that the heated and conditioned container is held empty-handed, so a resin with excellent thermal insulation and rigidity is sought. Furthermore, for these resins, from the perspective of environmental care, they also seek to have recyclability that is both reusable. Previously, such materials were sheets or foams made of polypropylene resin and PET, and sheets or foams made of polystyrene resin and heat-resistant polystyrene resin. Coated heat-resistant sheets, or general polystyrene-based resins and heat-resistant polystyrene resin foams, etc., and general polystyrene-based films, polystyrene paper standards applicable to Chinese National Standard (CNS) A4 Specifications (210 X 297 mm) -4- 467937 A7 B7 V. Description of the invention (2) Laminates of ethylene copolymer film or polypropylene film, etc. (Please read the precautions on the back before filling out this page.) However, although polypropylene resin sheets and PET sheets are excellent in heat resistance and heat resistance, they have poor thermal insulation and cannot meet the above requirements. In addition, although general polystyrene-based films, sheets, and films of polystyrene copolymers are good in heat lamination, thermoformability, and recyclability, they have the disadvantages of insufficient heat resistance and oil resistance. In addition, although a laminate of a polystyrene sheet and a polypropylene film is excellent in heat resistance and oil resistance, since it requires an adhesive, it has a problem of insufficient recyclability. In particular, the collection of processed foods using coconut oil with excellent oxidative stability and digestibility as processed food oils and processed foods using this coconut oil as raw material medium chain glyceride (MCT oil), if made of the above materials Since the container has insufficient heat resistance and oil resistance, problems such as cracks in the container occur. However, although it is known that syntactic polystyrene (SPS printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economy) has high crystallinity, and is excellent in heat resistance and oil resistance, the high crystallinity SPS Insufficient thermoformability and, when laminated as a thin film, have the disadvantage of becoming a substance with insufficient hot-lamination adhesiveness. Moreover, the stretched film in SPS is also insufficient in thermoformability, and it is difficult to use it for containers by thermoforming. For example, it has been proposed that a laminate of SP P and foamed SP be a material having excellent heat resistance, oil resistance, and recyclability (Japanese Patent Application Laid-Open No. 5-269907). However, the SPS layer used has high crystallinity and is easy to peel off because of its poor thermal lamination and thermoformability. Furthermore, the stress via the foamed layer is relaxed during heating, and it has the disadvantage of being easily deformed. Also, 'The laminated body of SPS and polystyrene resin sheet with low crystallinity has been proposed to have good thermoformability. After thermoforming, the crystallinity of the SPS layer is increased.' This paper size applies the Chinese National Standard (CNS) A4 specification ( 210 X 297 mm) -5- 467937 A7 B7 V. Description of the invention (3) (Please read the precautions on the back before filling in this page) It has a Furon effect (Japanese Patent Application Laid-Open No. 5-1 1 1 9 8 4 Gazette). However, because the SPS with low crystallinity is not a blown film, it has a small extension, and the thermoformed container also has the disadvantage of poor mechanical properties. [Problems to be Solved by the Invention] The present invention is based on the above viewpoint The invention is practiced to provide a blown film with excellent processability and adhesion, thermoformability, and surface punching properties at the time of hot lamination, and a laminated body with excellent thermoformability, oil resistance, and recyclability, and The container formed from the laminate is used for this purpose. [Means to Solve the Problem] The inventors of the present inventors have repeatedly studied, and found that a low-crystalline polymer composed mainly of a styrene polymer having a syndiotactic structure and a resin composition containing the polymer The specific blown film is excellent in elongation at break, heat resistance, heat resistance, heat lamination, and thermoformability. The laminate obtained by using such a resin material is excellent in recyclability and thermoformability, and is therefore suitable for Printed as a container forming material by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs.

Properties of syndiotactic polystyrene or the resin composition containing it Syndiotactic polymerization used in the molding of styrene resin blown film of the present invention In styrene or its i-containing resin composition, the following properties must be satisfied: (1) The melt flow index (M I) measured at a temperature of 300 ° C and a load of 2.16 kg (10 minutes) is 0 5 or more and 20 or less, preferably 1 or more and 15 or less. When the MI is less than 0 · 5, the appearance of the film, which is poor in extrusion formability and is liable to cause melt fracture or the like, is poor. In addition, when the M I exceeds 20, foaming becomes unstable, blow moldability is deteriorated, and the thickness uniformity of the obtained film is poor. Not only the surface is prone to wrinkles, but it is difficult to obtain an orientation effect through blow molding. Elongation at break and film impact are not sufficient.

(2) The crystallization temperature is less than 2 36 ° C, preferably less than 230 ° C. The so-called crystallization temperature (T c) printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs refers to the use of a differential scanning calorimeter ( DSC), the crystallization peak temperature when the temperature is reduced from 300 ° C to 20 ° C / min.

(2) The sum of the elongation at break of the film in the longitudinal direction and the transverse direction is 15% or more, preferably 20% or more. If it is less than 15%, the thermal lamination processability is appropriate, the mold reproducibility during hot forming is likely to be poor, and the surface impact of the hot formed product may be reduced. (3) Although the thickness of the film is not particularly limited, it is usually 1 to 300 m, preferably 20 m to 20 m. If it is less than 10 #m, the heat resistance oil may be insufficient. If it is more than 3 0 #m, the stress during heating will be relaxed, and when it is used in a heat resistant oil container, the container may be deformed. 5. A method for producing a styrene-based resin blown film of the present invention Although it may be performed by using a known blow molding, suitable specific methods include the following methods. First, syndiotactic polystyrene or its composition is melt-extruded from a ring-shaped plate at 2700 to 320 ° C. The screw used here can be uniaxial or biaxial. Either type, and the opening degree of the ring-shaped plate is preferably 0.5 to 2.0 mm. The extrusion direction from the template here can be any of the upward direction (upward blowing) and the downward direction (downward blowing). Alas, the exit speed of the template can be adjusted by selecting the amount of extrusion and the diameter of the template and the gap of the template, and it is preferably 1 m / min or more.
