What is a blister machine?
Blutric machine is a piece of equipment capable of creating pre -defined packages that can be used to seal objects such as food, medicine and various consumer products. Two primary methods can be used to achieve this that the blister machine can use: thermal and cold formation. Some machines are able to use only one of these methods, while others are multi -purpose devices. Most blister machines use polyvinyl chloride (PVC) to create a packaging, although other materials can be used. Blisters are also able to create slightly different types of packaging, such as pharmaceutical blister packages with released backs and cases used to hold consumer goods.
There are two main ways to form a blister machine can form the material leaves in the package. Thermoforming is a technique that includes PVC heating leaves before inserting into the blister. This is usually achieved by passing the leaves between the upper and lower heating plates. When the sheet enters the thermoformming blister machine, it is softand flat and may be forced to take over the shape of the mold by means of pressure. In some cases, in addition to the application of pressure, a mechanical stamp will be used, especially if the shape of the mold is difficult or complex.
The type of packaging created by thermo -forming can be used in many different applications. Some blister machines that use this technique are designed to create pharmaceutical blister packages. This type of packaging usually contains separate blisters for each pill and has a passage foil or paper on the back.
Other blister machines are designed to create a type of packaging, often used to hold consumer goods. These machines will usually push each side of the clamshell individually, and then they can be sealed. Thermoformming blister machine can also create one -up -to -date blister packages, which are then connected to cardboard cards.
cold formation is a technique,that does not include any heat application. Unlike the thermal formation method, which uses clear PVC, this technique uses thin leaves of laminate film that contain aluminum. In order to create a package from these sheets, the blister machine will usually use a stamp to force it into a mold. The aluminum -based film will tend to stretch and keep the shape after removing the stamp. This type of blister package is usually used for the pharmacy content, because the aluminum -based film tends to prevent moisture from entering the packaging.
