Latest Patents

One of Takuo Ohkubo's latest patents is focused on a low temperature heat shrinkable film and the process for producing it. This innovative film comprises a linear low density polyethylene resin with a short branched chain and a density of 0.935 g/cm³. The film exhibits properties such as a haze value of 5% or less, heat shrinkages at 90°C in the machine (M) and transverse (T) directions of 30% or more and 5% or less, respectively. Additionally, the shrinkage stress at 90°C in the M direction is 300 g/mm² or more. The production process involves drawing the film between two rolls with a diameter of 200 mm or less at an air gap of 10 mm or less, using a draw ratio of 3.0 to 6.0. This transparent film is characterized by excellent low temperature heat shrinkability, transparency, strength, and uniform film thickness.
