Food film production industry new development direction - food packaging

Food film producer is higher in manufacturing technology to reduce the medical cost of packaging, to become a medical film producers market competition.

At present. The whole time medical packaging film market food increase product longpacket rate shipped to 2% ~ 4% with thin film,. Large in each annual and the United States, if you want to cancel a medical packaging film supplier sales qualification. The U. S. Food and drug administration need to Xiamen FDA) on the re certification of products.Therefore, medical packaging films in the United States is also seen as a stable businessproject, general manager of banana as a healthcare packaging products company says,once entered the medical packaging film market, it is unlikely to lose business, unless there is a big mistake.

In the past one and a half year time, several large supply isolating packaging of foodproducers in the production of CO extruded films now has to do with the medical packing material qualification at present. Most of the production of food for the film company hasmedical film business a little. Over the years the company is committed to their direct low cost film products drive the system I with multilayer structure thin film technology is applied to medical film Market: now. They have become the medical market with high added value of major competitors in the field of professional.

Multilayer film for food packaging manufacturers hope to enter the medical packagingmarket

Usually, the medical packaging requirements and the requirements of the food packagingis entirely different. Soft food packaging, in order to good preservation of processed meat and cheese, must have oxygen isolation features tight. For medical packaging film extrusion, must be able to meet the isolation microbe, not easy to be punctured and can withstand sterilization and other requirements.

Food with a film production company brings is the multilayer structure of the technology.Co extrusion technology can reduce the cost in several aspects. By CO extrusion technology. Can use more resin material to replace some expensive raw materials. In addition. Sometimes also can reduce the production steps through the cancellation ofcoated or laminated operation. Highly layered medical component films can be used PE - Nylon - PE - Nylon - PE such a structure or in the same structure. Fortunately, replace the nylon with PP. This structure can reach 2 to 16 mils (1/1000 inch) thick, but is usually 6 to 9 mils thick. In these films, nylon is used to increase the breakdown strength. In the medical packaging material is poured in, do not need to use the EVOH, because of the need not to isolate oxygen.

Manufacturing of thin film has sterilization ability

Usually the liver two common method of sterilization is the use of epoxy ethane gas and radiation. In the medical packaging patent product, pedicle tank g spunbondedpolypropylene non-woven fabric fiber air ministry often use medical paper or DuPont Co,this kind of breathable material allows the epoxy ethane gas import. In addition, the high temperature and high pressure steam. Sterilization, hydrogen peroxide or plasma are often used for disinfection of hospital internal, but these methods can not be applied tomost of the medical packaging.

So far, used for the bottom heat device packaging molding film is usually 3 layer co extruded films, namely the crosslinked polymer EVA ion EVA this three layer, orsandwiched EVNPE blend layer ion crosslinked polymer layer. Ionic crosslinking polymertenacity and bright, but the price is more expensive. If: the need for heavier composition of specifications or packaging film, can be 3 layer film folding will by EVA / ionomer blownup to form 6 layers of thin films.

In the sealing portion of the medical device packaging, usually by extrusion coating and laminating method through the production of paper, plastic and metal sheet compositematerial, this kind of sealing the opening of the fabric with special effects. It can, can guarantee is quickly opened in an ambulance or emergency room, remove the syringe.

The three layer structure of packaging sterilization bag cleaning bag is usually adopts EVA and ionic crosslinking polymer composition, ion cross-linked polymer that layered structure with characteristic of linear tear. If the disinfection gas use, most of the bags will have a high density polyethylene synthetic paper or paper made breathing holes or the top stripe. With top striped bag do not need to go through the linear tear can be opened,linear low density polyethylene or polyolefin film multilayer so you can use single.
