Definitions

  • the chemical liquid packaging bag is required to have flexibility such as crushability, transparency that can easily observe the state of use of the solution, heat resistance, heat sealability, drop impact resistance, etc., and drug stability that can withstand high temperature sterilization.
  • the medical sap bag of the general sap bag is formed by bonding the two layers of the film through the thermal bonding, for this purpose is produced by melting the raw material of the inner layer and sealing under conditions that heat and pressure is applied outside the outer layer.
  • the blocking phenomenon due to the adhesion of the film inner layers during high temperature sterilization occurs when the Tm of the inner layer is low and the viscous behavior becomes strong at the sterilization temperature (during viscoelastic behavior of the polymer).
  • the raw material having a high Tm has good affinity between the raw materials constituting the inner layer, it occurs when the surface energy at the interface is small and the inner layers adhere to each other.
  • the term 'polypropylene' is made using only propylene monomers, and includes all polypropylenes having isotactic, syndiotactic, and atactic structures.
  • a melt index (based on ASTM D1238) of 7 to 9 g / 10 minutes, a density of 0.85 to 0.95 and a softening point of 145 to 165 ⁇ are used.
  • polyethylene which is one of the components of the inner layer 6, is a component that makes the multilayer film have antiblocking property. If the content is less than the above range, it is difficult to realize antiblocking property. It leads to degradation.
  • fusing point of the outer layer 2 is 145-165 degreeC
  • middle layer 4 is 140-155 degreeC
  • the inner layer 6 has the range of 125-140 degreeC.
  • Medical multilayer film according to the present invention is not particularly limited in the present invention, it can be produced using a method known in the art.
  • the multilayer film is capable of co-extrusion and lamination of the film and the film.
  • the anti-blocking property was checked after the three-side sealing of the film (100 X 120 mm), filled with 50 mL of distilled water, after sealing the remaining one side at 121 ° C. for 30 minutes under high temperature steam sterilization.

Abstract

La présente invention a pour objet un film médical multicouche et son utilisation, et plus particulièrement un film médical multicouche comprenant : une couche externe comprenant un type de polymère de polypropylène choisi dans le groupe comprenant le polypropylène, un copolymère de polypropylène, et leur combinaison ; une couche intermédiaire comprenant de 50 à 70 % en poids d'un type de polymère de polypropylène choisi dans le groupe comprenant le polypropylène, un copolymère de polypropylène, et leur combinaison, et de 30 à 50 % en poids d'un élastomère thermoplastique ; et une couche interne comprenant de 95 à 99,9 % en poids d'un type de polymère de polypropylène choisi dans le groupe comprenant le polypropylène, un copolymère de polypropylène, et leur combinaison, et de 0,1 à 5 % en poids de polyéthylène. La présente invention concerne aussi l'utilisation du film. Le film multicouche présente une excellente transparence, une excellente résistance thermique, et d'excellentes propriétés de scellage, et empêche un phénomène de blocage dans lequel les couches internes des films se collent les unes sur les autres pendant une stérilisation à haute température. Par conséquent, le film multicouche de la présente invention peut être utilisé dans des réceptacles pour sève pour l'emballage et l'administration d'un liquide médical tel que la sève ou le sang, des poches médicales, des récipients pour produits de contraste et des récipients pour le sang.
