Blister Packaging
We offer all kinds of blister packaging ,our main is custom blister packaging to meet the needs of different customer requirements.
We meet different customer's needs and incorporate them into the design of each blister package. Our packaging design team can develop a fully customized blister packaging that meets your exact specifications.We make a variety of shape plastic clamshell packaging and trays which will show your product in the best way!
Thermoforming Blister Tray packaging and other therformed blister tray offer high durability over carton box or corrugated paper ,blister insert tray are esay to manufacturer and are cost-effective,making this type of packaging highly popular and budget friendly.Thermoforming blister tray packaging and other blister tray is much faster than injection molding with a much lower tooling cost as well.
Blister clamshell packaging can be divided into double blister packaging and tri-fold clamshell .
Blister packaging is a unique packaging product. The appearance of the product is protruding and has a three-dimensional effect, and what is produced is the contour of the packaged article.
Blister packaging is mainly used in toys, stationery, electronics and other products. The main advantage of using blister clamshell packaging is to reflect the uniqueness of the product.

The working principle of the globe valve and selection principle introduction
Cut-off valve is also called the cut-off, is the most widely used type of valve, the reason why it is popular because of the friction between the sealing surface during opening and closing process is small, more durable, open height, easy to manufacture, easy maintenance , Not only for low pressure, but also for high pressure. Closing valve closing principle is to rely on valve stem pressure, so that valve disc sealing surface and seat sealing surface close fit, to prevent the circulation of media. Globe only one-way media flow, the installation of a directional. Shut-off valve structure is greater than the gate valve length, while fluid resistance, long-term operation, the sealing reliability is not strong. Globe valves fall into three categories: Straight-through globe valves, right angle globe valves, and straight-flow diagonal globe valves. The most obvious advantage is that during the opening and closing process, the valve plate is wearable because of the lower friction between the sealing surfaces of the valve body and the gate valve. The opening height is only 1/4 of the diameter of the valve seat passage, so it is much smaller than the valve. Usually there is only one sealing surface on the valve body and the valve disc, so manufacturing technology is relatively good and easy to maintain. Nominal pressure or pressure level of globe valve: PN1.0-16.0MPa, ANSI CLASS150-900, JIS 10-20K, Nominal diameter or diameter: DN10 ~ 500, NPS 1/2 ~ 36 ", Globe valve connection: Flange , Butt Weld, Threaded, etc. Applicable Temperature: -196 ℃ ~ 700 ℃, Stop Valve Actuation: Manual, Bevel Gear, Pneumatic, Electric, Hydraulic, Gas-Liquid, Electrohydraulic, Body Material: WCB, ZG1Cr18Ni9Ti , ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti. Choose different material for the shut-off valve, can apply to water, steam, oil, nitric acid, acetic acid, oxidative medium , Urea and other media.Close-off valve is the closure of the valve (valve) moves along the centerline of the valve.According to the valve disc in this form of movement, valve seat opening change is proportional to the valve disc stroke. Because of this valve stem opening or closing stroke is relatively short, but also has a very reliable cut-off function, but also because the valve seat opening changes in proportion with the valve disc stroke is very suitable for the flow of regulation.Therefore, This type of valve is very suitable for making Cut off or adjust and use the throttle valve selection principle is: 1. High temperature, high pressure medium pipe or device should use the globe valve, such as thermal power plants, nuclear power plants, petrochemical systems, high temperature, high pressure pipeline. Pipeline convection resistance on the lax requirements of the pipeline. That is, the pressure loss is not considered little place. 3. Small valve optional needle valve, valve, sampling valve, pressure gauge valve, etc .. 4. Flow adjustment or pressure regulation, But the regulatory accuracy is not demanding, and the pipeline diameter is relatively small, such as the nominal pass through the pipeline ≤50mm, should be used. 5. Synthetic industrial production of small fertilizers and large chemical fertilizer should be used Nominal pressure PN160 Nominal pressure 16MPa or PN320 Nominal pressure 32MPa high-pressure angle type globe valve or high-pressure angle type stop valve 6. Alumina Bayer process in the production of desiliconization workshop, easy coking pipe, easy to use separate valve body, seat removable, hard Quality alloy sealing the DC cut-off valve or DC cut-off valve 7. Urban construction of water supply and heating works, the nominal pass through the smaller pipe, the optional cut Valves, balancing valves or plunger, such as less than 150mm nominal pass through the pipeline.
