Optimize your flexible packaging performance with Presto heat sealer

Gaurav Malhotra

When it comes to packaging products, determining the quality of sealing is one of the important factors to consider that will protect the contents from tampering. From improving product shelf life to protecting the integrity of your product, the seal of flexible packaging films will play an important role in determining the quality of the product. Thus, we at Presto have designed high-quality lab testing instruments known as laboratory heat sealers. This lab testing instrument is used to perform sealing on flexible packaging films and other thermoplastic materials using pressure and heat by maintaining high temperatures.

In this article, we are going to provide you with information about the Presto heat sealer machine and how this quality testing instrument is useful in measuring the heat seal performance of composite films, plastic films, and many more.

All about Presto laboratory heat sealer

Ensuring proper sealing of packing materials is key to making a product functional and preserving its barrier characteristics. Therefore, if you want to extend the shelf life of your product, make sure it's securely sealed. Thus, we at Presto have designed a high-quality laboratory testing instrument that is used to perform sealing on flexible packaging of products and other thermoplastic materials using pressure and heat by maintaining high temperatures.

This laboratory heat sealer is widely used lab testing equipment in the packaging industry and can measure the heat seal performance of composite films, plastic films such as PP, PE, and other packaging films used in the packaging of different food products.

This heat-sealing testing equipment is mainly used in the packaging industries and industrial laboratories to test the heat-sealing ability of the materials. You can ensure perfect packaging with the Presto heat-sealing testing instrument. Now, let us discuss briefly the features of this quality testing equipment.
