Packaging Machinery - News, Technology and Reviews

The plastic substances have derived their name from some properties namely plasticity and malleable nature. The plastic is a polymeric substance. Plastic is the substance that literally is involved in every aspect of our lives. We use plastic as in various different modes, be it carries bags, Tiffin boxes, watches, frames, and various other equipments.

It thus provides various applications as such. The area of discussion is limited to packaging part of the plastics, which in itself is a huge and profitable industry. Along with products, the packaging part comes as a very important issue.

In order to safeguard valuable products from climatic changes, deterioration, malfunction or destruction; packaging comes as very necessary part and there are various processes and materials employed for the very same purpose. Many equipments and machines are constructed for various styles of packaging.

Materials used for Plastic Packaging

There are huge varieties of materials used for plastic packing and packaging. They are molded by related equipments and machines. Some of them widely in use are polypropylene straps, rolls, sachets, stand pouches, gusset pouches, zipper pouches, PVC tapes and films, HDPE materials, corrugated pallets, bubble wraps, refuse black plastic sack materials, shrink wrap plastic for tubing purposes etc.

Machineries and Technologies Employed

One of the common methods for such purpose is called as plastic extruding. There is this unifill system of packing which employs form-fill-seal methodology. It is employed for packing fluid and semi fluid substances. Vertical thermoforming method is applicable for this style and in which thin plastic shits are made to be preheated and monodose strips are brought out. Then the top is sealed continuously to get a series of packaged materials. There are various form-fill-seal machines for this purpose.

There is another process named as aseptic filling in which non-carbonated liquids, dairy products, beverages etc. are packaged in a very swift speed and in an efficient manner. The machines are known as linear aseptic machines generally.

Some other machines worth mentioning the names are blister sealing and cutting machine, high speed pressure forming machine, Form vacuum machine, moulds, dies and cutting machines. In general, the methods primarily implemented are axis routing, extruding, silk screening, hot stamping, plug and ring etc.

Major companies in the Industry

There are huge companies in big, medium and small scale dealing with plastic packaging machineries. Some of them are Tetra Pak, Jieh Hong Machinery Co., Tong Shin Pack  etc.
