When products are manufactured and distributed, packaging is usually the last step but a critical barrier between an untouched product and the environment. Packaging must be more than a holding mechanism, it must preserve freshness, maintain sterility, and allow for a tamperproof seal. The success of such quality packaging is reliant on an unsung machine, the sealing machine; more precisely, heat sealing equipment is fundamental to securing the integrity of innumerable packages across sectors worldwide.
A heat sealer is an electromechanical device for the bonding of two thermoplastic materials using controlled heat and pressure, and it is the heat sealing process that is responsible for providing a secure and hermetically tight seal essential for many products.
This is important, as damage from poor packaging or sealing - which can be easily caused by the heat sealer malfunctioning - would be an immediate loss of opportunity with all of the other aspects of quality that had to be built and paid through the cost of costing recalls, waste, and possible loss of reputation.
The high-precision models, often called a laboratory heat sealer, are designed to provide highly controlled and repeatable parameters of temperature, pressure, and dwell time for seals in R&D and quality control applications. These features of the precise, consistent, and advanced controls are reflected in this kind of laboratory heat sealer price.
A perfect seal isn't a matter of guessing. Instead, it is a science that takes into account three important parameters: temperature, pressure, and dwell time. As with all packaging materials, the right combination will vary, and small differences will usually render the resulting seal either too weak and leaking or too hot and can damage the film, leading to brittle seals. This is where the lab Heat Sealer comes in.
A Heat Seal tester is a specialized quality control instrument that measures the optimum sealing parameters for a given material and checks the performance of a production sealing machine on a routine basis.
Creation of Test Seals: The tester makes a set of test seals on samples from the packaging material, varying systematically the temperature, pressure, and/or time.
Peel force testing of seal strength can be done on the sealed samples using a separate tensile tester, which measures the actual force required to pull the seal apart. Results, typically expressed in Newtons per millimetre (N/mm), enable packaging professionals to pinpoint where the so-called 'sweet spot'-the combination of settings yielding the strongest, most reliable seal-can be found. For instance, a high-end, dedicated testing unit such as the Heat Sealer Prima is usually employed in quality assurance departments to carry out these critical tests. The precision afforded by the Heat Sealer Prima enables manufacturers to confidently set their production heat sealing equipment to the exact specification needed to achieve maximum quality and minimum product failure. As surely as these tests have been completed, you will know that the package is assured to perform its intended function through the supply chain. Selecting the Right Solution Whether the needs are a high-speed industrial line, or compact laboratory heat sealing, selecting the right heat sealing equipment is an investment in the integrity of your product and the reputation of your brand.
