Laboratory Heat Sealer

Heat Sealer is a consistent tool used to perform sealing on flexible packaging products and other thermoplastic materials using pressure and heat by maintaining high temperatures. Effective Lab Heat Sealer is manufactured under various Test Standards such as ASTM F 2029.

A Laboratory Heat Sealer is an equipment which is used for sealing products, packings, and thermoplastic materials samples. This machine seals the product by using heat. 

This can occur with materials having multiple layers, one of which is thermoplastic, or with homogeneous thermoplastic monolayers. Heat sealing machines can be used to fuse dissimilar materials, or to fuse two materials that are similar.

There is a direct contact method of heat sealing in which a constant heating bar is used to heat the specific material.
