Description

200909515 IX. OBJECTS OF THE INVENTION: TECHNICAL FIELD The present invention relates to a resin composition, a film, a molded article using the film, an extended film, a heat shrinkable label, and a container to which the label is attached, and more specifically, The present invention relates to a resin composition comprising a polylactic acid-based resin and a polyolefin-based resin, and a film formed of the resin composition excellent in flexibility and transparency, and a molded article, an extended film, and a heat using the film. A shrinkable label and a container to which the label is attached. [Prior Art] Synthetic resin using petroleum as a raw material has been widely used because of its excellent characteristics and low cost, but since it is decomposed in a natural environment: low, and heat dissipation during incineration is large, in recent years, self-protecting natural From the environmental point of view, research and development of biodegradable polymers that can be decomposed by microorganisms present in the 'water' in the soil are being widely developed. : In biodegradable polymers, materials that can be melted into _ with high heat resistance and high strength: and: 溥 film, sheet, fiber and other aspects have been studied. The hard and brittle nature of lactic acid imparts impact resistance or softness. However, the refractive indices of the olefins are quite different, and the acid and the poly-polymer are mixed, and the inside of the resin composition is separated from each other to form a transparent material. It is difficult to make the interface of the moon, for example, in Patent Document i, it is disclosed that the PLA-based elastomer is PLA/P0- 90/1 60/4 〇 ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ 97121362 200909515 〃 (p〇), a resin composition and a molded body excellent in balance between hardness and flexibility are obtained. In the molded body, the flexibility is improved by mixing ethylene-propylene rubber and ethylene-octene rubber as the olefin-based elastomer in the polylactic acid to mix the rubber-vinyl butadiene rubber. However, in this case, the relationship between the crystallinity of the olefin-based elastomer to be used and the transparency of the obtained resin composition or molded article has not been studied and described: in addition, it is used in this document. In the case of the polylactic acid and the olefin-based elastomer, the resin composition or the molded article having excellent properties in both of flexibility and transparency is difficult to obtain. Further, Patent Document 2 discloses that lactic acid is the main component. A natural decomposable resin composition in which a component of 85% of an aliphatic polyacetate is mixed with 1 to 15% by mass of polypropylene: (spp), and the crystallinity of spp contained in the resin composition is revealed. It is lower than the conventional t propylene, and it can be used to impart softness, π H Μ , and ', and can impart polyolefin impact resistance. However, 'spp is based on lactic acid as Φ occupies VIII and In order to provide a full spear of the fatty polyester of the knife, the crystallinity of the polypropylene is still excellent in both the soft softness and the transparency of the gudin. The yang is difficult to make the other side The packaged body is used for various Various packagings have been developed for the use of y. For example, your helmet film is known to have high-strength film, ancient + for L flat thin, elastic film, and 牟 to polar front py film. , transparent film, A film, then adhere to &quot; electric f sheng Tao film, concealer film, heat-resistant film, resistant π 溥 film, gas barrier ~ mouth α 溥 film, 戎 兮 兮Composite film, etc. 4Combination of 1^Hai special binding film 97121362 200909515 These packaging films are distinguished by the characteristics of the respective constituent polymers, so they are used depending on the application, and it is difficult for one film to satisfy several characteristics at the same time. In general, for example, a film-like molded body formed of a dissimilar material such as polystyrene or polyethylene is bonded to a polyester film substrate to produce a polyester film substrate. Unobtainable characteristics such as strength, gas barrier properties, water resistance, moisture resistance, heat sealability, laminated film or sheet which are compensated externally, and the products obtained in this manner are mainly used as packaging materials, etc. The above is