Definitions
- the present invention relates to the field of polymer science and technology with special emphasis on the production of sterilized plastic packaging for products that need to be sterilized, especially medical products.
- a medical packaging is a sterile packaging, commonly made of plastic, with good barrier to microbes or other contaminates to maintain the sterility of medical devices inside after the sterilization process.
- the medical packaging in the market are classified into 2 categories according to their pore structures as follows: (1) A Non-Porous Medical
- Packaging which is commonly made from commoditized thermoplastic polymers such as but not limited to, polyethylene, polypropylene in variety of grades as homopolymers, copolymers, heterophasic polymers, and blends thereof, processed by an extruder such as, but not limited to, blown film extruder, T-die cast film extruder, or calendaring extrusion to form either single- layered, or multi-layered film-liked substrate that then further fabricated to be a medical packaging. Without any opened dead pore, non-fibrous web contained structure, these types of medical packaging give an excellent barrier property in protecting medical devices inside.
- a Porous Medical Packaging which normally consist of randomly laid webs that contain opened dead pores. The pores allow sterilant gases, such as ethylene oxide or steam, to permeate through its structure. This type of medical packaging can undergo more sterilization methods than the one mentioned above.
- the web has a broad pore size distribution and variety of shapes which may cause more risks of losing their sterility as some microbes, impurities, or contaminants can penetrate through the packaging via its over-tolerance, big pores.
- the medical packaging with fibrous webs can be further classified into 2 categories according to the types of fibrous materials as follows: (2a) Medical packaging with a paper web made of natural fibers of wood pulps or plants fiber like cotton fiber, whose chemical structures mainly are cellulose. Cellulose is sensitive to water so it likes to absorb water that will diminish its physical strength, and is spoiled by microbes that consequently lead to losing their barrier functionality and sterility; and (2b) Medical packaging with a thermoplastic fiber web, especially a high density polyethylene web, which can eliminate the disadvantage of a natural short fiber kraft paper described above. Nevertheless, some drawback about bonding and opening the packaging is concerned.
- High temperature, high pressure water vapor in a steam autoclave is the most common method to sterilize medical instruments or devices that can withstand high heat conditions such as forceps or other stainless steel devices by exposure to 121 - 134 degree
- Ethylene oxide gas is most widely used as chemical sterilant permeating through a porous packaging to sterilize medical devices inside. This process is suitable for heat or moisture sensitive articles such as electronic or low melting point plastic and rubber parts or devices.
- the first packaging with densed structure has an excellent barrier property to keep its sterility, but cannot undergo all methods of sterilization, especially by sterilants that adequate porosity is an essential factor, so a gramma radiation is an alternative method which has some drawbacks like much more rigorious safety controls in sterilization plant, radio-active accident concerns, that limits the use of this type of packaging, while other plastic sterile medical packaging, comprising fibrous webs, either a natural celluosic kraft paper or a synthetic thermoplastic webs, enable sterilization by steam or ethylene oxide gas, which are much more versatile to process safely even in a general hospital. Nevertheless, its versatility to sterile with all common sterilizations methods is sacrifice with its worse barrior function.
- the present invention is related to a sterilizable medical packaging with living pores comprising a set of living pores, wherein the packaging is preferably a plastic film packaging, but without any open dead pores or containing non-fibrous web made of semi-crystalline polyolefin materials.
- the most common thermoplastic materials used in plastic packaging are polyethylene, polypropylene, polybutylene, and especially isotactic polypropylene which is used as main raw material.
- the sterilizable medical packaging with living pores therefore, comprises a unique formulation of polyolefin blend with specific additives are proposed.
- a blend of polyolefins such as, but not limited to, polyethylene, polypropylene, polybutylene, copolymer of C2-C8 alpha olefins, preferably comprising at least
- isotactic polypropylene homopolymer most preferably high molecular weight, high crystallinity isotactic polypropylene homopolymer with low melt flow index of less than 5; a functional additive comprising 100-2,500 ppm of nucleating agent such as, but not limited to, sorbitol derivatives, 1,3,5-benzenetrisamide derivatives, which can induce very fine crystalline lattices of isotactic polypropylene that toughens the packaging structure by increasing tensile strength of the film substrate, especially in transverse direction, while their percentage of elongation remains high; and 0.1-2 percent by weight of hydrophilic filler selected from silica with average size of 5 microns or less, polyethylene oxide with molecular weight of more than 1 ,000 or blends thereof to provide amphophilic paths improving gas permeability, especially water-vapor transmission rate (e.g. in one embodiment, the water vapor transmission rate of said packaging at modified negative pressure, 45 kPa
- the above compound mixtures are heated and plasticized with 180 -250 °C in an extruder, such as, but not limited to, a blown film extruder to form a film-like substrate material with a cooling rate in range of 1 - 10 °C/second, and undergo common process, similar to other packaging, such as treating with corona discharge, printing, slit sealing and cutting, to become a sterilizable medical packaging with living pores according to this invention.
- an extruder such as, but not limited to, a blown film extruder to form a film-like substrate material with a cooling rate in range of 1 - 10 °C/second
- the resulting sterilizable medical packaging with living pores has a unique structure that gives an excellent barrier to microbes or other impurities as its structure has excluded the open dead pores.
- the ratio of tensile strength of said packaging in transverse direct per machine direction is greater than 0.7.
- the ratio of an elongation of said packaging in machine direction per transverse direction is greater than 1 , and the elongation in machine direction is greater than 200%.
- heterophase structure in one embodiment, comprising a rigid tough network of crystalline lattice of isotactic polypropylene, which attributes the overall strength of the plastic packaging, meanwhile the other soft, elastic amorphous region that disperses all around the interface of the crystalline network plays a main role in gas permeability.
- a rigid, tough crystalline network and a soft elastic amorphous interface gives this unique heterophase structure an extraordinary physical property and performance similar to having a set of living pores.
- the resulting sterilizable medical packaging with living pores will provide a good barrier where it can be stored in common atmosphere or open air, but under controlled pressure in sterilized chamber, especially in negative pressure during evacuation process, the interstitial volume between crystalline interface will enlarge, enabling the sub-micrometer pores that are dispersing thoroughly through the matrix to allow water vapor or sterilant gas to permeate through the packaging to sterilize any products that need to be sterilized, such as medical products.
- this sterilizable medical packaging with living pores according to this invention will prolong the product shelf life and give a better performance in maintaining sterility even in severe conditions like in war services or field applications.
