In the past year and a half, some of the main high
High-tech, highly layered flexible film for barrier food packaging has been eligible for the first coextruded film for medical packaging.
Most of the food
Film companies already have a small medical film business that has been trying to apply their low for years
Experience in cost production, economies of scale and highly hierarchical structure of the medical market.
Now, in this case, they are becoming factors that need to be considered --
Professional price business.
Medical Packaging film is said to grow at a rate of 2% to 4% per year, similar to food packaging, but faster than the overall economic growth.
Medical packaging is also considered a safe business.
\"Once you get in, you get in,\" explains an executive at a large healthcare packaging provider.
Replacing suppliers requires the equipment manufacturer to re-certify its products to the FDA.
\"You are unlikely to lose your business unless you do something bad.
\"The requirements for medical packaging are very different from those for food packaging.
In order to preserve processed meat and cheese, a flexible food package must provide a tight oxygen barrier.
Extruded film for medical packaging-
Film and disinfection protective bag mainly used for medical devices and hospital supplies-
Microbial barriers must be provided to resist puncture and survive after sterilization.
Food film companies bring expertise in highly layered structures.
Crowding together reduces costs in several ways.
It can replace expensive materials and use rosins more effectively.
In some cases, it can also reduce the number of production steps by eliminating the coating or lamination.
Highly layered medical forming film can have PE-tie-nylon-tie-PE-tie-nylon-tie-
PE, or the same structure can be replaced with PP nylon.
2 to 16 miles thick.
Most are six to nine miles.
Of these films, nylon is used only for puncture strength.
EVOH is not used in medical packaging because no oxygen barrier is required.
The two most common sterilization methods are ethylene oxide gas and radiation.
The breathable part of the package, usually medical paper or DuPont\'s Tyvek non-woven fabric, allows ethylene oxide to enter and exit. (High-
The temperature autoclave, steam or hydrogen peroxide plasma is also used-
Hospital disinfection, but most of the packaging does not apply. )
Up to now, the thermoforming film of the device package bottom network is usually three-
Layer extrusion of EVAionomer-
EVA or poly surrounded by EVA/PE mixture layers.
Although the Poly is hard and clear, it is expensive.
If you need a heavier specification to form or bag film, three-
The EVA/Poly blown film usually collapses to form six layers by itself.
Top lidding is usually a combination of paper/plastic/foil produced by extrusion coating and lamination.
This separate site provides specific Open features.
For example, syringes for ambulances and first aid
Room use must pop up quickly.
Other covers must be opened slowly.
The sterilized bag is a transparent bag with a linear tear at one end.
There are usually three bags.
Layer structure of EVA and Poly.
The Poly provides linear-tear feature.
If gas sterilization is used, most bags will have a breathable patch or header strip made of Tyvek or paper.
No linear tearing is required for bags with headlines, so single-layer llonomia or multi-layer
Layer olefin film can be used.
In the past two to three years, nylon, as a way to reduce the cost of packaging, has slowly replaced the Poly to form a film.
Since the nylon needs to tie the ribbon layer to stick to the PE seal layer, the number of layers will automatically increase.
Three years ago, munam\'s health care flexibility at Mundelein, Ill.

The basic film was launched in 2001.
The film offers customers the option to measure down-
For example, from 12-mil, three-
10-layer film with Polymil, five-
Layer film with nylon.
Over the past 18 months, the number of layers of these films has grown rapidly, as several companies have qualified for the top eight companies, nine-, and 11-
The membrane of medical application.
This highly layered film is still only a small factor in the market, but they reduce the packaging cost of some commodity medical products, such as glove packaging, which is usually more expensive than the products it contains.
Such novelty is shaking a Conservative club market that has been resisting change. Several food-
The packaging giant is the main reason to introduce these productslayered films. Winpak Ltd.
In Winnipeg, Manitoba, its first medical packaging film is a nylon --
Based on the 11-layer structure, it is used for the manufacture of disinfection bags.
This is probably the most highly layered coex film in the world\'s medical packaging.
Winpak won\'t recognize its structure, but the film is in 11-
Extruder flow extension film line, originally used as a barrier film for thermoforming food packaging.
Recently, Winpak has provided qualified highly layered blow films for medical packaging that are manufactured on the production lines of eight and nine extruder in Senoia, Ga. , plant.
\"We have created some interesting new options,\" said David John, president of packaging at winpark, Winnipeg.
Winpak aims to expand its medical business by applying the technology of coex barrier food packaging to reduce the cost of medical molded films.
\"We have been working behind the scenes for three years, have conducted qualification reviews on several applications, and are evaluating several other applications, using some new
Power generation materials such as metal can save costs.
We found the medical market open to new things.
\"The medical market will be as competitive as other packaging markets,\" he predicted . \"
Winpak has a sister company in Finland called Wipak, the world\'s leading producer of high-tech products
Technology packaging film.
Wipak\'s medical film expertise in Europe helps to obtain validation of the new structure from North American regulators, said Heikki Weijo, managing director of medical packaging for Finnish Nastola Wihuri wiwiwiwiwiipak.
In 1997, Wipak installed a special streaming film line equivalent to a grade in Europe.

