Used blister sealer machines for sale 207

Blister machines belong to the Packaging category of used machines on Exapro. Blister packs (or blister machines) are used for packaging of pharmaceutical products, medicines, foods and small consumer goods. The main purpose of a blister machine is to form a cavity/pocket created with heat or pressure in order to protect goods from external factors. Blister packs prevent the influence of humidity and contamination on the products.

Packaging Process

There are 2 ways of packaging with blister machines. One is known as Thermoforming and another as Cold forming. What is the difference between the two?

• Thermoforming. As the name suggests, this process involves heating the packaging material up. Usually, plastic film is taken from the reel and forwarded through a pre-heating station. At the station, the temperature is kept on a high enough level to soften the plastic and make it pliable. Already warm and soft plastic arrives in a forming station where it is further formed into blister cavity under high pressure. After this stage, plastic is cooled down again so that it remains in a specific shape after the end of packaging process.
• Cold forming represents the opposite of thermoforming process. In case of cold forming, aluminium-based film is pressed into the desired shape with a stamp. So to form the cavity, pressure is applied to the laminate film, while aluminium allows to maintain the shape that has been formed. Blister packs made with cold forming provide almost perfect protection of good against oxygen or water which allows to extend the expiry date of the product. However, the speed production is lower as opposed to thermoforming.

Materials Used

What kind of materials are used for blister packaging? As mentioned above, it's mainly plastic or aluminium foil. Plastic or PVC (polyvinyl chloride) is most commonly used for thermoforming. The main advantage of this material is its low cost and the fact that it can be shaped easily. Cold form foil, on the other hand, is made of laminate containing 3 layers: PVC, aluminium, polyamide. So technically, it's not simply aluminium foil. The inside of the blister pack is made of PVC, the outside - of aluminium and polyamide.

Area of Use

Blister packs are used for packaging of medication, but also small consumer goods, such as toys or hardware. In pharmaceutical industry, blister machines are practically irreplaceable. Anyone who has been in the pharmacy shop at least once, has come in contact with pills or capsules packed in blister foil. Blister packs are so popular in the pharmaceutical world because unit-dose packaging assures packaging integrity of each pill allowing to extend medication shelf-life.

When it comes to consumer goods, electrical items, hardware or even kids toys can be packed with blister machines. A product will be safely positioned between cardboard and a plastic pocket formed with a blister machine. The biggest advantage of blister packaging consumer goods is the fact that the customer can clearly see the product through transparent plastic. At the same time, packaging is rigid enough to prevent any damage.

Strong Points

What are the biggest benefits of blister packaging? First of all, it is a cost effective way of packaging the product allowing clients to inspect it through transparent plastic at the same time. Blister pack provides a clear product display and plenty of advertising space at the back of the package at the same time.
