In the realm of radio frequency welding, there are a number of methods used to create strong seams that ultimately make quality leak proof products. Tear sealing is one such method. It is used to create products for a plethora of different industries, making it a very versatile service. Tear seals are used for materials that cannot be sealed and cut at the same time.
What is Tear Sealing?
Tear seals are radio frequency welded bonds that create a perforation-like seam on the outer perimeter of a weld, making it easy to simply tear off the excess material by hand. These seals are used to eliminate a final cutting step, saving time and potentially money in the long run. Tear seals aren’t specific to one particular industry, either, making them useful for many different companies and products. The best materials to use when creating tear seals are materials that are not stretchy or highly elastic, as stretching material may deteriorate the seam when trimming the excess. The best material to use for a tear seal operation is PVC film. Urethanes and other films with high elasticity do not perforate or tear seal very well.
What Makes Tear Seal Seam Welding Effective?
Tear seals are popular because of how efficient they are. They are typically used when a product’s dimension tolerances are not extremely tight. In other words, a product need not adhere to an extremely specific elongation factor or size guidelines in order to work within a larger product. Tear seals are generally the best choice when the materials involved are not stretchy or elastic-like, and when the size dimensions are not overly rigid.
