The packaging industry has some of the most complex machinery which consist of complicated algorithms it seems as though one has to be a rocket scientist to build such machinery.  These machines have to be extremely accurate when filling bottles with a half inch opening or making sure not to over fill a bag and keeping it from bursting.

Near the last stage of this tedious process it is normal to find products bundled together in plastic or boxes.  This gets the product prepped and ready to be shipped off to local retailers or buyers around the world.  Packaging companies prefer shipping their products in plastic rather than boxes because they take up less space and weigh less.

There are many types of plastic or bag sealers that are used for different purposes.  To understand which type of bag sealer is best for a specific function listed below are 7 different categories these seals fall into.

Industrial Bag Sealers.  This is used for applications that require more sealing power and/or higher speeds than normal.  Found in many large packaging companies these bag sealers are perfect when mass producing bagged products.  For example, Kraft’s Macaroni and Cheese that we find in every grocery store.

Validatable Bag Sealers.  These machines are perfect for packaging medical or pharmaceutical products.  These machines make it simple to change out parts of the machine to accommodate for different size bags that are continually interchanged.

Semi-Automatic Bag Sealers.  If you want to have multiple people loading your sealer or if you need to automatically load your sealer, these sealers are perfect for the job.

Portable Sealers.  If you need a portable sealer, or a low production sealer that may be used occasionally the portable bag sealers are perfect.  These machines are small weighing on average about 15 lbs.

Hot Air Sealers.  If the product you are packaging is extremely dusty and air borne and is pillow shaped a hot air sealer is the right machine. For example bags filled with seed or dirt is commonly sealed in this manner.  The bag is sealed in an upright position where the top of the bag is guided through the hot air sealer.

Vacuum Sealers.  This machine is used to create an air tight package which is best for preserving products.  These type of bag sealers have been made available for household usage to keep meats and perishables fresh longer.
Standard Bag Sealers. These types of bag sealers are for sealing pre-made, open mouth heat sealable bags.  Once the product is dispensed into the plastic bag the open end of the bag is pressed with a heated clamp that melts the plastic together sealing the contents inside.  These standard sealers may seal up to 500 bags per minute depending on the size.

Product differentiation is more important in this industry then cost leadership so it is important to understand the purpose of these machines.  Some may overlap into other categories allowing you to get more for your money so understand the job required of these machines so you choose what best fits your needs.
