High barrier films are widely used in the packaging of food, medicine, daily necessities, especially in the medical field, high barrier films are required for infusion bags, medicine bags, blood collection bags, and medical compound packaging bags . Now let's take a look at the application examples of high barrier films in medical treatment.
Benton, located in Bentton , Ontario, Canada, has sold two AquaFrost under-blow water-cooled production lines to European blown film flexible packaging plants . This was announced by the company's president not long ago. After 9 months of extensive customer trials, the company received a 9- tier and a 10- tier order from European customers . By using water as a cooling medium, AquaFrost can improve output, and the produced composite film has the characteristics of high transparency, balanced stretching and deep drawing thermoforming. Brampton company in the K2001 had introduced the related principle AquaFrost production line. The president of the company also said that since then, they have been trying to improve and perfect their equipment and technology through the trial of the 5- layer AquaFrost production line of their blown film technology center and the customer's 9- layer beta system. Benefits and potential. Through on-site testing, they can also prove to customers that their technology and products can benefit customers greatly.
Customers are concerned that AquaFrost can produce films with good transparency and very softness, and consider using this high-volume production line to replace the cast film production line. The president of Brampton also expects that sales of the AquaFrost production line will be better soon . Because this technology is a major contribution to the blown film market. When competitors see this film, they will realize that they must use AquaFrost to produce high-transparency, high-yield films. In addition to the two advantages of high transparency and high output, AquaFrost also has more economical features. Compared with the casting line, AquaFrost produces less waste when both trimming and width conversion are performed . Bill Wybenga , technical director of Brampton, said, "The AquaFrost system uses all the components that the customer expects from Brampton Engineering. The core of the system is our SCD (streamline co-extrusion die).
The AquaFrost production line, die head and extruder are located at the top of the tower, and the film bubble is blown down through an AquaRing (water tank), which is conducive to rapid cooling of the molten polymer to improve yield and film transparency. The bubble passes through a reversed herringbone splint and rotary traction device. In addition, the system uses Benton's I-Flex movable lip to ensure accurate thickness control.
As can be seen from the above example, the prospect of high-barrier film in the medical packaging market is very broad. In the next few years, high-barrier film will give full play to its advantages.
Gas pressure reducing valve is a valve in the body of the opening of the opening and closing of regulating the flow of medium, the medium pressure is reduced, at the same time with the aid of the role of the valve after pressure adjust the opening of open-close part, keep the valve after pressure within a certain range, and the valve body or valve after the injection of cooling water, reduce the temperature of medium, the valve is called desuperheating valve to relieve stress.The characteristics of gas pressure reducing valve are that in the case of constant changes in inlet pressure, keep the outlet listening pressure and temperature value within a certain range, and this type of valve should be installed horizontally in the pipeline generally.
