FILMS AND SHEETS HAVING MICROLAYERS AND NANOLAYERS INCLUDING RECYCLED CONTENT

A polymeric film, sheet, or extrusion coating is formed as a multilayered structure having at least one A layer and at least one B layer. The polymeric film, sheet, or extrusion coating is able to include at least 30% recycled content resin while also exhibiting improved stiffness and strength relative to films with purely virgin polymers. One embodiment of the present invention further presents improved oxygen barrier properties relative to existing films, sheets, or extrusion coatings. Due to the strong structural properties, the polymeric film, sheet, or extrusion coating allows for the inclusion of recycled content into applications where recycled content has previously not been able to be included, such as flexible food, pharmaceutical, or cosmetics packaging.

Low adsorption sealant film, laminated body, and packaging bag

The invention provides a sealant film that is less likely to adsorb components formed of various types of organic compounds, has excellent heat sealing characteristics at 140° C., while having low heat sealing strength at 100° C. and being less likely for heat sealing layers to adhere to each other even when the film is used as a packaging bag and the content thereof is warmed in boiling water. The sealant film has at least one heat sealing layer consisting of a polyester component, wherein a heat sealing strength of the heat sealing layer being heat sealed to another heat sealing layer at 100° C. and 0.2 MPa for 2 seconds is 0-5 N/15 mm and at 140° C. and 0.2 MPa for 2 seconds is 8-30 N/15 mm, and a film density including all layers is 1.20 or more and less than 1.39.
