Heat sealing (thermal sealing) involves the process of joining two or more thermoplastic films or sheets by heating the areas in contact with each other at a temperature at which fusion occurs, usually assisted by pressure. The heat is supplied by a rotating electrode or dies that are maintained at a constant temperature
A heat-sealed card-to-card blister pack comprises a combination of a folded or separate front and back blister and a transparent blister, bonded together under heat and pressure. Blister and carton together form an aesthetically pleasing product presentation.
Heat sealing of plastic with plastic is achieved by bonding the two parts together under the influence of heat (radiant or impulse) and pressure. For the successful sealing of plastics, it is critical to use the right material for the manufacturing of the blister. Not all plastics are suitable for sealing, and depending on the design of the blister, tooling is always a key factor in ensuring that the packaging process runs smoothly.
Card-to-plastic sealing—this blister sealing method combines a piece of cardboard and a blister, making it a very economical production option. The board is coated with a layer of proven, environmentally friendly, water-based sealant. After the product has been added, the blister can be directly adhered to one side of the carton using heat and pressure. Typically, depending on the market in which they are used, the blister packs are made of materials such as PET or PVC.
Heat sealing technology offers many advantages. Most importantly, it is a fast and efficient process that allows for the combination of many types of materials in a short period of time. This allows more efficient production, resulting in lower costs. Furthermore, permanent heat sealing is very precise, allowing the creation of high-quality products. It is in especially important for packaging production, where precision and aesthetics are crucial.
Heat sealing represents a technology widely used in many industries. It is irreplaceable in the packaging industry, where it is used to produce products such as blister packs.
Heat sealing refers to a technology that allows multiple materials to be joined using heat. It may be applied to join thermoplastic foils, plastics and other materials with the use of heat-activated adhesive. This makes it a multi-purpose technology that can be used in a wide variety of production methods.. Heat sealing always guarantees high quality and precision.
Choosing the right fixed heat sealing machines is essential for production efficiency and quality. Above all, it is essential to pay attention to the technical parameters of the machine, such as power, operating temperature and welding time. It is also important for the machine to be adapted to the type of materials to be joined. By choosing machines from reputable manufacturers, you can count on high quality and reliability. Finally, technical support and after-sales service are also of paramount importance. By having access to technical support, you can be assured that if there are any problems with the smooth operation of the machine, you will be able to receive quick and professional assistance in solving them.