shaped by a different material When the film is bonded to each other, it is usually necessary to provide a subsequent modified layer, or to apply a tackifying coating agent, to dry the film thereon, or to insert a subsequent layer. For example, in the patent literature In the third aspect, the layered product in which the chlorinated polysulfonate-based resin layer is disposed between the layers of the polylactic acid-based resin layer and the polyolefin-based resin layer is disclosed. However, since the chlorinated polysulfide-based resin contains a layer, there is incineration. In the case of the environmental problem of the dioxin (Di0Xln), there is a problem in the environmental aspects such as Dioxin. In the case of Patent Document 4, there is disclosed a layer having a polyolefin resin as a forming tool and a polylactic acid resin as a main component. However, the shrinkable sheet is used as a shrink wrap film for conveniences and garnishes sold in convenience stores, etc., and is used as an inflation method. The heat shrinkable standard iron is used for *, and there is a problem that sufficient low temperature shrinkage is not obtained. In addition, since the shrinkable sheet is made of a polylactic acid-based resin layer as a core material and the two outer layers have a laminated layer of a resin layer, there is readability and solvent resistance in the case of a cylindrical sealed bag. Poor, not suitable for the problem of heat shrinkage mark 97121362 200909515 sign. In addition, when a recyclable resin (hereinafter also referred to as "recycled addition") which is produced by trimming shells and the like is added to the scrap of the shrink sheet, the polyolefin resin and the polylactic acid resin are used. At the interface, light scattering occurs, so there is also a decrease in the transparency of the film, and the method of obtaining a good:: the problem of clarity. In addition, if the shrinkage mark formed by the film is attached to the valley state, then there is a high shrinkage (for example, 30% or more follows the shrinkage of the film), and the intermediate layer and the front and back layers are stripped. The problem, in most cases, is in the design of a material that is in contact with a different material t. 'Use a compatibilizer that makes the two compatible. For example, in Lili 5, there is no = tree containing polylactic acid and modified dilute smoke compounds. The product, X, in Patent Document 6, also discloses a composition of a poly-salt resin comprising a poly-acid lactic acid other than polylactic acid, and a modified poly-smoke composition. The composition of the polylactic acid resin has the same strength and impact resistance, and can control the decomposition rate of the microorganism, but the modification of the reactive polar soil such as glycidyl group or maleic acid anhydride is used. The olefinic compound and the modified poly-saturated hydrocarbon compound act as compatibilizers, thus leaving the following name: „人课“1, that is, it will be produced during production, trial production, foreign matter, poor appearance, or filtration on the production line. 2, the device appears hole blocking, etc. 2 good phenomenon: When it is used as a film having a shrinkage property, the problem that the intermediate layer and the front and back layers are peeled off while the layer is not following the shrinkage of the film is not solved.

Further, when it is mixed with the polylactic acid-based resin (B), it is possible to obtain a co-continuous structure relatively easily by blending the mixing ratio or the melt viscosity, etc., and it is preferable to use methyl (meth)acrylate. As the segment (b) of the compatibilizer (C) of the present invention. The copolymer structure of the compatibilizer (C) may, for example, be a structure of a block copolymer, an alternating copolymer, a random copolymer, or a graft copolymer, preferably a segment constituting the compatibilizer (C) (a) And the segment (13) is bonded to the block copolymer or the random copolymer at the end of the molecular chain because the segment (4) 2 segment (b) is bonded to each other in a state of being bonded by a covalent bond. The interface between the polylactic acid-based resin (1) and the polyphase which are incompatible with each other is different from the interface of the polylactic acid-based resin (1) / X-olefin resin (B), and the interface is Decreasing and increasing the thickness of the interface, thereby suppressing large agglomeration as