Bag sealers help to make bag sealing faster. Bag sealers are classified according to the technology used to make them. Modern bag sealers are sophisticated gadgets that are much different from the manual bag sealers used several decades back. The material used to make bags has also undergone a sea change. Likewise we have a wide product range of bag sealers to choose from. Selection of a Bag sealers must be done only after a thorough analysis of the entire present requirements and the future needs that may arise.

Decades back, only cloth bags were in wide use around the world. Then the use of bags made from jute and other eco-friendly products became widespread. Fast technological progress replaced manual bag sealing and now small bag sealing machines are available for sealing cloth bags, jute and even gunny bags. The use of these machines made bag sealing quicker and more efficient. While manual sealing is time consuming, error prone and labour intensive, bag-sealing machines gave better output with less labour.

Types of bag sealers

Bag sealers of different type and make are now available to seal bags made from a wide range of materials. Industries can choose manual, semi-automatic or even automatic Bag sealers according to the type of bag materials used for packing the various products. There are bag-sealing machines that even seal the bags and do the labelling simultaneously.

A wide range of bag sealers is available for sealing plastic bags. Today no modern food processing industry can afford to do away with the bag sealer. Processed foods need to be preserved for long periods and transported to huge distances across the globe. Food preservation through refrigeration and freezing is costly. A processed food item may reach the hands of the customer only after several months or even years. Such processed foods need to be preserved from air and water contamination and also from decaying bacteria and fungi. Thus carbon dioxide gas was filled in the plastic bags along with the processed food products to protect them from decaying bacteria and fungi and also to improve their shelf life. For packing fried food items for a long time and to keep them crisp nitrogen gas was used. Plastic bags filled with carbon dioxide or nitrogen gas needed airtight packing, so that the processed foods will not be contaminated. Not only that, the sealing must be strong and durable. The technology employed has advanced to such an extent that today even vacuum packing and sealing is possible.

Small and medium industries needed small manually operated bag sealers. But the needs of heavy industries are different. Large factories producing sugar, animal feeds, plant fertilizers and even cement weigh and pack the produce in an assembly line and the Bag sealers simultaneously seals and labels them. Such huge industries use big bag sealers. They come in different models and the industry mostly prefers the automated ones. Simultaneous sealing and labelling is a recent innovation. Such bag sealers were earlier electronically controlled. But now even computerized Bag sealers are available. This ensured better output from the bag sealers and the labelling and numbering became error free.

Product selection

Faster bag sealing is possible through double element sealers. They have heating elements on both the upper and lower jaws and it is the preferred model for sealing thick polyethylene and even polypropylene bags. Bag sealers with cutters will make bag sealing faster and easier. A buyer needs to make a list of the various types of bags he is using at present and the number of bags that must be sealed in an hour. Then he should zero in on a particular product. If the number of bags to be sealed are less, manual hand operated bag sealers will be enough but if more work needs to be done in less time, then the use of semi-automatic or even automatic Bag sealers will become inevitable.
