Latest Patents

Hongo's latest patents include a packaging bag that features a polyester-based multilayer film. This multilayer film consists of an innermost layer made from a biaxially stretched polyethylene terephthalate film, along with layers formed from polybutylene terephthalate and/or a blend of polyethylene terephthalate and polybutylene terephthalate. The unique aspect of this packaging bag is that the heat sealing portion of the film is amorphized or low-crystallized through laser light irradiation. The construction of the bag involves superimposing the innermost layers of the film and heat sealing the designated portions.

Another patent focuses on a film and pouch designed to enhance basic characteristics such as strength and barrier properties while ensuring good openability. This film includes a sealant layer and is formed with a cut guide line that features an impression on the surface of the sealant layer. In the pouch design, the films are arranged with the sealant layers facing each other, and the peripheral edges are heat-sealed. The cut guide line is strategically placed to extend across areas where heat sealing is not performed.
