Carl R. Letendre is an accomplished inventor based in Fairport, NY (US). He has made significant contributions to the field of thermoplastic bag design, holding a total of 2 patents. His innovative approaches have led to the development of practical solutions for everyday packaging needs.

Latest Patents

Letendre's latest patents include a "Method of making easy open thermoplastic bag" and an "Integral handled layflat thermoplastic bag." The easy open bag features a thermoplastic film design with integral members that facilitate easy opening. This bag is manufactured from a flattened tube of thermoplastic material, which can be severed along independent phase-shifted sinusoidal oscillating paths. The design includes two opposed tie members that allow users to grasp and pull apart the bag for easy access. The tie members can also be tied together for convenient carrying.

The integral handled layflat thermoplastic bag involves a method for forming handle-containing bags in roll form. This process includes forming a continuous collapsed tube and creating pairs of closely spaced seals. A transverse line of weakness is formed between each pair of seals, allowing for the creation of loop handles and a bag mouth region upon removal of a cut-out region. This innovative method results in severable bags that are easy to use and transport.
