Description of the Invention: [Technical Field of the Invention] The present invention relates to a polyolefin film, and more particularly to a polyolefin film for producing a soft bag. [Prior Art] Existing medical soft bags, such as drip bags or infusion soft bags, are mostly made using sputum molecules as raw materials, because soft bags made of polymers have small volume, can be curled and are easy to use. The advantages of acceptance, light weight and low price are widely used in the medical profession. The medical soft bag is usually formed by heat-melting and melting a thin smoke film. Because medical soft bags are used to hold liquids that are to be input into the human body, such as liquid medicine or blood, etc. Generally speaking, in the case of high-molecular materials - polyvinyl chloride (PVC) and polyolefins as soft bags, polyolefins are: a preferred choice because PVC materials need to be added as softeners. Di(2-ethylhexyl) vinegar (DEHP for short), and the release of DEHp will cause children to have premature and unsound conditions such as physiology, and when chlorinated, it will produce toxic substances. In comparison, the polybasic hydrocarbons do not release the plasticized material contained therein into the liquid they contain, and have higher safety. In addition, the medical soft bag must also be able to withstand the high temperature before use (about 121. (7) sterilization, and the soft bag should also have high transparency, softness, impact resistance, low temperature, water and water vapor Equivalent quality, so the existing soft bags are mostly made of multi-layer = polyolefin film as the main body, in combination with the characteristics of the layer to the purpose, so that the resulting soft bag presents a full range of functionality. , but often also 0 201119862 can not balance all the performance. - For example, the mainland patent publication CN1666856A discloses a multilayer film based on polyolefin, which is composed of an outer layer, a main layer and an inner layer. A multilayer film comprising: the outer layer is a polypropylene homopolymer modified by one or more impact modifiers, the host layer being a polypropylene modified with one or more impact modifiers a terpolymer and/or a polypropylene-based random heterophasic copolymer, and the inner layer is composed of one or more impact modifier-modified polypropylene terpolymers and/or polypropylene copolymers. And used in the case The impact modifier is selected from the group consisting of a styrene ethylene/butene segment copolymer, a styrene ethylene/acrylic copolymer, a polyhexene copolymer or a polyethylene plastomer. However, due to the multilayer film The middle, and the similarity 'so that the melting point between the layers has only a small temperature difference, so when the inner layer is melted, the outer layer melts easily, resulting in a stable and fast turn in a large number of bags. Performance. There are already many soft bags with different materials, but based on the above, it is necessary to continue to develop new thin smoke film, especially only a single one can produce a variety of basics acceptable to the medical community. The function of the soft bag, prepared:::: the desired, because compared to the multilayer film, the single layer film is more convenient in the film blowing machine, and the price of the general three-layer film blowing machine is a single layer. The production cost of the single-layer film is 3 to 5 times, so the production cost of the single-layer film will be lower. Therefore, there is still a need to develop ψ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Therefore, the present invention is intended to provide a property Industry 201119862 The application of standard and easy to make polyolefin bags of soft bags.