a main stem and in which the 'graft copolymer has a comb structure having a segment (8) as a branching component in the segment (a) and (4), ... body (4), infiltrated into the polylactic acid resin (1) phase and the polyolefin resin 9721362 27 200909515 hydrocarbon resin (B) phase interface is not easy to fall off, and easy to adhere to the phase interface, so the effect of stabilizing the dispersed phase Large, so better. In the case where the compatibilizer (c) is a graft copolymer, the mass average molecular weight of the ethylene-based polymer forming the segment [in tetrahydrofuran (THF), gel permeation chromatography in terms of styrene-based styrene ( The measured value obtained by Gpc) is usually in the range of 1,000 to 2, 0 〇〇, 〇〇〇, preferably 5, 〇〇〇 1 1 200, 〇〇〇. When the mass average molecular weight is less than 丨, when 〇(10), the plant has a tendency to decrease the heat resistance of the graft copolymer. When the mass average molecule 1 exceeds 2,000, 〇〇〇, the melt viscosity of the graft copolymer is exhibited. High, the tendency to formability decline. Usually, a molded article composed of a resin composition containing a polylactic acid-based resin and a polyolefin-based resin forms a phase-separated structure. At this time, a sea-island structure is formed in which, in terms of the volume percentage of the whole, there are many components in the matrix phase and the other component in the dispersed phase. However, in the second film, after confirming the phase structure by SEM observation from the TD direction (direction perpendicular to the flow direction of the resin) I, it was confirmed that the second film was formed into a polylactic acid-based resin (A) and a polyolefin system. Resin (B) is a co-continuous structure of intricate interlacing. In the second film formed of the mixed resin composition of the polylactic acid-based resin (A), the polyolefin-based resin, and the compatibilizing agent (C), when the above-described co-continuous structure is formed, a common island structure is formed. In the case of the above, the interlayer adhesion of the (I) layer and the (melon) layer in the second film described below can be improved. The formation of the co-continuous structure takes into consideration the volume fraction, melt viscosity, and resin between the mixed polylactic acid-based resin (A), the polyolefin-based resin (B), and the compatibilizer (c) in the mixed resin composition. It is adjusted by compatibility and the like. 97121362 28 200909515 The ratio of the segment (a) of the compatibilizer (C) to the segment (b) affects the compatibility of the polylactic acid-based resin (A) and the polyolefin-based resin (B) during mixing. . The co-continuous structure in the resin composition composed of the polylactic acid-based resin (A) and the copolymer (c) is a continuous phase containing a polylactic acid-based resin (A) as a main component, and a copolymer (c) The middle segment (a) is composed as a continuous phase of the main component. The copolymer (C) is composed of the segment (a) and the segment (b). When the composition ratio of the segment (a) is high, the compatibility with the polylactic acid resin (A) is insufficient, so that it is easy. The island structure is formed and it is easy to cause insufficient mechanical properties or transparency. Further, when the composition ratio of the segment (a) constituting the copolymer (c) is low, the obtained resin composition becomes hard and brittle, and it tends to cause insufficient mechanical properties. Thus, when the composition ratio of the segment (a) to the segment (b) in the compatibilizer (c) (mass ratio in the structure) is (a) + (b) 〇〇, if the segment When the composition ratio of (a) is 99 to 10, a co-continuous structure is easily formed, and the obtained resin composition is excellent in mechanical properties and the like, which is preferable. In the present invention, the composition ratio of the segment (a) is more preferably 95 to 15, more preferably 90 to 20. The melt flow rate (MFR) or melt index (MI) of the compatibilizer (c) is preferably 〇1 g/10 min or more, more preferably 01 g/1 〇 min or more, further preferably l. More than g/l 〇 min, and is 5 〇〇 g / 1 〇 min or less, preferably 300 g / l 〇 min or less, more preferably 2 〇〇 g / 1 〇 min or less. This MFR was measured in accordance with the method specified in JIS7210 under the conditions of a resin temperature of 23 ° C and a measured weight of 21.18 N. If the MFR is in the range of 0.01 g/10 min or more and 500 g/l〇min or less, a good affinity of the compatibilizer (C) and the polylactic acid-based resin (A) will be obtained. 