Nine Different Kinds of Wrapping Machines for Packaging Products?

The word ‘wrapping' when applied to packaging machines covers different styles and kinds of equipments. The main purpose of this write-up is to look at the extensive areas of packaging and to spot the types of machinery which are needed for enfolding. There are two kinds of machines available-one that covers up the product partially and the other that completely enclose it.

Let's first discuss about the equipments that wrap the products partially.

Banding machine

This equipment can cover a band of material around the product and seal it by glue or heat. The paper or film used should be thick or stiff. High density polyethylene is often used for the purpose.

Sleeve wrapping machinery

It makes use of one or two reels of film for enrobing a product with a loose film piece, which is shrunk tight through use of heat. Low density polypropylene is used as the material for packaging.

Stretch banding mechanism

This covers up a band of film firmly around an article or a group of merchandise. Polyethylene film that ranges from 30-60 micron is often used. The equipment is mainly utilized for distribution packs. They are used typically in pharmaceutical industry.

Spiral wrapping device

It firmly encloses the film around a product or a group of merchandise in series of turns. This kind of packaging is best suited for long products like ladders and articles that cannot pass through heat shrink tunnel.

Now I am going to discuss about the machineries that help in forming a complete wrap and here I would also like to mention that products can be completely packaged with sealing as well as without sealing.

Fold wrapping instrument uses paper or aluminum foil around the item without heat sealing for packaging. This kind of mechanism is generally used where the product has chances of getting damaged if heat is used.

Twist wrapping device can seal the end of the cover by getting the film twisted. The film used is often stiff and cellophane is basically used for the purpose.

Then there is the overwrapping tool that encloses the product with paper of sheet of film and uses a series of sealing and folding operations to form an enclosed pack.

Roll wrapping machines are also available in the market. They can cover up the cylindrical items in series of folding and heat sealing operations by making use of heat sealable film.

There is also another one known as foil and band wrapping instrument. Here the product first gets enfolded in an aluminum foil and then in band of paper. It is mainly used to pack chocolate bars and confectionery items.

The Housingless stand mill, engineered by is extensively used in different heavy industrial units

In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform.The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is known as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is known as cold rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes.Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (I-beams, angle stock, channel stock, and so on), bar stock, and rails. Most steel mills have rolling mill divisions that convert the semi-finished casting products into finished products.
