Packaging is the science, art and technology of enclosing or protecting products for distribution
, storage, sale, and use. And what makes packaging unique is the quality of product used in packaging the product. And one of the crucial products used in packaging is a Heat Seal bag.
Heat seal bags are usually used made of fine grade PVC that assures superlative quality. They are designed to provide complete safety to the products packed in them. Heat Seal Plastic Bags are available in numerous sizes to suit different requirements of clients. Not an end consumer product, Heat Seal Bags is brought by companies dealing with the business of packaging products.
There are several manufacturers and distributors of Heat Seal Bags spread across various parts of the world. Heat seal bags are often supplied to various industries and stores where they are used for packing of various items.

How is a Heat Seal Bag manufactured?
Heat seal bags are manufactured using a heat sealer machine. It seal products and thermoplastic materials using heat. Heat sealing can join two similar materials together or can join dissimilar, one of which has a thermoplastic layer.
Types of heat sealing
Hot bar sealers- They use one or two heated bars which contact the material to heat the interface and form a bond.
Continuous heat sealers- utilize moving belts over heating elements.
Impulse heat sealers- When the materials are placed in the heat sealer, they are held in place by pressure. An electric current heats the heating element for a specified time to create the required temperature. The Jaws hold the material in place after the heat is stopped, sometimes with cooling water: this allows the material to fuse before stress can be applied.
Hot melt adhesive can be applied in strips or beads at the point of joining. It can also be applied to one of the surfaces during an earlier manufacturing step and reactivated for bonding.