97121362 29 200909515 When two or more resins are used as a compatibilizer ((:), the compatibility between the polylactic acid-based resin (A) and the polyolefin-based resin (β), and the transparency of the daily fat , viscoelasticity, etc., to adjust the blending ratio. For example, = use of the above graft copolymer, modified benzene, aromatic sulphur, sulphate hydrocarbon copolymer, aromatic vinyl hydrocarbons and a total of vehicles Diene: a hydride of a polymer, or a copolymer in which a polar group is introduced as a mixed resin. When two or more kinds of compatibilizers are used, a bovine polylactic acid resin (A) and a poly The compatibility of the olefin-based resin (3) = the transparency of the film is preferred, and the polymerization method for producing the compatibilizer (C) can be carried out by a commonly known bond transfer method, ionization stun irradiation method, or the like. Any one of the methods, however, in the polymer constituting the segment (4), the monomer (monomer) constituting the segment (7), the specific radical (co)polymerizable organic peroxide, and the radical polymerization of the hydrazine are added. Starting agent, and kneading the segment (b) monomer in the segment (a) polymer Thereby, the production method of the grafting reaction is carried out, because the simple 'grafting efficiency to the 'no secondary aggregation of the segment (8) due to heat' is easy to use the compatibilizing agent (c) and the polylactic acid resin (Α It is preferred that the interaction of the phases is excellent. On the one hand, in the second film, the mixed polylactic acid resin (Δ), polyolefin resin (Β), and copolymer ((:) melt flow rate (Μ)) will become 幵v It is important to add J1 and form a continuous structure, and if it is small, the expansion of the molten resin used in the film at the time of extrusion becomes uneven, and thickness unevenness is likely to occur. On the one hand, if the MFR is large, the formability at the time of extrusion processing is lowered, and the progress of the article 97121362 30 200909515 is also lowered. Further, at the time of melt-kneading, the kneading of the resin tends to become uneven, so that It is sufficiently compatible to form a co-continuous structure. Therefore, the polylactic acid-based resin (A), the polyolefin-based resin (B), and the MFRCJISK 7210 of the copolymer (C) in the second film have a temperature of 19 (TC, The weight is 21. 18 N) is 〇. 5 g / l 〇 min or more, preferably 〇 · 1 g / i 〇 min or more, more preferably 0.2 g/10 min or more, and 20 g / 10 min or less, preferably 10 g/l 〇 min or less, more preferably 5 g/l 〇 min or less. In the second film, The ratio of the smelting viscosity of the mixed polylactic acid-based resin (A), the polyolefin-based f ^ resin (B) and the compatibilizing agent (C) has an important influence on the formation of a co-continuous structure. When the melt viscosity differs greatly, When kneading at the time of melt-kneading, the kneading of the tree sputum becomes uneven, so that it is not sufficiently compatible, and a co-continuous phase is hardly formed. Therefore, in order to form a co-continuous structure, it is necessary to lower the mixed polylactic acid-based resin (A). The difference in melt viscosity between the polyolefin resin (β) and the compatibilizer (c). From the viewpoint of forming the co-continuous structure, the polylactic acid-based resin (A) and the polyolefin system in the first film are used. The melt viscosity ratio (α)/(β) and (a) calculated from the respective melt viscosities of the resin (β) and the phase (C) (JIS Κ-7199, using a capillary rheometer, temperature 200 ° C) And / (C) must be 0·0 5 or more and 1 〇 or less, preferably 〇1 or more and 7 or less, more preferably 0.2 or more and 5 or less. Polylactic acid-based resin (A) in the first film, The mass ratio of the polyolefin resin (β) and the compatibilizer (C) is (A)/(B)/(C)=0 to 80/0 to 50/1 to 1 Torr, preferably (A). ) / (B) / (C) = 15 ~ 70 / 0 ~ 50 / 3 ~ 70. Among them, the mass ratio (A) + (B) + (C) = 100. The formation of a co-continuous structure will be mixed The effect of the blending ratio of the resin. Usually, in order to form a co-continuous structure, the important resin composition of 97122362 31 200909515 is similar to each other. As the difference is increased, the phase structure will be self-coupling.

