Blister - what is it? Advantages and production of blister packaging

Blister - what is this? The word "blister" appeared in English around the 14th century, it is believed that it originated from the old French blostre , which means "typhoid nodule". In English, the term blister means a skin inflammation like a blister. They can be filled with blood or pus, depending on how and where they are formed. The bubble is formed from the epidermis - the upper layer of the skin. Its purpose is to protect and soften the lower layers, which helps to stop further damage and promotes early healing. What does blister mean in Russian? What do modern packaging and watery corns have in common?

Blister - what is this?

In English, it is a blister that can appear on the skin for various reasons. Corns are most often formed due to excessive friction, for example when wearing uncomfortable shoes or when playing a musical instrument. Most often, bubbles filled with liquid appear on the areas of the skin with a thick stratum corneum (for example, the palms of the hands and the soles of the feet). In a neglected state, this can become a serious medical problem and lead to infection and ulceration. As a rule, this happens rarely. Rescue can be a regular adhesive plaster. Friction of skin areas is not the only cause of corns, they can occur as a result of burns or frostbite. In both cases, the bubble is a protective mechanism.

When exposed to the skin of certain chemically active substances, contact dermatitis may occur. This may be poor-quality cosmetics, detergents, solvents, nickel sulfate (used in electroplating), insect bites, warfare agents, including mustard gas, etc. Bladder medical conditions include chicken pox, cold ulcer due to herpes simplex, eczema, herpetiform dermatitis , Exposure to radiation, bullous epidermolysis and many other diseases.

Blister - what is that? This is a modern type of packaging, which got its name due to the external similarity to the inflated corn on the skin. This form of packaging provides good visibility of the product, thereby allowing customers to view the product before purchase.

Blister as a kind of packing

Blister is widely used as a portion pack for pharmaceutical tablets, capsules or lozenges. It can provide long shelf life, which is very important when storing medicines. It is created from rolls of a flat sheet of special aluminum foil or cardboard and plastic capsules on special equipment. Goods such as toys, equipment and electrical appliances can be packed in a plastic vacuum housing with a cardboard base. Blister - what is it in the packaging industry? What is it used for? This is a kind of plastic packaging that is used in the pharmaceutical and light industries. This modern method is used to pack medicines, capsules and other consumer goods.

Using

Light industry mainly uses blister packing machines. Packing type blister is most often used for such general goods as electronic and electrical products, toys, pens and many others. This method allows the consumer or potential buyer to examine the product in detail without unpacking. This variety
Polyethylene packaging is one of the popular types of plastic packaging that can increase the attractiveness of goods and improve its presentation.

Production of blister packaging

Various materials can be used in the manufacture, including cardboard, plastic, foil or any other laminated material. They are attached to the blister in the process of heat sealing with glue. The bonding force is strong enough to support the weight of the product when it is hung, for example, on a commodity stand, and weak enough that the bag can be easily opened. Blister production is carried out through highly automated equipment. Blisters are available in two forms: sealing and sliding. Sealed type packaging is made using high-quality PVC and rigid film. Thermoforming is the manufacturing process, during which the sheet of plastic is heated to a certain temperature, after which special niches are formed, where the product will subsequently be located. The sheet substrate is heated in the furnace to a high temperature to stretch it to a certain size, and then cooled. Making complex vacuum packaging is a continuous high-tech and high-speed process. And depending on the machine and the size of the molds and parts, you can produce many thousands of finished products per hour.

Advantages of blisters

Blister packaging is manufactured using high quality raw materials, it is available in various shapes and sizes. This is a modern and high-quality shell, which guarantees the unharmed product. The biggest problem that any manufacturer of a product faces is the safety of the product during transportation and delivery. Blister packaging is the best solution. This preformed plastic packaging is used for packaging products, primarily to protect them from damage.
So, the main component of the blister package is a cavity or pocket made of a molded web of heat-resistant plastic and a substrate made of cardboard, aluminum foil or plastic. Blisters protect the product from external factors, such as moisture and pollution, for a long period of time. Opaque packaging protects light-sensitive products from UV rays.
