Blister - what is it? The word "blister" appeared in English around the 14th century, it is believed that it came from the Old French blostre , which means "typhoid nodule." Translated from English, the term blister means a skin inflammation such as 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 stop further damage and promotes early healing. What does blister mean in Russian? What do the modern packaging and watery corn have in common?
Blister - what is it?
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 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. This usually happens rarely.
A salvage can be a regular band-aid. 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 can be low-quality cosmetics, detergents, solvents, nickel sulfate (used in electroplating), insect bites, chemical warfare agents, including mustard gas, etc. The medical conditions for blisters include chickenpox, cold sores as a result of herpes simplex, eczema, and herpetiform dermatitis , exposure to radiation, epidermolysis bullosa and many other diseases.
Blister - what else is it? This is a modern type of packaging, which got its name due to the outward resemblance to puffed callus on the skin. This form of packaging provides good visibility of the product, thereby allowing customers to consider the product before purchase.
Blister as a type of packaging
Blister is widely used as unit dose packaging for pharmaceutical tablets, capsules or lozenges. It can provide long shelf life, which is very important when storing drugs. It is created from rolls of a flat sheet of special aluminum foil or cardboard and plastic capsules on special equipment.
Products such as toys, equipment and electrical appliances can be packaged in a plastic vacuum case with a cardboard base. Blister - what is it in the packaging industry? What is it used for? This is a type of plastic packaging used in the pharmaceutical and light industries. This modern method is used for packaging medicines, capsules and other
consumer goods.
Using
Light industry mainly uses blister packaging machines. Blister packs are most often used for general consumer goods such as electronic and electrical products, toys, pens, and many others. This method allows the consumer or potential buyer to examine in detail the goods without unpacking. This variety
plastic packaging is one of the most popular types of plastic packaging that can increase the attractiveness of a product and improve its presentation.
Blister packaging
In the manufacture of various materials can be used, including cardboard, plastic, foil or any other laminated material. They are mounted on a blister during heat sealing with glue. The bonding strength is strong enough to support the weight of the product when hanging it, for example, on a commodity stand, and weak enough so that the bag can be easily opened. The production of blisters is carried out through highly automated equipment. Blisters come in two forms: sealing and slip.
Hermetic packaging is made using high quality PVC and rigid film. Thermoforming is a manufacturing process during which a plastic sheet is heated to a certain temperature, after which special niches are formed where the product will subsequently be located. The sheet base is heated in a furnace to a high temperature to stretch it to a certain size, and then cooled. The manufacture of 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.
Blister Benefits
Blister packs are made using high quality raw materials and are available in various shapes and sizes. This is a modern and high-quality shell that guarantees the integrity of the product. The biggest problem that any manufacturer of goods faces is the safety of the product during transportation and delivery. Blister packaging is its best solution. This pre-formed plastic packaging is used to pack products, primarily to protect them from damage.
So, the main component of a blister pack is a cavity or pocket made of a molded web of heat-resistant plastic and a substrate of cardboard, aluminum foil or plastic. Blisters protect the product from external factors, such as humidity and pollution, for a long period of time. Opaque packaging protects photosensitive products from UV rays.