For example, when the heat-shrinkable film is attached to the direction of the #, J-circle direction, the so-called "positive side: the time means the equivalent of the parent direction of the bottle" is the direction of the main contraction direction 97121362 48 200909515 . The heat shrinkage rate at the above temperature is an index for judging the adaptability of the shrinkage label and the shrinkage label for a relatively short period of time (a few seconds to a few seconds or so of a contraction plus one step). For example, the heat shrinkable film of the shrink label of the PET bottle is required: the rate varies depending on the shape, but is usually m or more and (4) or less. ** Also, as the current f When the label of the special bottle is used, the shrinking machine in the industry uses steam as the heating and shrinking machine for shrinking processing. In addition, the heat is applied to the object to be coated:: 'The heat shrinkable film must be as much as possible The low temperature knife shrinks. However, when the temperature dependence of the film is high and the shrinkage temperature is extremely different, it is easy to cause a shrinkage behavior due to the steam shrinkage_the temperature of the household, so there is uneven shrinkage.

In terms of the +* productivity, if the thermal shrinkage of the film is above: the condition is within the condition of shrinkage processing It is better to cover the object and obtain a good shrinkage finish, uneven shrinkage, wrinkles, and unevenness. tt ^ ^ ::# m ^ ^^ * - The water in the coffee water is heated ίο second, longitudinal (with The shrinkage ratio of the main shrinkage side and the direction of the main shrinkage is preferably 10% or less, more preferably 5% to: the taste advancement step is preferably 3% or less...heating in the warm water of 7rc is 10 The ratio is preferably 10% or less, more preferably 45% or less, and further 97112362 49 200909515 is more preferably 3% or less. Among them, if the heat shrinkage ratio of the film in the direction orthogonal to the main shrinkage direction is 10% or less, shrinkage is performed. The dimension in the direction orthogonal to the main contraction direction is not easily shortened by itself, and the printed pattern or the text after the contraction is less likely to be deformed or the like, and when it is an angular bottle, it is less likely to cause a problem, and thus it is preferable to exhibit the present invention. In the case where the first to third films are used as the heat-shrinkable film, the tensile elastic modulus in the direction orthogonal to the main shrinkage direction of the film is preferably UO MPa or more, more preferably u〇. 〇 MPa or more.

In general, the natural shrinkage ratio of the heat-shrinkable film is preferably, for example, 3 (300% or less after 30 days of storage, the natural shrinkage rate is 1.5% or less, preferably 丨.0% or less. Under the above conditions: natural shrinkage rate When it is 5% or less, even if the film produced is stored for a long period of time, it can be stably attached to a container or the like, and it is not easy to cause problems in practical use. The first to third films of the present invention will be used.

If the tensile elongation at break in the environment is more than or equal to 2, it is less likely to cause defects such as film breakage during the steps of printing, bag making, etc. Further, even if the speed of the step is increased with the steps of printing, bag making, etc., when the tension applied to the thin is increased, the film is hard to be broken as long as the tensile fracture occurs, and thus it is more preferable. The first to third films of the present invention are used as heat shrinkable thinner When the film is sealed at a strength of 3 Ν/15 or more, it is preferably 5 μ wide or more. Moreover, the value of the strength between the layers (4) is not particularly high (4), and when it is ππη wide or more, when it is used and when it is thermally shrunk, And the problem of peeling and the like between the film layers, in part, to the third film, made in the hunger, the first% of the invention, under the model stripping 97121362 51 200909515 method along the TD direction to 200 When the measurement is carried out by the method of peeling at the test speed of /min, the obtained sealing strength is at least 5 N/15 _ wide or more, and the peel strength at least exceeds 2 N/15 mm t, so that between the sealing portion and the film layer It is also difficult to produce the peeling.

The form of the laminated body can be either a flat shape or a tubular shape, and the production can be produced. The width direction of the entire film may be preferably planar in terms of printing on the inner surface.
