A high percentage of heat sealed products require proper air or fluid containment measures in their fabrication. The factors that dictate which process will work best are: the intended function, the size and/or configuration, and to a lesser degree, the material(s) used. Most products begin as a concept that will satisfy a need or serve as a solution to a problem. Once the heat sealing process is determined to ensure the functionality of a containment product, our expertise in process and material selection will help you to achieve successful fabrication.
Radio frequency welding and heat sealing are the strongest and most secure methods of containing the contents inside a flexible product. Radio frequency sealing provides a high integrity bond to counter the stresses inherent in products that are designed to contain and control the contents. RF welding is a bonding process that creates air- or liquid-tight seams for containment products.
All directly related factors are taken into account when seam construction and configuration are determined. In some products, the tensile strength of the seam may be as important as—or even more important than—air or fluid containment. The focus for proper containment is to determine the best functionality requirement of the product.
SealWerks provides contract manufacturing of RF welded and thermoformed vinyl products as well as fabric and foam containment products for many industrial, medical and commercial applications. Some other products that require containment, but are not limited to:
Products that require the containment of gel or similar substances are made using radio frequency welding technology in order to prevent breakage or spillage of the enclosed substance. Gel or liquid containment products need to be durable, contamination free and approved for human contact.
Radio frequency welding or heat sealing the seams in combination with the right materials renders gel- or liquid-filled products completely leak free for the life of the product. Most often, these soft-filled gel products are manufactured to a specific bursting strength.
Spill or semi-hazardous substance containment products most often need to have impervious seams. As the trend for lightweight and space-saving items continues, the construction of spill containment and other containment type items migrate toward collapsible and flexible uses. RF, HF and heat sealing processes are the ideal methods with which to construct flexible, impervious containment with strong, unbreakable and leak proof seams.