In 1996, at Minni apores, the company took the same approach by combining its relatively small medical film business with the acquisition of Perfecseal (a paper coating and conversion business)
This combination creates a larger medical packaging enterprise that has introduced to the market a lower-cost, highly layered medical molding film developed by Bemis\' Curwood food

Most of the medical packaging films of CastNorth america are blown films.
Due to its inherent orientation and greater tear strength, this process is the first choice for the formation of a film.
However, some blown film production lines originally designed for food packaging face challenges in the medical fieldfilm arena. High-output, water-
Quenching down
Extrusion bubbles may require different nylon formulations in medical treatment, as amorphous films often have more memory and shrinkage around packaged products.
This can be a disadvantage if it is a sharp or fragile medical device.
In Europe, streaming film is the first choice for extrusion medical film because it has better thickness control.
The streaming film also allows the control of morphology, so the film can become very amorphous with a softer feel than the blowing film. \"In the U. S.
It is still in the air that dominates the process, \"said a technical director for a large American enterprise. S.
A health care company, they made some medical films themselves.
Steve Post, actor film business manager at Davis, added --

\"Highly layered medical films are not made on traditional devices.
In order to make a flat film, wet treatment is usually required in the water tank and in the annealing coil.
\"To cope with the competition, the old medical film companies are naturally vulnerable to new heights.
Technology competition for food packaging manufacturers.
For traditional medical film makers, it is not easy to invest in new technologies, and they are less motivated to do so.
Once the medical packaging film is approved, the processor is not allowed to change or upgrade the extrusion line in any way without the customer\'s approval.
Therefore, many medical packaging films used for a long time
Running products are made with old equipment and technology. Food-
On the other hand, the packaging equipment is constantly upgraded. Coex food-
Packaging lines also typically use more advanced instruments to verify and control film thickness and barrier properties.
Perfecseal\'s new membrane plant in Wisconsin automatically monitors and controls calipers on coex cast and film blowing lines.
In contrast, most medical film manufacturers rely on gravity feeders and off-

It has already claimed compliance with ISO 13485 on its website, but has not yet been officially certified.
Rexam also responds to new competition by increasing production by means that it does not need to re-validate its processes.

\"We are trying to make movies better and faster.
\"A smaller film laminating machine deals with competition by installing coex coating operations.
In 1999, Rollprint invested $14 million in co-extrusion coating equipment with three extruder, and the fourth co-extrusion coating equipment for edge packaging, which is designed to be used in film,

The medical film processor says time suppliers and familiar materials, regardless of the cost.
\"The medical packaging business is obtained based on people you know,\" said the president of a extrusion equipment supplier . \".
\"This is a network.
Like a club.
\"The Food and Drug Administration can register for the use of specific medical devices, a process that may take several years or more.
However, in general, the FDA regulates medical devices, but the acceptable packaging options depend largely on the device manufacturer.
The FDA does not recognize films as independent products.
The equipment manufacturer verified the medical use of the film.
Verification regulations--
Basically frozen. -
Every aspect of production, including the exact resin grade and additives, extrusion parameters, and even the film made by a specific extruder in the factory.
Once the packaging is qualified, the production can remain unchanged for many years.
Nothing can be changed without informing the equipment manufacturer.
Changes will only be made if the purchaser sees sufficient cost advantages to justify the cost of re-certification.
Whether the device manufacturer informs the FDA of this change depends on the company practice of the device manufacturer and the importance of the device.
This relatively inflexible system means that a stable, long-term performance of the medical film processor must be ensured.
Long term supply of approved resin.
If a resin company stops producing one of these materials, the entire film must be re-identified with a new resin.
Since the migration of additives under various sterilization conditions is a big problem in resin selection, the new resin must undergo extensive re-validation tests.
Once approved, this is not common for medical care
Film processors adjust products to reduce costs.
\"Equipment manufacturers will not consider changing packaging unless it saves them hundreds of billions of dollars a year,\" said a medical packaging provider . \".
\"When the device they put in might cost $4500, they don\'t take a 45 cent package and try to lower it to 42 cents.
