HEAT SEAL Meaning and
Definition
-
Heat seal refers to a method or process of sealing or joining two surfaces together using heat application. It involves melting or activating a thermoplastic material, which is then allowed to cool and solidify, creating a strong and durable bond between the surfaces. This technique is commonly used in packaging industries to ensure the security and integrity of various products.
In heat sealing, the two surfaces to be joined are typically made of plastic or other thermoplastic materials. These materials have low melting points, enabling them to be easily manipulated by heat. The heat is usually applied through heated plates or rollers, which press the surfaces together, creating a molten layer that fuses them upon cooling.
Heat sealing is widely utilized in the manufacturing and packaging of products such as food, pharmaceuticals, electronics, and textiles. It is employed to create a seal that offers protection against moisture, contaminants, tampering, and other external factors that may compromise the quality or safety of the products.
Different heat sealing methods exist, including direct heat seal, impulse heat seal, and hot bar seal. Each method has its own advantages and applications, depending on the specific requirements of the product being sealed. Heat sealing is preferred due to its efficiency, cost-effectiveness, and the ability to create airtight and watertight seals, which contribute to product preservation and safety.

Etymology of HEAT SEAL
The word "heat seal" is composed of two parts: "heat" and "seal".
The word "heat" is derived from the Old English word "hǣtu" or "hǣt", which in turn stems from the Proto-Germanic word "haitīz". This Proto-Germanic root word is related to the Old High German word "heiz", meaning "hot". Over time, "heat" came to represent the form of energy associated with the sensation of warmth.
The word "seal" has multiple origins. One origin is from the Old English word "seolh", which referred to the marine mammal. Another origin is from the Old English word "seolfe", meaning "mark" or "sign". Both origins share the idea of creating a distinctive mark or impression.
