The production of ophthalmic glasses involves a series of precise processes that require the delicate handling of lenses made from both glass and organic materials. Avery Dennison Performance Tapes supports several of these critical steps with a series of specialist adhesive solutions for optical applications. This includes tapes for securing surface savers during the lens grinding process. The lens saver must attach both to the alloy (in liquid and solid forms) which fixes the lens position during the grinding, and to the lens itself to serve as a crucial protective shield between the alloy and fragile materials.
During the polishing process that ensures the lens delivers perfect transparency, felt pads are mounted to a support and attached to the lens surface. Here, Avery Dennison’s double-sided tapes provide perfect adhesion to both the felt and supports made from numerous materials such as aluminum and plastics. Lenses then make their way to opticians, who utilize lens blocking pads during the lens edging process that transforms the lens into the shape required for the customer’s chosen frame. This is where Avery Dennison’s double coated, shock absorbent PE foam tapes play their part – bonding the blocking pads to both lens and support.
Our high-performance adhesives offer reliable adhesion throughout the optical lens production process, with tapes suited for all forms of lens, alloys, supports and protective pads and lens savers used during various manufacturing stages
Avery Dennison can provide the right optical tape to suit your specific lens manufacturing processes. We can produce liner-free tapes which are compatible with certain types of machinery that cannot accommodate liners.
Tapes used in ophthalmic applications must be able to bond to curved lens structures and be able to withstand the stresses and vibrations involved with lens grinding, polishing and edge grinding.
Avery Dennison’s tape solutions are easy to apply and remove, and will not leave adhesive residue on lenses and other materials used in the manufacturing process. Furthermore, they can be die-cut into the precise shapes required by lens manufacturers.
You might say we hold it all together. Our business operates in the Avery Dennison tradition of breakthrough innovation, deep application expertise, and standard-setting customer service and collaboration.
